Title: Optical coupling element interface circuit
Inventor: HASEGAWA YOSHINORI
IPC: G02F1/35
Filed: 1987-05-06
Abstract: PURPOSE:To obtain a stable hysteresis output by the least number of components by feeding the output of a light receiving element which is coupled optically with a light emitting element through a medium to be detected back to the light emitting element positively. CONSTITUTION:Projection light from a light emitting diode 2 is reflected by a reflecting plate 10 which rotates in synchronism with a motor 9 and its reflected light 12 is made incident on a phototransistor 13. The photocurrent 15 of the phototransistor 13 increases or decreases corresponding to the sum of the reflected light 12 from the reflecting plate 10 and disturbing light 15. Further, while the projection light 11 from the light emitting diode 2 impinges on the part of a black area of the reflecting plate 10, the intensity of the reflected light 12 is extremely weak, so a little photocurrent 15 flows and the transistor 4 stays off. Then when the motor 9 rotates and the position where the projection light 11 impinges moves gradually from the black area of the reflecting plate 10 to a white area, the photocurrent 15 increases gradually and a positive feedback loop is formed. Consequently, the stable hysteresis output is obtained by the least number of components.

Title: Apparatus for detecting welding magnetic field
Inventor: TSUKA KENJI
IPC: G01R15/24
Filed: 1989-04-28
Abstract: PURPOSE:To detect a welding current with high accuracy by detecting a change of a space electron current as a change of the intensity of emitted light on the basis of the fluctuation of the magnetic field formed by the space electron current at a welding place. CONSTITUTION:A detection element 1 is arranged in such a state that the opti cal axis thereof becomes parallel to a magnetic field generated by an arc so as to correspond to the discharge gap 11 between a base material 9 and an electrode 10 constituted of a core or wire at the welding place of an arc welding apparatus and the plane of polarization of the light passing through the element 1 is rotated by the magnetic field excited by a generated arc. Therefore, since the magnetic field generated by the current change in the arc fluctuates, the angle of rotation of the plane of polarization of the light passing through the element 1 is changed by the fluctuation of the magnetic field and the voltage value outputted from a light detection means 3 changes corresponding to the current value in the arc and a welding current can be detected by detecting a welding magnetic field.

Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To provide an optical reception use IC that an amplifier section operated analogically and a digital drive section operated digitally are configured in a way of one-chip mode. SOLUTION: A delay circuit 110 that positively delays a signal transmitted through a path from an amplifier section 102 to an external drive section 104 is arranged onto the path so that a timing when a mid-position of each 1-bit period of a base band digital signal is given to the amplifier section 102 is deviated from a timing for a switching operation of the external drive section 104. Thus, even when the amplifier section 102 and the digital drive section 103 are configured in a way of cone-chip mode, occurrence of a noise due to switching of the external drive section 104 in the mid-position of the 1-bit period of the base band digital signal is avoided.
