摘要： To provide a thermal insulation piping with no radially projecting part from a periphery thereof, so as to facilitate insertion of the thermal insulation piping into a pipeline or equivalent. In a thermal insulation tube 10 having a vacuum layer between an inner tube 11 and an outer tube 12 , an evacuation port 30 for vacuum evacuation is oriented parallel with a longitudinal direction of the thermal insulation piping at an end of the thermal insulation tube 10 . This construction can produce the thermal insulation tube 10 with no radially projecting part from a periphery thereof, thus providing improved workability when the thermal insulation piping is contained in the pipeline or equivalent. Further, a flexible pipe(s) 40 is/are preferably connected to the evacuation port(s) 30 . This can allow increased positional tolerances in the connection of the evacuation port(s) to a vacuum evacuation device.

摘要： A first flange (11) and a second flange (12a) are superposed and fastened with a bolt (B) and a nut (N) in a fastening operation, to implement a fastening structure used at temperature lower than atmospheric temperature for the fastening operation. Assuming that the first flange (11) has a thickness L1 and a coefficient of linear expansion alpha 1, the second flange (12a) has a thickness L2 and a coefficient of linear expansion alpha 2, superposed first flange (11) and second flange (12a) have a thickness L, and the bolt (B) has a coefficient of linear expansion alpha , a relation of L. alpha ≥ L1. alpha 1 + L2. alpha 2 is satisfied, i.e. heat shrinkage of the bolt (B) is not smaller than the total heat shrinkage of the first and second flanges (11, 12a). Thus, impairment of sealing property due to heat shrinkage is avoided at a flange junction used at low temperature.

摘要： A phase split structure of a superconducting cable includes three cable cor es each having a shield layer provided around a superconductor, a splitter box housing the three cable cores extending from an assembly portion where the three cable cores are assembled into the cable, in a state in which the cable cores are spaced apa rt from each other, and a shield connecting portion connecting respective shield layers o f the cable cores to each other within the splitter box. The shield connecting portion allows the cable cores to have their respective shield layers connected together with l ow resistance and each shield layer can pass a current substantially equal in magnitude to that which each superconductor passes. Thus in each shield layer a magnetic field can b e formed having a level that can cancel a magnetic field generated from each superconductor. The structure can thus effectively prevent a large magnetic field external t o the cable core.
