Introduction

Yasuo Tsumita is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of materials science, particularly in the production of niobium powder for capacitors. With a total of 2 patents, Tsumita's work has advanced the technology used in capacitor manufacturing.

Latest Patents

Tsumita's latest patents focus on a production process for niobium powder. The process involves grinding a niobium hydride or niobium hydride alloy at temperatures ranging from -200 to 30°C in the presence of a dispersion medium. This method yields a niobium powder with low oxygen content, which is essential for high-performance capacitors. The niobium powder is then granulated to create a product with an average particle size of 10 to 500 micrometers. Following this, the powder is sintered to form a solid body. A capacitor is then fabricated by applying a dielectric material to the surface of the sintered body and adding an electrode, resulting in a capacitor with excellent LC characteristics.
