Title: Driving circuit for gate of gto thyristor
Inventor: ISHIDO MICHIHARU
IPC: H02M1/06
Filed: 1987-07-20
Abstract: PURPOSE:To reduce the power consumption of a gate driving circuit greatly by detecting and comparing the anode voltage of a gate turn-off thyristor(GTO thyristor) with a voltage of preset detection level, and stopping the operation of a gate current supply power source when the anode voltage is lower than the detection level. CONSTITUTION:When the anode voltage of the GTO thyristor 1 is higher than the voltage of preset detection level, a control signal source 7 generates a control signal with a detection signal from a comparing and detecting means, a switch means is turned on with the control signal, and a gate current supply source 2 operates to supply a gate current to the gate of the GTO thyristor, which is in an on state continuously. When, however, the GTO thyristor is in the on state continuously and the anode voltage drops below the detection level, the detection signal from the comparing and detecting means is ceased, the control signal source 7 stops the operation, and the switch means turns off to stop the operation of the gate current supply source 2, so that the gate current is not supplied to the gate of the GTO thyristor any more. Consequently, the gate driving circuit of small power consumption for the GTO thyristor is obtained.

That is, illumination light diffused from the leading end of the light guide 12 and one laser beam as distance measuring laser beam are emitted. Therefore, the irradiation position of laser beam in an image is different corresponding to a distance. By this fact, distance information is obtained from the interval to the irradiation position measured from one end of the diameter of the image.

Abstract: PROBLEM TO BE SOLVED: To effectively transmit torque by supporting shaft directional reaction generated between respective balls and a groove of a disk plate in the vicinity or on its outside of a diameter of a crest of the groove continuously arranged in the circumferential direction of the disk plate. SOLUTION: A support center diameter D1 of shaft directional reaction generated between respective balls 5 and a groove 3a of a disk plate 3, is set in the same as a diameter D2 of a crest of the groove 3a continuously arranged in the circumferential direction of the disk plate 3.
