Title: Torque transfer device using magnetic fluid
Inventor: TSUKAHARA YUJI
IPC: F16D37/02
Filed: 1989-12-19
Abstract: PURPOSE:To enable the arbitrary change of a torque transfer rate by liquid- tightly positioning a rotary shaft within a hollow case comprising a non- magnetic body, and so providing two rotors having many magnets or the like at respective ends of the rotary shaft as to be opposite to each other. CONSTITUTION:When a rotary shaft 8 is rotated as a drive shaft, for example, magnetic body particles contained in a magnetic fluid M strongly adhere like spikes to an area around a magnet 22 embedded in the external surface of a rotor 20. As a result, large resistance is generated between the fluid M and a blade 17 formed on the internal surface of the cylindrical part 152 of a rotor 15. This resistance works to transfer the torque of the shaft 8 to the blade 17 of the rotor 15 from a rotor 20 integral with the shaft 8 via the fluid M. Furthermore, the torque of the rotary shaft 8 is transferred to a rotary shaft 6 integral with the rotor 15 as a transfer axis. When the amount of the fluid M or the properties thereof is changed, a torque transfer rate can be arbitrarily changed between the shafts 6 and 8.

Title: Insulation resistance tester
Inventor: HIBI MICHIO
IPC: G01R27/02
Filed: 1987-12-25
Abstract: PURPOSE:To prevent a disturbance during the connection of an electronic appliance, by applying a voltage opposite in polarity to that during a measurement equivalent to a total amount of electric charge supplied to a cable to be measured during the measurement of an insulation resistance for a specified time to remove the electric charge left in the cable in a short time. CONSTITUTION:Insulation resistance of an electric cable 1 is measured with a tester 10. A discharge current waveform is measured using a voltage drop due to current passing through a resistance R in an insulation resistance measuring circuit of the tester 10 and stored with a measuring memory section 12. On the basis of the waveform, a total amount of electric charge supplied to the cable 1 is calculated with a control section 4. Moreover, a power source voltage opposite in polarity to the electric charge and application time thereof are calculated to be supplied to a switching power source 11 composed of a switch 2' for changing over one power source in the opposite direction. The control section 4 controls the switching power source 4 to supply a required power for a required time. Thus, electricity charged during the measurement of the insulation resistance is removed in a short time, thereby eliminating a disturbance other wise caused during the connection of an electronic appliance.
