Patents by Inventor Vlad Zila

Vlad Zila 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).

  • Tilt and swivel chair and mechanism therefor
    Patent number: 7547067
    Abstract: The invention provides a chair and mechanism to permit occupant swivelling, bouncing, and tilting. The chair mechanism also provides tilt limitation using a keyhole tilt delimiter. The keyhole orientation follows rotation of the chair. A bearing assembly (preferably using race bearings) facilitates simultaneous swivelling and tilting.
    Type: Grant

  • Semiconductor processing apparatus having lift and tilt mechanism
    Patent number: 7002698
    Abstract: A lift/tilt assembly for use in a semiconductor wafer processing device is set forth. The lift/tilt assembly includes a linear way comprising a fixed frame and a moveable frame. A nest for accepting a plurality of semiconductor wafers is rotatably connected to the moveable frame. The nest rotates between a wafer-horizontal orientation and a wafer-vertical orientation as it is driven with the movable frame by a motor that is coupled to the linear way. A lever connected to the nest provides an offset from true vertical for the nest when the nest is in the wafer-vertical orientation.

  • Semiconductor processing apparatus having lift and tilt mechanism
    Patent number: 6645355
    Abstract: A lift/tilt assembly for use in a semiconductor wafer processing device is set forth. The lift/tilt assembly includes a linear guide comprising a fixed frame and a moveable frame. A nest for accepting a plurality of semiconductor wafers is rotatably connected to the moveable frame. The nest rotates between a wafer-horizontal orientation and a wafer-vertical orientation as it is driven with the movable frame by a motor that is coupled to the linear way. A lever connected to the nest provides an offset from true vertical for the nest when the nest is in the wafer-vertical orientation.
