Title: Power window motor control device
IPC: E05F15/16
Filed: 1992-03-18
Abstract: PURPOSE:To reduce malfunctions by preventing a motor from being driven unless the manual actuating contact is turned on in the automatic running mode, thereby making an arrangement that the motor may not be driven in the automatic mode even when only the automatic actuating contact is turned on due to the defective insulation of the contact. CONSTITUTION:A motor 6 is not driven and malfunctions are reduced thereby when only automatic actuating contacts 2a, 2d are turned on due to a defective insulation or the like by making an arrangement that the motor may not be driven unless the manual actuating contacts 2b, 2c are also tuned on in the automatic actuating mode.

Title: Inverter circuit
Inventor: FUKUI HIROSHI
IPC: H02M7/515
Filed: 1980-07-11
Abstract: PURPOSE:To protect a gate turn off thyristor GTO as well as to block the spreading of a short-circuit trouble for the subject inverter circuit by a method wherein the voltage applied to the GTO is reduced when the short-circuit trouble is encountered and an overcurrent is broken by the GTO. CONSTITUTION:When the inverter short-circuit trouble takes place, the overcurrent flowing at that time is detected, a thyristor 16 is turned on and an off signal is given to the GTO (GT01 and GT02). The current of a DC power source 12 runs to the GTO and the applied voltage on the input side when the GTO is in off-state is suppressed. Accordingly, the controllable current of the GTO at that time is sharply increased and an excess short-circuit current can also be broken.

Title: Si dryetching process
Inventor: IGAWA EIJI
IPC: H01L21/3065
Filed: 1990-04-10
Abstract: PURPOSE:To perform Si etching process leaving no residue at all in anisotropical and vertically stepped parts at high selection ratio of oxidation resistant film etching process by a method wherein silicon nitride is used as a specimen side electrode while specific amount of H2 gas added to and mixed with SiBr or SiBr4 is used as etching gas. CONSTITUTION:An SiO2 film 2 is formed on an Si substrate further a stepped part 5000Angstrom  thick is formed on thic SiO2 film 2 and then polycrystal Si layer 3 2000Angstrom  thick is formed on the film 2 to perform phosphorus diffusion at 850 deg.C for 30min. Next, CVDSiO2 2000Angstrom  thick is deposited as SiO2 for mask which is etched away using CF4+CHF3 to form masks 5. Next, SiBr4 is fed at 40SCCM by a mask flow controller to be etched away at a pressure of 10 Pa and RF power of 550W. After the etching process, no residue can be observed in the region distant from the SiO2 by the deposited film thickness of the polycrystalline Si film 3. Furthermore, with hydrogen added, Br is exhausted since H reacts with Br in plasma turning into HBr, so that the Si deposited amount is increased while decelerating the etching rate thereby enabling the Si deposited amount on sidewall to be controlled.
