<P>PROBLEM TO BE SOLVED: To solve such a problem that the conventional method for reinforcing a ring made of a metal such as stainless steel, by fitting the ring over a superconducting bulk body requires very high degree of dimensional accuracy, so that it cannot be employed readily. <P>SOLUTION: In a bulk superconductor including a short cylindrical superconducting bulk body and a surrounding belt of a shape memory alloy which surrounds and pressurizes the circumferential surface of the superconducting bulk body, the surrounding belt pressurizes the superconducting bulk body by recovering the shape, after surrounding the superconducting bulk body. <P>COPYRIGHT: (C)2011,JPO&INPIT |
