摘要： A large-capacity vacuum circuit breaker that can increase a current shutdown capacity and enables its rated current to be increased includes at least two vacuum circuit breaker units placed side by side and connected in parallel. The two vacuum circuit breaker units are operated by a single common operating unit to concurrently perform current shutdown operations.

摘要： A heater has a smooth heating surface and a recess formed on a second surface opposite to the heating surface. The recess is formed between opposite side walls in a lengthwise direction of the heater. Formation of the recess improves the electrical resistance of the heater and the opposite side walls reinforce the heater and prevent deformation of the heater when it is subjected to high temperatures in a semiconductor wafer processing device. The heater has substantially the same width along its lengthwise direction. This improves the control of heat pattern design, because the terminal end portions do not have an expanded shape.

摘要： An electrode of a vacuum circuit breaker has a cup member and a contact. The cup member has an opening and a periphery which is formed with a slit so as to form a coil section. An electric current flows in the coil section so as to generate a longitudinal magnetic field in a direction along an axis of the cup member. The slit is bent and continuously extends on the periphery from a first end of the cup member to a second end of the cup member opposite to the first end of the cup member. The contact is shaped into a plate, and seals the opening of the cup member.
