Title: Timing extraction circuit
Inventor: TAKAHASHI SATOSHI
IPC: H04L7/027
Filed: 1992-02-13
Abstract: PURPOSE:To prevent phase characteristic from deteriorating even when the Q value of a timing extraction filter is set at a high value by compensating the phase characteristic of the timing extraction filter by the linear phase characteristic of an amplitude limiting circuit. CONSTITUTION:The timing extraction filter 3 extracts a clock signal from the differential signal of a reception signal outputted from a differential rectifier circuit 2. The clock signal, after whose amplitude being adjusted by the amplitude limiting circuit 4, is supplied to an identification device 1 as the clock signal. The identification device 1 latches or outputs the input signal according to the clock signal, thus, an electrical signal in accordance with the input signal can be reproduced. In such a case, since the amplitude limiting circuit 4 provided at the rear stage of the timing extraction filter 3 is provided with the phase characteristic so as to offset the linear phase characteristic in the neighborhood of the center frequency of the timing extraction filter 3, the phase characteristic of the timing extraction filter 3 can be completely offset, or at least, the increment of it can be reduced.

Inventor: MARUYAMA JIYUICHI
IPC: G01B11/25
Filed: 1980-05-07
Abstract: PURPOSE:To detect shapes of various bodies with simple and inexpensive constitution by detecting continuously the position of a spotlight, scanning on an objective body in a constant direction, in the scanning direction and perpendicular direction. CONSTITUTION:A parallel beam from light source 11, such as a laser, is reflected by fixed mirror 12 and rotary mirror 13 to scan on objective body 1 in direction X. The reflected light forms an image on light position sensor 16 via lens 15. Light position sensor 16 converts the position of the light into electric signals with respect to directions X and Y2. For the detection of V-shaped groove 1a, for example, peak- value timing detecting circuit 20 detects the timing of the generation of the peak signal of signal Y and drives sample holding circuit 21, which receives signal X as an input, to fetch and output X-directional position X0 of V-shaped groove 1a. This operation is repeated for every scan to detect position X0 of the V-shaped groove continuously. Thus, shapes of various bodies are detected with the simple and inexpensive constitution.
