Title: Tomio Kawakami: Innovator in Gas Sensing Technology
Introduction
Tomio Kawakami is a notable inventor based in Nishio, Japan. He has made significant contributions to the field of gas sensing technology, holding a total of 5 patents. His work focuses on developing sensors that can accurately detect gas compositions, particularly in exhaust systems.
Latest Patents
Kawakami's latest patents include a gas composition sensor and a gas detecting sensor. The gas composition sensor features a gas sensor element whose electric resistance value varies according to the composition of exhaust gases. It includes a pair of electrodes that detect this resistance value, allowing for precise sensing of exhaust gas composition. Additionally, a layer of material that is substantially impervious to gases surrounds the electrodes, enhancing the sensor's functionality.
The gas detecting sensor is designed to accurately measure the partial pressure of oxygen gas in exhaust gases, unaffected by environmental temperature changes. This sensor comprises a ceramic base member and a film-shaped gas sensing element that responds to the partial pressure of oxygen. It also includes a temperature sensing element with a temperature coefficient of resistance that matches that of the gas sensing element. This innovative design ensures reliable readings by maintaining both elements within a consistent temperature range.
