Latest Patents

Two of Shirai's most recent patents include the **Method of Manufacturing Ceramic Sheet** and the **Method of Manufacturing Gas Sensing Element**. The manufacturing method for the ceramic sheet involves blending ceramic powder, a binder, and a plasticizer in a slurry. This slurry is then formed into unfired green sheets with a porosity greater than 5%. Following the application of pressure of 10 MPa at temperatures above 60°C, paste is printed on the surfaces of these sheets. In the gas sensing element patent, a combination of layers is assembled—comprising a shielding layer, a porous diffusion resistance layer, and the unfired green sheets for the sensing layer. This stacked ceramic body undergoes firing to produce a functional gas sensing element.

Shirai also developed a **Sealing Structure of Ceramic Heater**, designed to enhance the durability of ceramic heaters used in gas sensors. This ceramic heater is equipped with electrical conductors that are hermetically sealed to prevent corrosion and ensure continuous operation, thus improving reliability.
