  • Publication number: 20050261795
    Abstract: Dental restorations can be made by acquiring a three-dimensional digitized image of a dental restoration site. A ceramic blank from which volatile organic binders have been removed, is then machined according to the three-dimensional digitized image to form a “brown” ceramic restoration. This material is then sintered using microwave energy to provide a high density ceramic dental restoration corresponding to the dental restoration site. This method can be carried out within a few hours thereby saving the patient several dental visits and enabling the dentist to better serve the patient directly in the office.

  • Publication number: 20050056968
    Abstract: A method of forming a homogeneous mixture of powders of organic materials, which includes, at least one dopant component and one host component to form a pellet for thermal physical vapor deposition producing an organic layer on a substrate for use in an organic light-emitting device. The method includes, combining organic materials while an emulsifying liquid is provided, after which, the emulsified organic materials are mixed to form a homogeneous mixture of organic material. The homogenous mixture of organic materials is then heated in a container until the emulsifying liquid is evaporated and a solidified homogenous mixture of organic materials remains. The solidified homogeneous mixture of organic materials are removed from the container, pulverized into a homogeneous mixture of organic powder, and compacted to form pellets suitable for thermal physical vaporization to produce an organic layer on a substrate for use in an organic light-emitting device.

  • Publication number: 20050056960
    Abstract: A method for forming homogeneous mixtures of powders of organic materials, which include, at least one dopant component and one host component, to provide a homogenous mixture for use in thermal physical vapor deposition to produce an organic layer on a substrate for use in an organic light-emitting device. The method includes, combining organic materials having at least one dopant component and one host component to form a mixture of organic materials and placing the mixture of organic materials in a container and sealing the container. The method further includes, heating and mixing the organic materials until they are melted, to form a homogeneous mixture of organic materials. Solidifying the homogeneous mixture of organic materials and removing the solidified homogeneous mixture of organic materials from the container.

  • Publication number: 20050056969
    Abstract: A method for forming homogeneous mixtures of powders of organic materials, which include, at least one dopant component and one host component, to provide a homogeneous mixture for use in thermal physical vapor deposition to produce an organic layer on a substrate for use in an organic light-emitting device. The method includes combining organic materials, such organic materials including at least one dopant component and one host component and providing a solvent with the organic materials to form a suspension of organic powders in the solvent. Subsequently mixing the suspension to form a solution of the organic materials in the solvent and finally evaporating the solvent from the solution leaving a homogeneous mixture of organic powder.

  • Publication number: 20050056958
    Abstract: Powdered organic material s are mixed to form a homogeneous mixture, which includes, at least one dopant component and one host component, to form a pellet for use in thermal physical vapor deposition to produce an organic layer on a substrate for use in an organic light-emitting device. The method of mixing includes, combining organic materials in a powder form and placing the powder organic materials in a container, heating the container in a range of temperatures from 40 to 100° C. for 30 to 100 minutes while purging the atmosphere in the container to a reduced pressure in a range from 10?1 to 10?3 Torr to remove moisture. Filling the container with an inert atmosphere, mixing the powder organic materials in the inert atmosphere to form a homogeneous mixture of powder organic materials, and compacting the homogenous mixture of powder organic materials to form a pellet.

  • Publication number: 20050016461
    Abstract: A thermal physical vapor deposition source for vaporizing compacted pellets of organic materials onto a surface of a substrate in forming a display, including a housing defining a plurality of spaced passages each for receiving compacted pellets, a cover plate over the housing, with a first plurality of openings corresponding to the spaced passages of the housing and an electrical heater structure disposed over the cover plate. The thermal physical vapor deposition source further including an aperture plate, disposed over the electrical heater structure, an electrically insulating spacer member located between the electrical heater structure and an aperture plate, and circuitry for applying current to the electrical heater structure to produce heat sufficient to vaporize the pellets and permit vapor efflux of materials to pass through the cover plate, the heater structure, the electrically insulating spacer member and the aperture plate, onto the substrate.
