Title: Lap resistance welding machine
Inventor: TASHIRO TOMOO
IPC: B23K11/24
Filed: 1983-03-14
Abstract: PURPOSE:To eliminate thoroughly the loss time in a squeezing time by conducting slight current within the squeezing time, detecting the change in a current value owing to a decrease or increase in the contact resistance in the stage of pressing the electrodes and reading the timing in the conduction of the welding current. CONSTITUTION:Slight current is conducted from an auxiliary power source 11 within the squeezing time when the works 7 are clamped between electrode chips 5 and 6 by the operation of a pressing cylinder 4, then the decrease in the contact resistance with an increase in the pressing force is measured by a current detector 12 by a change in the value of the current flowing to the primary or secondary side of a welding transformer 3. The reference current value when the electrodes attain a substantial pressure is set in a setter 14 and a signal for conducting the welding current is outputted to a sequence timer 9 from a comparator 13 when the detected current values exceeds the set value. The loss time within the squeezing time in the sequence control is thus thoroughly eliminated.

Title: Thin film photoelectric transfer device and manufacture thereof
Inventor: HAMA TOSHIO
IPC: H01L31/04
Filed: 1991-03-08
Abstract: PURPOSE:To resolve such problems which need for a cover glass when a transparent electrode is placed on the top layer and produced in a modular structure and causes thermal damage on the lower layer due to the temperature during the film formation of a CuInSe2 when a transparent electrode layer, an n-type CdS layer, and a p-type CuInSe2 layer are laminated on a transparent substrate. CONSTITUTION:An n-type a-SiC layer is formed on a transparent electrode layer comprising ZnO on a transparent substrate and a p-type CuInSe2 layer is laminated thereon. The ZnO and a-SiC layer have heat resistant properties against the temperature of 400 deg.C produced when a CuIn alloy is turned into selenium. These properties prevent the thermal damage. It is possible to form an a-SiC film having a wider 2.05eV optical gap than a 1.04eV optical gap of CuInSe2, if a mixed gas of SiH4 and CH4 at the ratio of 3:7 is used.

Title: Liquid crystal display substrate
Inventor: HIROSHIMA MINORU
IPC: G02F1/1368
Filed: 1993-03-03
Abstract: PURPOSE:To prevent the seizure in image display by setting the protective film formed on electrodes provided on a liquid crystal display substrate surface on the side in contact with a liquid crystal at a specific range. CONSTITUTION:A thin-film transistor TFT and a transparent pixel electrode ITO1 are provided thereon with the protective film PSV1. The protective film PSV1 is formed mainly to protect the TFT against moisture and a film having good moisture resistance is used. The protective film PSV1 consists of an org. resin film and is formed by spin coating or printing.

The protective film has a middle insulating characteristic. The protective film PSV1 has the middle insulating characteristic like this and, therefore, even if charges remain in this insulating film, the remaining time thereof is shortened.

Filed: 1989-02-27
Abstract: PURPOSE:To isolate the vibration efficiently by providing a phase control circuit for reversing the phase of the generated vibration caused by the expansion of a piezoelectric actuator against a phase of the acceleration or the vibration of a vibration transmission lute detected by a displacement sensor, and adding the phase control circuit to the vibration transmission lute. CONSTITUTION:Though an acceleration sensor 14 detects the vibration of a vibration transmission lute, since the whole vibration transmitted from an engine is detected, only the vibration in the frequency area to be a subject of the vibration isolation is taken out by a band path filter 15. Next, the vibration is jacked up and modulated to the positive side by a compressor 17 showed in a waveform 18. Te phase of the waveform 12 is reversed by a phase shifter 19 showed in a waveform 20, and the waveform 20 is amplified by a power amplifier 21 so as to be the input voltage with which the required expansion quantity of a piezoelectric actuator 5 is obtained, and is applied to the actuator 5. Since the vibration by the engine rotation secondary element and the vibrative force decided by the applied voltage are opposite each other, they are perfectly denied each other to isolate the vibration.

The resin produces the effect when added by 5-100mg per 1g silver nitrate in consideration of other constituent elements. The silver halide emulsion used may contain not only singly dispersed particles but also particles not dispersed singly, but it is preferable that the emulsion contains only singly dispersed particles. The crystal habit of the silver halide is not especially limited. The particle size of the silver halide emulsion is not especially restricted but is usually 0.05-1mum. The silver halide emulsion contg. the resin is applied to a proper support such as coated paper.

Abstract: PURPOSE:To shorten the storing time of a main switching semiconductor element by connecting a reverse bias semiconductor element in series with a coil added to a main transformer and conducting the drive switching semiconductor element. CONSTITUTION:When a main transistor 1 is interrupted, a transistor 24 is interrupted, a transistor 25 is conducted, and a current flowing through a resistor 20 is flowed through the transistor 25. Accordingly, a reverse bias transistor 15 is interrupted. Thus, even if the waveform of the main transformer 7 is thereafter vibrated, a reverse bias transistor 15 is interrupted until the drive transistor 2 is conducted. In this manner, the input coil n1 of the drive transformer 3 is not excessively excited through the transistor 16 from the coil N3 of the main transformer 7 but instead is stably operated.
