Title: V-belt type stepless speed change gear
Inventor: SAKAKIBARA SHIROU
IPC: F16H61/26
Filed: 1982-11-27
Abstract: PURPOSE:To improve durability of a pulley and a V-belt and to improve power transmission efficiency by precisely increasing and decreasing the clamping force between the pulley and the V-belt in proportion to the transmission torque. CONSTITUTION:In case of up-shift, brakes 63, 73 are engaged, and sleeves 62, 72 are rotated relatively to sleeves 38, 47 of movable flanges. The movable flange 3B is displaced in direction of increasing the effective diameter, and the movable flange 4B is displaced in direction of decreasing the effective diameter to reduce the reduction gear ratio. At a setpoint, the brakes 63, 73 are released. In case of down-shift, a brake 66 is engaged to fix a sun gear 64S, and the sleeve 62 is rotated at an increasing speed by a ring gear 64R to displace the movable flange 3B in direction of decreasing the effective diameter. At a setpoint, the brake 66 is released. Thus, when a servo mechanism of the movable flange goes wrong, the speed change ratio is fixed to heighten safety.

Title: Power source switching control circuit for plural motors
Inventor: SHIMIZU HIROKI
IPC: H02P5/74
Filed: 1982-11-26
Abstract: PURPOSE:To effectively protect a motor without flowing an overcurrent to the motor by automatically deciding the current limiting value flowed out from an inverter in response to the number of the motors. CONSTITUTION:When a signal is applied to a motor number detector 20, the output of an adder 21 becomes a value corresponding to the sum of the motors which are driven by an inverter. Further, the output of the adder 22 is applied with a bias 23, and becomes an input of a limiter 24. The limiter 24 limits the maximum value of a proportional amplifier 16 in response to the input signal. In other words, a load current has no margin to exceed the current limiting value Ip. In this manner, two motors are stabilized in the same rotating speed while the load current is limited to the current limiting value Ip.

Abstract: PURPOSE:To enable the surface of semiconductor to be cleaned up with excellent reproducibility by a method wherein gas plasma of hydrogen compound of V group element contained in the semiconductor is brought into contact with the surface to be cleaned. CONSTITUTION:Within an electron-cyclotron plasma producer, a divergence magnetic field is generated to carry plasma to a surface cleaning chamber 4 with extremely low accelerating energy (around -15eV) colliding with the surface of a semiconductor 5 inserted into the chamber 4 at moderately low speed so that a surface denatured layer may be removed efficiently by the actions compounded of the high etching and reducing capacities of hydrogen ion and hydrogen radical and the moderate physical shock. Simultaneously ion radicals of arsenic and phosphorus are compounded of oxygen, hydrogen and water to produce an arsenide and a phosphide. Finally the arsenide and the phosphide are coevaporated to be discharged out of the surface cleaning chamber 4 not sticking on the surface of semiconductor with surface denatured layer removed. Through these procedures, the surface of semiconductor can be cleaned up with excellent reproducibility.

Abstract: PURPOSE:To obtain a switch gear having the high reliability, and to simplify the inside of a switch gear by providing a voltage detecting relay by separating it from the switch gear, between the neutral point of the bus of the switch gear and the load side of each phase of a semiconductor element switch, and comparing a voltage detecting signal with the control signal of the semiconductor element switch. CONSTITUTION:A neutral point voltage is generated by a resistor 10 connected to a bus, and a voltage detecting relay 11 is inserted between its neutral point and each phase of the load side of the semiconductor element switch 4. At a normal time, the switch 4 conducts by a turn-on command, and the relays 11 of each phase are also excited. In this case, if there is an element which does not conduct, in three elements of the switch 4, the relay 11 of its phase is not excited, and a faulty element is detected. Subsequently, in case of drawing out, at a normal time, the relays 11 are not excited at all. If there is an element which remains conducting, the relay 11 of its phase remains excited, therefore, a faulty element can be detected. Also, by separating a switch gear and a test panel, the inside of the switch gear can be simplified.
