In this method, the superconducting coupling part is interposed with a layer of the same quality as the superconducting ring, and the non-superconducting coupling part is interposed with a layer that is similar to the superconducting ring and cannot be superconducting, making the whole superconducting. They completed a manufacturing method for superconducting coils that involves firing. In the above, an approximate substance is a substance that does not have superconducting properties but has similar thermal properties, for example, in the case of yttrium, barium, and copper, when yttrium or barium is set to 172 or more (including 0). means. Of course, it would be sufficient to reduce yttrium or barium, or both, to the extent that the approximate material loses its superconducting properties.

It was integrally formed by firing with a layer interposed therebetween or a ring formed partially of a superconducting material. In addition, in the non-superelectric coupling part, a powder layer of a material with a different component ratio in the superconducting material (provided that it does not have superconducting properties and the thermal properties are almost the same) is interposed, or this powder is formed by press molding etc. The insulating layer is formed by firing the ring, and the ring partially made of a superconducting material and the ring partially made of a non-superconducting material are the same integral link, and the thickness is 0.5 mm to 0.5 mm. It is thought to be around 1m+n. By re-firing the entire structure as described above, the layer of the same quality as the superconducting ring constitutes a superconducting fiber, and is sintered integrally.

The non-superconducting material has thermal properties during firing etc. that are similar to those of the super conductive material, has a high affinity with the B conductive material, has a strong bond, and exhibits high insulation properties during use. is desirable.

By doing so, since a superconducting coupling part and a non-superconducting coupling part are provided in each contact part, when a large number of superconducting rings are coupled, the whole becomes a series of integrated superconducting coils. That is, since no electrical resistance occurs in the superconducting joint, the entire structure is the same as a coil made of superconducting material.
