Latest Patents

Yamagishi's latest patents include innovative technologies that enhance the performance of superconductors and improve chemical plating processes. One of his patents focuses on a novel composite superconductor that integrates a superconducting material with a normal conducting material. This composite superconductor features closely spaced grooves on its surface, which are in contact with a refrigerant. The design includes ridges that are spaced apart from each other by the grooves and have acutely tapered ends. The surfaces of these grooves and ridges are coated with a thin film of metal or its compound, which has higher heat resistance than the composite superconductor itself. This innovation allows for a high critical heat flux in film boiling and enhances cooling capabilities, ultimately leading to a reduction in the sectional area of the normal conducting material, an increase in effective current density, and miniaturization of magnet size.

Another patent by Yamagishi pertains to an apparatus for applying chemical plating to the inner surfaces of tubular members. This apparatus consists of a tank for storing a plating solution, a table for supporting multiple tubular members for simultaneous plating, and a plating solution distributing member connected to the storage tank via a supply line. The design ensures a liquid-tight seal and allows for efficient plating while maintaining the temperature of the plating solution.
