Latest Patent Applications
1. **OXYGEN SENSOR ELEMENT AND METHOD FOR MANUFACTURING SAME** - This application describes an oxygen sensor element designed to achieve electric power savings without compromising sensor characteristics. The structure features a ceramic sintered body as a sensing layer made from a composition of LnBaCuO, which is covered with heat insulating layers. The heat insulating material also consists of LnBaCuO, enhanced with 20 mol % of LnBaCuO. This design allows the sintering behavior of the heat insulating layers to closely match that of the sensing layer, preventing layer separation and cracks. The sandwich structure of the oxygen sensor element reduces heat dissipation from the sensing layer, facilitating electric power savings.
2. **RESISTIVE OXYGEN GAS SENSOR AND OXYGEN SENSOR DEVICE** - In this application, the resistive oxygen gas sensor includes an oxygen gas detection member that primarily consists of a semiconductor material with a composition formula represented by RE(Ba, RE)CuO. Here, RE denotes a rare earth element, with specific ranges for x and y values. This innovative approach aims to enhance the efficiency and effectiveness of oxygen detection.
Conclusion
Tomoichiro Okamoto's work in the field of oxygen sensors showcases his commitment to innovation and efficiency. His latest patent applications reflect a deep understanding of materials and their applications in sensor technology.
