U.S.-based Japanese automakers will run out of electronic components in five weeks
U.S.-based Japanese car makers have about five weeks before they will run short of sophisticated electronic components, Japan's consul-general said Tuesday.
"We are all concerned," Kuninori "Matz" Matsuda, said in a meeting with The Plain Dealer editorial board. "Right now most companies in the United States have about week's worth of parts in ic components stock and about another month's in transit."
Matsuda is stationed in Detroit. He is spending time in Ohio to talk about expanding Japanese manufacturing in the state. There are already 388 Japanese companies in Ohio that employ more than 56,000 people, he said.
Japanese are particularly interested in locating new facilities in northern Ohio, Matsuda said, because of its growing reputation in medical technology, advanced energy such as solar and wind, and materials science involving polymers.
The problem facing Japanese automakers here is that many of the high-tech electronics used in automobiles are currently made only in Japan. And some of those electronics factories were located in the area devastated by the March 11 earthquake and tsunami.
These companies are feverishly trying to re-configure their supply chains to keep the car companies supplied, Matsuda said. They are scrambling to ramp up production in their factories located in western Japan, which was unaffected by the earthquake, and may even attempt to change production to other countries.
More than 130,000 buildings were destroyed by three intense earthquakes and the tsunami that struck some areas closest to the sea within 15 minutes, he said. Because the devastated area in northeast Japan is remote and agricultural with few main roads, recovery efforts are far from over.
In areas affected by the quakes but not the tsunami, employees have continued to show up for work in an effort to get the plants back into production more quickly, he said.
"The recovery of land and air logistics will take time. But they are working very hard. Japanese workers don't go away," Matsuda said.

Detailed description about IC Parts LM339
I understand the knowledge froum a site,that is a Professional electronic components website,
Introduced a lot performance indicators about the model of ic components,also a lot of useful knowledge.It’s hqew.net,I Obtain these knowledge about electronic component from hqew.net.
I hope those are usefull for you.
The ic components LM339 series consists of four independent precision voltage comparators with an offset voltage specification as low as 2 mV max for all four comparators.
These were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage.

LM317A and LM317 Electrical Characteristics (Note 3)
The ic components LM317 and LM317 Electrical Characteristics follows:
Specifications with standard type face are for TJ = 25°C, and those with boldface type apply over full Operating Temperature
Range. Unless otherwise specified, VIN − VOUT = 5V, and IOUT = 10 mA.
The electronic components LM317 is capable of providing extremely good load regulation but a few precautions are needed to obtain maximum performance. The current set resistor connected between the
adjustment terminal and the output terminal (usually 240Ω) should be tied directly to the output (case) of the regulator rather than near the load. This eliminates line drops from appearing
effectively in series with the reference and degrading regulation. For example, a 15V regulator with 0.05Ω resistance between the regulator and load will have a load regulation due to line resistance of 0.05Ω × IL.
If the set resistor is connected near the load the effective line resistance will be 0.05Ω (1 + R2/R1) or in this case, 11.5 times worse.
Figure 2 shows the effect of resistance between the regulator and 240Ω set resistor.

The useful of dual variable power LM317 and LM7805
Do you now ic components LM317 and LM7805 principle and usage?
This project shows how to build a Dual Variable Power Supply using LM317 and LM7805. It has two different outputs.. one stable at 5V and one variable, rated at 1 ampere each. The power comes from a transformer. Schematic and PCB is available on Eagle format.
A lot of emphasis was put on making this power supply very stable, a big 4700uF cap takes care of the ripple, then come the regulators, after that a 220uF clean any noises that the regulator might have let pass. The polyester capacitors do a more subtle filtering.
