Title: **Innovations of Toshihiro Susa: A Pioneer in Compressor Technology**

Introduction

Toshihiro Susa, an esteemed inventor based in Osaka, Japan, has made significant contributions to compressor technology. With four patents to his name, Susa has dedicated his career to improving the efficiency and functionality of compressors, particularly in the context of single screw compressors.

Latest Patents

Among Susa's latest innovations is a highly specialized single screw compressor design. This invention features gates of gate rotors designed to engage with the spiral grooves of a screw rotor. In this design, the compressor undergoes distinct operational modes, with specific areas defined for suction and discharge. The suction-side portion extends from the start point of the spiral groove to a position within the compression stroke, while the discharge-side portion is characterized by a minimal clearance between the wall surface and the gate, effectively enhancing compression performance.

Another notable patent involves a method for processing screw rotors. In this design, the first suction-side area is formed within the first side wall surface of a spiral groove. This innovative approach defines a completely-closed state from the start point to just before the compression chamber, thereby optimizing the suction-side area while ensuring it remains thinner than the other portions of the side wall surface. These advancements in design underscore Susa's commitment to engineering efficiency.
