Black Friday: Canadians Stream to U.S. Sales

NIAGARA FALLS, N.Y.-Canadians streamed across the border on Thursday to take advantage of

Black Friday

sales that now begin on Thanksgiving Day in the U.S.

Mark O'Donnell, 32, of Brampton, and his wife Georgette O'Donnell, 32, were first in line in front of a Target in Niagara Falls on Thursday afternoon. They got there at 10 a.m., ten hours in advance of the 8 p.m. opening.

It was literally freezing cold and Mark was sitting on a chair on the pavement to the left of the doors, sharing a blanket with an Oakville man who until Thursday morning had been a stranger.

"I stand in line for sports, I go to the Bills games. I know how to sit in the cold outside," said O'Donnell.

Sitting beside him was Jay Husack, 39, of Oakville. The men were watching football on a computer hooked up to the O'Donnell family car.

Black Friday shopping takes hold in Canada

Malls across Canada launch new Black Friday hours

Nearly half of Canadians plan to shop on Black Friday

All three were lined up to buy electronics. Georgette was hoping to get a Nintento 3DS XL game system for the advertised discount price of $150. It was recently selling at $199 on sale at Future Shop in Toronto.

Beside them was a veteran of Black Friday, Jojo Kornacki, 44, who said she routinely camps out in front of Target on Black Friday. On Thursday, she was wearing a green and red felt elf hat and sitting next to a portable heater.

She was done family Thanksgiving, held at 1 p.m. at her mother's house, and was hoping to snag a 50-inch Emerson HDTV for $228. Once, she said, she sold her spot in line for $225 cash.

"There was a blizzard. The snow was going sideways," said Kornacki, who lives in Niagara Falls, N.Y.

She said police typically arrive close to opening and control the number of people who enter the store at any given time.

A police car was parked in front of a nearby Walmart and a fleet of security personnel guided shoppers through a zig-zag crowd-control barrier.

Inside the store, the long line-up for the mini iPad special was made up in large part of Canadians, including friends Katelyn Koluk, 25, a teacher from Niagara Falls, Dori Tofani, 42, and Laura Belcastro, 25.

They arrived at the Walmart before 2 p.m. to line up for the mini iPad selling for $299. That price included a bonus $100 Walmart gift card, making it worth driving in for them.

They are also veterans of the Black Friday shop. Despite horror stories of people being crushed and trampled by crowds vying for scarce items - door-crashers sold at deep discount, but in relatively small quantities - Koluk said she's never run into any trouble.

"Personally I've never been in any kind of danger," she said.

The Walmart is a 24-7 store, meaning it is open day and night all week, and it did not close for Thanksgiving Day. It remained open and those who arrived early for the specials - which landed at 6 p.m. and 8 p.m. and again at 8 a.m. on Friday - were allowed to line up inside. Wristbands were issued at about 4 p.m., and those who snagged one were allowed to leave the store and come back for merchandise pick-up between 6-8 p.m., and were guaranteed a mini-iPad.

Items that were to go on special later in the day were shrink-wrapped and plastered with signs advising customers that they could not be processed at the cash until later in the evening.

Opening times at stores and malls in Niagara and Buffalo were staggered across Thursday evening and Friday morning. But not everyone in the US is happy with the fact that Black Friday is bleeding into what was once a sacred family holiday.

It was reported that Sears Hometown store owner Holly Cassiano, in Plymouth, N. H., rejected the order from head office to open at 7 p.m. on Thanksgiving.

"We are not going to let corporate retailers rule over our family values and take this away," she told a local news outlet. "I value my employees enough that I wouldn't have them have to work on a day that's meant for family."

Portable Heaters - Buy a Radiant Space Heater
Portable heaters, as the name implies, are heaters that you can move around from room to room or take it with you to your office - anywhere you need it. If your HVAC (heating, ventilating, and air conditioning) system at home isn't doing the job well or it's old and inefficient, or you just want to save money on your energy bill, then a portable heater may be just what you need to stay warm this winter.Most heaters have fans that move the air over a heated coil. If the heater didn't have the fan, the coil could heat up too much and pose a fire hazard - not something you want in your home. The problem with these types of heaters, though, is that the fans tend to make you cooler which is quite ironic when the purpose is to warm you up, not cool you off. Therein lies a conflict with these traditional types of portable heaters - their purpose is to generate heat, but their design (the inclusion of the fan) cools you down. Radiant HeatersThe answer is to get a radiant heater. Radiant heaters don't use fans; instead they use parabolic reflectors, with a heating element at the focal point, or something similar. Rather than by convection (the use of a fan), these radiative heaters spread heat by radiating it rather than by convection (air circulation from a fan.) Radiant heaters are much more efficient than conventional heaters as well, and the heat they produce feels more natural because the heat is supplied the same way the sun supplies it - through radiation.Remember that radiant heaters, just as conventional heaters with fans, can be dangerous if not used properly, so be sure to read the instructions and adhere to them.Portable heaters should not be used where children are present.More Options:Of course there are obvious options to staying warm in the winter, like layering your clothes or snuggling up with a warm blanket. Another great option to keep warm in your home during winter season is to buy a heated blanket - they're comfortable and provide a really soothing warmth. Heated blankets also make great Christmas/Hanukkah gifts for loved ones!

Gas Heaters and TV Sets Recalled Over Safety Fears
CALOR Gas is urgently trying to recall 800 portable heaters, which could emit deadly carbon monoxide. The fault has been found in Royal Classic, Calor Classic and Calor Compact portable heaters purchased since August. Calor said the heaters had been imported from UniPart UK by a number of Irish distributors. Retailers here had been notified of the fault and sales had been suspended. Any Royal Classic, Calor Classic or Calor Compact portable heater bought after August 1 should be immediately switched off and returned to the point of purchase. The statement downplayed the danger the affected machines pose with a spokesman saying there was a "perceived minimal risk" and that the emissions would be "marginally above the allowed levels". Anyone who has purchased one of the heaters will be offered a replacement product where stocks allow or a full refund. A list of the serial numbers of the faulty machines and where to find the numbers on the machines is available on Calor's website www.calorgas.ie. There is also a hotline — 1850 812 470 in the Republic or 028 9045 5588 in the North — for customers who are worried about their heaters. Meanwhile, Lidl has recalled a number of 24-inch flat-screen television sets due to the risk of an electric shock. The Targa Sivercrest televisions are understood to have a short-circuiting risk. The TVs went on sale on November 11, 2010. "Under no circumstances should customers attempt to fix this device. Instead they should return the product to their local Lidl where they will receive a full refund. A receipt is not required," Lidl said. try _402_S
Your Good Health: Diabetes Medication Has Side-effects
Dear Dr. Roach: Is Januvia an effective drug for diabetes? What are the side-effects?M.A.A. Sitagliptin (Januvia) is an oral medication for diabetes mellitus. The way it works is complicated: It inhibits a molecule called DPP-4, which causes an increase in another molecule called glucagon-like peptide 1. GLP-1 causes decreased secretion of the anti-insulin hormone glucagon, so the net effect of Januvia is to block a hormone that opposes insulin. It might decrease hunger, and has a modest effect on blood sugar: In most clinical trials, it reduces the A1C level by 0.5 to one point. It is unlikely, by itself, to cause abnormally low blood sugars. Side-effects include joint aches, which usually go away on stopping the medication. Allergic reactions are possible as well. In clinical trials, there were reports of pancreatitis, so any abdominal pain should be reported to your doctor.Dear Dr. Roach: My son doesn't like to visit me, as my home is too hot for him. I cannot visit him either, as I practically need a snowsuit in his home from fall through spring. Even in my own house, I can't bathe without a portable heater in the bathroom. I am concerned about low thyroid levels.E.W. Although it's possible your son is the one who is too warm, it sounds more likely that it's you who is abnormally sensitive to cold. Cold intolerance is common in the elderly, especially in those who do not have a lot of body fat. However, you are quite right that it is a common sign of low thyroid levels, and I certainly think you should get yours tested. However, there are other conditions, both common and less so, that can show up in people with sensitivity to the cold. One is anemia. There are many causes of anemia, and when you see your doctor to get your thyroid checked, he or she probably will test for that as well. Rare causes, like Addison's disease (an inability to make cortisone) and disease of the hypothalamus, which regulates body temperature, are much less common.Dear Dr. Roach: Can indigestion (possibly due to gas) cause hip pain or sciatica? I always experience these two conditions simultaneously. I get relief by belching, walking and, when all else fails, milk of magnesia. I suspect that the gas is exerting pressure on the sciatic nerve and thereby causing the hip pain. Is there any medical history to support this suspicion? Or is there another explanation? Thank you.E.J. I don't see a direct connection between intestinal distention and nerve pain in the back or hip. The sciatic nerve — which is a very large structure, nearly the size of your little finger — travels through the sciatic foramen in the hip bone. It can be compressed by structures in the hip and back, such as a herniated disc or the piriformis muscle. The contents of the abdomen are far above the sciatic nerve. People with sciatic nerve pain more typically feel pain radiating down the back of the leg into the foot. The best I can come up with is that, often, people with abdominal distention change their body position, sometimes bending over to relieve the pressure, and this might cause the sciatic nerve, or a different nerve going to the hip, to be pressed on.Dr. Roach regrets that he is unable to answer individual letters, but will incorporate them in the column whenever possible. Readers may email questions to.
How to Buy and Use Portable Heaters
By MICHAEL DECOURCY HINDSJAN. 22, 1981 This is a digitized version of an article from The Times's print archive, before the start of online publication in 1996. To preserve these articles as they originally appeared, The Times does not alter, edit or update them. Occasionally the digitization process introduces transcription errors or other problems. Please send reports of such problems to . PORTABLE electric heaters consume a lot of electricity, but they put out a lot of heat and this may interest tenants in poorly heated apartments as well as thrifty homeowners who want to save on central heating. Task heating, as it is called, produces the heat where you need it and when you need it. In addition, the new quartz models are radiant heaters and work like a fire in a fireplace: warming people directly without wasting energy heating the air.Before running out and buying a portable heater there are a few things to keep in mind. Using the devices for heating large areas ''will cost like sin,'' according to a spokesman for the Consolidated Edison Company. The average 1,500-watt models cost about 17 cents an hour to operate, or about $21 to run four hours a day for a month.These heaters often use 12.5 amps -which means that nothing else can be operated from the same outlet and, in most older apartments, that probably few or no other major electric appliances can be used at the same time.The heaters can also be very dangerous. It is not a good idea to use the electric devices in bathrooms, since insulation on the cords could deteriorate and cause shocks. If there are children or animals, additional caution must be taken. Buy only heaters that have closely woven grilles over the live elements, or heaters with sealed elements.AdvertisementSeveral types of heaters are available. The most common portables radiate heat from the electric elements as well as convect heat through the air with the assistance of a small fan. These heaters are usually small boxy things or long, low ''baseboard'' models. These combination heaters are good for warming a seated person, but not so good at heating a whole room.AdvertisementConvection-only models, some of which look like small steam radiators, are better for heating rooms, but not so good for spot heating.Consumer Reports magazine in its November 1980 issue rated the Markel 57T the best convection model of those tested. Radiant-only models, such as the quartz heaters that operate at very high temperatures, are excellent at warming specific human targets.The magazine rated only two quartz heaters and found both to be excellent spot heaters, but only fair room heaters. The ($94 listpriced) Presto 07870 was rated acceptable, but the ($90 list-priced) Boekamp 101P was not rated acceptable, because it ignited a piece of cloth draped over its grille.The most practical heater, according to magazine's testers, is an upright combination heater. Rated best were the Presto 07840 (which lists at $66) and the Arvin 30H2001 (which lists at $43 and is also available for $28 plus shipping through J. C. Penney's Catalogue, No. 0316). Less portable, but good heaters, are these baseboard models: Edison 324033 (which lists for $53) and the Titan BB42A (which lists for $56).Local suppliers of electric heaters are listed in the Yellow Pages under ''Appliances-Household-Small-Dealers.'' Most dealers carry only a few models, but here is a sampling of companies that offer a larger selection:Gracious Home, 1220 Third Avenue at 70th Street, (535-2033), sells a wide variety of heaters, from a $25 Arvin to a $180 Thermomate baseboard heater.Sam Diamond, 114 Fulton Street, between Nassau and Williams Streets, (227-1422), sells the recommended Presto 07870 quartz or a Boekamp quartz for $59.99; a smaller Arvin quartz for $49.95; a Patton, for $39.95.S. Feldman Housewares Inc., 1304 Madison Avenue at 93d Street, (289-3961) carries the boxy Markel 198TS, with a lifetime guarantee on the heating element, for $60, and a Titan at $31.99.AdvertisementMay's, 14th Street and Broadway (fifth floor), (677-4000) sells the Presto quartz 07870 for $80 and the Titan BB42A for $50. American Home Center Inc., 206 First Avenue at 30th Street, (683-3616), sells a few models, from $35 to $60. Bloom & Krup, 206 First Avenue at 12th Street, (673-2760), sells the Titan BB42A for $39.95, Arvin quartz for $49.95 and the Markel 198Ts for $49.95.Hammacher Schlemmer, 147 East 57th Street, (421-9000), a desk-top heater for $29.95, and a baseboard heater for $44.95. Macy's, in the Cellar, (695-4400), carries about 15 models, including the Patton, Presto and Delongi. All Abraham & Straus stores, including the one at 420 Fulton Street, Brooklyn, (875-7200), carry the Presto quartz for $88.99, the Arvin Quartz for $49.99 and the Intertherm baseboard heater for $134.99.Electric Appliance Rental and Sales, second floor of 40 West 29th Street, (686-8884), rents the Markel 198TS for $10 a weekend or $20 a week and permits customers to buy the heater for $53.95 with the option of converting the sale into a rental with a pro-rated refund.A version of this article appears in print on January 22, 1981, on Page C00003 of the National edition with the headline: HOW TO BUY AND USE PORTABLE HEATERS.

Office Air Conditioning Biased Against Women, Says ScienceOffice Air Conditioning Biased Against Wom
There may be no snow on the ground but in offices across the city women are saying it feels like Christmas in August.They are wrapping themselves in wool blankets and plugging in heaters below their desks to counter the air-conditioned chill in their cubicles. Meanwhile, male colleagues — many oblivious to the cold — tease them about the extra layers.Yes, women have long suspected the gender divide encompasses air conditioning. Now, after years of grumbling, science suggests that might be true.A recent study says that "females prefer a higher room temperature than males in home and office situations," but thermostats in offices are still set to satisfy the average 154-pound, 40-year-old man whose comfort was a priority in the 1960s when standards were drawn up. Researchers at Maastricht University in the Netherlands, in the course of studying energy consumption in buildings, also found that offices should "reduce gender-discriminating bias in thermal comfort predictions."Their study looked at women who work while seated and wearing light clothing. The researchers found the women had metabolic rates 20 to 32 per cent lower than that of male workers — for whom air conditioning levels are set. Their findings don't surprise Dr. Paula Harvey, interim chief of medicine at Toronto's Women's College Hospital.She keeps two scarves and an extra jacket behind her own office door. Her nearby assistant has a desk heater, and one of the hospital's office managers is known to rock a shawl atop her outfits.Sometimes, Harvey said, the difference in the way that men and women perceive temperature comes down to the way we dress — women are likelier to have bare legs and sleeveless blouses, while the dress shirts, suits and pants worn by men cover more skin.Plus, she said, most men have a higher metabolic rate than women, which often means a higher body temperature.There are exceptions, of course, based on body types. Some men feel just as cold as their female colleagues, and some women are immune to frigid air conditioning. But overall it explains why the average woman with a low metabolism is no stranger to the office chills.When freelance television producer Shy Ahmed heard of this, she said it explained why she totes a portable heater to every office where she works, piles on the sweaters and sips lots of hot tea and soup at her desk."I feel so lucky to live in a place where we get four seasons … so I don't get why, when we get great hot summer days, the temperature is set so mind-numbingly low in most indoor places," she told the Star in an email.But she doesn't let the air conditioning or coworkers' mocking get her down — she knows she'll have the last laugh."Even though I get teased about my block heater, there is always a point in time when everyone wants to borrow it."Four women feeling the cold at GTA offices:Desiree Buitenbos: Marketing agency employee Desiree Buitenbos always keeps a sweater on her chair at work. She once complained when the office was only 16C — her fingers were so cold she could barely type.Dr. Jessica Kim: Jessica Kim has yet to find a way to keep warm in her air-conditioned office without wearing shawls or a sweater.Iris Jacobson: Next time you visit career counsellor Iris Jacobson's office, look for her collection of sweaters and shawls and the portable heater — her weapons in a battle against the big chill.

Her nearby assistant has a desk heater, and one of the hospital's office managers is known to rock a shawl atop her outfits.Sometimes, Harvey said, the difference in the way that men and women perceive temperature comes down to the way we dress — women are likelier to have bare legs and sleeveless blouses, while the dress shirts, suits and pants worn by men cover more skin.Plus, she said, most men have a higher metabolic rate than women, which often means a higher body temperature.There are exceptions, of course, based on body types. Some men feel just as cold as their female colleagues, and some women are immune to frigid air conditioning. But overall it explains why the average woman with a low metabolism is no stranger to the office chills.When freelance television producer Shy Ahmed heard of this, she said it explained why she totes a portable heater to every office where she works, piles on the sweaters and sips lots of hot tea and soup at her desk."I feel so lucky to live in a place where we get four seasons … so I don't get why, when we get great hot summer days, the temperature is set so mind-numbingly low in most indoor places," she told the Star in an email.But she doesn't let the air conditioning or coworkers' mocking get her down — she knows she'll have the last laugh."Even though I get teased about my block heater, there is always a point in time when everyone wants to borrow it."Four women feeling the cold at GTA offices:Desiree Buitenbos: Marketing agency employee Desiree Buitenbos always keeps a sweater on her chair at work. She once complained when the office was only 16C — her fingers were so cold she could barely type.Dr. Jessica Kim: Jessica Kim has yet to find a way to keep warm in her air-conditioned office without wearing shawls or a sweater.Iris Jacobson: Next time you visit career counsellor Iris Jacobson's office, look for her collection of sweaters and shawls and the portable heater — her weapons in a battle against the big chill.

This means that if we don't replace them every year then they will only be running for a few years. Solar street lights are really nice because they are easy to install and use. They also have some built-in cameras that can record images on them.In general, we can say that the overall system performance of solar street lights is better than in general. For example, if you are planning to build a home or have an emergency service call 911, then it is important to use a single bulb and replace it every two years. This will save you a lot of money in the long run. However, there are some other factors that affect the overall system performance. The most important thing is to know what kind of bulb you are using and what kind of bulb you are using.
IGBT of Fuji Motor Electronic Equipment Technology
IGBT of Fuji Motor Electronic Equipment Technology
The IGBT technology of Fuji motor and electronic equipment technology has been commercialized since 1988 and has been supplied in the market so far. Figure 1-3 shows the development process and application technology of IGBT products from the first generation to the fifth generation. Epitaxial wafers are used in the first to third generation IGBT, and the characteristics are improved by optimizing life cycle control and refinement technology of IGBT. Then, the fourth and fifth generation products have achieved significant characteristic improvement through the transition from epitaxial wafer to FZ (floating zone) wafer. In this regard, the design policy of IGBT has changed greatly compared with the past.Firstly, the basic design idea of IGBT using epitaxial wafer (series products up to 600V of the third to fourth generation, called "breakdown type") is as follows. In order to realize the low-pass state voltage during IGBT conduction, a large number of carriers are injected from the collector side to fill the IGBT with high concentration carriers. In addition, the n-buffer layer specially set to maintain the high voltage forms a very thin n-layer, so as to realize the low-pass state voltage. In order to realize fast exchange, life cycle control technology aiming at the rapid disappearance of carriers filled in IGBT is also adopted (through these, low exchange loss (eoff) can also be realized). However, once the life cycle control technology is applied, even in the normal on state, due to the effect of this technology (the carrier transport efficiency decreases), there is a problem of increasing the on state voltage, which can be solved by further high carrier injection.In short, the basic design concept of IGBT using epitaxial wafer technology can be simply summarized as "high injection and low transmission efficiency". In contrast, IGBTs using FZ wafers (series after the fourth generation 1200V) adopt a reverse basic design to inhibit the injection of carriers from the collector side and improve the transmission efficiency by reducing the injection efficiency. In the above-mentioned design concept of IGBT using epitaxial wafer "high injection and low transmission efficiency", the carriers that are not easy to be injected are forcibly suppressed through the control of life cycle, which not only limits the improvement of characteristics, but also increases the standard deviation of on-state voltage characteristics through the control of life cycle, It is very disadvantageous to the large capacity required for parallel use with increasing requirements in recent years. The technology developed to overcome this problem is a new IGBT using FZ chip (NPT: non punch through (used from the fourth generation IGBT) / FS: field stop (used from the fifth generation IGBT) - IGBT). The IGBT does not adopt life cycle control. Its basic design idea is to control the impurity concentration of the collector (P layer), so as to inhibit the carrier injection efficiency. However, in order to realize the characteristics superior to the IGBT using epitaxial wafer, it is also required to realize more than one hundred for the 1200V high voltage resistant series IGBT μ M (the thickness of n-layer in NPT and fs-igbt using FZ wafer ≈ the thickness of chip (wafer). The thinner the thickness, the lower the on state voltage can be generated). In short, it is not too much to call the development of IGBT using FZ chip a challenge to chip thickness.Fuji electric and electronic equipment technology has solved these problems. Starting from the fourth generation 1200V series - IGBT, it has realized the commercialization of "s series" constructed by FZ chip NPT. In addition, 600V series technology with higher thickness requirements is further developed, and 600v-u2 series (fifth generation) is being commercialized. In addition, in 1200V series - the fifth generation "U Series", in order to improve the performance better than s series, NPT structure has been changed to FS structure.The so-called FS structure does not use the life cycle control technology. While following the basic design concept of "low injection and high transport efficiency" of carriers, an n buffer layer to maintain voltage is set on the FZ wafer, so as to realize the IGBT structure thinner than the NPT structure. Through this change, 1200v-u series realizes the low on state voltage characteristic better than s series, and completes its commercialization. In addition, this technology is also used in 1700V series high voltage withstand series, and is also starting to be commercialized.Figure 1-3 changes of Fuji motor electronic equipment IGBT application technologyIn addition, Fuji electric and electronic equipment technology is also refining the surface structure indispensable for the improvement of IGBT characteristics (IGBT is formed by multiple IGBT plates. Through refinement, the more plates, the more low on-state voltage can be realized). Up to the fourth generation products, the planar structure (the structure of planar IGBT) has been used to promote refinement, so as to improve the characteristics. However, starting from the fifth generation products - 1200 and 1700V series, the grooved IGBT technology slotted on the Si surface and constituting IGBT has broken the subtle technical barrier and achieved unprecedented characteristic improvement. Figure 1-4 shows the change of characteristic improvement of 1200V series.Figure 1-4 improvement of balance characteristics
