Title: Masaetsu Matsumoto: Innovator in Particle Measurement Technology

Introduction

Masaetsu Matsumoto is a notable inventor based in Sendai, Japan. He has made significant contributions to the field of particle measurement technology, holding three patents to his name. His innovative work focuses on developing advanced apparatuses for investigating particles in fluids.

Latest Patents

Matsumoto's latest patents include an apparatus for investigating particles in a fluid. This invention utilizes a flow cell that allows fluid to flow past a sensor, which receives light from a continuous light emission system. When the sensor detects a change in light, a particle detector is triggered, activating a pulse generator and an intermittent light emission system. This setup illuminates the flow cell, enabling a CCD camera to photograph the particles. The images captured are then analyzed by an image processor to derive accurate particle concentration measurements. To enhance accuracy, a concentration compensator modifies the initial measurements based on the analysis. Additional analysis can be performed by adjusting the magnification of the CCD camera or selecting specific particles for examination.

Another significant patent is the flow cell apparatus designed for measuring particles suspended in a liquid. This apparatus includes a sample liquid supply device, a sheath liquid supply device, and a flow cell with a transparent measuring portion. The nozzle within the flow cell ensures a stable sample flow of fixed width, even at high velocities, allowing for efficient and accurate particle photography.
