Title: Method and device for controlling arc length in non-consumable electrode type automatic welding
Inventor: OGASAWARA TAKAAKI
IPC: B23K9/127
Filed: 1986-07-17
Abstract: PURPOSE:To enable a stabilized arc length control even if the response of a control system is remarkably made higher by monitoring a feeding wire and the body to be welded or the voltage between electrodes in order to control an arc voltage in the set voltage. CONSTITUTION:The voltage Va between a feeding wire 7 and the base metal 5 to be welded is detected by a differential amplifier 20 and fed to a comparator 23 through a filter 21. The comparator 23 sends out an output by comparing with a wire separation discriminating reference signal Vak. A signal generater 24 makes a wire separation detecting signal with the waveform formation of the output of the comparator 23 and feeds to a sample holding circuit 11. The circuit 11 receives the signal A and holds the arc voltage V with its sampling at its rise. Since the arc voltage V to be compared with the set arc voltage by the comparator 13 becomes the voltage reduced sufficiently the stability of the control system can be secured even if the gain of an amplifier circuit 15 be taken higher.

Filed: 1981-10-19
Abstract: PURPOSE:To avoid an erroneous transfer by forming a stable magnetic domein which is not easily varied by a bubble generating magnetic field or a bias magnetic field which are applied when to generate or eliminate bubble to a bubble film or to transfer bubble and so forth.

Title: Detecting device for height of four-wheeled vehicle
Inventor: SEKI GENICHI
IPC: B60G17/015
Filed: 1979-12-24
Abstract: PURPOSE:To obtain the detecting device for the height of the vehicle which is simple in construction and easy to fit by enabling detection of the height of the vehicle in the front and rear parts of the four-wheeled vehicle by using one detecting elememt. CONSTITUTION:When the height of the vehicle is large, a swing arm 6 rotates as shown by a chain line 6' and thereby a beam 16 connected to a shaft 12 is moved as shown by a chain line 16'. In this case, the effective length of the beam 16 in the horizontal direction changes by 2delta. However, the change in the shafts 11 and 12 is absorbed by an elastic body 13 inserted between tubular bodies 14 and 15 and thus no bend is produced in the beam 16, and therefore, the displacement (h) of the beam 16 in the vertical direction is detected correctly by the detecting element 17. Since this displacement is proportional to the change in the height of the vehicle, the nearly fixed height of the vehicle can be retained irrespective of the weight of loading, etc. by controlling the height of the vehicle with the output of the detecting element 12.
