Patents by Inventor Tetsuya Takada

Tetsuya Takada 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: 10029807
    Abstract: A spacecraft 10 includes wings 11 or an airframe 12 which generates lift in an atmosphere 2, a thruster 14 which accelerates or decelerates rotating speed in an orbit, an attitude controller 16 which controls an attitude of the airframe 12, and an orbital plane controller 18 which controls the orbital plane change. The orbital plane controller causes the spacecraft 10 to enter the earth's atmosphere 2 within a pre-change orbital plane Fb (A?B?C), changes the orbital plane by using the lift of the wings 11 or airframe 12 in the earth's atmosphere 2 (C?D?E), and then lifts the spacecraft 10 up to the post-change orbital altitude (E?F).
    Type: Grant

    Date of Patent: July 24, 2018
    Assignee: IHI AEROSPACE CO., LTD.

  • Patent number: 7061964
    Abstract: An electrostatic levitation furnace is improved by providing three pairs of electrodes opposed to each other respectively on three axes perpendicularly intercepting each other at a position where the sample is to be levitated in the vacuum chamber, and disposing a plurality of access ports, which are directed to the position of the sample, to the vacuum chamber tree-dimensionally, whereby the accessible direction against the sample is diversified, it becomes possible to improve the degree of freedom in distribution of various apparatuses and easily cope with increase of apparatuses.
