Abstract: A superconducting wire rod according to an aspect of the present disclosure is a superconducting wire rod having a flat cross-sectional shape which is characterized in that a voltage is generated with a lower current density or a higher voltage is generated with the same current density in a region on at least one end side in a wire rod width direction as compared with a region other than the region on the at least one end side.

Abstract: In order to obtain a heating and cooling system capable of localized cooling or heating a given area, a heating and cooling system includes: a supply section configured to supply a heating medium; and a double pipe unit including: an inner pipe, connected to the supply section, through which the heating medium flows, and an outer pipe disposed at an outer peripheral side of the inner pipe, the outer pipe including a space between the inner pipe and the outer pipe, the space being maintained at a vacuum, portions in which a degree of vacuum of the space is different, or in which the degree of vacuum of the space is adjustable.

Abstract: A transportation pipe includes a main-body vacuum insulated pipe, a central pipe, and a connecting vacuum insulated pipe. The main-body vacuum insulated pipe including a double pipe structure includes a vacuum part in a region between an inner pipe and an outer pipe. The central pipe through which a fluid to be transported flows, is arranged in the main-body vacuum insulated pipe. The connecting vacuum insulated pipe having a double pipe structure includes a vacuum part in a region between an inner pipe and an outer pipe. In a state in which two main-body vacuum insulated pipes are inserted into the connecting vacuum insulated pipe from respective ends of the connecting vacuum insulated pipe, ends of the main-body vacuum insulated pipes are away from one another, and the main-body vacuum insulated pipes are connected to one another via the connecting vacuum insulated pipe.

Abstract: In order to obtain a highly versatile superconducting cable capable of absorbing differences in thermal contraction amounts that arise between three members, these being a cable core, an inner tube, and an outer tube, and to obtain a superconducting cable manufacturing method of the same, a superconducting cable includes a thermal insulation vacuum tube and a cable core. The thermal insulation vacuum tube includes an inner tube fixed at both ends and having a cooling medium filled inside, and an outer tube disposed at an outer peripheral side of the inner tube with a space between the outer tube and the inner tube maintained at a vacuum, and is configured to include a winding section wound with one or more turns. The cable core is fixed at both ends and disposed inside the inner tube.
