Title: The Innovations of Inventor Makiko Kawada

Introduction

Makiko Kawada is an esteemed inventor based in Chiyoda-ku, Japan. She has contributed significantly to the field of electrical engineering, holding two patents that reflect her innovative approach to solving complex engineering challenges.

Latest Patents

One of her latest patents is for a **Gas Insulated Apparatus**. This invention addresses the issue of hydrogen fluoride gas generation when electric discharging occurs in a gas-insulated environment filled with sulfur hexafluoride. To combat the abrasion of glass fiber reinforced plastics, Kawada developed a solution involving organic fiber woven cloth, such as aramid fiber. This cloth, known for its hydrogen fluoride resistance and mechanical toughness, is wrapped around the surface of the glass fiber reinforced plastics. A thermosetting resin is then impregnated into the weave patterns and heat cured, resulting in an abrasion-preventing protection layer that remains intact without peeling off.

Kawada's second patent is for a **Gas Insulated Breaking Device**. This device features open/close elements, including a puffer cylinder that compresses the insulation gas to extinguish arcs. A novel design incorporates both soft and hard plating films on the slide contact portions of the components. The puffer cylinder has a relatively soft plating film, while the contact finger is equipped with a relatively hard plating film. This dual-layered approach, featuring silver plating, enhances the durability and functionality of the device, promoting greater efficiency in electrical contacts.
