Patents by Inventor Norihiko Hatano

Norihiko Hatano 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: 8128768
    Abstract: The present invention provide an apparatus for manufacturing a bonded substrate that suppresses a defect in the bonded substrate. When the pressure in a vacuum chamber is at the atmospheric level, upper and lower chuck units respectively attract substrates through vacuum. When the vacuum chamber is depressurized, each chuck unit electrostatically attracts the associated substrate. During the depressurization of the vacuum chamber, the pressure for attracting each substrate to the associated chuck unit is controlled to be equal to the pressure in the vacuum chamber. This prevents each substrate from falling from or moving relative to the associated chuck unit. The first and second substrates are thus bonded together as accurately aligned.

  • Patent number: 4843292
    Abstract: A direct drive motor system for controlling driving of the joints of a multi-jointed robot, comprising a motor portion, a rotation detecting portion, a position control portion, a speed control portion, a driving circuit and a tuning portion, wherein the motor portion is of an inductor type, the rotation detection portion uses an optical rotary encoder or magnetic resolver, and the position control portion is arranged to control in a feedback manner the rotational position of the motor with a tertiary servo system with software. The system's driving circuit has a feedback control loop for the current of the motor coil, and a detection circuit for the current includes a small signal isolator. The tuning portion tunes the servo systems of the speed control portion and the position control portion. As a result, the system simultaneously satisfies various requirements of such a direct drive motor.
