Title: Permanent magnet eddy current speed reducer
Inventor: OGAWA MAKOTO
IPC: H02K49/02
Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To provide a magnet eddy current speed reducer which has a ferromagnetic plate whose circumferential dimension is optimized for increasing braking torque without making a great change in structure. SOLUTION: Inside a braking drum 13 which is made of conductive material and is connected to a rotary shaft, a fixed guide cylinder 18 which is made of non-magnetic material and has a hollow section whose cross sectional shape is rectangular is coaxially located. Many ferromagnetic plates 21 are connected to an outer wall section 18a of the guide cylinder 18 which face the braking drum 13, at equal intervals in the circumferential direction. To a magnet supporting cylinder 19 which is so supported in the hollow section of the guide cylinder 18 that it can move in the axial direction, magnets 20 are so connected that their polarities against the ferromagnetic plates 21 may vary alternately in the circumferential direction.  An actuator 41 moves the magnet supporting cylinder 19 in the axis direction either to a braking position wherein the magnets 20 and the ferromagnetic plates 21 face each other or to a non-braking position wherein the magnets 20 and the ferromagnetic plates 21 do not face each other. The wall faces 21a at the ends in the circumferential direction of the ferromagnetic plates 21 are tilted so that the dimensions in the circumferential direction of the ferromagnetic plates 21 may become shorter as they come close to the braking drum 13.

Filed: 1985-12-28
Abstract: PURPOSE:To prevent cavitation by comparing a jet pump and a recirculating pump with the pressure and flow characteristic curves of both pumps and running back recirculating pump when the measured values are lower than the curves. CONSTITUTION:Individual pump flows from a jet pump 2 enclosed in an atomic reactor pressure container 1 and a recirculating pump 7 arranged in a recirculating pipe 6 connected to this container 1 are measured by flow measuring devices 20, 21 to generate flow signals 20a, 21a. The flow signal 20a detected by the jet pump 3 and the pressure signal 22a detected by the recirculating pipe 6 are fed to a comparator 24 and are judged whether to meet the jet pump characteristic A. When the pump characteristic is deteriorated from a dot (.) indicating a normal detection value to a circle (O) indicating a cavitation occurrence, a recirculating pump runback signal 25 is generated by the comparator 24. Accordingly, the recirculating pump 7 quickly runs back to prevent a cavitation occurrence.

Title: Heat exchanging system for hydrogen fueled engine
Inventor: WATANABE MASAHIRO
IPC: F02M21/02
Filed: 1988-11-21
Abstract: PURPOSE:To miniaturize a heat exchanger by arranging the heat exchanger on the path of exhaust gas system of a hydrogen fueled engine to recover latent heat from exhaust gas through the direct contact of the heat exchanger with exhaust gas. CONSTITUTION:Exhaust gas discharged from a hydrogen fueled engine 1 is introduced into a gas condenser 6 as a heat exchanger. Water 7a as the medium of the heat exchanger is stored in the gas condenser 6. Since the exhaust gas is directly blown into the water 7a, the water becomes warm by collecting latent heat from the exhaust gas, so that the latent heat can be recovered very efficiently from steam, making it possible to miniaturize the heat exchanger.

Title: Method for giving thermal shock to electronic parts, method for testing thermal shock, and thermal shock giving device used therefor
Inventor: MIYAZAKI KENTARO
IPC: G01R31/26
Filed: 1991-11-11
Abstract: PURPOSE:To continuously give thermal shocks to electronic parts by making a hoop material continuously carried while the hoop material carry a large number of electronic parts to pass through a high-temperature bath after passing through a cooling section. CONSTITUTION:Electronic parts 8,... carried on a hoop-like frame F are cooled as the frame F is carried by blowing compressed air upon the parts 8 from the nozzle 12a of a cooling section 12. After cooling, thermal shocks are given to the parts 8 by dipping the parts 8 in silicone oil 11 heated to, for example, about 260 deg.C in a high-temperature bath 9. When the parts 8 are dipped in the oil 11, the heat of the bath 9 is transferred in the direction opposite to the carrying direction of the frame F, but the cold temperature given to the parts 8 in the cooling section 12 before dipping is transferred through the frame F in the carrying direction, offsetting the heat transfer in the opposite direction and lowering the temperature of the frame F to about a room temperature at the moment the frame F is dipped in the oil 11. Thus the temperatures of the dipped frame F and parts 8 carried on the frame F impulsively rise. Therefore, thermal shocks similar to the severe thermal shocks expected when the parts 8 are mounted by dipping in a solder bath are continuously given to the parts 8.
