Patents by Inventor Akihiro Katou

Akihiro Katou 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).

  • Patent number: 10720645
    Abstract: An objet of the invention is to provide a non-aqueous electrolyte secondary battery superior in input-output characteristics even at a low temperature. To achieve the object, hybrid particles (carbon material) satisfying certain conditions, and composed of graphite particles and carbon particles with a primary particle size from 3 nm to 500 nm, preferably as well as amorphous carbon, are used as a negative electrode active material for a non-aqueous electrolyte secondary battery, so that the input-output characteristics of a non-aqueous electrolyte secondary battery at a low temperature can be improved remarkably.
    Type: Grant
    Filed: February 23, 2015
    Date of Patent: July 21, 2020
    Assignee: MITSUBISHI CHEMICAL CORPORATION
    Inventors: Shunsuke Yamada, Nobuyuki Ishiwatari, Akio Ueda, Tooru Fuse, Masakazu Yokomizo, Akihiro Katou

  • Patent number: 6435808
    Abstract: A chip mounting apparatus capable of permitting a chip mounting operation to be executed at an increased speed and ensuring continuous running of the apparatus over a long period of time. The apparatus includes a chip observing camera mounted on the side of a chip mounting head, a lighting unit mounted on the side of the chip mounting head to light a background of a chip hold on a chip suction nozzle of the head, a reflection unit mounted on the side of the chip mounting head to input an image of the chip to the chip observing camera, feeder and stocker sections each adapted to replaceably held a chip storage package therein, and a package replacement mechanism for carrying out replacement of the chip storage package between both sections.
