Title: Hiroshi Fujii: Innovator in Chemical Separation and Motion Control

Introduction

Hiroshi Fujii is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the fields of chemical separation and motion control. With a total of 3 patents, his work showcases innovative approaches to complex engineering challenges.

Latest Patents

One of Fujii's latest patents is a process for separating 2,6-dimethylnaphthalene from a mixture. This process involves mixing the mixture with 2,4,7-trinitro-9-fluorenone to form a complex. The solid matter containing this complex is then separated, and the solid is decomposed to collect an oil rich in 2,6-dimethylnaphthalene. This method allows for high selectivity in the separation process, and the 2,4,7-trinitro-9-fluorenone can be easily recovered and reused. Another significant invention is a linear step motor type driving apparatus designed for driving a longitudinally-moving vertically-suspended body. This apparatus includes a moving element in a rail channel, equipped with an electromagnet that operates using discrete pulses or continuous current. The electromagnet's coils generate a magnetomotive force that facilitates the movement of the element within the channel.
