Title: Fumio Ono: Innovator in Wire Conductors and Hot Rolling Methods
Introduction
Fumio Ono is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of materials engineering, particularly in the development of wire conductors and methods for hot rolling copper. With a total of 3 patents to his name, Ono's work has had a lasting impact on the industry.
Latest Patents
One of Ono's latest patents is for a wire conductor designed for harness applications. This innovation involves strands of a copper alloy containing 0.2 to 10 percent by weight of tin, which are braided to form a stranded wire. The conductor has a sectional area ranging from 0.03 to 0.3 mm². After braiding, the stranded wire undergoes heat treatment to maintain its tensile strength at a prescribed level. This wire conductor exhibits a breaking strength comparable to conventional harness wires and is resistant to breakage from impacts. Additionally, it maintains straightness, and the strand ends do not fray upon cutting.
Another significant patent by Ono relates to a method of hot rolling copper and its alloys. This invention has successfully extended the useful life of tools used in hot rolling while improving the surface quality of the rolled products. The method replaces traditional tools made of cemented carbide, die steel, and high-speed steel with tools primarily made of silicon nitride (Si₃N₄). These tools contain various sintering aids and achieve a sintering density of 90% or more, with a Rockwell hardness of 88 or higher.
Career Highlights
Throughout his career, Fumio Ono has worked with prominent companies such as Sumitomo Electric Industries, Limited and Sumitomo Wiring Systems, Limited. His experience in these organizations has allowed him to refine his skills and contribute to innovative projects in the field of materials engineering.
