Title: Small reduction gear
Inventor: KINOSHITA SATOSHI
IPC: F16H1/28
Filed: 1989-02-13
Abstract: PURPOSE:To provide a small reduction gear which is decreased in size and weight and has a high reduction ratio, a low backlash, and high transmission efficiency by a method wherein the gear at each stage of the planetary gear, having 2-stage structure, of a planetary gear mechanism is formed with a tooth shape in an iso-phase having the same number of teeth and a slightly different module. CONSTITUTION:A tooth shape part a13 of a planetary gear and a tooth shape b14 of a planetary gear are ZT having the same number of teeth as each other, and have slightly different modules from each other and the phases of tooth shape being equal to each other. With a solar gear 4 rotated, a planetary gear 12 starts rotation and revolutions since a stationary internal gear 10 is not moved. In which case, the number of teeth of the stationary internal gear 10 is (n), and the number of teeth of a moving internal gear 20 is n+ or -1-4. Thereby, rotation and revolution of the planetary geer 12 cause displacement of the tooth shape part of the stationary internal gear 10 from that of the moving internal gear 20. As a result, the moving internal gear 20 performs decelerated rotation. This constitution transmits decelerated rotation and increased torque to the moving internal gear 20 through rotation of the solar gear 4 to output it to an output shaft part 22.

Title: Base material for electromagnetic wave shielding
Inventor: INOUE KUNIHIRO
IPC: B32B9/00
Filed: 1988-02-16
Abstract: PURPOSE:To make even a resin material with a low melting point to have a sufficient adhesion, by a structure wherein an oxide is made to adhere to a resin of a base material, and subsequently a shielding metal is deposited thereto. CONSTITUTION:An oxide layer 3 is formed on a resin 4 of a base material and a shielding metal is then deposited on the oxide layer 3. That, is in order to combine a shielding and an anti-corrosion, a nickel 1 is deposited on a copper 2 to form the shielding metal. When the shielding metal consisting of the nickel 1 and the copper 2 is to be deposited to the resin 4 of a base material by means of vacuum evaporation, the oxide layer 3 is previously formed on the resin 4, and thereafter the shielding metal is deposited. Thereby, in the interface between the resin and the oxide, carbon components of the resin and oxygen components of the oxide are chemically bonded each other to increase a bonding strength therebetween, while in the interface between the oxide and the metal, the oxygen components of the oxide is chemically bonded to the shielding metal to increase a bonding strength therebetween. Since there is a large bonding strength in each the interface, in the vacuum evaporation process, a good adhesion is obtained without the base being specially heated. As a result, a base material for electromagnetic wave shielding can be produced even though the resin of the base material has a low melting point.

IPC: H01L21/82
Filed: 1991-02-28
Abstract: PURPOSE:To prevent the occurrence of a design error of the erroneous deletion and the deletion forgetting of a segment to occur when a wiring channel is changed by deleting automatically an unnecessary segment when the segment is added. CONSTITUTION:For example, when the wiring channel is changed so that the wiring between pins 23 and 25 can be performed, at first, a segment 32 is added. Since both edge points of the segment 32 are investigated and plural segments are not connected, a segment 27 is not stored. Next, a segment 33 is added. Since two segments of a segment 31 and a segment 30 are connected to one side edge point of the segment 33, segments 30 and 31 are stored. Since other segment is not connected to one side edge point of the segment 31, the object of trace processing is not obtained for the segment 31. The trace processing is performed to the segment 30, and continuously, the trace processing is performed to a segment 29. Since the edge point to connect the segment 29 and the segment 27 is a branching point, segments 30 and 29 up to the branching point are deleted. When the edge point connected to the next segment is the pin, the segment up to it is deleted.

Filed: 1991-02-28
Abstract: PURPOSE: To simplify a circuit constitution by selectively switching outputs of amplifiers of a front stage while using switches in a midway and amplifying the outputs with amplifiers of a poststage while performing a two-stage amplification at the time of a reproduction to reduce the number of amplifiers. CONSTITUTION: A recording amplifier part 70a amplifies signals to be outputted from a recording equalizer 50. Then, in a state in which signals outputted from the amplifier part 70a are recorded on a tape through heads 80a-80e fixed to a drum and they are detected through the heads 80a-80e, a reproducing first amplifier part 100a respectively amplifies the output current signals. A switching part 100b switches signals transmitted from the amplifier part 100a. A reproducing second amplifier part 100c amplifies output signals of the amplifier part 100a selectively switched in the switching part 100b again to transmit them to a reproducing equalizer 110 being in an output part. By this constitution, amplifiers or the like are reduced in roughly half by using switches in the midway while performing the two-stage amplification at the time of the reproduction.

Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To realize a secure output by an input means in a simple structure, even when the fluid pressure is lost, as well as to set the stroke of the input means in an extreme short stroke. SOLUTION: Solenoid switch valves 46 and 48 are closed by depressing a brake pedal 2, in the normal condition of a pressure source 30, while a master cylinder(MCY) 3 generates an MCY pressure by depressing the brake pedal, and pressure control valves 7 and 8 generate a motive pressure responding to the pedal depressing force by the MCY pressure. The motive pressure is led in to the motive power chamber 41 of an actuator 11, the actuator 11 generates a brake liquid pressure, and wheel cylinders(WCY) 15 and 16; 17 and 18 operate a normal brake by leading in the brake liquid pressure. Since the solenoid switch valves 46 and 48 are opened in the losing condition of the pressure source 30, the MCY pressured generated by depressing the brake pedal is led in to the WCYs 15 and 16; 17 and 18, and the brake is operated even in the losing time of the pressure source 30. The stroke of the brake pedal 2 is made shorter, because it is made as the operating part of the valve plugs of the pressure control valves 7 and 8.
