Title: **Innovative Achievements of Inventor Shin Ishihara**
Introduction
Shin Ishihara, an inventive mind hailing from Kasukabe, Japan, has made significant contributions to the field of compressor technology. With a total of two patents to his name, Ishihara has focused on enhancing the performance and durability of rotary compressors through innovative surface treatments and design improvements.
Latest Patents
Shin Ishihara's recent patents showcase his commitment to advancing rotary compressor technology. One of his notable inventions is the "Rotary compressor having oxidizing and nitriding surface treatment." This patent details a sliding member made from an iron-based non-porous material, specifically a vane, which undergoes oxidizing and nitriding to develop a protective layer. Following this treatment, steam is utilized to interact with the oxidized and nitrided layer, resulting in the formation of a porous network structure composed mainly of tri-iron tetroxide. This innovative layer not only enhances the compressor's performance but also contributes to its overall efficiency.
Another significant patent from Ishihara is the "Hermetic rotary compressor with balancing weights." This design features a motor unit placed atop a hermetic housing, with an oil-lubricated compressor unit positioned below. A crankshaft interconnects these units, while a discharging silencer surrounds the lower bearing of the compressor unit. Notably, this hermetic rotary compressor incorporates a lower balancing weight strategically mounted around the crankshaft's lower end, ensuring that it does not interfere with fluid dynamics during operation.
