Introduction

Mika Fujiwara is a notable inventor based in Kariya, Japan. She has made significant contributions to the field of vacuum pump technology, holding 2 patents that showcase her innovative spirit and technical expertise.

Latest Patents

Mika's latest patents include a vacuum pump having main and sub pumps. This invention features a rotary shaft that is rotated by a drive source, incorporating a main pump with a pump chamber and a gas transferring body. The main pump is responsible for transferring gas to an exhaust space, while the sub pump, connected to the exhaust space, partially exhausts the gas. Notably, the sub pump is driven by the same drive source, and its displacement volume is smaller than that of the main pump.

Another significant patent is the roots pump, which consists of a housing, multiple rotary shafts, and a rotor. The design includes a pump chamber formed by the housing, where the rotors on adjacent rotary shafts engage with each other. This innovative configuration allows for efficient gas transfer through a confluent passage and a closed space that corresponds with the paired rotors.
