Title: **Fumio Kogiku: A Trailblazer in Amorphous Alloy Technology**
Introduction
Fumio Kogiku, an innovative inventor based in Chiba, Japan, has made significant contributions to the field of amorphous alloys. With an impressive portfolio of eight patents, Kogiku's work focuses on developing advanced materials that enhance the performance of electric power transformers and other industrial applications.
Latest Patents
Among Kogiku's latest patents is the development of a **Low Boron Amorphous Alloy and Process for Producing Same**. This invention describes an amorphous alloy with a boron content of approximately 6 to 10 atomic percent, cast into a plate with a thickness between 15 to 25 micrometers. The surface roughness of this plate is maintained at around 0.8 micrometers or less, enhancing its applicability in various sectors.
Another significant patent is the **Wide Iron-Based Amorphous Alloy Thin Strip and Method of Making the Same**. This invention details a wide amorphous alloy thin strip, exceeding 70 mm in width, specifically designed as an iron core for electric power transformers. The strip is composed of an Fe-Si-B-C amorphous alloy, with a critical innovation that prevents dispersion of the amorphous structure in the width direction. This quality is achieved by adding manganese or by casting in an atmosphere with a carbonic acid gas content of about 40 vol % or more, effectively controlling the strip's surface roughness to an average of about 0.7 micrometers or less.
