Title: Electrolytic capacitor
Inventor: MIYAZAWA HISAO
IPC: H01G9/10
Filed: 1989-04-07
Abstract: PURPOSE:To improve electric characteristics and service-life by sealing the aperture part of a case with a rigid insulative sealing member provided with a groove having a circular arc type bottom on the upper surface peripheral part and with which groove an elastic member is engaged. CONSTITUTION:When rigid insulator like phenol resin is molded, an aperture sealing member 4 is constituted by molding a rivet 7 en bloc; an elastic member 6 being an O-ring made of rubber is engaged with a circular arc type groove on the upper surface peripheral part of the aperture sealing member 4. Hence the permeation of halogen based organic solvent and the like into the inside of the electrolytic capacitor from the outside can be reduced; further the evaporation of electrolyte for driving in the inside of the electrolytic capacitor toward the outside can be prevented. Thereby stabilization of characteristics and long life can be realized.

Title: Assembly using magnetic fluid
Inventor: YAMAGUCHI TAKEO
IPC: H02K37/22
Filed: 1987-04-10
Abstract: PURPOSE:To improve the reliability and endurability as an inertial damper, by filling up magnetic fluid in the annular space and by holding it with the flux in the gap. CONSTITUTION:Together with a permanent magnet 8 rotates a shaft 1 performing rotating motion. An inertial ring 9 rotates, however, at the speed slightly slower than the rotating speed of the shaft 1 owing to the friction between the permanent magnet 8 and magnetic fluid 4 and between the magnetic fluid 4 and inertial ring 9. If the shaft 1 is going to rotate at the speed higher than the average speed with the unevenness in rotation of a driving device, the rotating force will be reduced by the friction with the magnetic fluid 4. On the contrary, if it is going to rotate slower, the rotating force of the inertial ring 9 will act as a movement to rotate the permanent magnet 8, i.e. the shaft 1 faster through the magnetic fluid 4 since the inertial ring 9 rotates faster. In this way, the unevenness in rotation is reduced for the shaft 1 and the shaft 1 will be rotated smoothly at the speed as close as to the average speed.

SOLUTION: In a shower device 1 to be used in a bathroom on the like, a cutoff valve 20 is mounted on the upstream side of a rubber hose 2 and a shower head 4 having a water discharge port 3 is provided with a switching valve 6. Because hydraulic pressure P1 , P2 of pressure chambers 24, 40 is equal in a state that this switching valve 6 is closed, a differential pressure operating valve 23 is closed. Next, when the switching valve 6 is opened, the differential pressure operating valve 23 is moved upward and is opened because hydraulic pressure P2 of the pressure chamber 40 lowers. As a result, water is flowed from a communicating path 29 and is discharged from the water discharge port 3 through the rubber hose 2.  Because hydraulic pressure P1 of the pressure chamber 24 is maintained higher than hydraulic pressure P2 of the pressure chamber 40 also at the time of water passing and the differential pressure operating valve 23 is held in a state that the valve 23 is moved upward, discharging is continued.

Filed: 1998-04-02
Abstract: PROBLEM TO BE SOLVED: To correctly measure a temperature of an object to be measured by rotating a thermocouple roller having a thermocouple provided on a surface in touch with a surface of the object. SOLUTION: This touch type temperature sensor has a thermocouple roller 1 which is provided with a thermocouple at a surface and is set rotatably to a sensor main body.

A friction heat resulting from a sliding contact as in the prior art is not generated when a temperature of the object is measured. The sensor main body includes a pair of holding levers 2, 3 for supporting the thermocouple roller 1 rotatably, operation levers 4, 5 and an operation display box 6. A temperature output of this touch type temperature sensor is input to a temperature regulator, whereby the temperature of the object can be correctly controlled without measurement errors.

Abstract: PURPOSE:To obtain the title compsn. providing a uniform molded item even if it is poured and exposed in a mold having the same temp. as the molding temp. of a material to be compounded, by incorporating a specified amt. of a specified mixed catalyst together with other components. CONSTITUTION:The title compsn. is obtd. by compounding a polyol (A), a crosslinking agent (B) (including a chain extender), water (C), a polyisocyanate (D) and a catalyst (E) in such a way that the catalyst (D) consists of a combination of an amine catalyst (a) and an organometallic catalyst (b) and the ratio is in the range of a/b of 100/5-100/20 and the amt. of the catalyst E to be added is in the range of 0.5-5 pts.wt. based on 100 pts.wt. of the sum of the components A, B, C and D. When this compsn. is used in a process where a polyurethane resin is poured in a mold a part or the whole of the inner face of which is kept at 110 deg.C or higher and expanded therein to obtain a molded item, even if the resin is exposed to a high temp. on pouring into the mold, poor flow and nonuniformity of quality such as shrinkage and breakage of cells hardly occur and a uniform molded item can be obtd. thereby. It is therefore unnecessary to bring the mold temp. to 80 deg.C or lower as in the conventional process and it is thus possible to improve drastically the molding cycle.
