CONSTITUTION:A control unit 15 for controlling an AC power source 10 for applying discharge voltage is provided between AC power sources 14 for triggers and electrodes 1. When discharge is started, the voltages from the AC power sources 14 for the triggers are applied to trigger pins 3 through capacitors 4 based on the command of the control unit 15. Thus linear discharge is generated. Discharge is generated in discharge region 2, in which the electrodes 1 face to each other, owing to the charged particles yielded by said linear discharge. Laser gas 9 is excited and laser oscillation is started. Light is reflected between a partial reflecting mirror 11 and a total reflecting mirror 12. Part of the light is outputted through the partial reflecting mirror 11 as laser light 13. When the main discharge is started between the electrodes 1, the control is performed so that the power supply to the trigger pins 3 from the AC power sources 14 for the trigger pins 3 is stopped. Then the excessive power supply can be prevented.

Title: Vent type extrusion molding machine
Inventor: MATSUMOTO KEIJI
IPC: B29C48/76
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To clean a solid matter stuck to a vent using a simple means by providing a freely attachable and detachable bushing covering the inner wall of a vent. SOLUTION: The vent type extrusion molding machine is, for example, equipped with a cylinder, a screw 2 introduced through the interior of the former, a hopper 3 installed in the upstream of the cylinder 1 and a die 4 provided at the tip of the downstream of the cylinder 1. Further, a vent part 5 is set in the middle part of the cylinder 1 and has a vent 6 formed communicating with the intrapipe part of the cylinder 1. In this vent 6, a freely attachable and detachable bushing 7 covering the inner wall of the vent 6 is insetted. Therefore, when a molten material sticks appreciably to the inner face of the bushing 7, resulting in the narrowing of the vent 6, the bushing 7 is removed from the vent 6 and a spare bushing 7 is immediately introduced inside. Thus the molten material does not stick to the inner face of the vent 6 directly.  As described, the cleaning of the vent 6 is completed only by replacing the bushing 7 with a spare bushing, so that the cleaning operation can be made extremely simple.

Filed: 1984-06-06
Abstract: PURPOSE:To improve the yield of a steel ingot in continuous pouring in a casting mold from an immersion nozzle by decreasing the ingot drawing speed while some molten metal remains in a tundish in the end period of said pouring to provide a riser effect thereby preventing the generation of a pipe in the ingot. CONSTITUTION:The drawing speed for the ingot 1 is decreased in the period when some molten metal 2a remains still in the tundish in the end period of continuous pouring from the immersion nozzle into the casting mold 5. The substantial riser effect is obtd. in the unsolidified parts 6a, 6b in the mold 5, by which the generation of the pipe is prevented. The nozzle 4 is cut away in the top surface part of the mold 5 when the molten metal solidifies to the molten metal surface in the casting mold. The remaining nozzle part of the ingot may be cut away in the subsequent stage. The yield of the ingot is improved. The cost of the ingot 1 is further reduced if an inexpensive throw-away nozzle is used for nozzle 4.
