Title: Maki Narita: Innovator in Cathode Technology

Introduction

Maki Narita is a prominent inventor based in Shiga, Japan. She has made significant contributions to the field of electronic components, particularly in the development of cathode members for electronic tubes. With a total of 3 patents to her name, Narita's work has advanced the efficiency and performance of electronic devices.

Latest Patents

Narita's latest patents include a fabrication method of a cathode member and an electronic tube equipped with this cathode member. This innovative method enhances electron emission capability through a current activation process while maintaining the maximum cathode current. The process involves several steps: first, a nickel powder and a rare-earth-metal oxide powder are mixed to create a first powder mixture. This mixture is then heated in a controlled atmosphere to produce an intermetallic compound. Following this, the first powder mixture is combined with an electron-emissive agent powder to create a second powder mixture, which is sintered using a HIP process to form the cathode member. The resulting cathode member is characterized by its low operation temperature, excellent electron emission distribution, and high current density.
