Title: Method for confirming actuator lock
Inventor: SASAMOTO TATSURO
IPC: G11B21/22
Filed: 1988-12-21
Abstract: PURPOSE:To improve the reliability by confirming whether or not a lock mechanism is in normal operation by a position signal. CONSTITUTION:When a command of stopping the drive of a disk 11 is issued from a host device, a microprocessor (MPU) 13 returns at first an actuator 14 to a landing zone while driving the disk 11 to operate a lock mechanism 18. Then the MPU 13 is going to move the actuator 14 at the outside of the landing zone. The MPU 13 checks a position signal from a position detection circuit 17 connecting to a head 16 and since the position signal is changed, it is discriminated that the lock mechanism 18 is not in normal operation, the MPU 13 returns the actuator 14 again to the landing zone and operates the lock mechanism 18 or gives a fault report to the host device.

Filed: 1995-11-06
Abstract: PROBLEM TO BE SOLVED: To stop an engine with one sensor sensing when running operation is conducted by fitting respective sensors at respective positions on a vehicle so that they may sense without stopping the engine although the respective sensors conducts sensing in trying to leave a driver's seat with the engine starting or kept in a running condition. SOLUTION: When the engine 6 of a vehicle is started, an engine starter sensor 1 senses, a signal is inputted into an input circuit 4. At the time of running operation, a running sensor 3 senses, and a signal is inputted in the input circuit 4 to stop the engine 6. When a driver tries to leave his/her seat with the engine 6 kept in a running condition, a driver's seat sensor 2 senses, and a signal is inputted into the input circuit 4. When the driver returns to his/her seat and takes running operation, the running sensor 3 senses, and a signal is inputted into the input circuit 4 to stop the engine 6. To run the vehicle, the storage of the input circuit 4 is deleted only by a clear switch 7. It is thus possible to run the vehicle without stopping the engine 6.

Filed: 1990-11-26
Abstract: PURPOSE:To facilitate setting of a magnification and a density and to reduce electric power consumption, by judging if image forming action is being performed or not, and controlling driving of back light means based on the result thereof. CONSTITUTION:When an operator sets a magnification or a density with a magnification key or a density device, a judging means 271 judges that copying action is not performed because, for example, the lamp of an optical system 2 has not been turned on. Based on this judgment, a control means 272 turns on a switch 25 to turn on a cold cathode-tube 191, which brightens a liquid crystal plate 19. When copying starts and the lamp of the optical system 2 is turn on, the judging means 271 judges that copying is being performed, and the control means 272 turns off the switch 25, making the cold cathode-tube 191 turned off. This improves the visual recognition of an information display portion and, furthermore, reduces electric power consumption.
