Title: Kiyoharu Tsujimura: Innovator in Gas Flow Sensor Technology
Introduction
Kiyoharu Tsujimura is a notable inventor based in Kyoto, Japan. He has made significant contributions to the field of gas flow measurement technology. His innovative work has led to the development of a unique gas flow sensor that enhances the accuracy and efficiency of gas flow rate measurements.
Latest Patents
Kiyoharu Tsujimura holds a patent for a gas flow sensor and the method of producing it. This mass gas flow sensor is designed to measure the mass flow rate of gas through a passage. The sensor features a substrate with a streamlined end surface that projects upstream in the passage. It includes upstream and downstream heating resistors formed on the substrate, which are covered by protective films. The circuitry applies current to the resistors, allowing them to heat up, with the gas cooling the upstream resistor more than the downstream one. The circuitry also generates an electrical voltage that responds to the differences in voltage across the resistors, correlating to the mass gas flow in the passage. The manufacturing method involves creating a composite substrate material with hollow portions by joining two integral wafers and applying resistors through photolithography and etching.
