Title: Attraction release system for magnetic disk device
Inventor: HASHIMOTO SHUICHI
IPC: G11B21/21
Filed: 1988-12-24
Abstract: PURPOSE:To smooth the rising and falling of attraction and release, to set a proper characteristic and to attain sure release of attraction by switching a current in multi-stage. CONSTITUTION:A switch SW 60 of an attraction release circuit is turned on when a signal Vc of an MPU 7 is set and a current flows to a summing amplifier 41 from a power supply -VEE. A SW 63 is turned on by a signal GCS and the amplifier 41 causes a current (i) to flow at a low gain. The MPU 7 brings the signal GCS to logical H after a time t1 sec to turn off the SW 63, the amplifier has a high gain and a current i2 > i1 flows. Moreover, the signal GCS goes to logical L after a time t2 sec, the SW 63 is turned on to connect a gain resistor 62, the amplifier 41 goes to a low gain and the current of the amplifier 41 restores to the current i1. Moreover, after a time t3 sec, the signal GCS goes to logical L, the SW 63 is turned on, the gain resistor 62 is connected, the amplifier 41 has a low gain and the amplifier current restores to i1. Furthermore, the signal Vc is turned off to interrupt the supply of power supply -VEE. Through the constitution above, since no capacitance is in use, a desired attraction release characteristic is set and the dispersion in the attraction release characteristic is prevented.

Title: Motor drive camera
Inventor: NAKANO YOSHIYUKI
IPC: A23G9/04
Filed: 1989-12-19
Abstract: PURPOSE:To freely adjust the quantity of a film wound around a spool by driving the spool at the time of opening a rear cover of a camera. CONSTITUTION:When a push button for manual operation of shutter release is depressed, a half-depression switch SW13 is turned on. An operation signal indicating that the button 100 is operated is generated by the switch SW13 in accordance with this turning-on. A rear cover open/close switch SW12 detected the open state of the camera rear cover to generate an open signal. When receiving the operation signal and the open signal together, an exposure control part 604 permits power supply to a motor 600 to start driving of a spool 29. When the operation signal is lost during driving of the spool 29, power supply to the motor 600 is stopped. Since the spool is driven by the operation of the push button for manual operation during opening of the rear cover of the camera, a user can freely adjust the quantity of the film wound around the spool.
