Isao Sugihara is a notable inventor based in Hitachi, Japan. He has made significant contributions to the field of heating technology, holding 2 patents that showcase his innovative approach to heating systems.

Latest Patents

Sugihara's latest patents include a "Method of heating piping arrangement and heating coil." This invention relates to a method of heating a piping arrangement and a heating coil used in the heating process by heating pipes through high-frequency wave induction. The spacing between the pipe's outer surface and the heating coil is varied in compliance with changes in the configuration of the heating coil. According to this invention, even if the coil configuration is particularly changed, it is possible to heat the pipes uniformly to obtain a uniform temperature distribution. Another significant patent is the "Heat-treating method of weld portion of piping system and heating coil." This method involves heat-treating a weld zone of a piping system, where the outer wall of a pipe is heated by means of a heating coil while a coolant is present in the pipe. This establishes a temperature difference between the inner and outer walls of the pipe, thereby preventing the weld zone from corroding and cracking due to stress.
