Gas Or Vapor Deposition Of Article Forming Material Onto Mold Surface Patents (Class 264/81)
  • Patent number: 12076789
    Abstract: The present disclosure generally relates to additive manufacturing systems and methods on a large-scale format. One aspect involves a build unit that can be moved around in three dimensions by a positioning system, building separate portions of a large object. The build unit has an energy directing device that directs, e.g., laser or e-beam irradiation onto a powder layer. In the case of laser irradiation, the build volume may have a gasflow device that provides laminar gas flow to a laminar flow zone above the layer of powder. This allows for efficient removal of the smoke, condensates, and other impurities produced by irradiating the powder (the “gas plume”) without excessively disturbing the powder layer. The build unit may also have a recoater that allows it to selectively deposit particular quantities of powder in specific locations over a work surface to build large, high quality, high precision objects.

When porous silica is synthesized by hydrolyzing an alkoxysilane in a solvent-free system, it is possible to synthesize porous silica having a fine pore diameter. Use of this porous silica as a template facilitates formation of particles (e.g., W, Cu, Cr, Mn, Fe, Co, or Ni or an oxide of any of these metals) that show peculiar properties not observed in the bulk material.

  • Publication number: 20120326702
    Abstract: The main object of the invention is to provide an electromagnetic wave resonator making use of surface waves: an electromagnetic wave resonator structure capable of being achieved with existing technologies yet without much difficulty and applying voltage to a positive dielectric area, thereby overcoming a variety of problems arising from the fact that only thermal excitation is available. The contact structure of negative dielectric/positive dielectric/negative dielectric necessary for this type of electromagnetic wave resonator is provided on the surface of the negative dielectric material 1 just as the coaxial structure of the positive dielectric thin film 3 extending in the Y-axis direction and the negative dielectric material 2 received therein is cut in the axial direction.

  • Publication number: 20120312693
    Abstract: Certain example embodiments of this invention relate to the use of graphene as a transparent conductive coating (TCC). In certain example embodiments, graphene thin films grown on large areas hetero-epitaxially, e.g., on a catalyst thin film, from a hydrocarbon gas (such as, for example, C2H2, CH4, or the like). The graphene thin films of certain example embodiments may be doped or undoped. In certain example embodiments, graphene thin films, once formed, may be lifted off of their carrier substrates and transferred to receiving substrates, e.g., for inclusion in an intermediate or final product. Graphene grown, lifted, and transferred in this way may exhibit low sheet resistances (e.g., less than 150 ohms/square and lower when doped) and high transmission values (e.g., at least in the visible and infrared spectra).

  • Publication number: 20120304762
    Abstract: A method for producing a pyrolytic boron nitride (PBN) article comprises introducing a nitrogen containing gas and a boron containing gas into a heated reactor furnace under temperature and pressure conditions sufficient to form a PBN deposit and pulsing the flow of the reactant gases between an on and an off state. The method provides a multi-layered PBN article that exhibits a relatively weak bonding interface between adjacent PBN layers to allow for the layers to be peeled away from one another in a controlled manner.

  • Publication number: 20120225296
    Abstract: A method of producing uniform multilayer graphene by chemical vapor deposition (CVD) is provided. The method is limited in size only by CVD reaction chamber size and is scalable to produce multilayer graphene films on a wafer scale that have the same number of layers of graphene throughout substantially the entire film. Uniform bilayer graphene may be produced using a method that does not require assembly of independently produced single layer graphene. The method includes a CVD process wherein a reaction gas is flowed in the chamber at a relatively low pressure compared to conventional processes and the temperature in the reaction chamber is thereafter decreased relatively slowly compared to conventional processes. One application for uniform multilayer graphene is transparent conductors. In processes that require multiple transfers of single layer graphene to achieve multilayer graphene structures, the disclosed method can reduce the number of process steps by at least half.

    Abstract: The invention relates to a method of fabricating a micromechanical part (11, 31, 41) made of a single piece material. According to the invention, the method includes the following steps: a) forming a substrate (1, 21) which includes the negative cavity (3, 23) for said micromechanical part to be fabricated; b) forming a sacrificial layer (5, 25) on one portion of the substrate (1, 21); c) depositing particles (6, 26) on the substrate (1, 21) intended to form a germination layer; d) removing the sacrificial layer (5, 25) so as to selectively leave one portion of the substrate (1, 21) free of any particles (6, 26); e) depositing a layer of material (7, 27) by chemical vapour phase deposition so that the material is exclusively deposited where the particles (6, 26) remain; f) removing the substrate (1, 21) to release the micromechanical part (11, 31, 41) formed in said negative cavity.

  • Publication number: 20120153527
    Abstract: A process for manufacturing stand-alone thin films is provided. The process includes providing a substrate, depositing a carbon-containing sacrificial layer onto the substrate and the depositing a thin film onto the carbon-containing sacrificial layer. Thereafter, the substrate, carbon-containing sacrificial layer and thin film structure are exposed to oxygen at an elevated temperature. The oxygen reacts with the carbon-containing sacrificial layer to produce carbon dioxide and remove carbon from the sacrificial layer, thereby generally burning away the sacrificial layer and affording for an intact stand-alone thin film to separate from the substrate.
