摘要： Tape-shaped superconducting wires are made by forming a superconducting film on the substrate. At least the superconducting film is slit, electrically separated into a plurality of superconducting film parts each having a rectangular cross section and arranged in parallel to form parallel conductors. This provides superconducting wires capable of containing AC loss. A superconducting coil is made by winding the superconducting wires described above, wherein the provision of a coil structure containing at least partially a part wherein the perpendicular interlinkage magnetic flux acting among various conductor elements of the parallel conductors by the distribution of the magnetic field generated by the superconducting coils cancel mutually enables a simple structure without transposition to cancel mutually the interlinkage magnetic flux by the perpendicular magnetic field against wires, to contain circulating current within the wires by the perpendicular magnetic field and to make shunt current uniform. This provides a low-loss superconducting coil.

摘要： Methods for implementing production of an oxide superconductor joined member, excellent in electric current transmission performance, without a need of going through particularly complex steps, are provided. When joining together oxide superconductors by use of a solder composed of an oxide superconducting material, a finally solidified portion of the solder is positioned in a region where a transmission path of electric current flowing between oxide superconductor base materials as joined together is not obstructed by, for example, disposing the solder on a face of the oxide superconductor base materials, other than butting surfaces of the oxide superconductor base materials, so as to straddle both the base materials like bridge-building. Current flow is also not obstructed by, for example, shaping junction faces of the oxide superconductor base materials such that at least portions of the butting surfaces thereof are in the shape of sloped open faces, parting from each other. Further, an oxide superconductor joined member is made by joining the base materials with each other through the intermediary of an oxide superconductor, serving as a binder, disposed on at least a face of the base materials, other than butting surfaces thereof.

摘要： The present invention relates to methods for pulling a single crystal wherein the induction of dislocation can be inhibited and a single crystal can be held safely. An apparatus for pulling a single crystal having a straightening vane in the shape of an inverted truncated cone whose upper and lower planes are removed, which is located between a crucible and a single crystal, is used. The gap between the lower end portion of the straightening vane and the surface of a melt filled into the crucible can be selected in the range of 30-200 mm. Where the gap is set large in the range of 30-200 mm, the temperature of the front portion of a seed crystal is raised till the difference in temperature between the front portion thereof and the melt (the range of 1380-1480° C.) becomes almost zero. The seed crystal is brought into contact with the melt, a neck is formed with being heated, and a main body is pulled from the melt. Alternatively, an apparatus for pulling a single crystal having a crucible with through holes formed on the upper part thereof, or an apparatus for pulling a single crystal having an auxiliary heating means which has a body surrounding a seed crystal located near above the melt surface and a transfer mechanism for pulling the body is used in order to achieve the object.

摘要： When a pulled single crystal becomes heavier, the strength of a seed crystal holder made of a carbon material is not sufficient, leading to falling of the single crystal. On the other hand, a seed crystal holder made of metal causes heavy metal contamination, or the strength thereof deteriorates early because of thermal fatigue. Accordingly, a seed crystal holder, comprising an inner cylindrical body made of metal which directly holds a seed crystal, and a carbon cylindrical body arranged around the inner cylindrical body which covers the periphery thereof, is used.
