Patent JP-H0197102-A (JP)
Title: Controller for electric rolling stock
Inventor: YAMAMOTO SHIROJI
IPC: B60L9/24
Filed: 1987-10-08
Abstract: PURPOSE:To stabilize the driving control of an induction motor, by lowering the input voltage of an inverter on the speed control of one pulse mode in which the output voltage of an inverter is set at the maximum when slipping or sliding is generated. CONSTITUTION:By fundamental FIC(filter capacitor) voltage command 23 and an actual FIC voltage feedback value 25, arithmetic is performed on the level of filter capacitor voltage on FIC voltage controlling degree arithmetic 27. Normally, the output voltage of the voltage controlling degree arithmetic 27 is turned into an FIC voltage controlling degree command value 29. In the meantime, when slipping is generated during operation of an electric rolling stock, then slip detecting signal 33 comes to H. Besides, when a pulse is in one pulse mode, then switches 41, 45 are switched to 1. When the switches are changed over, then by an arithmetic unit 51, the output value of a sampling hold circuit 49 is subtracted at every 1 sampling time, and the voltage controlling degree command value 29 is computed.

Title: Semiconductor device
Inventor: OZAKI ATSUSHI
IPC: H01L27/092
Filed: 1990-09-20
Abstract: PURPOSE:To reduce percent defective to be generated due to a punch throw by a method wherein a source side of an N channel transistor is connected to a Vcc line through a P channel transistor. CONSTITUTION:A P channel transistor 2 exists between a Vcc lime 1 and an N channel transistor 3. Even if a punch throw occurs at a contact part between the Vcc line 1 and the P channel transistor 2 and aluminum happens to penetrate, since a P channel transistor 12 exists within an island, it penetrates up to the island. However there are scarcely few possibilities that it penetrates up to a substrate, so that it can be prevented to short out between the Vcc line and the substrate.

Abstract: PROBLEM TO BE SOLVED: To prevent crystalline grains in a base material from being coarsened at the time of high temp. annealing and to prevent the occurrence of surface roughing, such as orange peel, by providing a low carbon steel as a base material with a specific composition which contains C, N, Ti, and B and in which the contents of respective elements satisfy specific relationships. SOLUTION: The low carbon steel as a base material has a composition which contains, by weight, 0.015-0.06% C, 0-0.010% N, 0.10-0.40% Ti, and 0.0005-0.0050% B and in which (Ti-3.4N)/4C >=0.6 and Ti×C=2.8×(1/1,000) to 13.5×(1/1,000) are satisfied, where Ti, N, and C in the inequality and the equation represent respective weight percentages of the elements. The coarsening of the structure of the base material can be prevented by properly regulating the α/γ transformation point. For this purpose, the addition of B having a great influence on the α/γ transformation point is done and also the remelting behavior of TiC at the time of annealing is controlled to properly regulate the amount of solid solution C resultant from the remelting.

Patent JP-S62113431-A (JP)
Title: Manufacture of semiconductor device
Inventor: KANAZAWA HISATOMO
IPC: H01L21/322
Filed: 1985-11-13
Abstract: PURPOSE:To realize a semiconductor device stable in performance characteristics by a method wherein a silicon substrate provided with a P-N junction is first diffused with gold at a prescribed high temperature and then subjected to a second heat treatment at a lower temperature as prescribed. CONSTITUTION:Au is diffused into silicon crystals at temperatures 900-1,000 deg.C. A second heat treatment is accomplished at a temperature affecting only the reverse recovery time but not the forward voltage withstanding capability or backward voltage withstanding capability, that is, at a temperature of 700-800 deg.C. The Au diffused into a silicon crystal beyond the solid solution limit, because the Au is low in the degree of solid solution in a silicon crystal, precipitates during cooling at crystal lattice defects. A second heating causes the Au precipitating at lattice defects to return into between or into lattices, increasing the quantity of Au solved into the silicon crystals. This leads to a reduction approximately in half of the dispersion (a) in reverse recovery time as compared with the dispersion (b) of the same in a conventional design.
