Latest Patents

Yonemaochi’s patent, “Electric Discharge Machining Method and Apparatus for Machining a Microshaft,” describes a system that shapes a microshaft using electrical discharge between the shaft and a conductive wire serving as the working tool.

The apparatus supports the microshaft so it can rotate around its axis and move vertically. The wire travels along its own axis and can move toward or away from the shaft. A control unit coordinates these movements, positioning the wire at a set horizontal distance from a reference point while the shaft rotates and moves vertically. This process machines the shaft to a specified diameter and produces a section of a controlled length.

Career Highlights

Yonemaochi’s documented contribution focuses on precision machining, particularly the controlled shaping of small-diameter shafts. The patent describes coordinated motion and electrical discharge as a way to achieve defined dimensions.

Collaborations

The supplied information identifies Takeshi Mizutani and Akemi Tanaka as Yonemaochi’s coworkers. It does not specify their roles in the patent or the extent of their collaboration.

Conclusion

Katsutoshi Yonemaochi’s recorded patent highlights an approach to microshaft machining that combines electrical discharge with precise control of the workpiece and wire.
