Inventor: YOSHIDA KEIICHIROU
IPC: B21H8/00
Filed: 1984-05-25
Abstract: PURPOSE:To roll rationally and intermittently a blank tape by eliminating the pressurizing force on the blank tape in the central part thereof in the stage of moving back and forth a rolling roller perpendicularly to the advancing direction of the tape and forming a projecting line. CONSTITUTION:The blank tape 2 having a rectangular section is imposed on an anvil 1 and a roller block 5 having a groove 4 of a prescribed width and depth is fixed to the bottom side of the rolling roller 3. Grooves 2a, 2b are preliminarily provided to the tape 2 by maintaining the same space as the width of the projecting part 6a of a product tape 6 therebetween. The roller 3 is rolled back and forth to form the projecting part 6a by the groove 4 to the tape 2 on the anvil 1. The roller 3 is slightly lifted via a spring 10 by a backup roll 9 in contact with the plane part 8 on the top side of the roller 3 and a clearance is produced between the roller 3 and the tape 2 when the roller 3 faces the central part of the tape 2.

Filed: 1979-08-20
Abstract: PURPOSE:To enable opening and closing of a vacuum switch in a prescribed number of times for unidirectional revolution of an output shaft of an on-load tap changer by so constructing it that a revolving lever may execute reciprocatory rotations in a prescribed number of times for unidirectional revolving motion of an energy storing mechanism. CONSTITUTION:When the output shaft 1 of an energy storing mechanism rotates in one direction, a roller 23 urged by a cam 2 moves rightwardly in the figure, a revolving lever 20 rotates counterclockwise, an arm 21A is moved downwardly and an arm 21B is moved upwardly. In this manner, a connector 11B moves upwardly, and a movable electrode 10B accordingly moves upwardly, so that a vacuum switch B is closed by its vacuum self-closing force. On the other hand, a vacuum switch A retains in closed state. When the shaft 1 is further rotated in the same direction, the arm 21A urges the connector 11A to open the switch A. In this manner a make-before break function is imparted to the opening and closing sequence of the switches A, B. Further, when the cam 2 is so formed that the roller 23 executes reciprocatory motion for the revolution of the shaft 1, it can open and close the vacuum switches in a prescribed number of times.

Filed: 1981-07-07
Abstract: PURPOSE:To prevent waste of an unnecessary current, by starting an operation of an electronic timer, when the first stroke of a release button has been continously pushed for a prescribec time. CONSTITUTION:When a switch 12 is closed by the first stroke of a release button, feed is executed to a photometric circuit 4, an operating circuit 5, a displaying circuit 6, etc. through a transistor 2. Subsequently, when an electronic timer 3 is used, a timer setting switch 20 is closed. In this state, when the first stroke is continuously pushed for a prescribed time, for instance, 0.1 second or longer, the timing circuit 3 detects it and starts its time counting operation.
