Title: Innovations of Katsunori Yamada
Introduction
Katsunori Yamada is a prominent inventor based in Nagoya, Japan. He holds a total of 13 patents, showcasing his significant contributions to the field of thermistor materials and temperature sensing technologies. His work has had a considerable impact on various applications, particularly in temperature measurement and control.
Latest Patents
One of his latest patents is focused on a thermistor material designed for short-range low-temperature use. This innovative material comprises a matrix made of nitride-based and/or oxide-based insulating ceramics, along with conductive particles of α-SiC. These conductive particles are strategically dispersed in the grain boundary of each crystal grain to create an electric conduction path. Additionally, the thermistor material incorporates boron and second conductive particles, which are either metals or inorganic compounds, ensuring a specific electric resistance value at room temperature that is lower than that of α-SiC and has a melting point exceeding 1700°C. The production process involves mixing various powders and sintering them to achieve desired resistance characteristics.
Another significant patent involves a temperature sensing element that includes a thermistor made from Si-based ceramics. This element features metal electrodes that are bonded to the thermistor's surfaces. The electrodes contain chromium and a metal element α, which has a higher silicon diffusion coefficient than chromium. This design allows for the formation of diffusion layers at the bonding interface, enhancing heat resistance and bonding reliability. The resulting temperature sensor is capable of accurate temperature detection across a wide range, specifically from -50°C to 1050°C.
