IPC: H03J7/28
Filed: 1980-05-19
Abstract: PURPOSE:To perform stable frequency detection with high resolution by detecting an IF digitally and by using a reference frequency signal in a synthesizer circuit as a reference signal for said frequency detection. CONSTITUTION:A frequency-division code outputted from a channel-selection control circuit 12 is supplied to a variable frequency-dividing circuit 7 and the oscillation frequency of a voltage-controlled oscillator 5 is decided by its frequency-division ratio. An IF signal, on the other hand, is inputted to a frequency detector 13 and one frequency-divided signal from a frequency divider 11 is used as a reference signal to detect whether it is at a prescribed frequency or not. The detection result of the detector 13 is inputted to the channel-selection control circuit 12 and used, for example, as a sweep stop signal for automatic tuning. As the detection reference signal of this detector 13, the frequency-divided signal of a frequency synthesizing circuit composed of a variable frequency divider 7, a phase comparator 8, an LPF9, a reference frequency oscillator 10, and the reference frequency divider 11 is used to perform high-resolution and stable tuning detection.

Filed: 1988-03-19
Abstract: PURPOSE:To detect the projection state of the road surface at low cost with simple constitution by deciding the projection state of the road surface when the distance signal and photodetection quantity signal of a reflected light vary at the same time at the time of irradiating the road surface with a directional beam. CONSTITUTION:The directional beam La is projected on the road surface 3 in front of a vehicle body and its reflected light Lb is received by a trigonometric survey device 4 to obtain the distance signal (f) from a distance arithmetic circuit 14 and the photodetection quantity signal (e) from a photodetection quantity arithmetic circuit 13. Then when both signals vary at the same time, it is decided that the road surface 3 has the projection. Namely, signals (g) and (h) of variation are detected by differentiating circuits 15 and 16 respectively and decision circuits 17 and 18 output decision signals (i) and (j) when their values exceed a specific value, so that a projection decision circuit 19 decides the projection shape. Thus, the projection state of the road surface 3 is securely detected at low cost with the simple constitution.
