Title: Jiro Arima: Innovator in Measurement Technology
Introduction
Jiro Arima is a notable inventor based in Osaka, Japan. He has made significant contributions to the field of measurement technology, holding a total of 5 patents. His innovative work has advanced the capabilities of various measuring instruments, particularly in temperature and color measurement.
Latest Patents
One of Arima's latest patents is a pyrometer designed to measure temperature accurately. This pyrometer includes a light source that emits light at two wavelengths to a target. A light measuring member captures the emitted light and provides output signals for both wavelengths. Additionally, a second light measuring member measures the light reflected by the target, while a third member assesses the intensity of the light radiated by the target. The temperature is calculated based on the difference between the assumed radiation intensity and the measured intensity.
Another significant patent is a color measuring apparatus that utilizes a flash lamp for color temperature measurement. This apparatus features a flash tube that emits light to a target in two short periods. A detector measures the light amounts from the target during these periods, while a receiver detects reference light amounts. The system evaluates the flash light and generates a compensation signal to calculate the target's characteristic value under ideal light conditions.
