Title: Toshihiro Shimakawa: Innovator in Particle Separation Technologies

Introduction

Toshihiro Shimakawa is a notable inventor based in Yamaguchi, Japan. He has made significant contributions to the field of particle separation technologies, holding a total of 6 patents. His innovative methods have the potential to enhance various industrial processes.

Latest Patents

One of his latest patents is a method and apparatus for the separation of mixtures. This invention applies a gradient magnetic field to a paramagnetic supporting liquid containing a mixture of first and second particles. The first particles have a lower magnetic susceptibility than the liquid, while the second particles have a higher magnetic susceptibility. By applying a gradient magnetic field in a separation tank equipped with a magnetic filter, the first particles can float in the liquid due to the magneto-Archimedes effect. This allows them to be gathered in a specific region, while the magnetic filter captures the second particles.

Another significant patent by Shimakawa involves a method and apparatus for separating mixtures using a countercurrent classification technique. This invention is particularly useful for separating mixtures with minimal differences in density and particle diameter. The separation tube, which has an inverted-conical or pyramidal shape, allows for the upward flow of fluid, introducing the mixture into the tube. A gradient magnetic field is then applied, enabling effective separation of the first and second particles based on their differing magnetic susceptibilities.
