Title: Valve opening/closing degree display device and valve opening/closing degree resetting method
Inventor: MATSUMOTO KENTARO
IPC: F16K37/00
Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To provide a valve opening/closing degree display device that can be fitted to and detached from an existing valve. SOLUTION: A fixed frame 24 is fitted in a detachable state to a shaft part 17A. The fixed frame 24 is provided with a driven pulley 40 receiving rotation of a rotatably fitted driving pulley 20 through a rotation transmission belt 42, and a counter display device 38 is fitted to the driven pulley 40. The fixed frame 24 is provided with a cutout hole 28A, while a rotation preventive fitting 22 is provided with a protrusion, and the protrusion is fitted into the cutout hole 28A. In a gate valve 16 fitted with such a valve opening/closing degree display device 18, when a handle 17 is rotated, rotation is transmitted to the driven pulley 40, and the counter value of the counter display device 38 is increased/decreased according to the rotating direction of the driven pulley 40.  Since the initial opening/closing degree of the valve corresponds to the reset value of a counter, resetting into an initial state can be easily performed after the change of an opening/closing degree.

Title: Photodetector
Inventor: YAMAMOTO MOTOHIKO
IPC: H01L27/14
Filed: 1985-12-02
Abstract: PURPOSE:To enhance resolution by separating a substrate and a photodiode by a dielectric layer and setting only carrier generated in the photodiode to a signal current. CONSTITUTION:Photodiodes PD1, PD2... are formed between P-type layers 4 and N<+> type diffused layers 5 in regions separated by dielectric layer 3 formed on a substrate 1. According to this configuration, since the photodiodes PD1... are insulated from the substrate 1, carrier generated in the substrate 1 does not become signal current of the photodiodes PD1..., but only carrier generated in a portion separated by the layer 3 becomes a signal current of the photodiode PD1.... That is, the photodiodes PD1... which sense its light is specified according to an incident position to perform a photodetector having high resolution.

Title: Method for estimation degree of deterioration of insulation
Inventor: TANIGAKI SHUZO
IPC: G01R31/12
Filed: 1990-10-12
Abstract: PURPOSE:To enable degree of deterioration of insulation on a surface of a solid insulator to be estimated easily by comparing a value obtained by measuring a color phase, etc., of the surface of the solid insulator with a spectral color difference meter with a previously produced calibration curve. CONSTITUTION:An SF6 gas, or a mixed gas of SF6 and air, etc., is used as an insulating gas to be used for gas-insulated equipment. The insulating gas is decomposed due to high energy which is generated by a partial discharge which is generated within the gas-insulated equipment, thus producing very reactive gas and very corrosive products. The state of the surface of the solid insulator is measured by the SF6 gas and the decomposed product using a spectral color difference meter and the measured value and an amount of total partial discharge electric charge are compared, thus enabling the amount of total partial discharge electric charge within the gas-insulated equipment to be known according to color phase change of the solid insulator surface so that the amount of total partial discharge electric charge can be obtained from a value obtained by measuring color phase change using the spectral color difference meter and a calibration curve by creating the calibration curve showing correlated relationship between the color phase change and the amount of electric charge previously and based on this the degree of deterioration of insulation of a solid insulator can be estimated.

Title: Vapor growth of gallium arsenide epitaxial crystal
Inventor: ARAI KENICHI
IPC: H01L21/338
Filed: 1986-11-17
Abstract: PURPOSE:To enable an epitaxial wafer which can provide a high-quality FET to be manufactured with a high yield by forming a first buffer layer while supplying oxygen gas onto the source gallium, and forming a thinner second buffer while supplying arsenic trichloride. CONSTITUTION:Vapor phase growth is initiated by causing a mixed gas of AsCl3 and H2 to flow through a gas supplying pipe 12, and simultaneously O2 is caused to flow through the gas supplying pipe 13, forming a first buffer layer 2 having a thickness of about 4.5mum. Thereafter the supply of O2 is stopped, and simultaneously a mixed gas of AsCl3 and H2 is caused to flow through the gas supplying pipe 12, forming a second buffer layer 3 having a thickness of about 0.5mum. With this, a buffer layer having a desired thickness and having less deep impurity levels in the neighborhood of the interface with an active layer can be obtained without degrading the external appearance of the epitaxially grown layer surface.

Title: Scissors sharpener
Inventor: ORABUI RINDEN
IPC: B24B3/52
Filed: 1990-10-12
Abstract: PURPOSE: To excellently sharpen scissors without imparting a sliding feeling by arranging a locking device to check rotation of rollers when grooved sharpening rollers rotatably installed in a main body move along scissor blades toward a scissor hinge from the blade tips as well as to allow rotation of the rollers when the rollers move in the opposite direction. CONSTITUTION: The tips of scissor blades 6, 7 are inserted into openings 4, 5 of a sharpener so that grips are mutually pressed down by proper force like cutting time. Next, when the scissor blades are more deeply inserted into the openings, while an upper side roller 14 thereby rotates in the clockwise direction, a lower side roller tries to rotate in the anticlockwise direction. As a result, the edge part of a wedge 16 checks rotation of the rollers by partially entering between the rollers, so that the blade surface 13 of the scissor blades is sharpened by the sharpening surface of the rollers.  Next, a fine tooth is formed on the blade surface by grooves of the rollers after the rollers 14, 15 start to rotate in the inverse direction since the roller surface pushes out the wedge from the meshing part of the rollers when the scissor blades are pulled out of the openings of a main body.
