Patents by Inventor James C. Zesch

James C. Zesch 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: 8836739
    Abstract: A printer has a print head arranged to jet molten ink onto a surface, a transfix surface arranged to provide the surface for the print head, the transfix surface having a core and an outer shell of a predetermined grade of aluminum arranged on the core, the outer shell forming the surface for the print head. The printer also has a transport subsystem to transport a print substrate past the transfix surface such that the molten ink transfers from the transfix surface to the print substrate.
    Type: Grant
    Filed: September 7, 2012
    Date of Patent: September 16, 2014
    Assignee: Palo Alto Research Center Incorporated

  • Patent number: 7517043
    Abstract: Various fluidic techniques can employ ducting structures, such as microstructures, that extend between other components, such as plate-like structures. A ducting structure can, for example, include an inlet opening toward or near one plate-like structure, an outlet opening toward or near another plate-like structure, and a duct in which fluid flows after being received through the inlet opening and before being provided through the outlet opening. In some implementations, a ducting structure is photo-defined, such as by exposing a photoimageable structure and then removing either exposed or unexposed regions. In some implementations, a ducting structure is a freestanding polymer microstructure. In some implementations, ducting structures are microstructures that extend approximately the same length between first and second plate-like structures, and have a ratio of length to maximum cavity diameter of approximately two or more.

  • Patent number: 6200491
    Abstract: An acoustic lens array fabrication process includes the formation of a microlens array mold stamper through the melting of a photoresist resin deposited on formed pedestals of a substrate. Heating of the resin causes formation of semi-spherical photoresist mounds. A further processing step, such as reactive ion etching, is used to transfer the geometry of the photoresist mounds to the substrate material, thereby forming a microlens mold stamper with convex mounds. The microlens mold stamper is then pressed into an upper surface of a acoustic ink print head substrate heated to a predetermined temperature, allowing the convex mounds to form concave impressions in the acoustic ink print head substrate, thereby forming the microlens array.

  • Patent number: 3938881
    Abstract: An acousto-optic modulation device is provided which is comprised of an interaction material of an injection moulded plastic integrally combined with a transducer which is bonded automatically to the interaction material during the injection process. A beam of light is projected through the interaction material, the light being diffracted by an acoustic field established by the transducer.
