Title: Inventor Masakatsu Nagata: Innovations in Electrode Formation and Heat Transfer Technologies

Introduction

Masakatsu Nagata is a notable inventor based in Tokyo, Japan. He is recognized for his contributions in the field of electronic components and heat transfer technologies. With a remarkable portfolio that includes two patents, Nagata has significantly advanced processes related to projection electrodes and heat pipes.

Latest Patents

Nagata's latest inventions showcase his ingenuity and technical expertise. His first patent details a method of forming a projection electrode. In this process, a dry-film resist, typically a photosensitive film, is applied over an electroconductive material on a wiring board. After masking the areas not designated for projection electrode formation, the wiring board undergoes light exposure. Following mask removal, a development process eliminates the dry-film resist from regions outside the intended electrode area. The electroconductive material is then etched, resulting in a projection electrode characterized by a bump with a pointed tapering end in vertical cross-section. Finally, a plated layer is formed through a plating process, completing the projection electrode.

His second patent pertains to a heat pipe and the process for manufacturing it. This innovative heat pipe transfers heat as the latent heat of evaporation from a heating portion of a container to a lower temperature radiating portion. By heating the container, the working fluid evaporates and the vapor is conveyed to the radiating portion, where it condenses. The container is uniquely designed into a flattened hollow shape, consisting of a flat heating portion and a larger area radiating portion, connected by side wall portions, creating an efficient thermal transfer mechanism.
