Abstract:
A soft alumite is produced by forming an oxide film on the surface of an aluminum substrate. Printing is performed on a porous layer formed on the surface of the soft alumite while heating the soft alumite. Alternatively, printing is performed with a dye-based ink on a porous layer formed on the surface of the soft alumite.
Abstract:
Polishing pads used in the manufacturing of microelectronic devices, and apparatuses and methods for making and using such polishing pads. In one aspect of the invention, a polishing pad for planarizing microelectronic-device substrate assemblies has a backing member including a first surface and a second surface, a plurality of pattern elements distributed over the first surface of the backing member, and a hard cover layer over the pattern elements. The pattern elements define a plurality of contour surfaces projecting away from the first surface of the backing member. The cover layer at least substantially conforms to the contour surfaces of the pattern elements to form a plurality of hard nodules projecting away from the first surface of the backing member. The hard nodules define abrasive elements to contact and abrade material from a microelectronic-device substrate assembly. As such, the cover layer defines at least a portion of a planarizing surface of the polishing pad.
Abstract:
Provided is a ceramic coated product and a coating for it, making it possible to improve corrosion resistance, wear resistance and the like of a material to be treated, and heighten aesthetically commercial value by a thin film forming or producing method using low-priced equipment. An ejection powder and a reactive ejecting gas are ejected onto a surface of a material to be treated comprising a metal product, a ceramic, or a mixture thereof. The ejection powder is heated on the surface of the material to be treated and then is reacted with the reactive ejecting gas. The resultant product is activation-adsorbed onto the surface of the material to be treated and caused to diffuse and penetrate thereinto. Thus, a layer made of a nitride or other compounds is formed.

Liquid dispersion A containing a thermosetting resin and a solid lubricant is applied to the inner surface of half bearing 1 by pad printing and then cured by heating to form lubricating film layer 4 of the inner surface of half bearing 1, where liquid dispersion A is pressed onto the inner surface of half bearing 1 by pad 7, whereby the density is made higher to increase the bond strength and improve the wear resistance and the cavitation resistance.
Abstract:
The present invention provides a material for distributing liquid and a method for making such a material. The material includes a substrate permeable to a liquid and a chemical treatment applied to at least a portion of the substrate. The substrate further includes a leakage prevention means of at least one area of an increased concentration of the chemical treatment such that the chemical treatment is non-uniform along a planar dimension of the substrate and creates an area of preferential flow through the substrate. The chemical treatment useful for application to the substrate preferably induces wetting of the substrate by a liquid. The material for distributing liquid has best utility as a component of an absorbent article, e.g. a liner of a diaper. In a preferred embodiment, the substrate is attached to an absorbent layer such that the absorbent layer receives and retains the liquid when the liquid flows from a first planar dimension to a second planar dimension. Preferably, the absorbent layer is attached to an inner face of the substrate in face-to-face juxtaposition. The leakage prevention means is generally positioned in the absorbent article to prevent leakage out of the periphery of said absorbent article and the periphery is generally less wettable than the leakage prevention means.

A plurality of sheets thus decorated can be assembled with or without distance pieces and set in a frame, to form a decorative panel.
Abstract:
A method is provided for making mirrors having enhanced reflective layer resistance to corrosion. The reflective layer of the mirror, typically silver, is contacted, preferably simultaneously, with a first solution containing a specific cation and a second solution containing a specific anion, or alkaline material which forms hydroxyl ions, the specific cation and specific anion or hydroxyl ion reacting to form a water insoluble precipitate on the silver surface. The mirror may then be painted to provide additional corrosion resistance to the mirror. The method eliminates the need for a copper layer on the silver surface and the method may be incorporated into existing mirror production lines as a replacement for the copper layering step. Also provided are an apparatus for making the mirrors and the mirrors made using the method and apparatus of the invention. A preferred cation containing solution contains tin (e.g., SnCl2) and a preferred anion containing solution contains hydroxyl ions (e.g., NaOH).
Abstract:
The present invention relates to a processing means 1 for masking regions of a vehicle during the painting operation. The invention also relates to a method of manufacturing and recycling processing means 1 of this kind, as well as to a method of masking regions of a vehicle during the painting operation with such a processing means 1. It is the objective of the present invention to make available a recyclable processing means 1 of the kind cited above, which under the conditions of a painting operation exhibits a shape, stability and firmness such that its use provides advantages regarding economy and quality as well as ecological considerations. This objective is achieved by a processing means 1 for masking regions of a vehicle that consists of a plastic material and can be placed on a cathodal dip-priming coat covering the flange 2 around openings in a vehicle body or vehicle module, so as to produce a form-fitting seal. After removal of the processing means 1 from the vehicle-body flange 2, the result is a good adherence and ageing-resistant bonding quality between an adhesive 4 and a window pane 3. The processing means in its painted state can be simply and ecologically recycled and re-used.
Abstract:
The invention relates to a method for utilizing one or more B-stageable or pre-formed underfill encapsulant compositions in the application of electronic components, most commonly chip scale packages (CSP's) to substrates. One such composition comprises a thermoplastic resin system comprising a phenoxy resin, an expandable polymer sphere or thermosetting composition, optionally an epoxy resin such as higher molecular weight epoxy resin, a solvent, an imidazole-anhydride catalyst or comparable latent catalyst, and optionally, fluxing agents and/or wetting agents. The underfill encapsulant may be B-stageable to provide a coating on the substrate or component that is smooth and non-tacky. In an alternative embodiment, the underfill encapsulant is a pre-formed film. In both embodiments the expandable filler material expands upon the application of higher temperatures to form a closed-cell foam structure in the desired portion of the assembly. The method of applying the underfill application of the underfill to a component or substrate, attachment of the component and substrate, and heating of the assembly to a temperature sufficient to cause the expandable thermoplastic or thermosetting composition to foam. A second pre-applied underfill composition containing an epoxy resin, an anhydride curing agent, and catalyst may also be applied, either separately or in conjunction with the foamable underfill. The second composition acts as a pressure sensitive adhesive and may be applied selectively to parts of the CSP, for example to the solder bumps. The pressure sensitive adhesive property of the composition provides sufficient tack in order to hold the electronic assembly together during the assembly process.
