IPC: H01R35/04
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To prevent the buckling of a cable in sudden relative rotation between inside and outside cylinders by arranging in C shape plural guide members along a base member extending in the circumferential direction. SOLUTION: When an inside cylinder 11a is suddenly rotated clockwise, a cable 13 is rewound from the cylinder 11a, comes in contact with the inner circumference of a moving body 21, turns reversely at the other opening end 21b, and moves to the outside of the moving body 21. Time is needed until the moving body 21 reaches the specified rotating speed by the force of the cable 13 reversely turning at the opening end 21b. At the moment of start of rotation, the moving body 21 becomes stop state. The excess cable 13 pushed out by the rotation of the cylinder 11a pushes outward the inner circumference 21d of the moving body 21, each guide member 212 swings to outer circumference by using a connecting hole 212a as a fulcrum, and the excess cable 13 is absorbed.  Even when the cylinder 11a is suddenly rotated, the buckling of the cable 13 caused by protruding from the opening part 21c of the moving body 21 can be prevented.

IPC: H03K17/73
Filed: 1990-10-15
Abstract: PURPOSE:To easily ensure a DC breakdown voltage of a GTO even when a gate driving power supply is lost by short-circuiting a gate and a cathode of the GTO when a means detecting the voltage drop of the gate driving power supply is activated. CONSTITUTION:When interruption of a gate driving power supply 51a of a GTO gate driving circuit 10 takes place, an auxiliary relay 100 is deenergized at the time point when the voltage is less than a prescribed threshold voltage, the contact B of the auxiliary relay 100 short-circuits the gate and the cathode of a GTO 1, resulting that the resistance between the gate and the cathode of the GTO 1 goes to zero. Thus, the DC breakdown strength is improved and the DC breakdown voltage of the GTO 1 is ensured similarly to the case when a negative bias voltage is normal. Thus, even when the loss of the gate driving power supply takes place, the DC breakdown strength of the GTO is easily ensured.
