Title: Masayoshi Kanno: Innovator in Fuel Cell Technology and Wear Resistant Materials

Introduction

Masayoshi Kanno is a prominent inventor based in Kitaibaraki, Japan. He has made significant contributions to the fields of fuel cell technology and wear resistant materials. With a total of 9 patents to his name, Kanno continues to push the boundaries of innovation in his field.

Latest Patents

One of Kanno's latest patents is a fuel cell that utilizes organic fuel. This innovative fuel cell can control an optimum fuel concentration according to its output without the need for a sensor to measure the fuel concentration. It employs a liquid organic compound as fuel and includes a membrane-electrode assembly, a passage for fuel or oxidant flow, and a fuel supply unit that can intermittently change the rate of fuel supply. A computation processor measures the voltage or output of the fuel cell, computes the fuel supply rate, and adjusts it accordingly. This design allows for easy control of the optimum fuel concentration based on output variations.

Another notable patent is related to a wear resisting sintered alloy and its production. This material, which contains no cobalt, is designed for the sliding portion of a control rod driving mechanism in nuclear plants. It aims to reduce exposure doses from cobalt elution while ensuring smooth operation under high loads. The control rod driving mechanism incorporates rollers and pins made from a wear resisting alloy, which consists of coarse hard phase particles dispersed in a softer matrix.
