Patents by Inventor Munetaka Takeuchi

Munetaka Takeuchi 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: 7231332
    Abstract: An apparatus and method for simulating phenomena of a combined particle formed of substrate particles and adsorbate particles. The simulated phenomena can include, for example, crystal growth, crystal surface adsorption and surface damage. The apparatus includes a kinetic condition setting unit and a particle motion computing unit. The kinetic condition setting unit sets information for defining kinetic conditions of the adsorbate particles. The particle motion computing unit generates the adsorbate particles in accordance with the information set by the kinetic condition setting unit and computes motion of the generated adsorbate particles, to simulate phenomena of the combined particle.
    Type: Grant
    Filed: July 8, 1997
    Date of Patent: June 12, 2007
    Assignee: Fujitsu Limited
    Inventors: Munetaka Takeuchi, Nozomu Kamiya, Hiromi Hayashi, Makoto Ishitobashi

  • Patent number: 5664083
    Abstract: A graphic display apparatus for rotating a three-dimensional figure about the three axes of the Cartesian coordinate system has a graphic information storing unit for storing graphic information of a three-dimensional object to be displayed, a rotative action indicating unit for indicating rotative actions to rotate the three-dimensional object being displayed about the three axes, a display coordinate calculating unit for calculating coordinates of the three-dimensional object after it is rotated, a rotational angle calculating unit for calculating rotational angles of the three-dimensional object after it is rotated, and a display unit for displaying the three-dimensional object after it is rotated and the calculated rotational angles. The rotational angle calculating unit calculates the rotational angles of the three-dimensional object rotated by the rotative action, as rotational angles from the initial state of the three-dimensional object in a predetermined sequence of three rotative actions.
