Title: Tomoko Uchida: Advances in Resin Materials and Solid Electrolytic Capacitors.

Introduction

Tomoko Uchida is an inventor based in Ome, Japan, whose work includes resin materials and solid electrolytic capacitor technology. Her listed portfolio includes 3 patents. She is associated with Shoei Chemical Inc.

Latest Patents

Uchida’s listed inventions include “Method for Producing Binder Resin, Method for Producing Resin Composition, Binder Resin, and Resin Composition.” The method reacts a cellulose derivative and polyvinyl acetal with a bonding agent containing at least two functional groups capable of reacting with their hydroxyl groups. It specifies a bonding-agent content at least twice the molar quantity of whichever starting material—polyvinyl acetal or cellulose derivative—is present in the greater molar amount. The resulting binder resin is intended for coating pastes, including conductive pastes, and can improve coating-film smoothness and density.

Another listed invention is “Solid Electrolytic Capacitor Element, Method for Manufacturing Same, and Conductive Paste.” It addresses resistance to equivalent series resistance (ESR) deterioration caused by thermal shock while aiming to maintain good initial ESR characteristics and reduce variation in ESR changes. The capacitor element includes an anode body with a dielectric layer, a solid electrolyte layer, a carbon layer, and a conductive layer. The carbon and conductive layers contain resin components with hydroxyl groups, and the invention specifies a limited difference between the hydrogen-bonding component values of their surfaces.
