Title: Reflection type liquid crystal display device and its manufacture
Inventor: KAGAWA YUUICHI
IPC: G02F1/1368
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To make it possible to detect a pixel defect. SOLUTION: An active matrix substrate 3 has a nickel plating layer 45b formed on the surface of a transparent conductive film 4 when a pixel electrode 40 is formed, so it can be used for a reflection type liquid crystal display device. When the nickel plating layer 45B is not formed after the transparent conductive film 41 is formed, this substrate can be used for a transmission type liquid crystal display device. To form the nickel plating layer 45B, an TFT(thin film transistor) is turned on through a terminal group, a scanning driver part, and a scanning line 150 and the transparent conductive film 41 is fed with electricity through the terminal group, data driver part, dataline 310, and TFT to perform electrolytic plating, so the open state of the pixel electrode 40 can be detected from whether or not there is the nickel plating layer 45B is present.

Title: Optical isolator and light emitting module
Inventor: MATSUMOTO KIYOTO
IPC: G02B27/28
Filed: 1995-09-25
Abstract: PROBLEM TO BE SOLVED: To stabilize the oscillating state of a laser diode by making the incident edge surface of an optical isolator a curved surface shape to diffuse reflected light beams on the incident edge surface and to make reflected light beams to be reinjected into the laser diode small. SOLUTION: This light emitting module is constituted of a laser diode 11 outputting light beams, an optical isolator 31 whose incident edge surface 14 is of a projecting curved surface shape and an optical fiber 13 to which light beams passing through the optical isolator 31 are made to be inputted. Exit light beams from the laser diode 11 are converged by the lens effect being had by the incident surface 14 of the projecting curved surface shape to be coupled with the optical fiber 13. One part of the light beams of the laser diode 11 are reflected on the incident end surface 14, but since the incident edge surface 14 is of a convex face shape, reflected light beams are scattered and most reflected light beams do not return to the laser diode 11.  Moreover, optical axes of light beams converged by the incident end surface 14 coincide with the center axis 22 of the optical isolator 31. Thus, a flow loss in the optical isolator can be made minimum.

IPC: H02M7/48
Filed: 1990-09-14
Abstract: PURPOSE:To operate a motor at a variable speed by a PWM control type inverter having high efficiency by fixing the ratio of the amplitude of a carrier signal to that of a sine wave control signal to a predetermined value under a PWM control of an inverter main circuit. CONSTITUTION:A transistor 20a of an inverter main circuit 20 is controlled to be driven based on a PWM signal. In this case, control ratio (A2/A1) of the amplitude A1 of a carrier signal Sc to that A2 of a sine wave control signal Ss is fixed to '1'. When a motor 21 of 100V/60Hz specification is operated by 120Hz, a DC voltage converter 12 steps up the output voltage under V/F constant condition. In this case, the control ratio (A2/A1) of the amplitude A1 of the carrier signal to the amplitude A2 of the signal So of an inverter controller 22 is '1'. When the rotating speed of the motor 21 is reduced, the controller 22 remains '1' of the ratio, and the output voltage of the circuit 12 is stepped down by a microcomputer 23.

Title: Low frequency defrost outdoor device
Inventor: YANO MASAYUKI
IPC: F25B47/02
Filed: 1992-08-25
Abstract: PURPOSE:To obtain an outdoor device for a heat pump having a low defrosting frequency by forming an evaporator to be mounted outdoors of a pre-evaporator and a post-evaporator, passing the atmosphere through the pre-evaporator and then sending the atmosphere to the post-evaporator. CONSTITUTION:An evaporator is formed of a pre-evaporator 3 and a post- evaporator 4. The pre-evaporator 3 is a subcooler having a plurality of heat transfer tubes 13 disposed vertically. Moisture on the surfaces of the tubes can be cooled to a subcooling are below zero degree C with refrigerant flowing in the tubes 13. The post-evaporator 4 is an ordinary evaporator, in which a heat transfer tube 9 for passing refrigerant is so disposed as to perpendicularly cross the atmosphere to be heat exchanged with the atmosphere passed through the pre-evaporator 3 by a fan 16. Thus, it is heat exchanged with the atmosphere passed through the evaporator 3 by the fan 16. Thus, since the subcooler is used as the pre-evaporator, the atmosphere passe through the pre-evaporator is dehumidified to reduce a frosting amount of the post-evaporator of the ordinary evaporator. In this case, since condensed water is also cooled to the subcooling area, it is not adhered to the tubes but can be drained.
