Title: Ac arc welding power source
Inventor: TERAYAMA KIKUO
IPC: B23K9/073
Filed: 1990-07-06
Abstract: PURPOSE:To eliminate the need for a complicated circuit and a highly precise circuit for a switching element driving circuit by using a self-extinction of arc type unidirectional switching element as switching elements and carrying out ON-OFF control alternatively on the switching elements to supply the induced voltage of a reactor effectively to welding load. CONSTITUTION:An output electric current is detected by a detector 13 and compared with a set signal (er) by a comparator 14 and a differential signal  (e)=(er)-(ef) is supplied to the switching element driving circuit 16. The switching element driving circuit 16 acts as a constant current control circuit to determine phase of output signals S1 and S2 in the direction where this differential signal  (e) decreases. Here, the switching element driving circuit 16 will do if it carries out ON-OFF control on the switching element 10a or 10b without interruption respectively so that an 'on' period overlaps substantially and for this purpose, when the switching elements having the ordinary interruption lag time, for instance are used, it can be realized by making the driving signals S1 and S2 into signals to reverse at the same time mutually.

Filed: 1996-07-10
Abstract: PROBLEM TO BE SOLVED: To smoothly discharge a filter cake from the lower opening of a filter medium and to prevent the clogging of the medium by supporting plural vertical cylindrical filter mediums each contg. a liq. fall resistor freely rotatably with a rotor having a vertical rotating shaft, introducing a liq. to be filtered into the upper opening of the filter medium and filtering the liq. SOLUTION: A rotor 12 is rotated on its rotating shaft 47 to revolve a filter medium 13 around the rotating shaft 47 by a motor 27, and the filter medium 13 is rotated since a planetary gear 65 is meshed with a sun gear 26. Under such conditions a raw liq. is supplied on the upper part of a partition wall 43 in the rotor 12 through a pipe 52 and distributed to the upper opening of the medium 13, hence the raw liq. is filtered by the medium 13, and the filtrate is discharged through a communicating hole 46, trough 23 and discharge pipe 24. The raw liq. not filtered by the medium 13 flows down in the medium 13 with the direction changed by the resistor 14, and hence the filter cake in the raw liq. is meandered or spiraled and dropped and finally discharged from the lower opening.

Filed: 1995-06-26
Abstract: PURPOSE: To easily integrally work a welding end part and easily ensure the strength of the part by forming a door beam by an open pipe which has a slit of a specified width extending over the whole length thereof and contains specified percent carbon by weight, and integrally forming bracket parts formed by spreading the slit into a flat surface at both ends of the open pipe. CONSTITUTION: An open pipe is formed by steep material containing 0.2-0.25wt.% carbon, and at that time, a slit width S is set to 1.0mm or more and high- strengthen working is conducted for the middle part 5 by high-frequency quenching. Though before and after heat treatment, the slit width S is changed linearly, if the slit width S before heat treatment is set to 1.0mm or more, there is no possibility that the edges of the slit come into contact with each other. The change of the slit width S caused by high-frequency quenching is little influenced by a difference in diameter and thickness. Subsequently, the open pipe is flared from the slit 2 to form flat bracket parts 3, 4 by flat forging. The bracket parts 3, 4 are welded on the door.
