Title: Waveform shaping circuit for inverter
Inventor: TAKIGAWA SUMIO
IPC: H02M7/538
Filed: 1984-10-03
Abstract: PURPOSE:To prevent a transistor from flowing a shortcircuiting current by alternately providing a pause period when push-pull transistors are turned on and off, and shortcircuiting between the terminals of a main transformer in the period. CONSTITUTION:A main push-pull transistor switch 15 turns a DC power source 17 on and off to obtain an AC output from the secondary side of a main transformer 16. This switch 15 is driven by pulses f13, f14 passing from a double frequency oscillator 1 through a pulse width generator 2, a 1/2 frequency divider 8, NAND circuits 9, 10, differentiators 11, 12 and flip-flops 13, 14, and controlled by a constant-voltage controller of a comparison voltage circuit 22, an error amplifier 23, and a photocoupler 25. In this case, an anti-inductance switching transistor 19 is provided to shortcircuit the primary side of the transformer 16. This shortcircuiting period is a pause period between the on and off of the switch 15 to shortcircuit the induction current of the transformer 16, thereby shaping the output waveform.

Title: Copying machine
Inventor: KUSUDA TATSUFUMI
IPC: G03G15/04
Filed: 1981-12-28
Abstract: PURPOSE:To simplify the constitution of a titled machine and to reduce its size by allowing an overrun prevention detecting means for an optical system to serve also as an origin position detecting means. CONSTITUTION:With a copy button depressed, a driving motor starts revolving and once the position detecting means confirms that the optical system 2 is at an original position, the revolution of the motor is transmitted through a clutch  to a pulley 23, so that the optical system 2 starts moving forth through a wire  24, pulleys 20 and 21, and a wire 22. At this time, a disk also starts revolving and then the number of pulses outputted from an encoder synchronizing with the motor is counted. If the output of a photosensor 26 does not turn on even a specific time later, it is decided that the optical system is abnormal. In a copying cycle, a size detecting means detects the size of recording paper and the optical system 2 moves by the distance corresponding to the detected size; and then the clutch is turned off to stop the movement of the optical system 2, which is returned to the original position through the reversing of the motor, the shifting of gear trains of the driving system, or mechanical force.
