Title: High precision measuring device for plasma energy distribution
Inventor: SHIMIZU KAZUO
IPC: H05H1/00
Filed: 1987-10-05
Abstract: PURPOSE:To enable measurement of energy distribution with high accuracy by varying a probe voltage in a step manner, and obtaining secondary difference of probe current in each step, thereby dispensing with application of an AC signal. CONSTITUTION:A stepped wave voltage generating circuit 1 generates a voltage varying in a step form, while a DC stabilizing power supply 2 generates a voltage equal to a part of steplike voltage variation to produce a voltage V1 after biasing a voltage V2. The voltages V1, V2 are respectively applied to probe electrodes P1, P2 installed in plasma, and respective probe currents flowing in the electrodes P1, P2 are detected by current detector circuits 3, 4, then the difference is obtained at a reduction circuit 5. After it is converted into a pulse number at a frequency modulation circuit 6, and counted at a counting circuit 7 at every respective step sections, and at an arithmetic circuit 8, the difference between counted results between fore-section and rear section. It is thus possible to obtain an energy distribution signal in proportion to second order difference in the voltage and current characteristic of the probe, and to enable a high precision energy distribution measurement.

Title: Nitride semiconductor laser device and manufacture thereof
Inventor: YAMADA TAKAO
IPC: H01S5/00
Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To obtain a laser beam whose projection direction is horizontal to a substrate in the beam center by preventing laser light, projected from a resonance face formed on a nitride semiconductor layer by etching, from being interrupted by a portion, including the substrate, protruded from the resonance face. SOLUTION: Resonance faces, opposed to each other, are formed on a nitride semiconductor layer by etching. Laser light resonates at the resonance faces and is projected from an active layer 3 at an angle of θ both in the direction of A and in the direction of B opposite to A. The title laser device is obtained by removing a portion, including the substrate, protruded from the resonance face in the direction of A. As a result, laser light, projected at an angle of θ, will not be interrupted by an end of the substrate 1, protruded from the resonance face. Thus, a laser beam whose projection direction is horizontal to the substrate in the center of the beam is obtained.

Title: Centrifugal compressor
Inventor: OKANO MAKOTO
IPC: F04D29/44
Filed: 1989-09-29
Abstract: PURPOSE:To simplify the structure and make a device compact and obtain the pressure as same as a conventional one by piling compression flow passages in multistage in one rotor vane, and connecting compressing mechanisms which consists of diffusers located in each flow passage in series to enable the multistage compression with one device. CONSTITUTION:Since a centrifugal compressor different from the conventional type centrifugal compressor has multiple diffuser parts independently separated, it has the characteristic equal to the operation of multiple centrifugal compressors simultaneously with one vane. Namely, the fluid sucked from a compressor inlet 27 is accelerated in a first stage compression flow passage of the rotor vane 11, name, the kinetic energy thereof is raised, and thereafter, the speed of the fluid is reduced in a diffuser part 24 of the first stage, and the pressure is raised. Furthermore, the fluid is led to a second stage and a third stage to raise the pressure in the same way, and finally the fluid sucked from the compressor inlet 27 is discharged to a compressor outlet 28. The three- stage connection is thereby formed through the whole, a centrifugal compressor having a large compression ratio can be realized.

Title: Production of hydrogel
Inventor: SHIMOKAWA WATARU
IPC: C08B31/00
Filed: 1985-11-11
Abstract: PURPOSE:To produce a hydrogel which has good transparency and causes extremely small syneresis both at low temperature and at high temperature, by allowing an aqueous solution of an acetoacetylated water-soluble polymeric compound to gel by crosslinking with a specified crosslinking agent at room temperature. CONSTITUTION:An acetoacetylated water-soluble polymeric compound (e.g., PVA) is allowed to gel by crosslinking by mixing it with a crosslinking agent therefor [e.g., N-beta-(aminoethyl)-gamma aminopropyltrimethoxysilane]. Conventional natural gel products such as agar-agar or alginic acid require a step of dissolution by heating and, besides, the obtained gels have drawbacks of fragility, weakness and extremely poor transparency. A hydrogel obtained by adding boric acid or borax to a PVA solution has drawbacks of weakness and syneresis upon freeze-thaw cycle or upon prolonged storage at high temperature. According to the process of this invention, the obtained gel is advantageous in that it can be produced at room temperature and has good transparency and causes extremely low syneresis both at low temperature and at high temperature.

Abstract: PROBLEM TO BE SOLVED: To prevent drawing by actuating a windowpane by providing an auto-up latch circuit, an auto-down latch circuit, a motor and the driving circuit, and an auto-up-off circuit. SOLUTION: When a car is inundated with water, an auto-up latch circuit 19 is put on and also an auto-down latch circuit 21 is put on. As an auto-up-off circuit 23 is provided in the output side of the circuit 19, current leaks through silk in the pattern of the circuit 23 and current flows between pads. The electrical voltage is applied to the base of a transistor through the pad and a resistance to put on the transistor. And hence, the auto-up signal of the circuit 19 is put off and the auto-up action of the windowpane is forcibly put off. Then, the auto-down signal from the circuit 21 is received and a motor 30 is rotated through a motor-driving relay 29 to automatically move down the windowpane. In this way, drowning can be prevented.
