LONDON – Toshiba has announced that this month it will start production of white light emitting diodes intended for use by makers of general purpose and industrial lighting using Bridgelux technology.
The white LEDs are made using gallium nitride grown on 200-mm diameter wafers of silicon. Toshiba said it plans to ramp capacity up to 10 million LEDs per month and said it wants to secure a 10 percent market share by 2016.
Production of LED chips is typically done on 2- to 4-inch sapphire wafers. Bridgelux Inc. (Livermore, Calif.) developed a method of manufacturing gallium nitride LEDs on 200-mm silicon wafers, which provides a cost advantage. With backing for Bridgelux from Toshiba, that process was brought to Kaga Toshiba Electronics Corporation, a discrete products manufacturing facility in northern Japan. Plessey Semiconductors Ltd. (Plymouth, England) has also adopted a GaN-on-Si process for LED production but is presently ramping with 6-inch diameter wafers.
The first product of the Toshiba GaN-on-Si line is the TL1F1 series of LEDs that produce 112 lumens at 350-milliamps current. The packaged parts measure 6.4-mm by 5.0-m by 1.35-mm.
Another year of strong economic growth, improved employment and pent-up housing demand bodes well for most sellers in 2015, particularly in the Farm Belt and in energy-producing states such as Texas, North Dakota, Louisiana, Montana and Wyoming, and urban areas like Seattle, San Francisco, Los Angeles, Denver and Boston.
In fact, the National Association of Home Builders, or NAHB, predicts that the 2015 single-family home sector will outperform a strong 2014. There are cautions: Moody's predicts mortgage rates will rise from about 4 percent now to 6 percent by 2017.

The recovery has yet to arrive in many states, reinforcing the notion that real estate growth is regional. No one can accurately predict when this real estate uptick will end or how hard, or soft, a landing it will make. In the meantime, let proven fundamentals, applied with a few modern wrinkles, rule the day. Here are 10 tips for 2015 to help the real estate process.
More On Real Estate: 6 must-do's before buying a home How much house can you afford calculator 7 tips for picking a real estate agent 1 Create a news alert for "real estate" 1. Do sweat the small (cheap) stuff, sellers Little touches go a long way in the buyer's eye, starting logically with the entry. Trim bushes, wash walkways and change out trampled welcome mats. Inside, de-stink with candles and counter sprays, de-jam closets and de-clutter rooms, focusing keenly on kitchen counters. Hide scrub brushes and other fantasy-killing labor tools. Dust, wax, scrub toilets, wash windows, test and clean lights, put out fresh towels, winnow family mementos, harness or hide that avalanche of toys, remove prescription drugs from medicine cabinets and police the yard for "pet bombs." It's time well-spent.
2. Take note(s), buyers In a whirlwind house-hunting tour of several properties, buyers benefit by keeping a pro-and-con checklist of each home they visit. Otherwise, the features of several homes tend to blend together in a tired brain by day's end. Creating a rating scale of 1 to 10 also helps, as does carrying a checklist of specific features that you seek in an ideal home.
3. Sell by season Though spring is optimal, home selling is a year-round sport. Use seasonal accents to make buyers linger longer.

'Big data' is everywhere, so tap in While local knowledge and old-school networking will always be valuable, the latest technology lets agents offer much more. Some agencies offer "livability" ratings by ranking and contrasting neighborhoods by air quality, traffic choke points and specific data on a home's energy efficiency. In 2013, the National Association of Realtors introduced its Predictive Analytics group. Banks already use "big data" to gauge the worth of foreclosures and short sales, and mobile apps now offer it for consumer and agent use. Ask agents if they offer this and other edgy technology such as high-definition aerial footage shot by drones. Should your grandiose home merit that, go big!
6. Transparency equals trust Buyers will certainly enlist inspectors to twice-over your home, Mr. Seller. So instead of inviting disappointment, delay and distrust, go transparent with your own presale inspection. It's far better to know now about issues with the plumbing, HVAC (heating, ventilating and air conditioning), foundation, electrical systems and roof. Provide the buyer a copy of the inspection along with repair receipts, and explain if or how you've adjusted your price accordingly. Buyers appreciate candor.
7. Math versus ego Too often, buyers get caught up in win-at-all-costs negotiation. They'll stubbornly let as little as a few grand lock them out of the right house. At an interest rate of 4.5 percent, the difference between paying $200,000 and $195,000 -- assuming 1.25 percent property tax and 15 percent down -- is only about $25 per month on a 30-year mortgage, or about the cost of lunch for two at a fast-casual eatery, before the tip. Don't let that ruin your chances at your dream home.
8. Retain mineral rights With so many giant natural-gas fields (shales) in play across the U.S. and new ones pending, homeowners should exercise "seller's market" clout to retain mineral rights. While that intent needn't even be mentioned in the sales contract in some states, it's always safest to note it, provided the buyer doesn't protest. Avoid that scenario by conveying those rights to a trustworthy relative or to an energy company buying them before putting the house on the block. "Mineral rights? Oh, so sorry, I no longer own them."
9. Buying? Then cool it for a while Refrain from making big capital purchases like a new car, opening new credit cards or amassing big chunks of other new debt before buying a home. These raise your debt-to-income ratio, which lenders examine to determine the mortgage amount you can afford. Also avoid moving large sums of money around, changing banks, changing jobs and becoming self-employed before buying a home.
10. The price is right Trite, you say? Perhaps. But accurate home pricing from the outset never goes out of style because it sells homes. Some agents advise sellers to overprice because inventory is low. Others say go below market to spur a bidding war. Don't get caught up in pricing games.
In this case we have a circuit that worked well at one operating point, but reliably self-destructed at another operating point. The active load circuits were the same. The transistor power dissipation was the same. The engineer pulls out his hair and cries out to the heavens: ‘What is going on?’
