Title: Device for electric power steering
Inventor: DEN TAKEKUNI
IPC: H02P6/24
Filed: 1991-04-02
Abstract: PURPOSE:To prevent a driver from feeling strange in steering a vehicle and the return of steering wheels from being delayed, when driving of a motor helping increase the steering force of the steering wheels is stopped. CONSTITUTION:An electric power steering includes a torque sensor 6 for detecting torque generated through the control of steering wheels, a control portion 12 to which the detection signal of the sensor 6 is input, power MOSFETs T1, T2, T3, T4, T5, T6 to which control signals output by the control portion 12 are input, the coils 8au, 8av, 8aw of the U-, V- and W-phases of a motor which have their one ends connected to the power MOSFETs T1, T2, T3, T4, T5, T6 and the other ends connected to one another, and a motor stop signal generating circuit 13 which outputs a stop signal SS when a dead zone arrival signal So output from the control portion 12 is input thereto. The power MOSFETs T1, T2, T3, T4, T5, T6 are commutation controlled and electricity is transmitted to each coil 8au, 8av, 8aw so that the motor is driven. When a torque signal ST arrives at a dead zone the control portion 12 outputs a dead zone arrival signal So, and the motor stop signal generating circuit 13 outputs a stop signal SS to turn off the power MOSFETs T1, T2, T3, T4, T5, T6 simultaneously: Current supply to each coil 8au, 8av, 8aw is thereby cut off and one end of each coil 8au, 8av, 8aw is separated and driving of the motor is stopped.

Title: Mobile telephone terminal unit with clearing processing function
Inventor: MARU TSUGIO
IPC: H04W88/02
Filed: 1988-04-20
Abstract: PURPOSE:To turn off a power source switch without causing a sense of incongruity although a clearing processing function at the time of the turning off of a power source during speech is provided by changing delay quantity until the power source is turned off for the cases during speaking and during waiting. CONSTITUTION:In the case of a waiting state, an adapter control part 7 outputs a control signal for shortening the delay quantity in a delay circuit 4 from a terminal 71. Thus, delay time is set to be comparatively short time. In the case of a speaking state, the adapter control part 7 outputs the control signal for setting the delay quantity in the delay circuit 4 to be the time until the clearing processing is completed from the terminal 71. Thus, the delay time is set to be the comparatively long time until the clearing processing by the time constants of a resistor R1 and a capacitor C is completed. Therefore, even if an operator pushes a push button again because the turn-off of a power source is not indicated immediately even if he pushes the push button for switching off the power source, the power source is prevented from being turned on.
