Title: Film feeder
Inventor: OKITSU KATSUHIKO
IPC: G03B21/44
Filed: 1989-06-29
Abstract: PURPOSE:To prevent a film from carelessly rewinding after it is automatically loaded by carrying out an automatic loading action regardless of the set condition of a film operating part. CONSTITUTION:A roll film cartridge 1 housing a micro-film F is loaded to a rewinding shaft 2a. Then, when the switch 12 of an operation panel 10 is pushed, the automatic loading is started. After the automatic loading is completed, the control knob 13 of the operation panel 10 sets the feeding direction and feeding quantity of the film, and a normal retrieving operation is started with the aid of a set signal. If the knob 13 is in a rewinding direction after the automatic loading is completed, a circuit 20 ignores the film rewinding signal of the knob 13. Consequently, careless rewinding after the automatic loading is completed is prevented. The knob 13 is operated in a neutral direction or the take-up direction of the film, so that the rewinding signal generated after the operation is validated. Then, when the knob 13 is switched in the rewinding direction after the film F is completely retrieved, the film F is rewound to a rewind reel 2 from a take-up reel 3.

Filed: 1979-12-20
Abstract: PURPOSE: To prevent an electric motor vehicle from occurring an abrupt shock by generating a reference voltage slightly increasing or decreasing the output voltage at the movable terminal of an accelerator resistor when the accelerator is fully opened responsive to the heated state of a chopper circuit.  
     CONSTITUTION: If the temperature of a chopper circuit 13 is in an ordinary state, since the resistance value of a thermistor is low, the potential at the point A is higher than that at the point B. When the operating amount of an accelerator is increased, the potential of the movable terminal C is raised, and the duty cycle of the chopper circuit 13 is increased. If the accelerator is fully opened, a transistor 18 is conducted on, and a bypass contactor 15 is closed. If the temperature of the chopper circuit 13 is raised, the resistance value of the thermistor 2 is increased, and the potential at the point A becomes lower than that at the point A. Thus, the duty cycle becomes lower, and the closure of the bypass contactor 15 is prevented.
