Title: **Innovations of Dai Kobuchi: A Pioneer in Rare-Earth Magnet Manufacturing**

Introduction

Dai Kobuchi is an innovative inventor based in Nagoya, Japan, known for his contributions to the field of rare-earth magnets. With two notable patents to his name, Kobuchi has been instrumental in developing advanced manufacturing methods that enhance the performance and efficiency of these crucial materials.

Latest Patents

Kobuchi's latest patents focus on innovative manufacturing methods for rare-earth magnets. The first patent outlines a comprehensive manufacturing method that entails creating a sintered body through pressing a magnetic powder specific to rare-earth magnets. This sintered body is then placed in a plastic working mold, where hot plastic working is performed. This technique aims to impart anisotropy to the sintered body, facilitating the production of high-performance rare-earth magnets with a cuboid shape featuring at least one recessed side face.

The second patent describes a method for producing a rare-earth magnet precursor. This method involves a dual hot working process. In the first hot working stage, one side surface of the sintered body is constrained to minimize deformation, while the opposite side surface is allowed to deform. Subsequently, the second hot working stage redefines the states of these surfaces, enhancing the final production of the rare-earth magnet through a unique interplay of constrained and unconstrained conditions.
