Title: Absolute position detector
Inventor: AMAMIYA YOUICHI
IPC: G01B7/00
Filed: 1983-06-08
Abstract: PURPOSE:To detect the absolute position of the operation part of a system to be controlled easily with high precision in case of a power failure, disconnection of power source, etc., by coupling two rotational angle detectors to the rotating shaft of the system to be controlled so that rotating speed ratios of their electical angles are slightly different. CONSTITUTION:Bipolar resolvers 25 and 37 are fitted to the rotating shaft 24 of a motor 23 which drives an NC machine tool, etc., and a shaft 35, and the ratio of gears 34 and 36 is so set that the rotating speed ratios of electrical angles of the resolvers 25 and 37 are slightly different. Output voltages e1 and e2 of the resolvers 25 and 37 are sent to a phase discriminating circuit 33 and compared with a carrier from a carrier generating circuit 32 to calculate phase differences thetaa and thetab. Those phase differences correspond to the angles of rotation of rotors, and detection angle signals thetaa and thetab are sent to an arithmetic processing circuit 38 to calculate the total rotation amount of the rotors, i.e. absolute position of the system to be controlled from the rotating speed ratios from a specific equation. Consequently, the absolute position of the driving part of the system to be controlled is detected easily with high precision in case of a power failure and a disconnection of the power source.

Title: Light-weight banking method
Inventor: MAHIRA KOUICHI
IPC: E02D17/18
Filed: 1995-04-25
Abstract: PURPOSE: To provide the light-weight banking in a short period without generating deformation and ground settlement by piling foaming resin blocks on the ground so as to construct a foundation structural body, and arranging asbestos cement boards thereon so as to form the asphalt pavement. CONSTITUTION: Foaming resin blocks 2 made of polystyrene, etc., are piled on the ground 1, and the side surface thereof is covered with the cement hardened material 4 so as to form a wall, and the top surface is coated with the asbestos cement board 3. Furthermore, asphalt 5 is paved thereon so as to construct the foundation structural body of a platform or the like. In this case, the asbestos cement board 3 is formed at the thickness, which can prevent the transmission of the heat at the time of paving the asphalt 5 to the foaming blocks, and sand and dry mortar or the like can be laid under the asphalt 5. Plural asbestos boards 3 can be piled. Generation of deformation and breakdown of the foundation structural body and the generation of the ground settlement can be thereby eliminated. The light and strong banking can be thereby obtained in a short period.

Title: Germicidal composition
Inventor: MOCHIZUKI NAOKI
IPC: A01N25/10
Filed: 1982-06-14
Abstract: PURPOSE:A germicidal composition, containing a water-soluble high polymer, e.g. agar, carrageenan or polygalactomannan gum, having the gelation property and a germicide, and capable of dissolving chemical active components slowly in water and improving the water quality of a waste water for a long term. CONSTITUTION:A germicidal composition, containing a water-soluble high polymer having the gelation property and a germicide, e.g. the chlorine type and cationic type, and useful for waste water. The composition repeats the following processes: If the germicide flows out of the surface of a polysaccharide, the surface part is attacked by germs and spoiled or dissolved to expose a new gelled surface containing the chemical active constituents and dissolve the chemical active constituents. Therefore, the dissolution rate of the chamical active constituents is controlled, and the chemical active consitiuents are enclosed in the gel according to the number of germs in the waste water. Thus, the germicidal effect will not be temporary even when a germicide having a high water solubility is used. The use of xanthan gum with locust bean gum, etc. provides a more remarkable gelation effect.

Title: Fluid pressure control valve
Inventor: TANAKA RYUICHI
IPC: B60T8/26
Filed: 1989-04-21
Abstract: PURPOSE:To attenuate a pulsation of the return pressure from a pump effectively without disturbing the liquid movement from the inlet side to the outlet side by providing a throttle device to generate a throttle function responding to the piston movement of a fluid pressure control valve. CONSTITUTION:When a piston 50 is moved to an inlet 18 side in the operation of a fluid pressure control valve 10, the larger diameter part 82 of a plunger 80 hits a step 12b by a spring 86. As a result, a groove passage 84 of the larger diameter part 82 functions as a throttle. Since the force of the spring 86 is small, the flow from the inlet side to the outlet 14 side is not disturbed by arranging the plunger 80, and the throttle device with the groove passage 84 throttles only the flow of the liquid from the outlet 14 side to the inlet 18 side. And the throttle function is effective only when the fluid pressure control valve 10 is operated. By such a throttle function, a pulsation of the return pressure from a pump, that is, a pulsation applied to the outlet 14 is attenuated.

When the N<-> drain region 1 comes into Schottky contact with the drain electrode 10, the N region 9 can be dispensed with.
