Abstract: PURPOSE:To shorten the working time in underwater laying, to prevent the fluctuation in space between sensors and to make it possible to perform highly reliable measurement by independently making the underwater weights of sensors and signal cables for connecting the sensors to be approximately zero. CONSTITUTION:A cable 7 comprises a conductor 10 made of a copper wire having a diameter of 0.3mm and a polyethylene cover 9 having a specific gravity of 0.91. The diameter of the cable 7 is 2.5mm. Thus the underwater weight of the cable becomes zero. The specification of the cable so as to make the underwater weight to be approximately zero is set, and the similar computation is performed for a sensor 8. In consideration of the specific gravity and the volume of constituent members including cabinets and the like, the specifications are determined so that the underwater weight becomes approximately zero. In this way, the underwater weights of a plurality of the sensors 8 and the cables 7 for linking the sensors which are expanded horizontally are independently made to be approximately zero, respectively. Therefore, it is not necessary to provide a float for giving buoyancy. The man-hours of attaching works in laying can be saved.

Abstract: PURPOSE:To effectively reduce the vibration generated by the drive of a compression element by utilizing a dead space by installing an additional inertial body through a buffering body on the outer peripheral lower part side outside in the radial direction, on the revolution center shaft of the compression element of a casing.

Title: Pressure reduction valve
Inventor: SHIRAI SOICHI
IPC: G05D16/10
Filed: 1988-11-15
Abstract: PURPOSE:To ensure the quick and smooth flow of a fluid to a primary path from a secondary path by adding a link path and a check valve to a connector which connects a poppet (valve body) to a piston. CONSTITUTION:A connector 17 contains a link path P8 and a check valve 30. The pressure of an air pressure source AS is eliminated so that a fluid flows to a primary path P1a from a secondary path P1b with change of the flowing direction. Thus the fluid in a pressure room R1 flows to the path P1a through the path P8 and the valve 30 of the connector 17. As a result, the pressure is rapidly reduced in the room R1 and a piston 21, the connector 17 and a poppet 14 are quickly pressed by a spring 22. Then the poppet 14 moves largely apart from a circular sheet 21a and a large path is formed between the poppet 14 and the sheet 21a. Thus the fluid flows fast to the path P1a from the path P1b through the large path.

Filed: 1988-11-15
Abstract: PURPOSE:To reduce the number of improper moldings and to prevent mixing of impurity ions by forming at least a screw of an injection mechanism for plasticizing a resin of ultra hard alloy. CONSTITUTION:A molten resin fed to a front part 5 of a cylinder is injected and filled in a cavity of a metal mold by a low injection pressure as a screw 3 is advanced. When the molten resin is solidified, an outer casing to seal an electronic component is formed. At least a screw 3, preferably both the screw 3 and a cylinder 2 at the side of an injection mechanism which plasticizes the resin are formed of ultrahard alloy so as to prevent the abrasion of the screw and cylinder when a silica contained in the resin is brought into contact with an inner surface of the cylinder 2 and an outer surface of the screw 3 in the plasticizing process. Accordingly, the abrasion resistance can be greatly improved as compared with the case when cast steel is employed. Therefore, in sealing and molding an electronic component using a thermoplastic resin, the generation of poor moldings and mixing of impurity ions can be prevented.

Filed: 1999-10-12
Abstract: PROBLEM TO BE SOLVED: To provide a heat treatment device, which can form a prescribed film of a low dielectric constant and has high treatment efficiency and to provide a substrate treatment device, incorporating the heat treatment device. SOLUTION: Nitride gas flown into a chamber 15 from a gas supply port 16 is diffused by a diffusion filter 18, forms a uniform laminar flow flowing in a horizontal direction, and flows out from an opening 41. Thus, the flow in of outer air is prevented, and the inner part of the chamber 15 is maintained to a low oxygen concentration atmosphere. In the chamber 15, a heater 30 heat-treats a substrate. Thus, oxygen molecules are prevented from being taken into a film on the substrate, and the dielectric constant of the film can be lowered. Since the substrate W can speedily be cooled by holding a substance W on a transfer arm 60, where cooling water is circulated, treatment time becomes short, and high treatment efficiency can be provided.
