Publication number: 20150000622Abstract: Downstream expansion cylinders are associated with a combustion cylinder such that an overall surface area and displacement volume of the expansion cylinder is sufficient to lower the temperature of fluids associated with the combined engine to such an extent that a radiator can be eliminated in an associated vehicle, or other system. In a separate feature, a catalytic material is placed on surfaces which will “see” the hot exhaust gases such that catalytic conversion of impurities in the gases can be achieved within the engine itself. In yet another feature, water is recovered from a system having both a water injection expansion cylinder, and a combustion cylinder, and the recovered water is re-used for the expansion. In yet another feature, gearing is provided between the expansion cylinder and a combustion cylinder such that the output of the combined engine is optimized, and the two cylinders do not drive the crankshafts in a one-to-one fashion.Type: ApplicationFiled: September 16, 2014Publication date: January 1, 2015Inventor: Ronald D.

Patent number: 8318066Abstract: The present invention is directed to methods for patterning a substrate by imprint lithography. Imprint lithography is a process in which a liquid is dispensed onto a substrate. A template is brought into contact with the liquid and the liquid is cured. The cured liquid includes an imprint of any patterns formed in the template. In one embodiment, the imprint process is designed to imprint only a portion of the substrate. The remainder of the substrate is imprinted by moving the template to a different portion of the template and repeating the imprint lithography process.Type: GrantFiled: May 16, 2011Date of Patent: November 27, 2012Assignee: Molecular Imprints, Inc.Inventors: Sidlgata V.

Patent number: 7943081Abstract: Methods of forming continuous layers on regions of a substrate are described. Generally, an imprint lithography template may contact liquid positioned on the substrate. The liquid may be cured forming a masking layer, and the imprint lithography template separated from the masking layer. Prior to separation, pressurized gas and/or vacuum may be applied between the template and the substrate. Additionally, during separation, pressurized gas and/or vacuum may be applied between the template and the substrate.Type: GrantFiled: April 19, 2010Date of Patent: May 17, 2011Assignee: Molecular Imprints, Inc.Inventors: Sidlgata V.

Publication number: 20100278955Abstract: Imprint lithography templates for patterning substrates are described. The templates include a section having a mold, a first pattern of alignment forming areas and template alignment marks. The additional sections are generally devoid of a mold. One or more of the additional sections may include a second pattern of alignment forming areas and template alignment marks. The second pattern may correspond to the first pattern.Type: ApplicationFiled: July 13, 2010Publication date: November 4, 2010Applicant: MOLECULAR IMPRINTS, INC.Inventor: Ronald D. Voisin

Patent number: 7785526Abstract: An improved lithographic alignment method, system, and template. The method includes creating, within a lithographic subfield, subsequent-layer features which are intentionally offset from their respective previous-layer features, where the intentional offset may vary in magnitude and direction from one subfield to the next. The system includes an imprint lithographic machine and first and second lithography templates where the templates are adapted to enable the machine to form first and second features, respectively, and where a second feature is configured to be deliberately offset from a corresponding first feature. The template set includes at least two templates, one having features which are deliberately offset from corresponding features of another template. Also, a method of manufacturing such a template set.Type: GrantFiled: July 20, 2004Date of Patent: August 31, 2010Assignee: Molecular Imprints, Inc.Inventor: Ronald D. Voisin

Patent number: 7699598Abstract: The present invention includes a conforming template for patterning liquids disposed on substrates. The template includes a body having opposed first and second surfaces. The first surface includes a plurality of recessed regions with a patterning region being disposed between adjacent recessed regions. Specifically, the recessed regions define flexure regions about which each patterning region may move independent of the remaining patterning regions of the template. In one embodiment the template is mounted to a fluid chamber having an inlet and a throughway. The template is connected to the throughway and the inlet is connected to a fluid source to facilitate deformation of the template to conform to a profile of a surface adjacent thereto.Type: GrantFiled: January 31, 2007Date of Patent: April 20, 2010Assignee: Molecular Imprints, Inc.Inventors: Sidlgata V.

Publication number: 20090214686Abstract: The present invention is directed to a method forming conductive templates that includes providing a substrate; forming a mesa on the substrate; and forming a plurality of recessions and projections on the mesa with a nadir of the recessions comprising electrically conductive material and the projections comprising electrically insulative material. It is desired that the mesa be substantially transparent to a predetermined wavelength of radiation, for example ultraviolet radiation. As a result, it is desired to form the electrically conductive material from a material that allows ultraviolet radiation to propagate therethrough. In the present invention indium tin oxide is a suitable material from which to form the electrical conductive material.Type: ApplicationFiled: May 4, 2009Publication date: August 27, 2009Applicant: MOLECULAR IMPRINTS, INC.Inventors: Sidlgata V.

Patent number: 7547398Abstract: A process that enables coplanarization of the structures that have been created in multiple independent etch steps. The various etches are performed independently by selectively exposing only certain patterns to particular etching conditions. After these structures have been created, it is possible that the various structures will exist at different planes/elevations relative to the template surface. The elevations of the various structures may be adjusted independently by selectively exposing “higher” structures to an anisotropic etch that reduces the overall elevation of the structures, while preserving the structural topography.Type: GrantFiled: March 29, 2007Date of Patent: June 16, 2009Assignee: Molecular Imprints, Inc.Inventors: Gerard M. Schmid, Nicholas A Stacey, Douglas J. Resnick, Ronald D. Voisin, Lawrence J. Myron
