Title: System for detecting interference wave
Inventor: TAKAMATSU KOJI
IPC: H04B17/345
Filed: 1985-02-27
Abstract: PURPOSE:To attain correct decision of talking quality of a talking channel by providing a limiter circuit so as to suppress the noise level to a prescribed level thereby decreasing the deviation of detection level of beat and preventing malfunction of an interference wave detecting circuit. CONSTITUTION:An intermediate wave input signal from a receiver of a radio telephone set decision the level of talking quality is subject to elimination of a signal being at a prescried level or over by a limiter circuit 10 so as not to be inputted to a high level signal to an amplifier 11. The level set to the limiter circuit 10 is set to a level having a sufficiently small noise and at which the talking quality is deteriorated by a disturbance signal only. The peak level of the noise included in the signal amplified by the amplifier 11 is a level allowing a comparator 13 to output a high level sufficiently tentatively but when the signal is rectified by a rectifier circuit 12 because of noise spike, the voltage becomes an output lowered than the reference voltage at the comparator 13. Thus, even when the input electric field of the receiver is lowered, the level of beat generated depending on the difference between a desired wave and a disturbing wave is not apparently increased.

Title: Controlling device for electric motor vehicle
Inventor: KURIYAMA SHIGERU
IPC: B60L7/02
Filed: 1981-03-18
Abstract: PURPOSE:To prevent an electric motor vehicle from sliding down at its climbing time by increasing a current value to the prescribed current flow rate when a plugging occurs without switching a forward/reverse contactor. CONSTITUTION:The output from an accelerator 12 is supplied through a resistor R, a primary delay circuit of a capacitor C and a transistor TR1 to a current flow rate controlling circuit 13 of a chopper circuit 8. When a forward switch FSW is shifted to a reverse switch SW or vice versa, clock pulses are outputted from a flip-flop FF1 and an exclusive-OR circuit EX.OR and the voltage of a capacitor C3 is high level at this time. Accordingly, the output Q of a flip-flop FF2 becomes high level. A proportional controlling circuit C supplies the deviation between the output Q of the flip-flop FF2 and the output of a current flow rate detector A to a transistor TR2, thereby increasing the motor current.
