Title: Yuuichi Yanagase: Innovator in Compressor Technology
Introduction
Yuuichi Yanagase is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of compressor technology, holding a total of 17 patents. His innovative designs focus on improving the efficiency and performance of compressors, particularly in reducing oil flow and enhancing corrosion resistance.
Latest Patents
One of Yanagase's latest patents is for a scroll compressor. This design includes a revolving scroll, a fixed scroll, an autorotation preventing mechanism, a frame, and a crank shaft with an eccentric pin portion. The crank shaft is equipped with a flange portion that is larger than the diameter of the eccentric pin portion. A balance weight is mounted on the flange portion, and a sealing member ensures proper sealing between the revolving scroll and the flange. Additionally, a thrust bearing is arranged between the frame and the flange portion. This innovative scroll compressor reduces the amount of oil flowing into a back pressure chamber, thereby improving its overall performance.
Another notable patent is for an oil-free screw compressor and a method of manufacturing the casing used for it. The invention aims to provide a compressor with a corrosion-resistant film on the surface of a casing that has a complicated shape. The compressor pumps gas in a compression chamber formed by a casing made of cast iron. A layer composed of a mixture of iron nitride and a compound of iron, nitrogen, and carbon, along with an oxide layer made of triiron tetraoxide, is formed on the casing's surface. This design enhances the corrosion resistance of the casing, suppressing rust generation and minimizing galling or sticking caused by rust.
