Title: Makoto Fujikawa and His Mechanical Abrasion Invention.

Introduction

Makoto Fujikawa is an inventor associated with Omihachiman, Japan. His patent work addresses how to hold a workpiece securely during mechanical abrasion, particularly when substantial material must be removed.

Latest Patents

The available information lists one patent for Fujikawa: Work Holding Member for Mechanical Abrasion, Abrading Method, and Abrading Machine. The invention describes a two-part work-holding arrangement. A first holding member receives the workpiece and transmits external drive force, while a second holding member is placed over it. After a predetermined amount of material has been removed, the second member is taken away, and abrasion continues with the first member alone until the workpiece reaches its target thickness. This staged approach is intended to help prevent damage during heavy stock removal. The patent record reports 1 patent.

Career Highlights

Fujikawa’s documented patent contribution focuses on improving workpiece support and abrasion control. The described method combines a change in the holding arrangement with the progression of the abrasion process, allowing the workpiece to be held differently as it approaches its target thickness.

Collaborations

Hideo Ohkuma and Tomohito Johnai are identified as Fujikawa’s coworkers. The available information does not specify their roles in the patent or the nature of their collaboration.

Conclusion

Makoto Fujikawa’s listed invention presents a staged work-holding method designed to support safer mechanical abrasion and reduce the risk of workpiece damage during substantial material removal.
