Filed: 1983-11-16
Abstract: PURPOSE:To obtain stable pictures of good quality for a long time by providing a means, which charges electrostatically the surface of an insulating elastic cleaning roll, and a pre-electrifier in the upstream side of the roll. CONSTITUTION:Triboelectrification occurs by contacting between an insulating elastic cleaning roll 9 and a scraper 10, and the surface potential of the roll 9 has a polarity opposite to that of a toner, and the roller 9 is pressed and rubbed to a photosensitive body 1. A pre-electrifier 8 is provided for the photosensitive body 1 in the upstream side of the roll 9 to give electric charge having a polarity opposite to that of the surface potential of the roll 9 to the remaining toner on the photosensitive body. Consequently, not only the remaining toner but also foreign matters such as paper and corona products stuck strongly to the photosensitive body 1 are removed surely, and stable pictures of good quality are obtained for a long time.

Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To provide the musical tone generating device which can perform smooth pitch control with simple constitution without increasing the circuit scale. SOLUTION: At the time of transition from a 1st pitch to a 2nd pitch, a delay circuit 4 generates a 1st delay time corresponding to the 1st pitch and a 2nd delay time corresponding to the 2nd pitch according to mutually different read addresses (a) and (b) and performs delay interpolation from the 1st delay time to the 2nd delay time with an interpolation coefficient (r) which varies with a portamento rate at the time of the pitch transition, so the pitch transition becomes smooth. Further, the delay interpolation obtained only by multiplication and addition, so the control can be done with the simple constitution without increasing the circuit scale like before.

Title: Discharge lamp lighting device and its lighting method
Inventor: ITO HIDEKI
IPC: H05B41/231
Filed: 1993-08-31
Abstract: PURPOSE:To start a discharge lamp without requiring enlargement of high voltage pulses by actuating a high voltage pulse forced stopping means upon a delay 10mus or more from sensing of a lamp current by a lighting sensing means. CONSTITUTION:When a discharge lamp 13 is lighted and a lighting sensing circuit 17 senses that a lamp current flows via a sensing winding 16, a light emitting diode PD1 emits light 10mus thru 20ms after the lamp current is sensed. Because a photo-thyristor PSCR1 is turned on upon receiving the light emission, the condition a resistor R3 and capacitor C2 are short-circuited is generated, and a gate trigger element 16 is turned off. Therefore, a bidirectional thyristor 15 is maintained in the off state, and generation of high voltage pulses is prohibited after lighting. This enables movement of the lamp even without requiring enlargement of the pulse voltage from a high voltage pulse generating circuit 14, and sputters after the lamp is started are prevented, and also dielectric destruction of the ballast can be precluded.
