Abstract:
A method for applying a protective coating to selected portions of a substrate is disclosed. The method includes applying a mask to or forming a mask on at least one portion of the substrate that is not to be covered with the protective coating. The mask may be selectively formed by applying a flowable material to the substrate. Alternatively, the mask may be formed from a preformed film. With the mask in place, the protective coating may be applied to the substrate and the mask. A portion of the protective coating that overlies the mask may be delineated from other portions of the protective coating; for example, by cutting, weakening or removing material from the protective coating at locations at or adjacent to the perimeter of the mask. The portion of the protective coating that overlies the mask, and the mask, may then be removed from the substrate.
Abstract:
An optical proximity sensor is provided that comprises an infrared light emitter an infrared light detector, a first molded optically transmissive infrared light pass component disposed over and covering the light emitter and a second molded optically transmissive infrared light pass component disposed over and covering the light detector. Located in-between the light emitter and the first molded optically transmissive infrared light pass component, and the light detector and the second molded optically transmissive infrared light pass component is a gap. Layers of infrared opaque, attenuating or blocking material are disposed on at least some of the external surfaces forming the gap to substantially attenuate or block the transmission of undesired direct, scattered or reflected light between the light emitter and the light detector, and thereby minimize optical crosstalk and interference between the light emitter and the light detector.
Abstract:
The present invention relates to highly ordered arrays of nanoholes in metallic films and to an improved method for producing the same. The method according to the invention for producing an highly ordered array of nanoholes in metallic films on a substrate comprises the following steps: a) providing microspheres comprising poly-N-isopropylamide (polyNIPAM), the microspheres being selected from pure poly-N-isopropyl-amide (polyNIPAM) hydrogel microspheres and polymeric or inorganic beads carrying poly-N-isopropylamide (polyNIPAM) hydrogel chains, b) coating an aqueous dispersion of said microspheres onto a substrate and drying the dispersion, which results in a non-close packed ordered array of the microspheres, c) generating a metallic film on the substrate, d) removing the microspheres from the surface of the substrate which results in an ordered array of nanoholes on the substrate, and e) optionally increasing the thickness of the metallic film by selective electroless plating.
Abstract:
A method for forming an electronic device having a multilayer structure, comprising: embossing a surface of a substrate so as to depress first and second regions of the substrate relative to at least a third region of the substrate; depositing conductive or semiconductive material from solution onto the first and second regions of the substrate so as to form a first electrode on the first region and a second electrode on the second region, wherein the electrodes are electrically insulated from each other by the third region.
Abstract:
A co-extruded plastic film comprises an outer layer formed of a high density polymer or co-polymer having a high surface energy, such as a medium molecular weight high density polyethylene that is corona treated or includes a relatively polar polymer, a core layer preferably formed of a polyolefin, which can include linear low density polyethylene or a foamed polymer preferably produced by an endothermic blowing agent, and an inner layer formed of a polymer having good cling properties that includes a filler of sufficiently large particle size and in a sufficiently large amount that vapors can escape laterally from under the film. This film allows vapors to disperse and can also be moisture absorbent and vapor permeable. The film also has the benefit that one surface has high paint adherence and the opposite surface clings to a substrate while having good lateral transmissivity of vapors.
Abstract:
A method for forming an electronic device in a multilayer structure comprising the steps of: defining a topographic profile in a laterally extending first layer; depositing at least one non-planarizing layer on top of the first layer such that the topographic profile of the surface of the or each non-planarizing layer conforms to that of the laterally extending first layer; and depositing a pattern of at least one additional layer onto the top-most non-planarizing layer, such that the lateral location of the additional layer is defined by the shape of the topographic profile of the non-planarizing layer, and whereby the additional layer is laterally aligned with the topographic profile in the first layer.
Abstract:
There is disclosed a method for permanently and decoratively enhancing a polyethylene surface of a preformed article. In this method, a decorative enhancement composition is created by blending particulate thermoplastic powder, a binder solid, and a colorant into a liquid carrier. The particulate thermoplastic powder bonds to the colorant, the binder solid promotes adhesion of the colored thermoplastic to the polyethylene surface until it can be bonded, and the liquid carrier facilitates the transfer of the colored thermoplastic to the polyethylene surface of the preformed article. The decorative enhancement composition is applied to the polyethylene surface. The deposited decorative enhancement composition and the interfacing polyethylene surface are heated sufficiently to incorporate the decorative enhancement composition into the polyethylene surface. The enhanced polyethylene surface is allowed to cure by removal of the application of heat. Upon curing, the decorative enhancement composition is permanently incorporated into the polyethylene surface enhancing the physical properties and the appearance of the preformed article. This invention also comprises a decorative enhancement composition for the permanent decorative enhancement of polyethylene surfaces of preformed articles consisting essentially of a dry weight ratio of 30 to 70 percent binder solid to 70 to 30 percent particulate thermoplastic powder combined with colorant, wherein colorant comprises 9 to 50 percent of the total dry weight of the binder, powder, and pigment, mixed with liquid carrier, wherein the liquid carrier comprises 20 to 90 weight percent of the overall decorative enhancement composition.
Abstract:
A method for isolating non-conductive oxide constituents of paint from the product support hook surfaces of an electrostatic painting conveyor, coats the hooks with a conductive coat of primer paint having from 10% to 80% finely divided conductive materials in a combustible base, and after using the product support hooks for spray painting product units until a non-conductive paint coating builds-up, removes the build-up and the primer coat in a burn-off oven, so as to provide conductive hook surfaces for repeating the process cycle.
Abstract:
A device for protecting a surface from paint spray in a paint spray booth having a plurality of flexible sheets. An adhesive is applied to at least a portion of one side of each sheet for both detachably securing the sheets together in a stack and also for detachably securing an end sheet in the stack to the surface to be protected. A tab is secured to each sheet which enables the removal of the sheet associated with the tab from the stack by peeling the sheet away using the tab. The sheets are preferably made of a transparent material.
