Patents by Inventor Masayori Suwa

Masayori Suwa has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Mass spectrometry and mass spectroscope
    Patent number: 7642512
    Abstract: A magnetic field gradient is generated in a space, and a microparticle is flied downward in the space, thereby applying a magnetic force from the magnetic field gradient onto the microparticle. Then, a velocity and an acceleration of the microparticle due to the magnetic force are measured, thereby measuring a mass of the microparticle on the measured velocity and a magnetic susceptibility of the microparticle.
    Type: Grant
    Filed: September 1, 2006
    Date of Patent: January 5, 2010
    Assignee: Osaka University
    Inventors: Hitoshi Watarai, Hideaki Monjushiro, Katsuya Watanabe, Masayori Suwa, Mariko Arase
