Title: Electrode connecting method
Inventor: SUNAMI HIDEO
IPC: H01L21/768
Filed: 1982-05-21
Abstract: PURPOSE:To perform electrode connection of high reliability with small junction leakage currents by a method wherein a protection film is adhered in the periphery of the internal wall of a through hole formed on an insulation film. CONSTITUTION:After a field oxide film 2 and a diffused layer 3 are provided on a semiconductor substrate 1, a layer insulation film 4 such as a PSG is adhered. Next, the end part protection film 9 is adhered over the entire surface, after the insulation film 4 is etched thus a contact hole 10 which reaches the diffused layer 3 is formed. For this protection film 9, an insulation film such as SiO2 or Si3N4, and a film of difficultly fusable metal such as polycrystalline Si, Mo, or W, or the silicide film thereof, etc. can be used. Then, an end part protection film 9-1 is left on the side surface of the internal wall of the contact hole 10 by self-alignment by etching the entire surface of the protection film 9 uniformly. Thereafter, the electrode 8 of Al, etc. is formed. If the protection film 9 is polycrystalline Si, etc., an additional diffused layer 11 can be formed by a method of adding an impurity to the protection film 9, etc.

Abstract: PROBLEM TO BE SOLVED: To reduce the power loss in a zero voltage circuit, by controlling the initial current to a reactor for resonance according to the output current detected by a detecting means. SOLUTION: A power converter 10 is composed of an inverter circuit 3 for converting DC power into AC power synchronous with a system power supply, a zero voltage circuit 2 for turning the input voltage to zero voltage at the time of switching, a controller 11 for controlling the zero voltage circuit 2 and the inverter circuit 3 through a first and a second drivers 7, 8, and a current sensor 12 for detecting the output current of the inverter circuit 3.

Title: Pedal operating device of sewing machine
Inventor: GONDA YOSHINORI
IPC: D05B69/18
Filed: 1990-03-30
Abstract: PURPOSE:To reduce only initial pedal pressure while giving proper pedal pressure nearly over the whole region in forward pedalling to facilitate speed adjustment in one needle or low speed sewing by operating a second spring later than a first spring in the forward pedalling of a foot pedal and operating the first spring later than the second spring in the backward pedalling. CONSTITUTION:A second spring 17 acts after a first spring 14 acts first in forward pedalling, and the first spring 14 acts after the second spring 17 acts in backward pedalling. By such action of two springs both in the forward and backward pedalling, three springs so far needed are replaced by two springs so that the number of parts of a pedalling device can be reduced to simplify substantially the construction. Since conventionally one spring was used in the forward pedalling, reduction of only initial pedal pressure could not be achieved. By operating the two springs in different operating times, however, proper pedal pressure is given nearly over the whole region while only the initial pedal pressure can be reduced so that speed adjustment can be remarkably easily carried out in one needle and low speed sewing.

Abstract: PURPOSE:To send a normal driving signal to an actuator even in case of troubles of a CPU by sending a stop signal to a square wave oscillator provided in a control unit when the CPU is normal but not sending the stop signal there when the CPU is abnormal. CONSTITUTION:When a CPU 2 is operated normally, the stop signal inputted from an output terminal P1 to the inverted input terminal of an operational amplifier 10 of a square wave oscillator 3 through a stop signal line 6 is not oscillated at all at a point B of a reset signal line 7, and a certain voltage acts upon a reset signal terminal R.

Abstract: PURPOSE:To prevent a belt from its exfoliation due to lifting in the time of running by spirally winding an organic fiber cord continuously in the peripheral direction on the peripheral surface of the belt in a manner, wherein the cord forms its pitch closer in a shoulder part of the belt, and forming a belt reinforcing layer. CONSTITUTION:A tire forms its belt reinforcing layer by an organic fiber cord, and the cord is formed, for instance, applying a rubber coating 2 to a single streak of long-sized cord 1. This cord 1 is spirally wound continuously in the peripheral direction, for instance, only on both shoulder parts BS in the peripheral surface of a belt 4 wound on a belt drum 5 or the like. By the constitution thus obtained, the belt reinforcing layer serving as the edge band is formed. Here the cord 1 sets its winding pitch 1 to within a range of 0.5-5.0mm for preventing lifting in both the shoulder parts BS of the belt 4. In this way, decreasing a difference of stretch between both the shoulder parts BS of the belt 4 and its central part, thermal contracting force is improved in both the shoulder parts BS.
