Title: Laser scanning position-detecting sensor
Inventor: IKEDA TERUYUKI
IPC: H04N1/047
Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To correctly detect a scanning position of a laser light scanned at high speed by setting a lens for concentrating the laser light to one point of an irradiation position-detecting element for only a predetermined time when the laser light scans a laser scanning position-detecting sensor. SOLUTION: A lens 101 is optically designed so that a laser scanning light instantaneously enters a photodiode 103 when the laser scanning light is brought to a start point 101a of the lens 101 and the laser scanning light is condensed to one point of a position-detecting element (PSD) 102 for a predetermined scanning time thereafter. Even when the laser light is scanned at high speed, the laser light scanned from a laser unit to pass the laser scanning position- detecting sensor is temporarily held still to the PSD 102. A detect signal output from the PSD 102 can be taken when it becomes a stable state, so that a scanning position of the laser light can be correctly detected.

Title: Semiconductor pressure sensor
Inventor: SASAKI OSAMU
IPC: G01L9/04
Filed: 1988-01-22
Abstract: PURPOSE:To measure a pressure without error caused by a leakage current and suppress complicated distortions on the surface and rear of a semiconductor pressure sensor by a method wherein an insulating film is formed on the rear of the semiconductor pressure sensor which is brought into contact with a measured object and further a film whose thermal expansion coefficient is approximately equal to that of the insulating film is formed as an outermost layer on the surface. CONSTITUTION:A semiconductor pressure sensor chip 13 has a construction wherein an insulating film 11 is formed on the rear of a semiconductor substrate 1 where a diaphragm 6 is formed as a pressure-sensitive film. Further, a protective film 12 made of material which is the same as the material of the insulating film 11 or whose thermal expansion coefficient is approximately the same as that of the insulating film material is formed on the surface as an outermost layer. As the insulating film 11 is formed over the whole rear of the semiconductor substrate 1, even if the pressure of conductive liquid such as water solution is to be measured, the diaphragm 6 touches the liquid with the insulating film 11 between. Therefore, a leakage current from the semiconductor substrate 1 to the water solution which is the measured object can be avoided. With this constitution, balance/unbalance states of a bridge circuit composed of diffused resistors 2 can be correctly measured and the accuracy and reliability of the measurement can be improved.

Abstract: PURPOSE:To produce the title elastomer excellent in moldability, abrasion resistance and elastic properties, by reacting a specified polyamide with a specified polyoxyalkylene glycol under specified conditions and completing the reaction in a high vacuum. CONSTITUTION:Adipic acid is reacted with nylon 66 salt to obtain a polyamide of an average-MW of 300-5,000, having carboxyl groups on both ends.

Title: Semiconductor laminated layer structure
Inventor: NISHI KENICHI
IPC: H01L29/812
Filed: 1987-01-21
Abstract: PURPOSE:To operate a semiconductor laminated layer structure at a high speed by reducing the mobility of holes when an electric field is not applied in a laminating direction, increasing it when the electric field is applied, and generating the variation by the reversion of the energy value of base level in the potential well of heavy and light holes. CONSTITUTION:Since the energy value of base level 111 of light holes when an electric field is not applied to hole runner 105 in a laminating direction is larger than that of base level 113 of heavy holes, the holes exist only at the base level 111 of the light holes. In this case, the mobility of the holes in the laminating plane is approx. 100 cm<2>/v.s. When a voltage is applied between electrodes 107 and 108, the energy value of the base level 111 of light holes is smaller than that of the base level 113 of the heavy holes, and the holes exist only at the base level 113 of the heavy holes. In this case, the mobility is approx. 3000 cm<2>/v.s. Thus, a high speed operation is obtained by largely varying the mobility of the holes by applying an electric field in a laminating direction.

Abstract: PURPOSE:To obtain an alloy which permits easy and exact control of compsn. and concn. by spraying a particulate metal which consists of >=2 kinds of molten raw material metals and is supplied into plasma flow to an object to be thermally sprayed to form an alloy layer then separating said alloy layer therefrom. CONSTITUTION:The plasma flow is formed by an ordinary plasma generator in a nonoxidizing atmosphere consisting of a rare gas such as He having preferably a low pressure lower than the atmospheric pressure. The particulate metal formed by supplying and melting at least two kinds of the raw material metals, for example, prescribed ratios of Ni powder and Ti powder into the plasma flow is sprayed to the object to be thermally sprayed to form the alloy layer. A metal such as, for example, Al, Zn or Mg is used for the above-mentioned object to be thermally sprayed. The above-mentioned alloy layer is separated from the object to be thermally sprayed, by which the intended alloy is obtd. Since the alloy is supplied to the plasma flow of a high temp. the metals are instantaneously heated and melted. The oxidation of the metals is thus prevented and the fluctuation of the compsn. during the production process is decreased.
