IPC: E05F15/56
Filed: 1993-03-04
Abstract: PURPOSE:To provide an automatic opening/closing device for the optimum deceleration when a vehicle door is closed. CONSTITUTION:As for an opening/closing device for opening and closing a door in the verital direction by an opening/closing mechanism which is extended and contracted by a hydraulic pressure, when a switch is operated to 'closure' where the door is to be closed, the deceleration starting position of the door is set according to the opening degree (closing operation starting position) of the door (110, S200-S230). The deceleration starting position is set at the position close to the perfect opened position as the closing operation starting position is closer to the perfect opened state of the door. The door is closing-operated by driving a motor in the direction of the discharge of oil from the opening/ closing mechanism (S240), and when the door is closed up to the deceleration starting position set at that time, the door is decelerated by restricting the flow rate of oil (S270, S280). Accordingly, the door is decelerated in a stable manner without being given with the influence of the door closing operation starting position, i.e., the inertial force of the door, and can be closed in safe.

Abstract: PURPOSE: To make it possible to obtain a printer of extremely superior print quality by eliminating influences of the jitters by counting type pulses as many as an even number and then by correcting power frequency fluctuation.  
     CONSTITUTION: Once a printer is driven, type pulses are generated and transferred to type-pulse number counter 20, correcting-pulse counter 21, and correcting-time setting counter 24. At this time, nominal-value setting timer 22 is set by the output of counter 21 and after the set value of timer 22, counter 21 is cleared. Then, counter 21 counts the time when counter 20 counts type pulses as many as 160, for example, and this value is entered in register 23. Counter 24, on the other hand, starts counting by a type pulse applied when this value is entered in register 23, thereby counting reference pulses CL 2 . Then when they are counted as many as the entry value of register 23, matching circuit 25 generates a signal, which is transferred to J-KFF26, thereby bringing magnet coil part 27 under control.
