Introduction

Yoshihiko Hirata is a notable inventor based in Mobara, Japan. He has made significant contributions to the field of manufacturing vacuum hermetic vessels and has been awarded two patents for his innovative techniques. His work reflects a deep understanding of materials and engineering principles.

Latest Patents

Hirata's latest patents include a "Method of manufacturing vacuum hermetic vessels" and a "Vacuum airtight device having NbN electrode structure incorporated." The first patent describes a process where plural exhaust holes are formed in the first main substrate at various positions. A second main substrate is superposed over the first, and the two substrates are hermetically sealed. They are then cut at predetermined positions to create individual vessels, with lead-out electrodes formed on both substrates. The vessels are evacuated and sealed using exhaust tubes. The second patent involves a field emission element that includes an electrode structure made of a thin film with increased adhesive strength. A thin film of niobium nitride (NbN) is formed on a glass substrate, exhibiting sufficient adhesive strength to prevent peeling during the etching process.
