Title: System for digitizing multiphase signal
Inventor: HASEGAWA SUSUMU
IPC: G11B21/10
Filed: 1986-11-27
Abstract: PURPOSE:To form a digital positional signal with high accuracy by providing a timing adjusting circuit adjusting a control timing signal for a switching circuit and using the output of the timing adjustment circuit so as to avoid A/D conversion at the discontinuous point of a head positional signal. CONSTITUTION:In giving a timing signal sw1 to the data terminal D of a D flip-flop circuit (DFF)10 and the output waveform (e) of an AND circuit 9 to a clock terminal C, the output waveform sw1 is obtained from a terminal Q by the logic operation of the DFF 10. The period of A/D conversion is avoided even by using a waveform (a) in place of the waveform (e) as the input to the terminal C of the DFF 10 in principle. Since the waveform error is, however, larger, the error is halved by utilizing the waveform (e). As a result, a state logic signal (a) representing the converting state of an A/D converter is subjected to A/D conversion, the switching of the timing signal sw1 controlling a switching circuit 1 is not conducted. Thus, the input signal waveform is changed into F' in place of the waveform F and only the continuous signal exists.

Title: On-vehicle laser radar apparatus
Inventor: ASAMI HIDEO
IPC: G01S17/88
Filed: 1991-10-30
Abstract: PURPOSE:To lengthen a life of a laser diode to improve durability and safety of an apparatus by providing a laser intensity changing means to change intensity of laser light according to the traveling speed of an automobile. CONSTITUTION:A laser outputting means 1 emits laser light in pulses frontward. A light receiving means 2 receives reflected light on a front obstacle. An arithmetic means 3 calculates the distance to the preceding obstacle from time difference at a time point of laser light emission and at a time point of reflected light reception. An automobile sensor 4 measures the traveling speed of an automobile and a laser intensity changing means 5 changes intensity of the emitted laser light accordingly. It is not necessary to detect the distance to a distant object during low speed driving. That is, a measurement range may be short during the low speed driving and the laser light intensity may be small. By reducing the laser light intensity only during the low speed driving, a life of a laser diode is shortened accordingly, thereby improving durability of an apparatus while small intensity of the laser light during the low speed driving is safe.
