Title: Method for lowering earthing resistance of power transmission steel tower leg
Inventor: TAMURA SHIGEHISA
IPC: H01R43/00
Filed: 1990-07-17
Abstract: PURPOSE:To lower the rise of electric potential due to a steel tower earthing resistor at the time of lightning by altering the resistance of a buried conductor according to the measured earthing resistance of each tower leg of an power transmission steel tower. CONSTITUTION:Earthing resistance Ra, Rb, Rc, Rd of four tower legs 1a, 1b, 1c, 1d of a power transmission steel tower are either measured by measuring for each of the legs 1a-1b by an earthing resistance measuring apparatus or calculated by measuring practical divided current of lightning current for each of the legs 1a-1d. Then, according to each measured resistance, each length La, Lb, Lc, Ld for each of buried linear conductors 2a, 2b, 2c, 2d which are connected with the legs 1a-1d each and buried in ground horizontally is so determined as to make the earthing resistance Ra-Rd of each tower leg 1a-1d become almost equal and the compound resistance of the earthing resistance Ra-Rd of each tower leg 1a-1d be within a standard compound resistance of four legs. As a result, the earthing resistance of each of the tower legs is made almost equal each other and the rise of electric potential due to the leg earthing resistors at the time of lightning is lowered and accidents by lightning is prevented.

Inventor: KOMIYA TAKEHARU
IPC: C03B11/08
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To obtain a forming mold for an optical element which does not cause roughening of the forming surface or deposition of glass to be formed on the mold even when the mold is repeatedly subjected to heating and forming, by forming a surface layer of a thin film comprising a specified ternary alloy on the forming surface of a substrate comprising tungsten carbide.

Abstract: PURPOSE:To control pump input accurately and stably by feed forward controlling input horse power in response to discharge pressure while feed back controlling input horse power in response to the rotational frequency of a prime mover. CONSTITUTION:Discharge pressure Pd1, Pd2 of one pump is conducted to spools 6,8 of regulators 5, 7, and discharge pressure Pd2, Pd1 of mating pump conducted to stepped pistons 39, 40 so that input horse power of precontrolled hydraulic pumps 2, 4 is balanced with the output of a prime mover 20 by this feed forward function to determine the actual rotational frequency Ne of a prime mover 20.

Title: Fan
Inventor: SUGAWARA NORIO
IPC: F04D17/04
Filed: 1981-11-20
Abstract: PURPOSE:To make it possible to sharply reduce decline of flow capacity in such a way that while flow can be deflected from practically horizontal down to directly below by just rotation of one shaft, distributary condition is made ready, and deflection is achieved by utilizing nature of fluid itself. CONSTITUTION:While optional flow can be oriented from practically horizontal direction to downward direction by just rotation of a flow control member 10, distributary movement can be effected as well. And since a flow control member 10 is purposed for that while ratio of upward and downward flow passing by the flow control member 10 is changed, deflection is effected by utilizing adsorptive effect to a rear guider 9, decline of the flow capacity can be minimized. As shown in the figure, in the event that it is applied to a wall-hanging heat pump, favorable air conditioning can be obtained almost without lowering the flow capacity by actuating a lever 15 to arrange the flow in horizontal direction for cooling phase, and in downward drection for heating phase and thus  switching when it is at air cooling, to the distributary.

Title: Constant vacuum type carburetor
Inventor: TSUTSUI KATSUHIKO
IPC: F02M7/17
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To suppress the lowering of intake efficiency and excessive concentration in air-fuel mixture concentration by disposing a collision buffering member formed out of a material of low hardness at a contact part between a cover and a negative pressure operation valve at the time of the maximum opening of the negative pressure operation valve. SOLUTION: A negative pressure operation valve guiding cylinder 3 is formed continuously at an intake passage 2 which penetrates a carburetor body 1. A negative pressure operation valve 6 which conducts variable control of the area of a venturi part V is disposed at the negative pressure operational valve guiding cylinder 3 so as to move freely. The valve part 6A, the retainer 6D, and the cover 8 of the negative pressure operation valve 6 are formed by synthetic resin material which contains glass fiber. A collision buffering member 10 is disposed at a contact part between the upper part of the negative pressure operation valve 6, and the bottom part of the cover 8 facing it, at the time of the maximum opening where the negative pressure operation valve 6 keeps the intake passage 2 in a fully opened condition.  The collision buffering member 10 is formed out of a material of lower hardness than the synthetic resin material which forms the negative pressure operation valve 6 and the cover 8. It is thus possible to suppress the lowering of intake efficiency, and excessive concentration phenomenon in air-fuel mixture.

Title: Spot killer circuit for cathode ray tube
Inventor: KAWAMURA KEIICHI
IPC: H04N3/20
Filed: 1987-07-29
Abstract: PURPOSE:To properly and simply prevent the spot of electronic beams by providing a switching circuit, which changes the partial pressure ratio of a partial pressure circuit in accordance with the impression of a signal to indicate the cutoff of an alternating voltage source, so that the electronic beams may not be emitted from the cathode of the titled cathode ray tube at the time of the cutoff of the alternating voltage source. CONSTITUTION:Since a capacitor C1 is charged during the action of a CTR, for example, when the power source of the CRT is turned off, the capacitor is discharged at a required time constant. For that reason, a voltage V1 can be held at a negative voltage for the required time, and a transistor TR2 goes to a turn-on condition. As this result, the collector current of the TR2 increases, a base voltage V3 of a TR1 for feedback increases in a ground direction. Thus, a first grid G1 can be held at a cutoff voltage or below for the required time, the electronic beams to move due to the residual capacity of an anode are cut off, and the generation of the spot can be prevented.

IPC: G11B7/24082
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To easily identify that a reproduced data stream is an illegal copy even when the reproduced data stream is copied with a bit stream by frequency- modulating a reference clock for forming pits and lands at the time of manufacturing with a sub-data of a specified frequency consisting of the text data showing copyright of a file. SOLUTION: An EFM circuit 14 sends a modulation signal S1 modulating a bit stream consisting of main data to be recorded with a frequency modulation clock CKF to an optical modulator 8. The optical modulator 8 turns a laser beam L on/off with the modulation signal S1 and exposes a master disk 2 to form a pit and land. Sub-data D2 are set so that the distribution of the side band of the frequency modulation clock CKF is 1 kHz or below from a central frequency, and doesn't become 10 Hz or below. In a regular spindle motor servo having inertia, it is difficult to follow fluctuations in high frequency of a regenerative clock.

Title: Removal method of resist film
Inventor: IWAMATSU SEIICHI
IPC: H01L21/30
Filed: 1990-07-17
Abstract: PURPOSE:To completely remove even an ion-implanted photoresist film by a method wherein an oxygen plasma, ions, a resist removal gas such as ozone gas or the like is impinged on a resist-coated face in a small-angle direction. CONSTITUTION:An oxygen plasma provided with directivity is impinged on a photoresist film which has been coated on the surface of a semiconductor substrate, whose exposure and development have been processed and into which ions have been implanted in such a way that it is inclined at a small angle (1 to 10 deg.) to its coating face; the substrate is turned. Then, an etching operation progresses preferentially from the interface of a bonded part between the resist film and its substratum; the resist film is etched from the surface, the rear and the side face. In this case, a thin film of the resist film whose polymerization has progressed after completion of the etching operation at the interface is stripped. The stripped film is dropped as it is and is captured. Alternately, counter electrodes or the like are installed and the film is removed and captured electrostatically. Thereby, the resist film is not left on the surface of the substrate and can be removed completely.
