Title: Innovations of Nobuo Miyagawa
Introduction
Nobuo Miyagawa is a notable inventor based in Tajimi, Japan. He has made significant contributions to the field of engineering, particularly in the development of advanced degassing apparatuses. With a total of four patents to his name, Miyagawa's work has had a considerable impact on the industry.
Latest Patents
Miyagawa's latest patents include innovative vacuum-suction degassing apparatuses. The first apparatus involves a melt stored in a vessel, where a lower half portion of a rod-formed porous member is immersed in the melt. This porous member is made of a material that is permeable to gas but impermeable to melts, such as molten metal, slag, and matte. When placed in a decompression container, the portion of the porous member above the melt surface is subjected to vacuum or reduced pressure. This allows gases in the melt or gases produced by reactions to pass through the porous member and be released into the vacuum, effectively removing gas-forming components from the melt.
The second apparatus also features a melt stored in a vessel, with a cylindrical degassing member immersed in the melt. The lower half of this member is made of a porous material, serving as a partitioning member. By creating a vacuum or reduced pressure inside the degassing member, gas-producing components in the melt can pass through the partition and be exhausted, separating them from the melt. Additionally, the degassing member can rotate or move, stirring the melt and enhancing the efficiency of gas removal.
Career Highlights
Throughout his career, Miyagawa has worked with various companies, including Tokyo Yogyo Kabushiki Kaisha. His innovative designs and engineering solutions have contributed to advancements in the field of materials processing.
