Patents by Inventor Hiromitsu Kuribayashi

Hiromitsu Kuribayashi 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: 6602797
    Abstract: A wafer processing system occupies minimal floor space by using vertically mounted modules such as reactors, load locks, and cooling stations. Further saving in floor space is achieved by using a loading station which employs rotational motion to move a wafer carrier into a load lock. The wafer processing system includes a robot having extension, rotational, and vertical motion for accessing vertically mounted modules. The robot is internally cooled and has a heat resistant end-effector, making the robot compatible with high temperature semiconductor processing.
    Type: Grant
    Filed: April 23, 2002
    Date of Patent: August 5, 2003

  • Patent number: 6379073
    Abstract: A positionable arm composed of multiple member segments connected by an adjustable joint which may be fixedly positioned and repeatedly repositioned. The first member includes an end portion defining a first connector opening and an inner surface defining a chamber. A slideable piston provided in the first member includes a first end and a second end, the first end being adjacent the chamber and creating a seal along the inner surface of the first member. A rotatable connector is received in the first member between the second end of said piston and the end portion of the first member, and a second member is attached to the rotatable connector. To position the arm, a pressurized fluid source supplies compressed air to the chamber, which presses the piston against the rotatable connector, fixedly clamping the connector between the piston and the end portion of the first chamber.

  • Publication number: 20010040230
    Abstract: A gate valve assembly, which may be used to seal a semiconductor processing chamber to isolate the chamber and/or maintain pressure or vacuum therein. The invention includes a gate coupled to a linear axial shaft. The axial shaft is driven using a single action actuator. The gate of the present invention has an inclined surface to the shaft. Because the surface is inclined, the gate can be forced by the movement of the axial shaft against a similarly inclined gate seat surface. The angled surface translates the axial sealing force provided by the axial shaft into a positive lateral sealing force without the need for lateral movement of the gate.
