Title: The Innovations of Takao Hoshi
Introduction
Takao Hoshi is a notable inventor based in Fuji, Japan. He has made significant contributions to the field of engineering, particularly in the development of technologies related to compressors and brushless motors. With a total of 4 patents to his name, Hoshi continues to push the boundaries of innovation.
Latest Patents
Hoshi's latest patents include a method for starting a brushless motor for driving a compressor. This method involves controlling the start of a refrigerant-circulating compressor driven by a brushless motor in a refrigerating cycle. The brushless motor is initiated through an asynchronous forced commutation operation without relying on rotor position detection signals. Once the rotor position detection signals are detected a predetermined number of times due to synchronous commutations, the operation shifts to a synchronous commutation starting method using these signals. Another significant patent is for a fluid compressor with a selector valve. This invention features a closed casing and a compression mechanism that compresses low-pressure fluid and discharges high-pressure fluid. The selector valve, which is rotatable within the casing, changes the passage of the high-pressure fluid and switches the low-pressure fluid flow to communicate with the compression mechanism.
