Patent number: 9531157Abstract: A lighting circuit is configured to turn on or off a semiconductor light source in accordance with a turning-on/off instruction signal. The lighting circuit includes a pulse input determining circuit and a drive circuit. The pulse input determining circuit receives the turning-on/off instruction signal which is in pulse form in commanding turning-on and which is at a constant level in commanding turning-off. The pulse input determining circuit determines whether or not the turning-on/off instruction signal is in a turn-on state in which the turning-on/off instruction signal is in pulse form. The pulse input determining circuit generates a determination signal which is asserted if the turning-on/off instruction signal is in pulse form. The drive circuit supplies the semiconductor light source with a drive current if the determination signal is asserted. The drive circuit does not supply the semiconductor light source with the drive current if the determination signal is negated.Type: GrantFiled: November 24, 2015Date of Patent: December 27, 2016Assignee: KOITO MANUFACTURING CO., LTD.Inventors: Tomoyuki Ichikawa, Toshihiko Kurebayashi

Patent number: 6650425Abstract: A position measuring laser apparatus includes first and second laser transmitter-receivers and a position measure. The laser transmitter-receiver includes a laser beam emitter for emitting a laser beam, and a laser beam receiver for receiving a laser beam resulting from the emitted laser beam reflected from a reference reflecting mirror. An optical axis of the laser transmitter-receiver is oriented at a required angle toward a moving body. The position of the moving body with respect to the reference reflecting mirror is measured based on a beam receiving signal of the laser beam obtained by the laser transmitter-receiver. The position measure compares a drive signal for driving the laser beam emitter with a beam receiving signal generated by the laser beam receiver to measure the position of the moving body based on the beam receiving signal when the drive signal and the beam receiving signal coincide with each other.Type: GrantFiled: March 22, 2001Date of Patent: November 18, 2003Assignee: Koito Manufacturing Co., Ltd.Inventors: Yasushi Kubota, Makoto Nawa, Toshihiko Kurebayashi
