Title: The Innovations of Tadakazu Oohashi

Introduction

Tadakazu Oohashi is a notable inventor based in Omiya, Japan. He has made significant contributions to the field of materials science, particularly in the development of cutting tools. His innovative work has led to the creation of a unique diamond-based ultra-high-pressure-sintered material.

Latest Patents

Oohashi holds a patent for a cutting tool blank formed from a composition that includes 0.1 to 20 wt % of BaCO3 and/or MgCO3, and/or 0.05 to 10 wt % of CaMg(CO3)2 or CaCO3. The balance of the material is primarily diamond, which is heated and maintained at a temperature of 800°C to 1400°C in a vacuum. This process facilitates a chemical reaction that transforms the aforementioned compounds into 0.05 to 13% of BaO and/or MgO and/or 0.02 to 5% of CaO, resulting in a cutting tool with a diamond matrix that has finely and uniformly distributed BaO, MgO, and/or CaO.
