Title: Treatment of electrophotographic receptor
Inventor: NOMURA ICHIROU
IPC: G03G5/02
Filed: 1981-09-18
Abstract: PURPOSE:To prevent the failure of a photoreceptor in the stage of giving electrostatic charging hysteresis to the photoreceptor of three-layered constitution having an insulation layer by application of an AC voltage thereto by making the voltage of the polarity at which majority carriers are implanted lower than the voltage of a reverse polarity. CONSTITUTION:A conductive rubber roller 2 for application of voltage is  brought into press contact under suitable pressure with an electrophotosensitive drum 1 of the three-layered constitution wherein a photoconductive layer is provided on a conductive substrate and an insulating layer is provided thereon. A driving motor 4 is operated and a high voltage transformer 3 is operated to apply a high voltage to the drum 1 in the absence of light irradiation, whereby the drum is subjected to an electrostatic charging hysteresis treatment. Of the AC voltage used in the treatment, the voltage of the polarity at which the majority carriers of the photosensitive layer are implanted is made lower than the voltage of a reverse polarity. Thus excellent photosensitive characteristics are provided to the drum 1 without failure, etc. of the insulation layer.

Filed: 1990-06-05
Abstract: PURPOSE:To increase the quantity of light emission of a light emission part and to improve the dust detection accuracy by providing a switching part which operates with the output of an oscillation part and switching the light emission part and a light reception part through the switching part. CONSTITUTION:The oscillation part 12 uses a timer IC 13 to give operation cycles of the switching part 11, so the light emission part 1 and light reception part 2 turn ON and OFF repeatedly. The light emission part 1 can be increased in flowing current value according to the duty ratio of ON-OFF driving. For example, when the duty ratio is 50%, a current which is twice as large as before can flow. Consequently, the quantity of light emission of the light emission part 1 increases to prevent malfunction due to external light. Then whether or not there is dust can be detected with the output of the light reception part 2 when the light emission part 1 and light reception part 2 are driven. When the light emission part 1 and light reception part 2 are both OFF, input data (output of the light reception part 2 passed through an amplification part 6 and a comparator 7) to a microprocessor muP8 is ineffective and the muP8 decides that the same data is inputted until dust data is inverted to control a fan motor 9.

Title: Demagnetizing device
Inventor: KASAHARA MIZUHO
IPC: H01F13/00
Filed: 1979-11-17
Abstract: PURPOSE:To generate a good stable and gradually decreasing magnetic field for demagnetization by digitally performing thyristor phase control. CONSTITUTION:Clock signals (c) in a clock oscillator 1 oscillating by splitting the half period of a commercial power source are supplied to a presetting counter 2. A single multiplier 4 generates presetting pulses (b) through a pulse forming circuit 5  to supply the pulses to a counter 7. Next, the counter 7 generates firing signals (d)  by counting the predetermined number of the clodk signals (c). The latter edge of  the signal (d) becomes firing pulses. And the predetermined number of the clocks  counting by the counter 7 increases by the contents of the binary counter 7 every  half period of the power source. Therefore, the firing signals (d) change every half  period and a coil current e decreases by the amount of a flow angle corresponding  to the pulse intervals of the clock signals (c). As a result, a stable and gradually decreasing magnetic field for demagnetization will be generated.
