Title: Oscillatory wave motor drive circuit
Inventor: ATSUTA AKIO
IPC: H02N2/00
Filed: 1993-06-24
Abstract: PURPOSE:To provide a drive circuit which can detect resonance state with a simple circuit configuration accurately. CONSTITUTION:In a drive circuit of transformer drive type consisting of a rectifier 9, an A/D converter 10, a microcomputer 11, a variable frequency oscillator 2, a phase shifter 3, switching circuits 4 and 5 for generating pulses, drive electrodes 1a and 1b of a motor etc., the natural electrostatic capacity of an vibration wave motor and the inductance of the secondary winding of a transformer constitute a parallel LC circuit so that the LC parallel circuit also turns into an electrically resonated state when the vibrator of the motor turns into a mechanically resonated state, the circuit impedance is minimized, and hence the output voltage of the secondary winding of the transformer is extremely reduced. A voltage-divider circuit consisting of resistors R2 and R3 is connected in parallel to the secondary winding of a transformer 6 to detect that the vibrator (an excitation element 1 is shown) of the vibration wave motor turns into a resonated state.

Title: Electrostatic recording device which has obviated out-of-focus image caused by paper powder
Inventor: KOSEKI YASUFUMI
IPC: G03G15/043
Filed: 1986-07-02
Abstract: PURPOSE:To effectively eliminate paper powder, and to prevent an out-of-focus image by constituting the titled device so that a mode in which an erasing lamp is turned off and a toner is made to adhere to the outside of an image forming area, and a mode in which the lamp is turned on and the toner is not made to adhere can be selected. CONSTITUTION:An erasing lamp 22 is usually controlled by such a lighting pattern as only a part of width l1 is turned off, other part is turned on and charge for a patch image is left in a part A, and also, width l2 is turned off, other part is turned on and charge is left in a part B corresponding to transfer paper. On the other hand, in only parts C, D of widths l3, l4 of both side parts of the part B and a part E corresponding to width l5 corresponding to length in the axial direction of a feed paper roller, the erasing lamp 22 is turned off so that charge is left. As a result, when a photosensitive drum 9 is developed, a toner is attracted to the parts C, D and E, and the toner reaches a cleaning device as it is and scraped down by a blade. In this way, data of both these patterns are stored in the same ROM30 so that a usual pattern and a pattern for eliminating paper powder can be selected freely.

Filed: 1985-07-15
Abstract: PURPOSE:To improve an operation rate by setting a specific count setting value when an occupied instruction is receiver from other transmitter from the 1st transmission means and outputting a forced release instruction to the 1st transmission means when the occupied release instruction is not received until the time count operation is finished. CONSTITUTION:When a reserve instruction from other station is detected from the 1st transmission line 11, the 2nd line occupancy flag in a RAM in a CPU 15 is set and a timer value calculated based on the own node address obtained from the own node address setting section 10 is set to a timer section 18. On the other hand, the other station outputting the reserve instruction cannot output succeedingly the release instruction because of a fault and the supervisory time is over, the release instruction is outputted forcibly via the 1st transmission line 11 in order to release the inadequate occupancy state of the 2nd transmission line 12. Thus, even when the station occupying the 2nd transmission line 12 is failed, the state that the transmission line is occupied inadequately is avoided and the operation rate is improved.
