摘要： PURPOSE:To lessen electric resistance of a connecting part and form the stabilized connecting part without attenuation of a magnetic field by connecting respective end parts of both compound type superconducting wires to each other with cold-welding or welding in the state leaving the initial superconducting core wires of which respective end parts to be connected are not heat-treated as it is. CONSTITUTION:When compound type superconducting wires are connected to each other, materials other than Nb12 as the superconducting core wire in respective ends of both wires not heat-treated are removed by etching, a mechanical means and the like. The superconducting core wires 12a, 12b not heat-treated at each end of the superconducting wires 16a, 16b to be connected are then superposed, put into a sleeve 18, and the sleeve part is spot-welded in the direction of the arrow P. Consequently, since these superconducting core wires 12a, 12b are kept as it is of Nb, the superconductive connection can be facilitated.

摘要： PURPOSE:To provide an inexpensive and mechanically strong superconducting coil by disposing a spacer for a cooling channel among winding layers and performing winding, and thereafter performing a high temperature heat treatment for production of a superconducting material, and further impregnating a resulting winding with epoxy resin. CONSTITUTION:A compound superconducting wire 2 is wound to yield a superconducting coil 1 by a wind-and-react method. A spacer 11 for a cooling channel to construct the coiling channel is arranged among winding layers of the superconducting coil 1. A spacer 11 structure is constructed with an insulating material 12 formed by knitting into a bag shape heat resistant fibers, e.g. ceramics aluminum fibers and with a metal piece 13 comprising stainless steel for example inserted into the interior of the insulating material 12 for resisting a high temperature heat treatment and reinforcing the spacer. The spacer 11 is disposed among the winding layers and winding is performed, and thereafter the high temperature heat treatment is performed to produce a superconducting material. Thereafter, the resulting coil is impregnated with epoxy resin 14. Hereby, the inexpensive and mechanically strong superconducting coil 1 is yielded.

摘要： PURPOSE:To increase the quantity of the refrigerant at the section in high need of accelerating cooling further according to the condition of a rotator such as temperature distribution, cooling speed, etc., by providing a solenoid valve or a relief valve in a discharge path, and providing a device for supplying driving power to this solenoid valve or the relief valve from a static part. CONSTITUTION:A discharge pipe 21, which leads to air, is provided at the end on the driver side of a refrigerant tank 4. The discharge pipe 21 is provided, inside the center hole 16 of the rotary shaft outside a vacuum heat insulating layer 6, with a spring-type relief valve 22 which is equipped with a operating function of becoming full open by overcoming spring force by electromagnetic force at current application. Moreover, gas-like refrigerant passages 23a, 23b, and 23c, which leads to the space between the generator outside a rotor from each outlet of each torque tube 8a and 8b at the end 14 on driver side and the end 9 on the side opposite to the driver and the gas-like refrigerant passage of a radiation shield 7, are provided, respectively, piercing a cold rotor 5. A solenoid valve, which opens fully at current application and closes fully at current nonapplication, is provided at the outlet of each gaseous refrigerant path.
