Abstract: PURPOSE:To reduce an equipment cost and to produce the high-quality electric welded pipe which is free from cold defects by providing an output regulating means which regulates the impedance of preheating coils or welding coils and connecting both the coils to one high frequency power source. CONSTITUTION:A 1st coil 31 and the 2nd coil 32 preheat an open pipe 1 and the welding coil 5 heats the pipe up to the welding temp. Squeeze rolls 2 butt- weld the edge parts to form the pipe 10. The 1st coil 32 constitutes a circle as a whole of a coil half body 31a of about 3/4 circumference and a coil half body 31b of about 1/4 circumference. One end of the coil is connected to a high-frequency power source 4 and the other end to a connecting conductor 33. The 2nd coil 32 constitutes a circle of one circumference. High-frequency current flows like a broken arrow and does not flow to a joint point.

Title: Air venting device of molding die
Inventor: MAMIYA HIROKUNI
IPC: B29C45/34
Filed: 1983-12-14
Abstract: PURPOSE:To completely discharge air and gas from a molding die and moreover prevent an air venting gap from being clogged by molding material by a method wherein an automatic valve is energized downwards by spring force, which is weaker than the force developed by the pressure of the resin applied onto the pressure receiving surface of the valve but stronger than the force developed by the pressure of the air applied onto the pressure receiving surface of the valve. CONSTITUTION:The force of a spring 9 is set to have a strength, which is so stronger than the pressure of the air applied onto a pressure receiving surface 4 that an automatic valve 3 can open an air vent passage 2 against said air pressure and is so weaker than the pressure of the resin applied onto the pressure receiving surface 4 that the pressure of resin closes the automatic valve 3. When resin reaches the inlet part 2a of the air vent passage 2 after the air and gas are discharged, the resin starts to enter a gap formed between the outer periphery of the automatic valve 3 and the inner periphery of the air vent passage 2 and at the same time the pressure of resin is applied onto the pressure receiving surface 4. At this time, the automatic valve 3 is closed by being pushed upwards by the resin before the resin reaches the gap formed between a shoulder part 7 and a valve seat 8, because of the inflowing resistance is large. Consequently, the air vent passage can be sufficiently wide so that the air and gas in the resin inflowing part is surely discharged. In addition, no leakage of material and outflowing of flash through the air vent passage occur because the automatic valve is automatically closed by the pressure of resin.
