Title: Michihiro Hatanaka: Innovator in Field Emission Technology

Introduction

Michihiro Hatanaka is a prominent inventor based in San Jose, CA, known for his contributions to field emission technology. He holds a total of 4 patents, showcasing his innovative spirit and technical expertise in the field.

Latest Patents

Hatanaka's latest patents include a field emission device and a field emission method. In his field emission device, an emitter and a target are arranged to face each other within a vacuum chamber. A guard electrode is positioned at the outer circumferential side of the electron generating portion of the emitter. The emitter is supported movably in both end directions of the vacuum chamber by an emitter supporting unit, which is operated by an operating unit connected to it. This design allows for the adjustment of the distance between the electron generating portion of the emitter and the target, enabling field emission to be performed with the emitter's position fixed.

Another significant patent is his electric field radiation device and regeneration processing method. In this invention, the emitter and target are also arranged to face each other in a vacuum chamber, with a guard electrode provided at the outer circumferential side of the electron generating portion of the emitter. The guard electrode is supported movably by a guard electrode supporting unit. This allows for the regeneration process of the guard electrode, where it can be moved to a separate position to suppress field emission, followed by a voltage application to perform discharge and regeneration.
