Title: Kiyomi Yasuhara: Innovator in Amorphous Metal Filaments

Introduction

Kiyomi Yasuhara is a notable inventor based in Kyoto, Japan. She has made significant contributions to the field of materials science, particularly in the development of amorphous metal filaments. With a total of two patents to her name, Yasuhara's work has implications for various industrial applications.

Latest Patents

Yasuhara's latest patents focus on the production of amorphous Co-based metal filaments. These filaments have a circular cross-section and are composed mainly of an alloy of Co-Si-B or Co-Me-Si-B, where Me represents a selection of metals including Fe, Ni, Cr, Ta, Nb, V, Mo, Mn, W, and Zr. The production process involves jetting the alloy into a rotating member filled with a cooling liquid through a specially designed spinning nozzle. This method allows for the cooling and solidification of the molten alloy, resulting in a filament that is wound continuously on the inner walls of the rotating member. The resulting amorphous metal filament is known for its corrosion resistance, toughness, and high electromagnetic characteristics, making it highly useful in electric and electronic parts, composite materials, and fibrous materials.
