Title: Semiconductor sensor
Inventor: ITO TATSUYA
IPC: G01P15/12
Filed: 1994-12-09
Abstract: PURPOSE: To improve the precision of resistance value and facilitate the trimming work and shorten the working time by lessening the cutting quantity by laser trimming of a thin film resistor pattern indispensable for making the properties of semiconductor sensors uniform. CONSTITUTION: A metal thin film resistor 15 formed between wiring lines 16, 17 on the surface of a sensor chip is composed of a roughly adjusted trimming part 31 and a finely adjusted trimming part 32. The roughly adjusted trimming part 31 is formed as a winding ladder pattern having a plurality of narrow width parts 33 and a plurality of the narrow width parts 33 are connected with one wiring line 16. These narrow width parts 33 are cut by a laser trimming method and rough adjustment of the resistance value is carried out according to the number of the cut parts. Since the cutting quantity at the time of cutting of the narrow width parts is small, the resistance value does not become unstable.

Abstract: PURPOSE:To obtain a high magnetism-generating effect by shutting off the leakage magnetic flux from the surface of a magnet by a method wherein parts other than a part corresponding to a magnetic pole of the magnet are covered with a superconducting material. CONSTITUTION:A magnetism-generating body 10 contains a permanent magnet 12 of a round bar as a magnet; a coating layer 16 composed of a superconducting material is formed on the outer circumferential face exclusing magnetic pole end faces 14A, 14B at both tip parts. A superconducting substance such as an oxide of lanthanum, barium and copper, an oxide of yttrium, barium and copper or the like is to be used as the superconducting material. Because a superconducting phenomenon of the superconducting substance is revealed at an abslute temperature of about 90K which is higher than the boiling point of liquid nitrogen, a cooling chamber 18 is installed at the outer face of the coating layer 16; a coolant such as liquid helium, liquid nitrogen or the like is supplied and circulated inside this cooling chamber 18; the coating layer 16 is cooled; the superconducting phenomenon can be revealed. By this setup, a line of leakage magnetic force from the outer face of the permanent magnet 12 is shielded due to the Meissner effect and is not leaked to the outside; a line of magnetic force nearly close to a saturated magnetic flux density can be taken out from the magnetic pole end faces 14A, 14B.

Title: Engine high-altitude simulation tester
Inventor: HANAWA KICHINOSUKE
IPC: G01M15/00
Filed: 1991-11-22
Abstract: PURPOSE:To reduce the installation number of exhaust blowers without altering the operation mode of an air compressor by connecting an excessive air passage for guiding excessive air as the operation air of an ejector from the air compressor. CONSTITUTION:For example, at the time of the simulation test of a point B, excessive air 5' is generated. The air 5' at this time is guided to the ejector 14 on the downstream side as operation air through an excessive air passage 15 by operating valves 16, 17 and the exhaust gas 9 from an exhaust blower 11 is further sucked and discharged by the ejector 14 using said operation air. By this constitution, without substituting a part of air compressors 7, 8 for the exhaust blower of an exhaust system, the gas 9 can be easily raised in pressure to atmospheric pressure or more to be sucked and discharged. When a test is performed in the vicinity of a point A low in the amount of air 5', the pressure of the gas 9 becomes relatively high as compared with the case of the point B. By this constitution, the gas can be also easily raised in pressure to atmospheric pressure or higher only by the blower 11 to be discharged.

Title: Electrophotographic copying device
Inventor: YASUBA HIROSHI
IPC: B41J2/44
Filed: 1989-12-21
Abstract: PURPOSE:To keep a contrast potential on a photosensitive body constant and to obtain a stable printed image by previously storing the intensity of laser light made incident on the photosensitive body and controlling the intensity of the laser light made incident on the photosensitive body so that it may be equal to stored intensity. CONSTITUTION:At the time of setting an electrophotographic copying device, the contrast potential is set to be a constant value and the intensity of the light at that time is detected by a laser light intensity detector 26, then the detected value is stored in a driving circuit 21. When the device is used in a dusty room for a long time, the reflectance of a mirror is lowered, the transmissivity of a lens is lowered. In the case that the laser light enters in the detector 26 in such a state, the intensity of the laser light becomes weaker than the initially stored intensity of the laser light. Then, the driving circuit 21 is actuated to increase the potential applied to the laser light so that it may have the same intensity as the initial laser light. Thus, the constant contrast potential is always obtained.
