Title: Optical coupling semiconductor device
Inventor: IITAKA YUKIO
IPC: H03K17/687
Filed: 1985-07-25
Abstract: PURPOSE:To obtain an optical coupling semiconductor device conducted when no optical input signal exists and not conducted when the signal exists by inserting a circuit composing of photodiodes 1 connected in series and a resistor between the gate and source of a normally-on type field effect transistor (TR). CONSTITUTION:The circuit composing of the photodiode 1 connected in series and a resistor 3 is inserted between the gate and source of the normally-on type field effect TR FET 2. When an optical input signal exists from a LED 6, the FET 2 is in the conductive state. A current through the FET 2 is taken as a base current of an output TR 4, and the TR 4 is conductive when no input signal exists. When the optical input signal exists from the LED 6 and a potential difference is caused between the gate and source of the FET 2, the FET 2 is conductive. The base current to the TR 4 is zero and the TR 4 is nonconductive.

Title: Vibration damping equipment
Inventor: WATANABE ISAO
IPC: B60G13/08
Filed: 1990-06-26
Abstract: PURPOSE:To simplify and miniaturize the structure of a vibration damping equipment by enclosing a gas or a fluid, which can be liquidized, in a sealed room and setting installing members on both a contracted-passage-constituting- member-side and a face-plate-side of the equipment, thereby effectively absorbing high frequency microvibration. CONSTITUTION:One sealed room 6 is formed in such a manner that folding parts 1a, 2a of both flexible film bodies 1, 2 face to each other. Inside this sealed room 6, both face plates 4, 5 of the room 6 are connected to each other by means of a cylindrical rigid member 7. In the sealed room 6, air or other gas or water, an antifreezing solution, an electroviscous fluid, a magnetic fluid and a fluid 8, which can be liquidized are enclosed. In addition, installing members 11, 12 are set on the face plate 4 and on a contracted-passage- constituting-member 3. Owing to a sliding guide 13, sliding motion of a rigid member 7 is smoothed, and moreover it is unnecessary to consider the sealing property to the enclosed fluid 8. Therefore, frictional force of the rigid member 7 to the sliding guide 13 can sufficiently be made small.

Abstract: PURPOSE: To efficiently test a plurality of batteries for discharge without interruption and without letting any of the batteries overdischarge, by setting a reference voltage to a suitable anti-overdischarge voltage.  
     CONSTITUTION: When a battery E 1  discharges and gradually decreases in voltage to attain an overdischarge voltage, an output from a comparison amplifier CMP 1  is turned to a lower level to allow a transistor Q 1 , which forms a change-over circuit in the following stage, to be turned on, and to allow an electric current to flow to a set coil a on an unreset relay RL 1 . As a result, the battery E 1  is separated from the discharge circuit to be put into a no-load state. An input into a conversion circuit is short-circuited by a change-over switch l 1 . An output from the comparison amplifier CMP 1  attains a high level again so that discharge test for the remaining batteries is carried out continuously without interruption.

Title: Process for inhibiting generation of and removing scale using water brought into contact with ceramic sintered compact
Inventor: DOYAMA MASAO
IPC: C02F1/00
Filed: 1998-05-11
Abstract: PROBLEM TO BE SOLVED: To prevent fuel or power wastes causing global warming by suppressing generation and deposition of scales and removing these through a process which has no risk of environmental pollution usually caused by chemical drug treatments. SOLUTION: A compact, obtained by sintering ceramics comprising natural stones mainly comprising silica and alumina through a special method, is brought into contact with water to impart water solubility to a portion of various kinds of scales to inhibit generation and deposition thereof, remove them and optionally remove malodor caused by deposited scales. Water which is brought into contact with this ceramic sintered compact has an ability to reduce the major portion or a portion of scales, which had been oxidized in the atmosphere and had become water-insoluble or difficultly soluble to water, to make them water-soluble again. Therefore, stuck scales which have just generated are immediately dissolved in water to inhibit their deposition.

Title: Signal processor
Inventor: HASHIRANO MASARU
IPC: H04N5/93
Filed: 1988-07-04
Abstract: PURPOSE:To evade head switching at a position where a synchronizing signal is superposed even though there is the omission of the synchronizing signal by latching a head switch signal by generating the clock of frequency approximately twice as large as a horizontal synchronizing signal by an oscillating means being locked at a regenerative synchronizing signal. CONSTITUTION:In a VTR, the oscillating means 9 to which the synchronizing signal S1 extracted from a regenerated video signal is supplied is locked at the signal S1, and outputs the clock S8 of the frequency approximately twice as large as the horizontal synchronizing signal, and controls a normalizing means 7. Then, the head switching signal is latched by the means 7, and is normalized and outputted. By using this clock of the large frequency, even if the omission of the synchronizing signal due to drop-out, etc., occurs, only locking motion is not performed at that point of time, and oscillation output is not influenced by it, and the head switching at the position where the synchronizing signal is superposed can be evaded, and the synchronizing signal of the head switched regenerative video signal goes to stable one less influenced by noise.
