Title: Variable capacity vane pump for power steering device
Inventor: INAGUMA YOSHIHARU
IPC: F04C14/22
Filed: 1983-04-21
Abstract: PURPOSE:To effect pressure relief without changing the amount of eccentricity of an eccentric ring and stabilize the pressure-flow amount characteristics by a method wherein a pressure chamber, consisting of a pump housing and a movable eccentric ring, is separated into two enclosed chambers and both of them are communicated with each other by a choke. CONSTITUTION:The housing 20 is formed with a rotor shaft 40, an inner port 20 and locating pins 44, 45 to determine the phases of the side plate 41 and a pressure plate 42. The eccentric ring 21 are guided movably in only the horizontal direction thereof by both locating pins 44, 45 and the pressure chamber around the eccentric ring 21 is separated into first and second pressure chambers 24, 25. Both of the pressure chambers are communicated mutually by a small diametral step part 44a which is forming the choke. Due to the pressure difference before and after the choking of the rotation of the rotor, the eccentric ring 21 moves a spring 64 to the compressing direction, reduces the amount of eccentricity to reduce the amount of delivery per one rotation and, thus, a compensating effect to make the passing flow amount constant is effected.

Title: Measuring method and measuring device of groundwater level
Inventor: SATO IESATO
IPC: G01V1/00
Filed: 1995-03-29
Abstract: PURPOSE: To take groundwater level measurement by which a change of ground water level as predictive data for natural disasters such as an earthquake, a landslide and so on can be grasped precisely. CONSTITUTION: Air vibration (noise) generated in an observation well B is detected by a vibration sensor 1. A columnar resonance vibration existing in the observation well B is extracted from the air vibration by the processing of a CPU 6. A groundwater level is computed from the relationship among an air column D (a height H from the upper end opening part of the observation wall B to the groundwater level), a sound speed and a columnar resonance vibration frequency. (The groundwater level is equivalent to the above height H). Thus, it is possible to take a measurement which has high response speed and can favorably follow up a short-period and sudden change of the groundwater level, and the change of the groundwater level can be grasped precisely, so that it is possible to obtain the data on the groundwater level as predictive data for natural disaster phenomena.

Title: Preparation of substrate for optical data memory medium
Inventor: SATO TETSUYA
IPC: G11B7/26
Filed: 1989-03-27
Abstract: PURPOSE:To reduce the strain and double refraction of a sheet and to well transfer the unevenness of a stamper by holding the introducing part of the sheet of the last third roller to high temp. while holding the leading-out part of the sheet thereof to low temp. to gradually cool the sheet to separate the same from the roller. CONSTITUTION:The temp. of the polycarbonate sheet 2 extruded from an extruder 1 is usually softening temp. of about 250 deg.C and the temp. of a press roller (first roller) 4 is set to about 120 deg.C and that of a molding roller (second roller) 3 is set to about 140 deg.C. Usually, the temp. of a press roller (third roller) 5 is set to 140-150 deg.C. The setting of these temps. is performed because the sheet 2 can be smoothly transferred when the temp. of the next roller is higher than that of the previous roller at the time of transfer. When the temps. of both of the first and second rollers 4, 3 are lowered, the generation of strain is caused and, when the temp. of the second roller 3 is further lowered, the transfer of the unevenness of the molding roller to the sheet becomes inferior and, therefore, said temp. can not be lowered. By providing a heat gradient to the third roller 5, the sheet is smoothly transferred from the second roller 3 to the third roller 5 and gradually cooled on the third roller 5 to obtain a sheet reduced in strain.
