Title: Vacuum circuit breaker
Inventor: OTOBE KIYOBUMI
IPC: H01H33/66
Filed: 1989-09-28
Abstract: PURPOSE:To prevent heat generation on an electrode part at a closing time by providing a flexible coil electrode having a spring action in the axial direction between a conduction axis and a main electrode. CONSTITUTION:A flexible coil electrode 38 composed of a multilayer thin plate or the like and having a spring action in the axial line direction of a movable conduction axis 18 is provided between the tip peripheral part 18a of the movable conduction axis 18 and the under surface peripheral part 35a of a main electrode 35. At a closing time of a vacuum circuit breaker 30, a movable electrode 32 is brought in contact with a fixed electrode 31, then the movable electrode 32 is pushed opposing to the spring action of the coil electrode 38 for making the tip part of the movable conduction axis 18 in contact with the rear of the main electrode 35. Then, a current of a feeding wire flows from the end of the movable condition axis 18 directly to the main electrode 35 while coming to flow through the arm part 38a and the circular are part 38b of the coil electrode 38 to the main electrode 35 thus to enlarge a passing sectional area of the current. The resistance of this electrode part, therefore, becomes smaller thus to reduce an amount of heat generation.

Moreover, temperatures inside and outside the rooms, which are obtained by the sensors 9a to 9d and an open-air temperature sensor 7 serving for a reference, are inputted 5. While the conditioners 10a to 10d operate, CPU 1 measures a value of (temperature in each room - open-air temperature) Xcapacity of each room in every prescribed time and memories 4 it as calories consumed in each room. The memorized content is displayed 2 and checked up at a necessary time and modified as occasion calls, and the calories consumed by each of the conditioners 10a to 10d and other items are printed by an output device 3.

Abstract: PURPOSE:To reduce the number of steps of winding by forming a superconducting coil and a closed circuit, winding only one of two non-inductive winding of a permanent current switch for turning ON, OFF a permanent current from the folding section of the start of winding, and winding, after one layer winding is completed, the remaining one thereon in the same direction. CONSTITUTION:Only one of a superconducting lead 1a is first wound from the folding section 2 of the start of winding, and a superconducting lead 1b is wound, after one layer winding is completed, on an interlayer insulated winding in the same direction as that of the lead 1a. Thus, the directions of currents flowing to the adjacent leads 1a of a first layer are all the same, but since the directions of the currents flowing to the leads 1b of a second layer are reversed at its folding sections, they become reverse to those of the first layer, and generated magnetic fields cancel each other to obtain a self-magnetic field being '0'. Thus, a non-inductive winding coil having the same as that when two windings are simultaneously wound can be obtained. The number of steps of winding is reduced thereby to obtain an economic permanent current switch.

A silicon oxide film 6 is formed onto the surface of the n<-> layer 3, polycrystalline silicon is deposited on the oxide film 6, and a gate electrode 7 and the gate oxide film 6 are formed through patterning by the same mask. Ions are implanted by utilizing the gate electrode 7 as a mask, and a p<+> layer 4 is shaped through thermal diffusion. An n<+> layer 5 is formed through ion implantation while using the gate electrode 7 and a photo- resist film as masks and thermal diffusion. A source electrode is formed through an insulating film 10 and a drain electrode on a surface on the reverse side, thus completing an element. When the resistivity of the n<-> layer 3 as a third region is increased to high resistivity of 120OMEGA.cm or more at that time, a depletion layer quickly reaches a second region at a turn-OFF time. Accordingly, an insulated gate type bipolar transistor having small turn-OFF loss can be acquired without increasing ON voltage.
