摘要： A rod 1 made of superconducting oxide is soaked in a molten normal conductor 2 to join the rod 1 and the normal conductor 2, whereby a superconducting oxide current lead is prepared. As a result, a contact resistance at the interface between the superconducting oxide and the normal conductor can be reduced. Consequently, Joule's heat at a current lead having a small cross sectional area can be suppressed low, which in turn realizes the reduction of the load on a freezer and the amount of evaporated cooling solvent, with respect to a superconducting coil.

摘要： An illuminated pushbutton switch cover member has a key seat and a resin key top. An indicator portion provided in the resin key top is illuminated with light from an internal light source provided below the key seat, and the light is emitted from the inside to the outside of the cover member through the indicator portion. The cover member is constructed by joining the resin key top to the key seat. The key seat is formed of a thermoplastic elastomer that prevents leakage of light, and an opening for passage of light is formed in the key seat to expose the bottom side of the resin key top to the internal light source. Thus, light from the internal light source can reach the bottom side of the resin key top directly without being attenuated. The indicator portion of the resin key top can therefore be illuminated with high luminance.
