Filed: 1988-08-29
Abstract: PURPOSE:To lessen effectively the front wheel lock by providing an air flow variable means for varying the front brake operating air flow according to the slidableness of the road surface between a front brake valve and a front brake means. CONSTITUTION:An air flow variable means 20 is provided between a front brake valve 14 and a front brake means 12.

Title: Signal detecting device
Inventor: OSAWA TOSHIFUMI
IPC: G01J1/44
Filed: 1984-10-11
Abstract: PURPOSE:To prevent saturation of circuit output by a DC current and to reduce an amplification factor of noise by providing a diode and an amplifier in a feedback path in a device for detecting a signal from an optical signal source modulated to the prescribed frequency. CONSTITUTION:A sensor PD photodetects lights of signal light added with external light and an optical electric current (ip) is flowed to actuate an operation amplifier OP1. Then, the signal from the operational amplifier OP1 is inputted to an amplifier 1 providing resistance 7 in the feedback path. Then, the output is impressed on the operational amplifier OP1 via the diode D1. Consequently, since the diode is used in the feedback circuit for low-pass cut, an impossibility of signal detection due to the saturation of the output is prevented by enlarging compressibility of a DC component in case the DC current of the external light is large, and the amplification factor of the noise occurring from a feedback loop can be reduced, in case the DC electric current of the external light is small.

Inventor: KASAI JUNICHI
IPC: B60R11/02
Filed: 1984-10-11
Abstract: PURPOSE:To produce acoustic signals balanced for all noises capable of affecting a reproduced sound by detecting a noise level at each prescribed frequency and controlling the acoustic signal at each frequency corresponding to the noise level. CONSTITUTION:The noise inputted from a microphone 12 is inputted to a frequency analysis circuit 14 via a noise detection circuit 13, analyzed into a band of each center frequency the same as that of a channel divider 5, noise level signals A-F at each center frequency band are detected by a noise level detection circuit 15 and level half-reduction signals a-f at each center frequency are detected by a level half-reduction circuit. Since it is discriminated that the noise of a center frequency band affects the reproduced sound in the range of 2 octaves, the well-balanced forward characteristic is attained by inputting a value obtained by the noise level detection circuit and a value halved with respect to upper/lower octave obtained by the level half-reduction circuit to dynamic range controllers 6A-6F.
