Title: Oscillation circuit
Inventor: FUJITA KOICHI
IPC: H03B5/32
Filed: 1987-01-14
Abstract: PURPOSE:To prevent the peak value of the input voltage of an amplifier circuit from being increased than a value at the time of performing an oscillation operation after quenching, by performing the quenching by electrical disconnection between a feedback circuit and the output part of the amplifier circuit. CONSTITUTION:When a control signal S is set at an H level, the oscillation operation is performed by energizing a transfer gate 6. When the control signal S is set at an L level, the transfer gate 6 is de-energized, and a resistor 5 and a resonance circuit 5 are disconnected from the output part 3 of a NAND gate 1. Therefore, no resonator 2 can keep oscillation, then, starts attenuating motion. Electric charge accumulated in resonance capacitors C1 and C2 are discharged according to leak resistance and the time constants of the C1 and C2, and the input voltage of the NAND gate 1 performs the attenuating motion centering nearly the level of an operating point before the quenching.

Title: Method for setting piercing time
Inventor: YAMAZAKI ETSUO
IPC: B23K26/382
Filed: 1990-01-16
Abstract: PURPOSE:To allow the setting of exact piercing time with a simple operation by shortening or extending the piercing time which is previously commanded by a processing program by means of an operating switch. CONSTITUTION:Piercing ends when an operator first pushes a shortening switch to send a shortening signal PTS to a timing control circuit 35 during piercing. On the other hand, the piercing time is extended while an extension signal PTE is effective when the operator pushes an extension switch to send the extension signal PTE to the timing control circuit 35 during the piercing. The timing control circuit 35 sends a control signal to an output gate 32 to control the output and to determine the piercing time. The shortened or extended piercing time is measured by a measuring circuit 36 and is substd. with the piercing time commanded by a holding circuit 34. The time held in the holding circuit 34 is effective as the piercing time of this time. The exact piercing time coinciding with the actual piercing time is set in this way.

Abstract: PURPOSE:To suppress noise at the time of starting a device by blocking holding current supply to a step motor at the time of driving thereof even in such a case where a power transmission system is driven through the step motor. CONSTITUTION:A rated voltage supply transistor 6 and a predrive current supply transistor 4 for switching voltages to be applied on the exciting coils 2A, 2B, 2a, 2b of a step motor 1 are provided.

Consequently, the step motor 1 rotates with low torque and gears in a power transmission system driven through the step motor 1 also rotate. At that time, even if there is a gap between a pair of mating gears, the gears make pressure contact slowly without producing noise. Subsequently, the transistor 6 is turned ON to apply a rated voltage onto the exciting coils 2A, 2B, 2a thus rotating the step motor normally.
