Title: Innovations of Masahiro Mase
Introduction
Masahiro Mase is a prominent inventor based in Tochigi, Japan. He has made significant contributions to the field of vacuum technology, holding a total of 13 patents. His work focuses on enhancing the efficiency and functionality of vacuum pumps, which are essential in various industrial applications.
Latest Patents
One of Masahiro Mase's latest inventions is a turbo vacuum pump with a magnetically levitated rotor and a control unit. This innovative design features a rotor supported by magnetic bearings within a housing that includes a suction port and an exhaust port. The rotor incorporates a peripheral flow pump stage and a screw pump stage, allowing the exhaust port to maintain pressure at or near atmospheric levels. Before the turbo vacuum pump is activated, the magnetic bearings adjust the rotor's position to remove any reaction products that may have accumulated inside the pump. Additionally, the stator is heated to reduce the binding force of these reaction products, enabling the pump to restart even if the rotor has become locked due to solidified deposits.
Another notable invention is a dry turbo vacuum pump that utilizes a multistage circumferential impeller supported on a shaft. This design integrates a centrifugal pump at the inlet side of the peripheral flow pump, allowing gas to be efficiently discharged to the atmosphere. The combination of the multistage peripheral flow pump and the centrifugal pump enhances the overall performance of the vacuum system.
