Title: Semiconductor device
Inventor: KUDOU OSAMU
IPC: H01L29/45
Filed: 1980-05-23
Abstract: PURPOSE:To prevent the generation of an alloy-spike by formig an amorphous silicon growth layer according to a plasma gaseous phase growth method between an aluminum metallic film and a semiconductor substrate. CONSTITUTION:An inactive region on a P type silicon substrate 101 is coated with a field oxide film 102, an N type impurity diffusion region 103 of 0.5mum junction depth is made up to an active region and the region 103 is coated with an insulating film 104. An opening 105 is built up, an amorphous silicon film 106 is coated by using a plasma gaseous phase growth method at a low temperature of 300 deg.C or less, and an aluminum wiring layer 107 is formed. The growth of the oxide film causing defective contact can be suppressed because the amorphous silicon film can grow at the low temperature. Since the amorphous silicon film is excellent in uniformity and is dense, it functions as a complete preventive film for an alloy-spike, and an integrated circuit having high reliability can be obtained.

Title: High voltage power circuit for ink jet recorder
Inventor: ISHIMA KAZUMI
IPC: G05F1/56
Filed: 1983-04-20
Abstract: PURPOSE:To obtain a simplified high voltage power circuit at a greatly reduced prime cost by operating the switching circuit of an ink jet recorder to be operated by a deflected high-pressure current through the switching circuit by the pulse output of the recorder. CONSTITUTION:A switching circuit 2 is operated by sending pulse drive signals having a fixed pulse width from the recorder as a pulse source. Also, DC power source of a boosting circuit 3 uses a power source having stabilized current of an operation amplifier, etc. When no pulse signal is present, the recorder is off and in case where printing is not made, there is no fear of electric shock and dust adsorption. Since the conventional pulse width control circuit and frequency control IC are not used, the circuit can be simplified and the prime cost can be greatly reduced.

Abstract: PROBLEM TO BE SOLVED: To make a contact opening/closing mechanism difficult for fatigue, damage or deformation caused by opening/closing to occur and enable replacement of parts by moving a driving member, rotating a columnar member by a ring-like member to rotate a cylindrical member around the columnar member and moving a contact member. SOLUTION: For opening/closing a contact opening/closing mechanism 19, a driving member 16 is moved while it is in contact with the slope of a columnar member 20 during its movement made between a first position for bringing it close to a columnar member 13 and a second position for moving it away from the same based on the existence of pressing applied to a pressing member 17. Two contacts are arranged to oppose each other, and an article to be inspected is held in a contact position therebetween. Also, after a specified process is carried out for the article to be inspected, movement is made away from the article to be inspected in the away position and thus the article is detached.

Title: Electrophotographic copying machine
Inventor: KUDOME YUTAKA
IPC: G03G21/06
Filed: 1982-04-23
Abstract: PURPOSE:To make a cleaning destaticization electrode unnecessary to make the device small-sized and economize in power, by impressing an AC voltage, which a DC voltage is superposed to, inclined to the positive to a separating electrode to give the retransfer preventing function when a transfer paper passes a separating electrode part and changing the value of DC voltage components to give the function as the cleaning destaticization electrode to the separating electrode when the transfer paper does not pass the separating electrode part. CONSTITUTION:In the time of the execution of an image forming process, the AC voltage of +5-6kV is impressed to a separating electrode for AC corona discharge, and DC voltage components of +0.5-2kV are superposed to incline the AC voltage to the positive for the purpose of preventing an image from being transferred to a photosensitive drum 1. In the time of the execution of other processes, no voltage is impressed to a charging electrode 2 and a transfer electrode 8. In this case, the same AC voltage as the conventional cleaning discharging electrode where DC voltage components are not superposed is impressed to the separating electrode 9. In processes other than the image forming process, the separating electrode 9 functions as the cleaning destaticization electrode, and the cleaning destaticization is performed in a high probability. Consequently, the defect of cleaning is not generated though the cleaning destaticization electrode does not exist.

Title: Pneumatic operator
Inventor: KASAMA YASUO
IPC: G06G5/00
Filed: 1980-05-27
Abstract: PURPOSE:To perform various operations with a high precision, by fitting a curve plate having a prescribed-form curve part to a flapper attachably and detachably freely and by allowing a feedback beam to contact with this curve part and by causing the flapper to adhere to a nozzle by the change of input and output pressure. CONSTITUTION:When input pressure is applied to an input bellows 11 as an input signal to increase its internal pressure, an input beam 10 is pressed through a driving material 11a and is turned counterclockwise around a spring part 10b. Then, a curve plate 20 is displaced in the direction of the (x) axis, and a curve part 20a is separated from a feedback beam 21. Consequently, the flapper 17 is turned by energizing force of a coil spring 19, and the gap between the flapper 17 and a nozzle 14 is narrowed to raise back pressure of the nozzle. This raised pressure is amplified by a relay valve 25 and is output; and when this pressure is applied to a feedback bellows 23, the beam 21 is turned clockwise and is displaced in the direction of the (y) axis and is allowed to contect with the curve part 20a again. Thus, the flapper 17 and the nozzle 14 are separated, and they are balanced at a point of time when they become the original state.
