Title: Innovations of Yoshio Iida in Reducing Gas Sensors
Introduction
Yoshio Iida is a notable inventor recognized for his contributions to the field of gas sensing technology. He is associated with Matsushita Electric Industrial Co., Ltd., where he has developed innovative solutions that enhance the sensitivity and stability of gas sensors.
Latest Patents
Yoshio Iida holds a patent for a reducing gas sensor and a method of producing the same. This invention features a gas-sensitive element made of gamma-ferric oxide (γ-Fe₂O₃), along with a pair of electrodes and a heater element. The gamma-ferric oxide is presented in various forms, including a thin film, a plate, or a thin surface layer on a sintered plate of alpha-ferric oxide (α-Fe₂O₃). The method of producing this sensor involves firing γ-Fe₂O₃, γ-FeOOH, or Fe₃O₄ powder on a substrate and applying electrodes and a heater element. Alternatively, it includes sintering α-Fe₂O₃ and reducing it to magnetite, followed by oxidizing it at the surface to form γ-Fe₂O₃ as the gas-sensitive element. The sensor demonstrates a sensitivity (Rₐ/R₍₍G₎₎) ranging from 10 to 130 degrees at 270 degrees Celsius in an atmosphere containing 0.1 to 1 percent by volume of propane gas.
