PURPOSE: To increase the current capacity of a superconductive switch by bending a superconductive wire at a center part and starting a coil winding from the position of a bending part to a core body and then performing winding with one side for the bending part as an input part and the other as an output part side by side. CONSTITUTION: The central part of a superconductive wire 2 is bent in a loop and is arranged in a recess 31 being provided at the terminal of a core body 12. Input parts of wires 1 and 2 are adjacent each other, and the output parts of the wires are also adjacent each other. The wires 1 and 2 are withdrawn from a switch at the terminal of the core body 12 and that at an opposite side with the recesses 30 and 31. The terminal parts 1i and 2i form a superconductive lead wire for connection to a superconductive circuit. Also, terminal parts 10 and 20 constitute a superconductive lead wire, thus increasing the current capacity of a superconductive switch within a magnetic field. COPYRIGHT: (C)1989,JPO
56	Superconductive electromagnet device	JP9238483	1983-05-27	JPS59218710A	1984-12-10	MITSUNE SUSUMU
PURPOSE:To contrive prevention of burning of an electromagnet by a method wherein a bidirectional constant voltage element such as a varistor and the like is used as a discharge element, thereby enabling to prevent generation of a branching-off to the discharge element even when said element is being excited or demagnetized. CONSTITUTION:A bidirectional constant voltage element 8 such as a varistor and the like is used as a discharge element instead of a resistor 1 and a diode 2. The operating voltage of said constant voltage element 8 is selected in such a manner that it will be a little higher than the exciting or demagnetizing voltage of the electromagnet. As a result, no branching-off is generated on the discharge element 8 when it is excited or demagnetized, and no heat is generated. When an OFF position is given to a superconductive switch 4 and the electromagnet is quenched, a voltage is generated at both ends of the electromagnet, the discharge element is turned to a constant-voltage resistor, and the magnetic energy of the electromagnet is absorbed by said constant-voltage resistor. An electric discharge is generated in the state of constant voltage, the current on the electromagnet is reduced rectilinearly as time elapses.

PURPOSE:To realize a change into high resistance on a turn-OFF and a stabilization to a high degree on a turn-ON easily and simultaneously by using a superconducting type switch and a mechanical switch in parallel and interlocking the switches and making the most of each characteristic and constituting a permanent current switch. CONSTITUTION:The superconducting type switch 51 and the mechanical switch 52 are connected in parallel, and their switching operation is synchronized and interlocked, thus constituting the permanent current switch. Consequently, a parallel circuit consisting of three of the superconducting type switch 51, the mechanical switch 52 and a superconducting coil 2 is connected to an excitation power supply 3, and the permanent current switch consisting of the superconducting type switch 51 and the mechanical switch 52 and the superconducting coil 2 are encased in a cryostat 4. Currents flowing through the superconducting type switch 51 are taken over by the mechanical switch 52 and the sudden attenuation of currents is inhibited when the superconducting type switch 51 generates a quenching, and the switch 51 returns again when unstable primary factors are eliminated.
