An RF power supply is connected to one of the first and second electrodes and configured to apply an RF power for plasma generation.
Abstract:
A printing apparatus includes a magnetic rotatable roller with a smooth even outer surface for aligning magnetic flakes in a carrier, such as an ink vehicle or a paint vehicle to create optically variable images in a high-speed, linear printing operation. Images can provide security features on high-value documents, such as bank notes. Magnetic flakes in the ink are aligned using magnetic portions of the roller, that can be formed by permanent magnets embedded in a non-magnetic roller body, or selectively magnetized portions of a flexible magnetic cover of the roller. In some embodiments, the roller is assembled for a plurality of interchangeable sections, which can include spinning magnets. Selected orientation of the magnetic pigment flakes can achieve a variety of illusive optical effects that are useful for decorative or security applications.
Abstract:
A method of manufacturing a b-stage resin impregnated décor paper that is suitable for inclusion in a decorative or industrial laminate, includes impregnating a décor print base paper with a resin carried by a solvent, which resin includes one or more of melamine formaldehyde, urea formaldehyde, and phenol formaldehyde or any combination of these. Thereafter the resin impregnated paper is irradiated with near infra-red (NIR) radiation selected to partially remove solvent by evaporation of the solvent, whereby to produce a partially dried and partially cured printable b-stage resin impregnated paper. The partially dried and partially cured printable b-stage resin impregnated paper is then printed to obtain a décor paper suitable for subsequent final curing in the formation of a decorative or industrial laminate. Apparatus is also disclosed, as is a method that entails impregnating a paper with an aqueous urea solution and irradiating the wet impregnated paper with near infra-red (NIR) radiation.
Abstract:
A spray coating system is provided. The spray coating system includes a spin support for supporting and spinning the substrate; a sprayer for applying a material to an upper surface of the substrate; a cup surrounding a lateral and lower region of the spin support, wherein an opening is located in an upper central region of the cup; an air supply mechanism for supplying air flows to a back surface of the substrate to prevent the material from adhering thereto, and an exhaust zone disposed below a slanted surface of the cup for exhausting the air flow and material.
Abstract:
A system and method for photo-grafting a coating polymer onto the surface of a medical device are provided. The system comprises a plurality of stations including a novel grafting station. The system and method of the invention are both time- and resource-efficient. The system includes several stations, each station including a dipping tank. The system allows for the automated, semi-automated, or manual dipping of medical devices into the dipping tanks in a specified order, as desired, wherein at least one of the stations is a grafting station for photo-grafting the coating polymer onto the surface of the medical device. The system is modular, which allows for modification of the process as required, depending on the needs of the user. The system may comprise stations for incorporating an antimicrobial agent into the coating, and/or for rendering the coating lubricious.
Abstract:
The present invention provides a coating apparatus capable of coating an object with a highly viscous material at high precision in the applied amount of the highly viscous material and uniformity in the shape of the applied highly viscous material layer. The present invention relates to a coating apparatus capable of coating an object such as the metal sheet of an automobile body with a highly viscous material such as a coat type metal sheet-reinforcing material, at high precision in the applied amount (or the thickness of the applied material layer) and uniformity in the shape of the applied viscous material layer, so as to ensure the reliable reinforcing effect of the reinforcing material. The present invention also pertains to a coating method using the same apparatus, and a coated article provided by using the same apparatus.
Abstract:
A plasma silanization system includes a processing vessel having a metal shelf and a non-metallic component support configured to elevate a component above the metal shelf to prevent excess silane deposition. A method of applying silane to a component in a plasma processing apparatus having a metal shelf includes placing a non-metallic component support on the metal shelf and placing a component on the non-metallic component support to prevent excess silane deposition.
Abstract:
According to the invention, there is provided an image recording composition comprising a curable material capable of immobilizing a colorant material in a received ink and curable by an external stimulus.
Abstract:
A lithographic method includes providing particles in dry form on a substrate, or on material provided on the substrate, irradiating one or more of the particles with a dose of radiation, the dose of radiation being sufficient to ensure that at least one particle of the one or more particles is bonded to the substrate, or to the material provided on the substrate, and removing particles from the substrate, or from material provided on the substrate, that have not been bonded to the substrate, or to the material provided on the substrate.
Abstract:
Light reactive deposition uses an intense light beam to form particles that are directly coated onto a substrate surface. In some embodiments, a coating apparatus comprising a noncircular reactant inlet, optical elements forming a light path, a first substrate, and a motor connected to the apparatus. The reactant inlet defines a reactant stream path. The light path intersects the reactant stream path at a reaction zone with a product stream path continuing from the reaction zone. The substrate intersects the product stream path. Also, operation of the motor moves the first substrate relative to the product stream. Various broad methods are described for using light driven chemical reactions to produce efficiently highly uniform coatings.
