Title: Kazuo Okino: Innovator in Gas Sensing Technology

Introduction

Kazuo Okino is a notable inventor based in Hyoogo, Japan, recognized for his contributions to gas sensing technology. He holds two patents that showcase his innovative approach to developing advanced sensors for detecting exhaust gases.

Latest Patents

One of Okino's latest patents is an exhaust gas sensor and the process for producing it. This sensor incorporates BaSnO.sub.3 and is designed to be free of segregation while achieving an acid-base strength of at least 6.8, as determined with Hammett's indicator. The presence of elements such as silicon (Si) and boron (B) can reduce the acid-base strength, while the addition of magnesium (Mg) or calcium (Ca) can enhance it. The desired BaSnO.sub.3 is prepared by precipitating hydrous crystals while preventing the introduction of Si and B, particularly by using a synthetic resin-lined container. The process also involves adding Mg or Ca to the precipitate and thermally decomposing it. Another significant patent is for a gas detecting device that stores a constant sensor output as a reference. It detects gas evolution by monitoring variations in the sensor output from this stored reference.
