Title: Innovations of Tsukimitsu Higuchi
Introduction
Tsukimitsu Higuchi is a notable inventor based in Nagoya, Japan. He has made significant contributions to the field of materials science, particularly in the development of sliding members and copper-based sliding alloys. With a total of 12 patents to his name, Higuchi's work has had a considerable impact on various industries.
Latest Patents
One of Higuchi's latest patents is a sliding member designed to vary friction force without changing contact pressure. This innovative sliding member is constructed by covering a steel plate with sliding materials that differ in friction coefficient. The design allows for a low friction coefficient material to be placed in the middle, with materials that gradually increase in friction coefficient toward both terminal sides. This configuration ensures that the friction force increases as the counterpart member moves in either direction.
Another significant patent is for a copper-based sliding alloy that excels in wear resistance and anti-seizure properties. This alloy contains a lead phase dispersed within the copper matrix, which includes hard particles such as SiC and TiC. The inclusion of these hard particles enhances wear resistance while the soft lead phase acts as a cushion, reducing the impact on mating members and minimizing lead falling-off.
