Patent JP-S58210607-A (JP)
Title: Electromagnetic device
Inventor: TANAKA TAKANOBU
IPC: H01F7/16
Filed: 1982-05-31
Abstract: PURPOSE:To easily permit adjustment of the sensitivity current even in an assembled state and to allow electromagnetic devices with different sensitivity currents to be composed of the same parts by a construction wherein the resilient force of a spring acts on a movable yoke such that the free end of the movable yoke is made to depart from one of upper and lower yokes. CONSTITUTION:When current passes through a coil 13, this current produces the magnetic flux through a path comprising an upper yoke 2, side yoke 4, lower syoke 3, fixed core 10, space including return spring 11 and a movable core 6, and a path comprising a depending piece 15 of the upper yoke 2, gap l, movable yoke 14, lower yoke 3, fixed core 10, space including return spring 11 and the movable core. The magnetic flux thus produced attracts the movable core 6 toward the fixed core 10. Prior to such attraction, the movable yoke 14 is attracted against the turning force of a spring 16 to come into contact with the depending piece 15 of the upper yoke 2. Then, when the force attracting the movable core 6 overcomes the resilient force of the return spring 11, the movable core 6 is moved downwards. Thus, since the movable core 6 is actually attracted following movement of the movable yoke 14, the movable core 6 is moved downwards with a strong attracting force.

Title: Laser working device
Inventor: INOUE KIYOSHI
IPC: B23K26/046
Filed: 1983-06-01
Abstract: PURPOSE:To provide a titled device which controls automatically the focusing position of laser light from a focusing lens system and improves working accuracy by constituting the device in such a way that the control for moving the laser light in the optical axis direction is accomplished automatically by a specific control device. CONSTITUTION:A motor 8 is first run and a casing 7 is once approached slightly to the direction of a work 22 in order to match the focusing point of laser light with the working surface of the work. If the focusing point of the light for collimating exists, for example, on the inside of the work 22, the light spot generated on the working surface spreads further and therefore the light spot on the focal plane of the 2nd collimating lens 18 spreads further, thus resulting in the slightly decreased intensity of the light detected by a photodetector. The motor 8 is run in such a case to part the casing 7 by a slight distance from the work direction so that said light is detected only by the photodetector. A control device 21 emits the command to irradiate the laser light to the work 22 when the focusing point of the laser light matches with the working surface of the work 22. As a result the control for moving the laser light in the optical axis direction thereof is automatically accomplished and the focusing position thereof is automatically controlled, by which manpower is lessened and the working accuracy is considerably improved.
