Title: Innovations of Tatsuo Kawasaki
Introduction
Tatsuo Kawasaki is a prominent inventor based in Chiba, Japan. He has made significant contributions to the field of materials science, particularly in the development of advanced stainless steels and far-infrared emitters. With a total of 8 patents to his name, Kawasaki's work has had a substantial impact on various industrial applications.
Latest Patents
Kawasaki's latest patents include innovations in martensitic stainless steels for seamless steel pipes. These steels are designed to enable the fabrication of high-strength seamless steel pipes suitable for use in oil-well pipe and pipeline tubing. The production process, utilizing a Mannesmann plug mill or mandrel mill, minimizes defects during manufacturing. The heat workability of these steels is significantly enhanced by controlling the phosphorus and sulfur levels to no more than 0.020% and 0.003% by weight, respectively.
Another notable patent involves a far-infrared emitter characterized by high emissivity and corrosion resistance. This emitter is created through an oxidizing heat treatment of stainless steel containing 20-35% chromium and 0.5-5.0% molybdenum. The process forms an oxidized surface film that enhances its performance. Additionally, a high-emissivity far-infrared emitter is produced by roughening the surface of stainless steel and subjecting it to a similar heat treatment.
