Title: Yasushige Kashiwabara: Innovator in Compressor Technology and Refrigeration Systems
Introduction
Yasushige Kashiwabara is a notable inventor based in Katsuta, Japan. He has made significant contributions to the fields of compressor technology and refrigeration systems. With a total of 4 patents to his name, his work has had a considerable impact on the industry.
Latest Patents
One of his latest patents is a rotating stall prevention system for compressors. This innovative system includes inlet guide vanes, rotor blades, and stator blades. To prevent rotating stall, baffle vanes capable of having their angles varied are installed upstream of the inlet guide vanes. Actuators are coupled to the baffle vanes to vary their angles, while sensors detect rotating stall conditions inside the flow passage of the compressor. A control unit responds to signals from the sensors to output control signals to the actuators, effectively preventing the rotating stall condition. Additionally, fluid jets may be provided upstream of the inlet guide vanes for the same purpose.
Another significant invention is a refrigerator that comprises a refrigerating cycle with a refrigerant charged. This cycle includes a cooler for a freezing compartment and a closed loop branched from the refrigerating cycle, which contains a cooler for a refrigerating compartment. A heating device in the closed loop supplies the refrigerant through vapor bubble pumping action, controlling the refrigerant flow effectively.
