Title: Power factor improving circuit
Inventor: NISHIMURA NAOKI
IPC: H02J3/18
Filed: 1996-07-16
Abstract: PROBLEM TO BE SOLVED: To obtain a desired output voltage with small-sized electric and electronic elements by comprising a PWM control circuit of a peak voltage detecting circuit, a subtracting circuit, a comparator circuit, a PWM oscillation circuit, and a driving circuit. SOLUTION: The voltage from an AC power source E1 is divided by means of voltage dividing resistors R4 and R5 after the voltage is rectified by means of a rectifier DS, and an operational amplifier IC1, a diode D2, and a capacitor C2 detect and hold the peak voltage, but the value of the detected peak voltage becomes proportional to the peak voltage of the power source E1. The peak voltage is outputted to a subtracting circuit 20 as a reference peak voltage, and the circuit 20 performs subtraction on the voltage and outputs the subtracted result to a comparator circuit 30 which compares the subtracted result with the voltage of a reference voltage generating circuit 40.  When a boosted voltage is controlled so that the voltage can become constant, the relationship between the input voltage Vi and the final output voltage V0 of the power source E1 is fixed and, when the difference is made smaller, the withstand voltage of a poststage element can be maintained at the conventional value. In addition, the size and loss of a power factor improving circuit can be reduced, because the burdens to a choke coil L1 and a transistor Q1 can be reduced.

Title: System of applying resistance to apertured original card in copying machine
Inventor: KANAZAWA YUKIO
IPC: G03G15/22
Filed: 1981-12-22
Abstract: PURPOSE:To protect the edge of an apertured original card from damage, by making a  resistance roll of a material of low frictional resistance and by moving down and stopping the resistance roll and operating a right and left resistor in the final stage of resistance action. CONSTITUTION:When the front end of a card (a) is moved to the position A of a  sensor, a separating roller 2 is stopped and feed rollers 9 and a resistance roller 3 are  driven and a card hold-down member 4 is opened. When the front end of the card (a) is  moved to a position B, the resistance roller 3 is moved down so that the card is conveyed while being pinched between the roller and a platen 5. When the front end of the  card is moved to a position C, the roller 3 is moved up and a right and left resistor 8  is operated. After that, the roller 3 is moved down and stopped and the card hold-down  member 4 is closed to hold the card (a) down. Because of the first resistance action in  the front-to-rear direction before the operation of the right and left resistor 8, the card  (a) is stipped upstream to a stopper so that the card is protected from damage. The roller 3 is not rotated in the second half of its descent during the second resistance action in the front-to-rear direction, so that the card (a) and the roller slip relative to  each other. Since the friction on the roller 3 is low, the card (a) is not damaged.
