Title: Semiconductor device
Inventor: TANIMOTO TAKUMA
IPC: H01L21/338
Filed: 1990-11-30
Abstract: PURPOSE:To acquire a semiconductor device having a hole movement layer of high efficiency by generating distortion by difference of lattice constant with a layer in contact with a substrate side and by making movement direction of carrier of a semiconductor layer using carrier conduction of the layer parallel with [100] direction of crystal. CONSTITUTION:A semiconductor device has a second semiconductor layer 5 which is in contact with a semiconductor substrate 1 or with a first semiconductor layer laminated on the substrate 1, and causes distortion in the second semiconductor layer 5 since lattice constant of the second semiconductor layer 5 is different from that of the substrate 1 or the first semiconductor layer wherewith it is in contact. In the semiconductor device which uses carrier conduction of the second semiconductor layer 5, movement direction of carrier of the second semiconductor layer 5 is made parallel to [100] direction of crystal. For example, an undoped InyGa1-yAs layer (y=0.2, 15nm) 5 is deposited on the semi- insulating GaAs (100) substrate 1 by MBE device and a specified semiconductor layer is formed thereon; thereafter, a source electrode 13, a drain electrode 14 and a gate electrode 15 are formed to make current flow in [100] direction.

Title: Elevator operation control device
Inventor: TERASAKI MASAYUKI
IPC: B66B1/14
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To operate an elevator safely even if the inside of a lifting path is flooded with water by heavy rain or flood, or flooding is expected. SOLUTION: In an elevator operation control device, a call registration switchover circuit 12 is connected between power lines A and B. Also a registration switchover switch 12a in the switchover circuit 12 is operated, for example, from a car 3 so as to operate a call registration switchover relay 12b and open its normally closed contact 12b1. By this, the operation of a call registration relay 1b on a corresponding lowest story is stopped, and the operation of a car to the lowest story is prohibited. As a result, the car 3 is avoided from dipping in the water flowed inside a pit of a lifting path, and an accident can be prevented from occurring. In addition, even if a switchover relay normally open contact 12b3 is operated by a remote operation, the same functional effect can be obtained.

Title: Sawtooth wave generation circuit
Inventor: WATABE HITOSHI
IPC: H03K4/08
Filed: 1997-12-09
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of noises from a constant voltage diode by providing on the power source-side of a switching element a constant voltage diode to determine the charging voltage of a capacitor. SOLUTION: In a sawtooth wave generation circuit, a constant voltage diode D1 to determine the charging voltage (reference upper limit voltage) of a capacitor C1 is inserted between the power source Vcc-side of a transistor (switching element) Q2 and the ground. Bias current is always supplied to the constant voltage diode D1 from a power source Vcc through a resistor R2 independent of on/off operation of the transistor Q2, so that the current value does not fall below a level where a noise is produced. Since a noise is not produced from the constant voltage diode D1, shaking in a vertical direction is eliminated.

Abstract: PURPOSE:To speed up a cycle by setting a gate at an upper end of a columnar rib having a reference rib at a lower position than an annular rib, keeping a heat source away and shortening a cooling period. CONSTITUTION:A valve pin 41 is descended to a position of a lower limit where a lower end of the pin is allowed to form a top surface of a columnar rib 35. A resin 24 is always melted by a heater 65 and a hot runner part 63. A movable mold 49 is brought close to a fixed mold 45 and further in tight contact with the latter thereby to close the molds. A forming cavity is defined by the fixed mold 45 and a gate bush 57. Then, the valve pin 41 is retreated and the resin 24 is injected from the gate 43 to the forming cavity. The flow of the molten resin is shut by lowering the valve pin 41 to the lower limit. The resin in the cavity is cooled by a cooling circuit. After a molded product is solidified enough, the movable mold 49 is moved to open the molds, whereby the molded product is released from the fixed mold and gate bush. Accordingly, a heat source is kept at a distance and a cycle is speeded up.
