The floor covering includes multiple layers including a non-woven base layer, a VAE precoat applied to the non-woven woven base layer and overlaid by a first PVC layer. A fiberglass mat is applied over the first PVC layer and a second PVC layer is applied over the mat. A woven PVC layer is laminated by heat and pressure to the underlying second PVC layer. The woven PVC layer comprises monofilament or multifilament cores, preferably but not limited to, polyester filaments overlaid by a PVC coating.

A curable underfill encapsulant composition that is applied directly onto semiconductor wafers before the wafers are diced into individual chips. The composition comprises a thermally curable epoxy resin, a solvent, an imidazole-anhydride curing agent, fluxing agents, and optionally, wetting agents. Various other additives, such as defoaming agents, adhesion promoters, flow additives and rheology modifiers may also be added as desired. The underfill encapsulant is B-stageable to provide a coating on the wafer that is smooth, non-tacky and will allow the wafer to be cleanly diced into individual chips. A method for producing an electronic package containing the B-stageable material may also utilize an unfilled liquid curable fluxing material on the substrate to which the chip is to be attached.

A method and apparatus for preparing a tire surface for installation of a transponder apparatus of the type comprising a transponder housing and an antenna, includes the steps: identifying a tire target surface having a footprint configured to receive the transponder apparatus thereagainst; positioning the tire target surface in an accessible relationship to cleaning apparatus; and actuating the cleaning apparatus to substantially eliminate undesired surface agents from the tire target surface. Relative movement between the cleaning apparatus and the tire target surface may be initiated to create the desired target surface shape, such as an annular configuration, and to facilitate a substantial purging of undesired surface agents from substantially all of the target surface.

To produce a capacitor with a target static capacitance, an apparatus for producing a laminated ceramic capacitor is adapted to measure the thickness of a green sheet and the area of an internal electrode by an in-line system and with high accuracy, and to laminate a calculated number of the green sheets based on the measured values. The apparatus includes a sheet-supplying unit, a sheet-thickness measuring unit, a laminating unit, and a discharging unit.

A thermoplastic binder applied in the vicinity of the roots of a pile surface structure, typically before stitching, is raised above its melting point but below the critical exposure temperature that can adversely affect the properties of the material forming the pile elements. While at this elevated temperature the pile surface structure is mechanically flexed, as by repeatedly bending the backing with the pile loops thereon into and out of its plane. This flexing action assists the molten (but not freely flowing) binder to propagate into the roots of the pile elements and into the interstices between the fibers forming the same.

The present invention is a laminate comprising at least one layer of an polyallylamine-based coating that is and in direct contact with at least one other polymeric layer.
摘要:
A method of producing an antireflection structure for use on a display or a window surface or both in an electronic device, such as a mobile phone. The display can be an LCD with a top polarizer and a bottom polarizer. The antireflection structure is imparted on the top polarizer by a roller embossing process. In particular, the embossing is carried out in the same manufacturing process when the polarizer is produced. The antireflection structure has a plurality of sub-wavelength periodic grooves. The antireflection structure on the window surface can be imparted using an embossing process or an injection molding process.
