Title: Monitoring device for pantagraph
Inventor: UEMATSU YASUSHI
IPC: B61L1/10
Filed: 1983-10-05
Abstract: PURPOSE:To prevent outbreak of an overhead line accident by passing the luminous flux projected by a light projector above an electric-train line toward a photodetector and emitting an alarm signal from an alarm device when the current collecting plate of a pantagraph passes the above-mentioned luminous flux. CONSTITUTION:A light projector 1 and a photodetector 2 are attached to face each other and are so installed that the luminous flux projected by the projector 1 passes above an electric-train line and enters the photodetector 2. An alarm device 3 is attached to a column A and is connected to the photodetector 2 by a cable. Even if the electric-train line T advances into the luminous flux projected by the projector 1, no signal is outputted. An alarm signal is outputted when the current collecting plate P of the pantagraph passes through the above-mentioned luminous flux. The point where the overhead line fault by the pantagraph is generated is thus easily searched and the outbreak of an overhead line accident is prevented.

Title: Gas-blast circuit breaker
Inventor: MIZOGUCHI HITOSHI
IPC: H01H33/91
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To provide a gas-blast circuit breaker which has high breaking performance with less driving energy. SOLUTION: A floating base 23 to be energized frontward by a spring 24 is arranged inside a current collecting cylinder 21 to form a compression space S2 with the small inner diameter 4b at the rear end of a movable cylinder 4, a piston 8 and the collecting cylinder 21. The axial length L2c of the compression space S2 is almost the same as a travel length in pole opening operation. In pole opening operation, the compression space S2 is increased in pressure as reduced in capacity, thus so feed gas into a hot pressure-increased space S1 . When the compression space S2 is excessively increased in pressure, the floating base 23 is moved back to open a communication hole 21d in the collecting cylinder 21, release gas in the compression space S2 into an outside gas filled atmosphere and reduce it in pressure.  In this way, the hot pressure- increased space S1 is more increased in pressure while the compression space S2 remains less increased in pressure.

IPC: A61G5/04
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To make it possible to use the controller with the long life even with a compact controller without generating arcs at a relay contact, by detecting the operating times of two relays, which switch the conducting direction to a motor, adjusting the relay switching timing at the reverse braking time based on the detection, and synchronizing the conductions of both relays. SOLUTION: A control base board 13 controls the rotating speed of a motor M through a motor control circuit 14 based on the control signal from a key switch 10, an accelerator lever 11 and a forward/backward changing switch 12. Furthermore, the control base board 13 inputs the temperature values of the motor control circuit 14 and the control base board 13, and inputs the detected values of the elapsed times from a timer 18. When the accelerator lever 11 becomes OFF, the normal speed reduction is performed first of all. When the motor is not stopped by this process, two relays for switching the conducting direction to the motor M are switched by adjusting the timing based on the operating time difference of both relays detected beforehand. The current conduction is synchronized, and the braking is moved to the reverse mode.

Abstract: PURPOSE:To prevent a specimen holder of an X-ray diffraction device by employing molybdenum for making a high-temperature specimen holder of a specimen heating device. CONSTITUTION:After a specimen was not on a specimen holder made of molybdenum plate, the specimen is analyzed by conducting an X-ray diffraction at a high temperature using a specimen heating device. While platinum has conventionally been used for making the specimen holder, when an X-ray diffraction of a samarium-cobalt type magnet is executed at a high temperature, since samarium is a metal which is easily evaporated at a high temperature, samarium and platinum react with each other allowing a compound called Sm2Pt to be formed on the surface of the specimen holder and causing the specimen holder to become brittle and vulnerable, and thus occurring damage of the specimen holder is enabled to be prevented by taking advantage of the chemical characteristic that molydbenum and rare earth element do not produce any intermetallic compound.
