Title: Semiconductor device
Inventor: BABA YOSHIAKI
IPC: H01L29/74
Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device having a small on-resistance and high pressure resistance in IGBT, by causing a first depletion layer formed by junction between a base region and a base layer to be in contact with a second depletion layer formed by junction between an island region and the base layer. SOLUTION: A p-type diffusion layer 15 is formed between base regions 4. A depletion layer formed on the side of an n-type base layer 3 by junction between the p-type diffusion layer 15 and the n-type base layer 3 is caused to be in contact with a depletion layer formed on the side of the n-type base layer 3 by junction between the p-type base region 4 and the n-type base layer. Thus, a corner portion of the depletion layer is eliminated, thereby smoothing the shape of the depletion layer 16. Therefore, by preventing an electric field applied to the depletion layer from concentrating at the corner portion, the pressure resistance at the off time may be improved in comparison with a conventional IGBT which has no p-type diffusion layer 15.

The interelectrode distances of the adjacent electrodes 8, 8 for electric field impression are changed to, for example, arbitrary stepping or functional shapes in order to periodically change the above-mentioned distances. The arbitrary voltage is impressed to the counter electrodes 8. The filter of different central wavelengths is obtd. if the interelectrode distances of the counter electrodes 8 for electric field impression are formed to the arbitrary stepping shape. The filtering at arbitrary ratios is possible according to the interelectrode shapes if the interelectrode distances of the adjacent electrodes are made into the functional shape. The high-accuracy color resolving power is obtd. in this way.

Title: Etching of semiconductor substrate
Inventor: MIWA MASAHIDE
IPC: H01L21/306
Filed: 1986-12-23
Abstract: PURPOSE:To improve the yield of a product and to reduce its cost by freely rotating a wafer holder for containing a silicon wafer in an etching tank, and uniformizing temperature distribution and concentration distribution in an etchant. CONSTITUTION:When an etching carrier 1 freely rotates in an etching tank 6, a silicon wafer 5 contained in a wafer holder 2 rotates in an etchant 7 made of alkaline aqueous solution and alcohol. When the etchant 7 is heated to a predetermined temperature, a natural convection is generated in the tank 6, and the convection is further accelerated by air bubbles due to reaction heat and reaction gas by etching the wafer 5. A stationary plate 3 is affected by the convection to rotate the carrier 1 and to agitate the etchant 7, thereby uniformizing temperature distribution and concentration distribution. Thus, the yield of a product can be enhanced, and its cost can be reduced.

Title: Film for thermal transfer recording reader tape
Inventor: HASEGAWA KINJI
IPC: B41J31/00
Filed: 1988-12-15
Abstract: PURPOSE:To obtain high heat resistance which withstands thermal transfer recording for high-speed printing by making film of biaxially oriented thermoplastic polyether ketone resin with the sum of a longitudinal F-5 value and a lateral F-5 value being over a specific value and a coefficient of thermal shrinkage below a specific value at 150 deg.C. CONSTITUTION:Polyether ketone resin film is biaxially oriented film with the sum of a longitudinal F-5 value and a lateral F-5 value being 22kg/mm<2> or more. If this sum of the F-5 value is not more than 22kg/mm<2>, the running film becomes bent or folded. The preferable coefficient of thermal shrinkage at 150 deg.C is 3.0% or less. If the coefficient of thermal shrinkage is 3% or more, the film becomes thermally shrinked when it comes in contact with a heating head, and the tape becomes folded, resulting in a deteriorated sliding property. To ensure that the coefficient of thermal shrinkage is 3.0% or less, the biaxially elongated film has only to be thermally fixed at (Tg + 70) deg.C. Polyether ketone film is thermally fixed at 200 to 350 deg.C.

Abstract: PURPOSE:To allow the user to identify the hot water supply temperature in advance whichever tap he or she may desire to to use to supply the hot water so as to prevent burn injuries due to a careless opening of the tap by imposing that only one remote controller out of a plurality of remote controllers becomes effective and nullifying all others at the time of switching the hot water supply temperature, and causing only the indicator lamps for hot water supply temperature to be illuminated on the nullified remote controllers. CONSTITUTION:At the time of switching the hot water supply temperature, only one of a plurality of remote controllers A, B is always made effective and others are nullified. On the temperature indicator 12 on the effective remote controller A, all the lamps from the 'low' to the set level are illuminated, and, on the temperature indicators on the nullified remote controllers B, only the lamp for the set level is illuminated. In this constitution, the set temperature for hot water delivery is indicated not only on the prioritized remote controller A but also on the non-prioritized remote controllers B, and so, the hot water supply temperature can be identified in advance whichever tap is to be used, preventing burn injuries due to a careless opening of the tap.

Abstract: PURPOSE:To prevent a fixed noise from being conspicuous on a picture by providing a memory to store a fixed noise signal, which is generated by the dark current of a CCD, and subtracting the fixed noise signal, which comes from the memory, from a video signal. CONSTITUTION:A signal to be accumulated to a noise memory 9 is defined not a normal video signal but the signal only of the dark current generated by a CCD synthesizer 1, for example, the fixed noise signal in a condition that a camera is covered with a lens cap. There is a writing switch 12 in the memory 9 and by pushing this switch, the fixed noise signal of TV picture for one frame is stored.
