Title: Straightening machine for pipe material
Inventor: SASAKI TAKESHI
IPC: B21D3/04
Filed: 1981-05-09
Abstract: PURPOSE:To straighten a pipe material without causing a dent etc., by mounting plural hollow die-rolls and a pair of drum-shaped crushing rolls freely rotatably on a rotary frame-body and slanting the latter within a plane parallel to the advancing direction of the pipe material. CONSTITUTION:A pipe material is inserted into a rotating rotary frame-body 20 through guide rolls 2. The inserted material is brought into linear contact with the internal surface of a hollow hole of a die-roll 43 and is given bending moment to straighten uniformly by the actions of revolution and rotation of dies 40. Then the material reaches a final crushing part 50 to be given crushing and bending forces, and is staightened more forcibly. In this case, a pair of drum- shaped crushing rolls 56 is arranged to slant the axial lines of them, and arranged to be in the plane parallel to the advancing direction of the pipe material. Accordingly, the highly accurate straightening is performed because the material is straightened by putting it between the rolls 56.

Abstract: PURPOSE:To enable to start discharge instantaneously even when left to stand in a darkness for a long time by a method wherein an auxiliary electrode is provided on the cathode valve side of a laser tube, so as to discharge between the auxiliary electrode and a cathode. CONSTITUTION:The positive pole of a laser power source 1 is connected to the anode 3 of the laser tube 2, the negative pole to the cathode 4 thereof, the positive pole of an auxiliary power source 7 to the auxiliary electrode 10, and the negative pole to the cathode 4 of the laser tube 2. When the power source 1 is turned on in a darkness by this constitution, a trigger voltage is impressed onto the anode 3, and simuletaneously the trigger voltage of the power source 7 is impressed onto the electrode 10. But, because of being in the darkness, the main discharge between the anode 3 and the cathode 4 does not instantaneously start. However, the electrode 10 projects out directly to a cathode space 12, therefore rare gas is ionized instantaneously, then the glow discharge light between the electrode 10 and the cathode 4 strikes the surface of the cathode 4, and accordingly emits electrons from the surface of the cathode 4. This electron emission enables to start discharge of the laser tube 2.
