When bending a superconducting cable of a stack conductor structure in which a plurality of layers of tape wires are stacked, a twisting process is performed for the superconducting cable immediately before a bending portion of the superconducting cable.

Superconducting cable and installation method of the same

When temperature raising is performed, temperature of a superconducting cable is uniformly raised over an entirety of the superconducting cable. The superconducting cable assumes a linear shape when cooled, and deforms into a helical shape when temperature raising is performed. In a former having a twisted wire structure, twisting directions of an outermost layer and a layer next to the outer most layer are set to be the same, enabling stabilization of the helical deformation of the superconducting cable including the former when the temperature raising is performed.

A superconducting power transmission system that comprises an inner pipe housing a superconducting cable therein, a radiation covering at least a part of the inner pipe from outside; and an outer pipe housing the inner pipe and the radiation shield therein. A vacuum is created in a space from an inside of the outer pipe to an outside of the inner pipe with the radiation shield therebetween. The system further comprises at least one radiation shield pipe, housed in the outer pipe and thermally coupled with the radiation shield, a liquefied natural gas (LNG) as a second cryogen for the radiation shield being made to flow through the radiation shield pipe.

In a thermally insulated double pipe, a structure is provided in which an inner pipe may be prevented from being appreciably offset relative to an outer pipe due to thermal contraction. The structure includes an inner pipe, within which a superconducting cable is mounted, an outer pipewithin which the inner pipe is housed, with the inner and outer pipes constituting a thermally insulated double pipe, and an inner pipe support membersupporting the inner pipe. The inner pipe support memberis secured to the inner and outer pipes.

Superconducting power transmission system

A method of manufacturing a superconducting tape wire, wherein a reduction in critical current in the superconducting tape wire and the effective AC loss are suppressed. To manufacture the superconducting tape wire, the filaments filled with superconducting material powder and having a flat elliptic or rectangular cross section are disposed in a pipe having a shape whose sides in a pressing direction have a smaller length than adjacent sides, and then the pipe is compressed in the short-side direction to form the pipe in a tape shape.

A power transmission cable with easy laying, reduced heat invasion and enhanced efficiency. The cable comprises an inner pipeencasing a refrigerant passage, a superconducting memberand an electrically insulating portion; an outer pipe; a vacuum adiabatic insulating sectionbetween the inner and outer pipes; an inner pipe support ring disposed between the inner and outer pipes so that it is slidable along the outer side of the inner pipe; an outer pipe support ring fixed to the inner side of the outer pipe; and a support member which is disposed between the inner and outer pipe support rings.

Direct current superconducting power transmission cable and system

A superconducting cable having improved transmission efficiency facilitates the laying operation and reduces heat intrusion. The superconducting cable comprises a first pipewithin which are accommodated a refrigerant passage section, a superconducting memberand an electrical insulating section, and a second pipearranged on the outer side of the first pipe. A vacuum heat insulating sectionis provided between the first and second pipes. The second pipe is formed of a ferromagnetic material.

Cutting method of ingot into wafers along cleavage plane. Onto surface of single crystal ingotis implanted ion beamto generate lattice defects in a direction defined by the crystal axes that corresponds to the cleavage plane. Cleavage is generated by applying a shock by a knife edge to the position of the lattice having a cutting face as a cleavage plane. Production time of waters is reduced with a more numbers of sliced wafers from one ingot.

In a superconducting coil system an m&times;n array of wound cores are arranged and n pairs of strands, totalling at 2n strands, are passed in pairs through the hollow center of the cores so that the current will flow in mutually opposite directions in each paired strands. The system can reduce AC loss, completely avoiding current imbalance in strands and being designed easily.
