Title: Yasuo Hasegawa: Innovator in Electrical Discharge Machining

Introduction

Yasuo Hasegawa is a prominent inventor based in Yamanashi, Japan. He has made significant contributions to the field of electrical discharge machining, holding a total of 13 patents. His innovative designs and methods have advanced the capabilities of wire electrical discharge machines.

Latest Patents

Hasegawa's latest patents include a wire electrical discharge machine and an electrical discharge machining method. The wire electrical discharge machine features a gap voltage detector that monitors the voltage across an electrode gap. It also includes a first voltage control unit that applies a first voltage to the electrode gap. A discharge determiner assesses whether the electrode gap is in a discharging state during the application of the first voltage. Additionally, a second voltage control unit supplies machining current through the electrode gap when it is in a discharging state. This design ensures that even after a discharge is induced by the next application of the first voltage, the second voltage control unit prohibits the application of a second voltage to the electrode gap.

Another notable patent is the wire electric discharge machine, which consists of a tank containing a working fluid. It features a table for mounting a workpiece, upper and lower guides that support a wire electrode, and a measurement device that can be detached or moved relative to the upper guide. This device includes a sensor for measuring the workpiece after machining, a plate thickness acquisition unit, a level detection unit, and a level adjustment unit. The level adjustment unit ensures that the working fluid is maintained at an optimal level during the measurement process.
