Title: Hiroji Tsujimura: Innovator in Pyrometry
Introduction
Hiroji Tsujimura is a notable inventor based in Osaka, Japan. He has made significant contributions to the field of pyrometry, with a focus on developing advanced temperature measurement technologies. With a total of 3 patents to his name, Tsujimura's work has had a considerable impact on various industries.
Latest Patents
One of Tsujimura's latest inventions is a pyrometer that includes a light source capable of emitting light at two wavelengths to a target for measurement. This device features a light measuring member that assesses the light source and provides output signals representative of those wavelengths. Additionally, a second light measuring member captures light reflected by the target, while a third member measures the intensity of light radiated by the target. The temperature is calculated based on the minimum difference between the assumed radiation intensity and the measured intensity. Another innovative pyrometer developed by Tsujimura calculates the temperature of a target using a light-emitting device that emits reference light at three wavelengths. This design allows for accurate temperature calculations even for semi-transparent objects by incorporating measurements of transmitted, reflected, and radiated light.
