Title: Torque limiter
Inventor: KAWASAKI TOSHINOBU
IPC: F16D43/202
Filed: 1990-10-01
Abstract: PURPOSE:To simplify constitution and reduce maintenance cost of a torque limiter by drawing one end out of an engaging part to slide and causing the other end to deform a cover and interrupt power transmission between both shafts when transmission torque exceeds a set value. CONSTITUTION:When transmission torque from an inner shaft 1 to an outer shaft 2 exceeds a set value, the contact surfaces of an engaging part 4 of the inner shaft 1 and a diverging recess part 6 of a torque transmission member 5 begin to slide on each other and thereby a torque transmission member 5 receives a force for extruding it from the engaging part 4 to be drawn out of the engaging part 4. As soon as the torque transmission member 5 is completely drawn out of the engaging part 4, the torque transmission member 5 slides radially outward in a through hole 3 to break through a thin part of a cover 8 with a hemispherical part 7 of the torque transmission member 5. Thus, the inner shaft 1 is rotated relative to the outer shaft 2 and the power transmission from the inner shaft 1 to the outer shaft 2 is interrupted. Further, the torque transmission member 5 is held by the broken part of the cover 8 and prevented from return to the engaging part 4 side.

Title: Compensating device for instantaneous reactive and active power
Inventor: KOBATA MASAKAZU
IPC: G05F1/66
Filed: 1985-11-26
Abstract: PURPOSE:To attain the instantaneous reactive and active power compensation with high accuracy by detecting the voltage of a smooth sine waveform at the primary side of a transformer. CONSTITUTION:This compensating device is provided with an AC system power supply 1, an AC reactor 3, a 3-phase PWM converter 4, a DC capacitor 5, a transformer 6, a voltage transformer 7, current transformers 8 and 9, and a controller 10. Both the input current and the compensating current of the load 2 are detected by the transformers 8 and 9. While voltage eu, ev and ew are detected by the transformer 7 connected to the primary side of the transformer 6. The voltage obtained by the transformer 7 is turned into a sine waveform including no high frequency produced by a fast switching action owing to the leakage inductance. Thus the controller 10 supplies the sine waveform voltage and performs the 2-phase/3-phase converting arithmetic. In such a way, the current command signals can be obtained in response to the instantaneous reactive and active power produced by the load 2.
