摘要： A magnetic refrigerator comprising a magnet generating a high-intensity magnetic field, a tube-shaped superconducting magnetic shield, a magnetic working material and a reciprocating means for reciprocatively moving the superconducting magnetic shield or the magnetic working material, the magnetic refrigerator being arranged such that a magnetization process wherein the magnetic working material is magnetized in the high-intensity magnetic field and a demagnetization process wherein the magnetic working material is demagnetized by being accommodated in the hollow section of the magnetic shield are repeated by the reciprocating means so that the magnetic working material generates coldness.By using the property of a tube-shaped superconductor which can shield the magnetism of an external magnetic field passing through the hollow section of the tube and can generate a zero-intensity magnetic field in the hollow section, the magnetic working material magnetized in the high-intensity magnetic field generated by the magnet is inserted into the hollow section of the tube-shaped superconducting shield and is demagnetized in an adiabatic condition to generate coldness. This coldness is used to cool the target cold bath.

摘要： A gas-insulated bushing including an insulating tube filled with an insulating gas, a central conductor centrally arranged within the insulating tube, and a capacitor unit connected to the central conductor and partitioning the interior of the insulating tube. The central conductor has an intermediate constriction to which the capacitor unit is connected and is formed of two connected conductor parts, at least one of which is terminally restricted to form the constriction. A pair of flanges is secured to the ends of respective of the conductor parts and connects the conductor parts at the constriction. A shield member is supported on one of the flanges and spaced apart from the conductor parts at the constriction in order to relieve the electric field at the constriction.
