Title: On-vehicle range-finding device
Inventor: FUJIMORI NORIO
IPC: G01S17/93
Filed: 1993-12-02
Abstract: PURPOSE:To ensure safety for workers and for passersby when a vehicle is running under normal conditions. CONSTITUTION:A transmission means 1 includes a PLD(pulse laser diode) to transmit pulse beams whose output level can be varied. A reception means 2 receives the pulse beam (reflected pulse beam) transmitted from the transmission means 1 and reflected by a reflector. A distance measuring means 3 measures the distance to the reflector according to the transmitted and reflected pulse beams. An output control means 4 comprises an arithmetic unit 5 and an emission circuit 6. The arithmetic unit 5 computes the output level of the pulse beam to be transmitted from the transmission means 1, according to the distance to the reflector which is measured by the distance measuring means 3. The output level of the transmitted pulse beam is preset to be proportional to the distance so that, when the distance is zero, the level is low. The emission circuit 6 drives the transmission means 1 according to the output level of the transmitted pulse beam which is computed by the arithmetic unit 5.

Title: Stabilized electric power source apparatus for discharge lamp
Inventor: TATSUMI YUKIO
IPC: H05B41/282
Filed: 1994-11-11
Abstract: PURPOSE: To improve the lighting function of a discharge lamp immediately after lighting by supplying d.c. input to an inductance element at high intensity based on a start control signal immediately after lighting of the discharge lamp. CONSTITUTION: Though the lamp voltage VL becomes almost 0 immediately after lamp lighting, that the voltage of a connection point P3 lowers to near 0 is delayed by a capacitor C2. That is, the voltage of the connection point P3 is kept as high as the voltage VL before lighting. As a result, even after lighting, the condition before the lighting is retained immediately after lighting. Consequently, a Zener diode ZD1 is electrically conductive and a SW element Q2 is put in ON state and voltage of a connection point P2 becomes higher than that of a connection point P1 and rather than a stabilization control signal S1 from an IC 1, a start control signal S2 from an IC 2 is sent prior to a control circuit 5. In this way, the SR element Q1 is limited more by the current limiting level by the signal S2 which has a higher current limit level than current limiting level of the signal S1.

Filed: 1987-12-02
Abstract: PURPOSE:To lower shock sound generated by the collision with a stopper and to perform quiet printing operation, by supplying a braking signal imparting force in an advance direction to a printing wire to a drive part during the return operation of the printing wire. CONSTITUTION:When a printing wire 1 is performing return operation before stopped by a stopper 6, braking signals 41A, 41B are supplied to a drive part 21. These signals are ones for imparting force in an advance direction to the printing wire 1 and, during the return operation of the printing wire 1, the braking signals 41A, 41B simultaneously rise at first and the braking signal 41A rises precedingly. Thereafter, the braking signal 41B falls in predetermined timing. By this method, an exciting current having a waveform slightly small in the max. current value is supplied to the coil 10 of the drive part 21 and the return speed of the printing wire 1 is suddenly lowered. By this mechanism, the shock generated when an armature 4 collides with the stopper 6 is sufficiently relaxed.

Title: Minute defect detection method of recording medium
Inventor: ISHIKAWA TETSURO
IPC: G11B5/09
Filed: 1994-12-07
Abstract: PURPOSE: To hinder the reading of a fine level signal by lowering the sensitivity of a reproduction system which reads magnetic information on a recording medium to reproduce it as bit information when a specified inspection mode is indicated. CONSTITUTION: Magnetic information on a recording medium detected by a head IC1 is amplified by an amplifier 2 and after the removal of a noise component or the like with a filter 3, an equalization of a waveform is performed by a peak detector 4, which is allowed to change sensitivity following an envelop curve at two levels, high and low, with respect to a peak position. β1 and β2 in the drawing are sensitivity coefficients changeable with a switch 4a and the β1 is for the high sensitivity while β2 for the low sensitivity. When β1 is used, the envelop curve follows changes in the peak position quickly. For example, when the peak position of a signal becomes low, the envelop curve also lowers to the same extent and further a slice level also goes down thereby enabling reading of a signal at a fine level.
