Abstract: PURPOSE:To prevent crystal defect of crystal layer being caused to grow on the etching surface and improve reliability of element to be manufactured by etching a compound semiconductor crystal including aluminum (Al) using a mixed liquid selecting a volume ratio of sulfuric acid, hydrogen peroxide and water. CONSTITUTION:After causing a clad layer 12 including aluminum (Al), an active layer 13, a clad layer 14 and a current rejection layer 15 to grow on a substrate 11, the current rejection layer 15 is coated with a photo resist 16 and a striped window is formed to the resist 16.

Title: Waveform distortion equalizer
Inventor: MIYAZAKI TAKASHI
IPC: H04B10/2513
Filed: 1983-09-29
Abstract: PURPOSE:To attain equalization of waveform distortion at a reception end caused by spread of spectrum of a light source by branching a received optical signal in response to the wavelength, converting each of the branched optical signals into an electric signal, giving a different delay time to each of the signal converted into the electric signal and synthesizing and outputting the signals. CONSTITUTION:The optical signal inputted to an optical branching filter 6 via a lens 4 is branched into respective wavelength components lambda1, lambda2 and lambda3 and inputted respectively to Avalanche photodiodes 51-53, where the signals are converted into electric signals. Since the output of the Avalanche photodiodes 51- 53 and the output of the wavelengths lambda1-lambda3 correspond to the optical signal of the wavelengths lambda1-lambda3, the signal has a time difference respectively. Thus, the output of the Avalanche photodiodes 51-53 is eliminated for each time difference via delay circuits 71-73 to which a different delay time is set and the result is synthesized at a synthesis circuit 8. Since the delay time of the delay circuits 71-73 depends almost definitely on the length of an optical fiber 3 and the wavelengths lambda1-lambda3, the delay time is realized easily by changing the line length from the Avalanche photodiodes 51-53 to the synthesis circuit 8.

Inventor: ARAI TAKESHI
IPC: F03B3/18
Filed: 1988-07-20
Abstract: PURPOSE:To let the fluctuation in the threshold limit value of torque be made small, and thereby stabilize frictional performance by letting the surface finish of a guide vane be directed to a specified direction, and thereby letting the friction surface of a friction type torque transfer mechanism be of a specified finish. CONSTITUTION:The finish of the surface 12 of a guide vane which comes in contact with the friction surface 11 of a friction type torque transfer mechanism is determined to be directed to a specified direction. And the friction surface 11 of the friction type torque transfer mechanism is adapted to be non- directional in finish or to be widely different in the direction of finish from a specified one. By this constitution, the fluctuation in the threshold limit value of torque of the friction type torque transfer mechanism can thereby be made small, and frictional performance can be concurrently stabilized.

Title: Photoelectric converter
Inventor: SAKURAI YOSHIO
IPC: H04N5/335
Filed: 1980-12-22
Abstract: PURPOSE:To provide a flexible combination of the optical system and a sensor by inserting an optical fiber bundled in an array and an auxiliary optical system between an image forming surface of the optical system and a sensor for photoelectric convertion of the intensity of illumination in the radiation on the surface.

Patent JP-S6425065-A (JP)
Title: Sensor
Inventor: ONISHI HIROSHI
IPC: G01R19/165
Filed: 1987-07-21
Abstract: PURPOSE:To make it possible to provide a sensor characterized by low energy loss, by providing a substrate comprising a superconductive material and a member comprising a normal conductive material having the different thermal expansion coefficient. CONSTITUTION:A member 2 comprising a normal conductive material is mounted on the surface of a substrate 1 comprising a superconductive material, and a sensor 3 is constituted. When the substrate 1 is in the superconductive state, the resistivity of the substrate 1 is low and a current does not flow through the member 2. When the substrate 1 is changed into the normal conductive state from the superconductive state, the substrate 1 has a finite resistance value. A current begins to flow through the member 2, which is provided on the surface of the substrate. The substrate 1 and the member 2 start thermal expansion owing to Joule heat yielded at this time. Since the thermal expansion coefficient of the member 2 is different from that of the substrate 1, shearing force is yielded in the direction of the thickness of the substrate 1. Since the substrate 1 is brittle and cannot withstand the shearing force, the substrate is broken. The current path is cut, and the generation of an excessive current and the like can be detected. When the current flowing through the substrate 1 is within a rated value, the substrate 1 is in the superconductive state. Since the resistance value is small, energy loss due to Joule heat becomes very few.

Title: Insulated coil for electric apparatus
Inventor: TSUCHIYA MAKOTO
IPC: H02K15/10
Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To increase current capacity, by forming a bare flat electric wire at which one side surface is chamfered and the other side surface is not chamfered so as to be disposed in parallel in the row direction, bringing the respective surfaces which are not chamfered into contact with each other, conducting insulation and bending them on a plane surface in parallel to a disposing surface, and stacking them into a spiral form in the column direction. SOLUTION: When the thickness of an electric wire is 3 mm, a chamfering radius is approx. 0.8 mm. Therefore, the cross-sectional area of a conductor part becomes approx. 35.45 mm2. A bare flat electric wire 2b is disposed in two rows and one column in parallel, and an insulating film (polyester) tape is overlaid by half, wound six times and insulated to form the insulated flat electric wire 1. The bare flat electric wire 1 may be parallel-disposed in three rows or more and two columns or more. The number of winds of the insulating tape may be at least one. An insulated coil 5 is formed on the roughly parallel plane surface on which the bare straight angle electric wires 2a, 2b of the flat insulated electric wire 1 are disposed so as to be bent and stacked into a spiral form in the column direction.  Therefore, an air gap is not formed, thus it is possible to eliminate need for resin impregnation.

Title: Compressor driving device
Inventor: MATSUMOTO KIYOSHI
IPC: H02P1/44
Filed: 1987-07-22
Abstract: PURPOSE:To enable increase of starting torque and to permit improvement of running efficiency both during high load running and low load running, by providing a starting relay and a switch to change over two capacitors for a high and a low load. CONSTITUTION:Since, during the starting of a compressor 1, the voltage of a capacitor terminal is relatively low, a contact 5a of a starting relay 5 is motioned, capacitors 2 and 3 are connected in parallel to the auxiliary coil of the compressor 1 and therefore, starting torque is increased. Thus, even when load during the starting is high, the compressor 1 is started. Thereafter, when the number of revolutions of the compressor 1 is increased and the voltage of a capacitor terminal is increased, the contact 5a is disconnected, and the compressor is brought into a steady operation state. In this case, during coolant- heating heating operation in which a load on the compressor 1 is low, a capacitor 2 for a low load is used for operation. During cooling operation in which a load is high, with a change-over switch 4 changed over, a capacitor 3 for a high load is used for operation. This constitution enables drive of the compressor with high starting torque and besides with high operation efficiency.
