Title: Innovations of Hideki Yazawa
Introduction
Hideki Yazawa is a notable inventor based in Saitama, Japan. He has made significant contributions to the field of rotary compressors, holding a total of 2 patents. His work focuses on enhancing the efficiency and durability of compressor technology.
Latest Patents
Yazawa's latest patents include a rotary compressor and a blade tip structure. The rotary compressor features a compression chamber defined by a rolling piston that is eccentrically rotated in a cylinder. This design includes a blade that slides in a groove formed in the cylinder, ensuring that the tip contacts the outer-peripheral surface of the rolling piston. This innovative approach prevents abnormal wear in the contact portion between the rolling piston and the blade. The blade's contact surface is designed to have a curvature of substantially zero, forming a flat surface at critical rotation angles. Additionally, a material with a lower elastic modulus than that of the rolling piston is utilized for the blade, enhancing its self-lubrication properties.
Another patent involves an iron-base alloy specifically designed for rotary type compressors. This alloy consists of various elements, including carbon, silicon, manganese, and vanadium, making it suitable for use with hydrofluorocarbon refrigerants. The inclusion of boron further improves the alloy's performance.
