Introduction

Yoshihiko Nakatani is a notable inventor based in Osaka, Japan. He has made significant contributions to the field of gas detection technology. With a total of 4 patents to his name, Nakatani's work focuses on enhancing the sensitivity and reliability of combustible gas sensors.

Latest Patents

Nakatani's latest patents include a "Combustible Gas Detecting Element" and a "Combustible Gas Sensor." The combustible gas detecting element is designed to detect the presence of gases such as methane, ethane, propane, iso-butane, and hydrogen. This element utilizes α-Fe₂O₃ containing a small amount of sulfate ion (SO₄²⁻) to achieve remarkable stability and reliability. The addition of quadrivalent metals like Sn, Zr, or Ti significantly enhances gas sensitivity. Furthermore, the sensitivity to carbon monoxide is improved by incorporating cadmium (Cd) and/or gold (Au). The combustible gas sensor features a sensitive element made from gamma-type ferric oxide (γ-Fe₂O₃) and alpha-type ferric oxide (α-Fe₂O₃), with a microstructure that has an average grain size smaller than 0.5 micrometers and a porosity ranging from 35% to 85%. The sensitivity is further increased by adding tin (Sn) and zinc (Zn) in specific ratios.
