Title: Condensation-proofing vinyl wall covering
Inventor: HORIKAWA JIROU
IPC: B32B5/18
Filed: 1983-10-07
Abstract: PURPOSE:To provide the titled wall covering free from the formation of wrinkles caused by the elongation of the substrate nor the generation of mold in the paste, and usable for a long period without causing the surface waviness and peeling, by providing a water-impermeable layer between the substrate and the foamed layer composed mainly of a vinyl chloride resin and containing a highly water-absorbing polymer. CONSTITUTION:The objective wall covering is composed of (A) a foamed layer made of a resin composition consisting of (i) a vinyl chloride resin, (ii) a highly water-absorbing polymer having an average particle diameter of <=100mu, preferably <=50mu and capable of absorbing >=30 times weight of water based on own weight, and (iii) a plasticizer, (B) a substrate (e.g. paper, cloth, nonwoven cloth, wood plate, etc.) and (C) a water-impermeable layer, preferably a non-foamed vinyl chloride resin having high adhesivity to the foamed layer and excellent moldability, between the foamed layer A and the substrate B. The highly water-absorbing resin is a polyelectrolyte containing carboxylic acid salt and having crosslinked structure, preferably a saponified copolymer of a vinyl ester and an ethylenic unsaturated carboxylic acid (derivative). The amount of the water-absorbing polymer is 5-150pts.wt. per 100pts.wt. of the vinyl chloride resin.

Title: Compound semiconductor element and manufacture thereof
Inventor: OONAKA SEIJI
IPC: H01L31/107
Filed: 1983-10-07
Abstract: PURPOSE:To markedly reduce the dark current by decrease of surface leakage by a method wherein an N<-> InP trapezoidal N-InGaAs is superposed on an InP substrate, and a P type diffused layer is selectively provided while including the trapezoid. CONSTITUTION:An N<-> InP12 and an N<-> InGaAs13 are superposed on the N<+> InP substrate 11, an SiO2 mask being applied, and the layer 13 being then formed into a trapezoid by etching with the solution of Br+CH3OH. Next, an Si3N4 mask is applied, and Zn is diffused by the method of sealed tube, resulting in the formation of a P<+> InGaAs 14 and a P<+> InP 15. Au-Zn 16 and Au-Sn 17 are evaporated and then covered with a nonreflection protection film 18 of Si3N4 or the like. By this construction, the junction between the layers 13 and 14 is not exposed to the surface, and the surface leakage is small because of the exposure of the junction between the layers 12 and 15. Besides, the junction plane between the layers 13 and 14 does not generate field concentration because of being recess-formed, and the dark current therefore becomes smaller than the conventional element by 2-5 figures.

The Si3N4 film 13 and the SiO2 film 12 are selectively etched and removed with a mask 14. A substrate trench 15 is formed by anisotropic plasma etching by using the remaining SiO2 film parts 12a and the mask 14 as a mask so as to have its side walls 15a approximately perpendicular to its bottom wall 15b. After the mask 14 is removed, a polycrystalline Si film 16 is uniformly built up over the whole surface of the Si substrate including the substrate trench 15. After that, only the parts 16a of the polycrystalline Si film covering the whole surfaces of the side walls 15a are left by anisotropic plasma etching. Then the polycrystalline Si film parts 16a and the Si substrate part 11a of the bottom wall 15b are oxidized to form an element isolation part 17 made of SiO2 and the substrate trench 15 is filled.

Title: Heat generating resistance type flow rate measuring device and temperature error correcting means
Inventor: IGARASHI SHINYA
IPC: G01F1/698
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To correct readily a temperature error of a measured flow rate value by a method wherein a flow rate measured error due to a temperature change of a fluid is adjusted so as to be a constant ratio not by flow rate and measured flow rate value is corrected uniformly by a fluid temperature. SOLUTION: As a heat generating resistor 11 is controlled so as to increase always by a constant temperature with respect to a fluid temperature detected by a reference resistor 12, its current value is a signal corresponding to flux of a fluid. This current is replaced with a voltage by a resistor 17 and adjusted by an output characteristics adjusting circuit 14 to output a flux signal 15 to a control unit 4. Meantime, a fluid temperature detecting device 2 arranged in a fluid passage 40 outputs a voltage value at a time of supplying a resistance value per se or a constant current to a unit 4 as a temperature signal 22. The flow rate signal 15 is converted into a linear flow rate value by a flow rate convertion part 6, and further into a flow rate signal correcting a measured error due to temperature change of a fluid by a temperature correction part 3. Thereby, a flow rate value reducing the temperature error is obtained.

Title: Method of confirming soundness to oil leakage of cable line
Inventor: ISHIKAWA SHUZO
IPC: H02G15/26
Filed: 1989-07-21
Abstract: PURPOSE:To maintain the soundness of an OF cable line by a method wherein hydraulic pressure is applied from one tip of an OF cable by a pressure oil tank, the pressure oil tank and the OF cable are interrupted, the internal pressure of the OF cable is measured for approximately twenty-four hr, and soundness to oil leakage is made sure by the presence of an internal pressure drop. CONSTITUTION:Hydraulic pressure is applied from one tips of cables 4u-4w through valves 2u-2w by a pressure oil tank 1. Each valve 2u-2w is closed, the changes of hydraulic pressure in the cables 4u-4w are measured for twenty- four hr by pressure gages 3u-3w as internal pressure is left as it is held in the cables 4u-4w, and temperature changes are also measured simultaneously. When the internal pressure of the cables 4u-4w drops after the passage of twenty-four hr, the generation of oil leakage is decided, and the quantity of leakage oil is acquired by using a value calculated by observation at the time of the completion of cable 4u-4w lines.

Title: Current limit circuit for pwm amplifier
Inventor: MUKOGASA YUKIO
IPC: H02P7/29
Filed: 1990-07-18
Abstract: PURPOSE:To perform current limit operation stably with substantially no response lag even upon abrupt increase of load current by constituting a current limit circuit of a combination of a comparator, a flip-flop operable with the output of comparator and a synchronizing pulse, and an AND gate for turning a PWM pulse ON/OFF based on the output of the flip-flop. CONSTITUTION:When the load current is lower than a preset limit current level, a comparator 7 does not function and has L output level and thereby a flip-flop 10 is reset by a synchronizing pulse and has H output level. Consequently, a PWM pulse is applied, as it is, on the gate of a FET 2 through an AND gate 8 thus subjecting a motor 1 to chopper control according to a PWM pulse train. When the current value detected through a shunt 3 exceeds the current limit level due to abrupt increase of load torque of the motor 1, output of the comparator makes a transition from L to H to cause transition of the output of the flip-flop from H to L thus pulling the output of the AND gate 8 down to L level.
