Title: Method and device for forming secondary work material by laser beam welding of thin plate
Inventor: MEIER MARKUS
IPC: B23K26/26
Filed: 1993-04-09
Abstract: PURPOSE: To dispense with precision cutting and accurate positioning by plastically deforming at least one sheet before or inside the weld zone and reducing a gap width between the sheets. CONSTITUTION: A sheet 2, a thicker one of the two sheets 1, 2, is reduced in thickness by two mash rollers 4, 5. As a result, a material flow is caused in the direction of the arrow 7 in the plastically deformed sheet, reducing the width of the gap. In this case, the two mash rollers 4, 5 have a roller zone 8 for rolling over the sheet 2, a roller zone 9 for entering the sheet 2 in order to shift the material in the direction of the gap 3, and a roller zone 10 for rolling over the sheet 2. The roller zone 9 is constituted so that the intrusion depth of the mash roller into the sheet 2 becomes larger as the gap width is increased. Consequently, the mash roller intrudes 0.1 mm, as a result a material shift of about 0.2 mm takes place in the area of the gap 3.

An eccentric part 22 is eccentrically rotated in a housing chamber 14. When the eccentric part 22 is eccentrically rotated, the shape of an enclosed space S is changed from a crescent shape into a ring shape. The capacity of each small chamber S1 to S4 is changed in association with the shape change of the enclosed space S. As a result, fluid in each small chamber S1 to S4 is passed each clearance (g) formed between the end part of vanes 3A, 3B and the inner circumferential surface of the housing chamber 14, and the fluid flows in/out from the other small chamber.  At this time, resistance against circulation of the fluid is generated since the clearance (g) is set large to such a degree that it can act as an orifice.

Title: Subscriber circuit test system
Inventor: SHIBANO SHIYOUGO
IPC: H04M3/30
Filed: 1984-04-27
Abstract: PURPOSE:To attain earlier troubleshooting and repair by adding a prescribed current to a subsriber circuit from a subscriber idle/busy supervisory circuit of a common controller at the trasmission connection of a subsriber in a common control exchange and applying reverse bias to a line C diode in a main link to make the nonconductive. CONSTITUTION:A common controller MKR in the subscriber circuit test controls a main link LINK and conducts the test when a trunk TRK and a subscriber circuit LC are connected. First, a TST relay in the common controller MKR is actuated and its contact tst connects a current source I to a subscriber idle/ busy supervisory lead. The contact tst of the TST relay cuts off temporarily the restoring circuit of the common controller MKR at the same time. When a potential across the coil of the L relay is +48V or over, a -48V potential of the L relay power supply is cancelled and the line C potential is a positive potential. When the line C potential reaches a positive potential, the line C diode DO of the main link LINK is brought into a reverse bias state. Thus, the subscriber circuit LC is separated electrically from the main link LINK to discriminate line contact or line open.
