  • Period reconfiguration and closed loop calibration of an interference lithography patterning system and method of operation
    Patent number: 6556280
    Abstract: A lithographic tool system for generating an interferometric pattern of light using a plurality of exposure beams includes a processor coupled to a positioning device. The processor receives a selected period for the interferometric pattern of light, and generates an angular control signal and a translational control signal in response to the selected period. The positioning device translates an exposure beam in response to the translational control signal, and rotates the exposure beam in response to the angular control signal.

  • Interference lithography using holey fibers
    Patent number: 6522433
    Abstract: A method and apparatus for interference lithography utilize a fiber having a cladding region with axially formed holes surrounding a core region. The fiber emits an optical signal to perform interference lithography. A number of alternative variations in the size and arrangement of axially formed holes produces fibers having characteristics particularly adapted for receiving, communicating, and emitting optical signals for interference lithography.

  • Polarization vector alignment for interference lithography patterning
    Publication number: 20020149757
    Abstract: A polarization vector alignment technique for interference lithography generates a control signal indicating a difference in orientation between a polarization state of an emitted optical signal and a desired linear polarization vector. The technique adjusts the linear polarization vector to enhance the quality of the pattern produced for interference lithography.

  • Book binding apparatus and method
    Patent number: 5261769
    Abstract: An apparatus and method for applying a soft cover to book block is disclosed. A book block conveyor moves the book block to a cover applying station. A first adhesive applicator applies adhesive to the spine of the book block. A soft cover conveyor transports the soft cover to the covering station in a timed relationship to the book block. A crash feeder attaches crash to a first portion of the soft cover that covers a first side of the book block as the soft covers pass the crash feeder. The crash is attached to the soft cover so that the crash engages a spine portion of the cover that covers the spine of the book block but is not attached to the spine portion.
