摘要： A system for resistance welding in which the welding voltage between the electrodes is controlled by changing the pressure applied to the electrodes or the firing phase angle of the welding current in accordance with a reference voltage curve or a reference voltage integration curve. The system comprises a voltage sensor, a reference voltage generator, a differential amplifier, and a pressure control device, or a calculating unit for determining an appropriate firing phase angle of the welding current. The system thus improved can ensure a stable, good welding quality, since the welding voltage is always controlled by a series of optimum welding voltages, during the welding process, in accordance with a reference voltage curve with respect to time, preferably in terms of cycles of the welding current.

摘要： An air-flow control valve of the structure in which a soft foamed sheet (2) is joined to one or both surfaces of a valve body (1) made of a synthetic resin as a unitary structure via a sheet (3) for preventing the oozing of resin. The ooze-preventing sheet (3) is stuck with an adhesive or the like onto one surface of the soft foamed sheet (2) in advance, and a synthetic resin for forming the valve body (1) is placed on the stuck surface of the foamed sheet (2). Or, another foamed sheet (2) with its sticking surface being on the lower side is further placed thereon, followed by stamping. Therefore, the foamed sheet (2) is not peeled off, and the air-flow control valve exhibits sufficient buffer function against the rigid valve body (1).

摘要： A preform (15) is hung from an arm (72) into a heating furnace (74). The heating furnace (74) has five heater units (90-94). A gas supply device (77) supplies nitrogen gas to the heating furnace (74). The heating furnace (74) is divided into five sections by orifices (95-100), and the temperature of each divided section is controlled by the heater units (90-94) provided in each section. A seal member (106) attached to the top side of the heating furnace (74) shields the heating furnace (74) from external air, so it is possible to prevent turbulence in the divided sections in the heating furnace (74).
