Title: Function part case for bubble generating bathtub
Inventor: HARAGA HISATO
IPC: A61H23/00
Filed: 1989-06-01
Abstract: PURPOSE:To prevent a bathing person, which is interposed in a route, from getting an electric shock by housing a circulating pump and an inverter in one function part case, mutually insulating the circulating pump and inverter and disposing them with an enough distance from the function part case as necessary. CONSTITUTION:A noise filter 42, power supply transformer 43, earth leakage breaker 44 and connector 45 are disposed on the upper direction of a circulating pump 2. In the other side upper direction of the circulating pump 2, a radiation panel 47 is faced to the inner surface of a function case part 10 and an inverter 13 is arranged through an insulating chassis 13a with holding an enough interval. Thus, since respective electric parts are insulated from the function part case 10 and a distance between the electric parts such as the inverter 13 and circulating pump 2 where a voltage equipped with a high frequency component is loaded, and the function part case 10 is made large, the current of low and high frequencies does not leak to the function part case 10 and even when the bathing person touches the function part case 10, there is no danger for the bathing person to get the electric shock.

Title: Hot water for bathing circulating pump driving circuit for bubble generating bathtub
Inventor: HARAGA HISATO
IPC: A61H23/00
Filed: 1989-06-01
Abstract: PURPOSE:To interrupt a high frequency current to be transmitted to a motor part and to prevent an electric shock even when the motor part, etc., is not completely grounded by providing an insulating transformer to interrupt the high frequency current between an inverter and the motor part. CONSTITUTION:An insulating transformer 40 is interposed between the inverter 13 and the motor part 21 and the high frequency current is made hardly flow. Namely, for the insulating transformer 40, a primary side coil 41 and a secondary side coil 42 are not connected but completely insulated and capacity coupling between the both coils 41 and 42 is reduced as much as possible so that the high frequency current can be made hardly flow between the primary side and secondary side. By such an insulating transformer 40, the route of the high frequency current between the inverter 13 and motor part 21 is interrupted. Thus, the insulating transformer 40 is interposed between the inverter 13 and motor part 21. Then even when the motor part 21 is not completely grounded, only the slight high frequency current leaks into hot water for bathing and the accident of the electric shock is prevented since the route of the leaking high frequency current is interrupted by the insulating transformer 40.

Title: Magnetic coupling
Inventor: KAMEOKA TERUHIKO
IPC: F16D1/06
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To reduce variation of magnetic gap (distance between first and second permanent magnets) in a magnetic coupling while suppressing increase in the manufacturing cost thereof. SOLUTION: Position of a second permanent magnet 160 is determined with respect to a first permanent magnet 130 by laminating a thrust bearing 110 and a spacer member 140. Consequently, the variation of a magnetic gap can be determined by accumulating the variation in the manufacture of the thrust bearing 110, the spacer member 140 and both permanent magnets 130, 160 and the variation in the assemblage can be substantially removed. According to the structure, variation of magnetic gap in a magnetic coupling 100 can be reduced while suppressing increase in the manufacturing cost thereof.

Title: Manufacture of catalyst for exhaust gas purification
Inventor: YAMASHITA KOICHI
IPC: B01J37/30
Filed: 1992-06-01
Abstract: PURPOSE:To prevent copper from aggregating and at the same time to improve further NOx purifying efficiency by providing a manufacturing method of a copper-carrying alumina catalyst to purify nitrogen oxides from exhaust gas containing excessive oxygen in the presence of a hydrocarbon. CONSTITUTION:Carrying copper on an alumina carrier is carried out by ion exchange in the way the mole ratio of coper atom to aluminum atom (Cu/Al) is controlled to be 0.01 to 0.1. Owing to the ion exchange to carry copper on the carrier, the copper is highly dispersedly carried and hardly aggregate, so that oxidation of hydrocarbon is lessened and the portion to be used for reduction of NOx is increased.

Title: Vibration sensing type automatic closing cock
Inventor: MIYAZAKI SHIRO
IPC: F16K17/36
Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To automatically close a cock using a simple mechanism simultaneously with generation of shaking due to earthquake by constituting the cock so that a weight detached and falling from a pedestal by vibration is added to the other end of an arm and hence the cock is rotationally moved to the full closing position. SOLUTION: At first, a weight 7 is stationarily placed on a pedestal 5. At this time, a cock is in the full opening position, and in the general cock a lever 2 projectingly provided on a gas feed pipe 1 is positioned in parallel with the feed pipe. When shaking or vibration on a fixed level is generated by earthquake, the weight 7 falls from the pedestal 5, and begins a pendulum motion centering around the fitted position with a flexible object such as chain 8 on the other end of a balance arm 3. At this time, the position to which the load of the weight 7 is applied is transferred to the other end of an auxiliary arm 4, and hence the lever 2 is rotationally moved up to the full closing position. Namely, the lever 2 is rotationally moved from the opening position to the closing position simultaneously with generation of vibration, and hence supply of gas or the like can be stopped.

Filed: 1985-06-27
Abstract: PURPOSE:To achieve the removal of play due to a backlash by making the distance between centers of engaging gears of the subject device being used for an industrial robot and the like variable. CONSTITUTION:The outer circumferential cylindrical surface 14a of a cylinder 14 is fitted in a housing 9 so as to be capable of turning, and then fixed. And, the center of an inner circumferential cylindrical surface 14b is made to be eccentric to that of the outer circumferential cylindrical surface 14a, and bearings 10 which support freely rotatably a main shaft 5 are fitted in the interior thereof. If the cylinder 14 is turned, the center of the inner circumferential cylindrical surface 14b moves on a circular orbit making the eccentricity as the radius, and accordingly the center of the main shaft moves also on the circular orbit. On the other hand, since the center of a follower gear is fixed, the center distance between the center of the follower gear and that of the main shaft can be adjusted within the range of twice the eccentricity. By this constitution, the play due to a backlash can be removed.
