Title: Opening and closing control device for elevator door
Inventor: TAWADA MASANORI
IPC: B66B13/26
Filed: 1993-04-02
Abstract: PURPOSE:To suppress an amount of movement of a door in a closing direction when a reversing direction is outputted during closing operation of the door of an elevator, to ensure safety, and to suppress the generation of a device shock. CONSTITUTION:When a door is driven with the aid of a motor 5, a pulse responding to a rotation speed is generated from a pulse encoder 6. A CPU 9 is operated to compute the position point of a door from a pulse count value and read a speed command value, matching with the door position point, from an ROM 10 to control a gate signal generating circuit 15. When a reversing demand is outputted from a reversing demand safety device 2, a current speed command value is detected. In a case of a high speed, inclination of a deceleration command value is increased according to the detected value and in a case of a low speed, it is decreased.

Title: Manufacture of laser diode
Inventor: SHIGE NORIYUKI
IPC: H01S5/223
Filed: 1981-05-22
Abstract: PURPOSE:To manufacture the concave part of an N-type clad layer of laser diode just upon a V-shaped groove having favorable reproducibility by a method wherein the main face of substrate is formed in the face having the inclination in relation to the (110) crystal face in the <110> crystal direction. CONSTITUTION:The GaAs substrate 2 having the V-shaped groove 1 at the center of main face is prepared. The V-shaped groove 1 trereof is provided along the <110> direction, while the main face 11 of the substrate 2 has the inclination alpha between the (100) crystal face 12. The inclination alpha thereof is made as larger than unevenness of the flatening work of the main face. As a result, alpha is always larger than the inclination beta of the main face 11 in relation to the direction of plane making a right angle with the V-shaped groove 1. Accordingly when the N-type clad layer 3 consisting of GaAlAs is formed on the main face 11 of the substrate 2 using the substrate 2, the concave part 5 of the layer 3 trereof can be formed just upon the V-shaped groove 1 of the substrate 2 having favorable reproducibility. When an active layer of GaAs is formed thereon to form the laser diode, the light emitting part is made as the active layer part corresponding to the concave part 5, and the mode of laser beam is stabilized.

Title: Gain control circuit
Inventor: SUGAWARA MITSUTOSHI
IPC: H03G3/10
Filed: 1982-05-07
Abstract: PURPOSE:To suppress dererioration in the unbalance and nonlinearity of a double balanced circuit, by supplying a current to the circuit through transistors (TR) applied with a constant bias voltage. CONSTITUTION:The input signal from a signal source 11 is amplified by a TR1  and supplied to the emitters of TRs 3 and 4. Since the TRs 3 and 4 are controlled by a gain control voltage 25, the output signal of the TR1 is distributed  to the TRs3 and 4 in accordance with the control, and then outputted through a  TR8. A load resistance 26 develops a voltage which is constant in terms of  direct current. This DC voltage is applied to the base of the TR8 to hold the  base emitter voltages of the TRs 7 and 8 constant. Therefore, the collector  emitter voltages of the TRs 3-6 all become equal to obtain a high degree of  balancing.

Abstract: PURPOSE:To decrease leak current down to a negligible level and to improve display image grade by shutting off the photoirradiation to a semiconductor film by a metallic film. CONSTITUTION:After a conductive film 30 is formed by a sputtering method, a photosensitive resin is coated thereon and is subjected to exposing and developing by using a mask to form a 3rd photoresist 22.

Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To obtain a high contrast ratio and steep threshold value characteristics at a relatively low pretilt angle without decreasing light utilization efficiency by using a specific dielectric mirror. SOLUTION: This element is equipped with a photoconductive layer 10 which varies in impedance by being irradiated with light, a liquid crystal layer 11 which is arranged nearby the photoconductive layer in parallel, and the dielectric mirror 12 which is formed between the liquid crystal layer 11 and photoconductive layer 11 and reflects readout light 31 having passed through the liquid crystal layer 11. The dielectric mirror 12 in use has optical anisotropy, its optical axis almost orthogonally to that of the liquid crystal layer 11 when a specific voltage is applied, and retardation nearly equal to that of the liquid crystal layer 11 when the specific voltage is applied. Consequently, when the specific voltage is applied to the liquid crystal layer 11, the retardation caused when light passes through the liquid crystal layer 11 is compensated by this dielectric mirror 12, so the light is prevented from being polarized elliptically almost at the threshold voltage to leak out of the liquid crystal layer 11.
