摘要:
The present invention relates to nanoporous dielectric films and to a process for their manufacture. A substrate having a plurality of raised lines on its surface is provided with a relatively high porosity, low dielectric constant, silicon containing polymer composition positioned between the raised lines and a relatively low porosity, high dielectric constant, silicon containing composition positioned on the lines.

The invention addresses the use of a composite carbon dioxide scavenging filler which has been dispersed uniformly into a polymeric matrix. The resultant layer can then be coated or laminated onto a paper, paperboard, foil, or other substrates. It can also be made into a cast or blown film. The carbon dioxide scavenging structure thus created desirably contains a polymeric matrix binder as the filler dispersion medium, one or more particular carbon dioxide scavenging fillers, one or more moisture producing/retaining agents or moisture retaining agents, and, optionally, one or more polymeric or surfactant dispersion/wetting agents aiding the wetting and the uniform dispersion of the fillers in the matrix. This allows products contained in a package, such as roasted coffee, or produce, to maintain freshness and counteract pressure buildup in a package which results in bulging, rupture, loss of freshness, poor shelf appearance, and increased anaerobic bacterial activity.

A resin-impregnated endless belt for a long nip press of the shoe type has a base structure impregnated by a polymeric resin material which renders the belt impermeable to fluids, such as oil, water and air. The polymeric resin material forms layers on the inner and outer sides of the base structure. The inner layer is smooth, but the outer layer has primary grooves for the temporary storage of water pressed from a paper web. The primary grooves are separated by land areas which have secondary grooves extending thereacross to relieve stresses which give rise to flex fatigue and stress cracking.

An aesthetically enhanced building board is disclosed which is obtained by applying an effective shade coating to concavities of a building board having linear, curved, continuous or discontinuous concavities or any other concavities. In accordance with a cross-sectional geometry in crosswise direction of a groove 5 formed in a surface of a building board (A), level (hs), position (m), and jetting angle (&agr;) are controlled, thereby a coating is applied in such a manner that color of the coating is deepest in a bottom of the groove 5 and, in sides, it becomes lighter from the bottom to the surface.

A curved, transparent laminated glazing is made of at least two fixed panes and of a multilayer laminate placed between them. The laminate includes at least one support film provided with a thin layer and with external adhesive layers, as well as with a marginal strip of an opaque material for delimiting the viewing area of the laminated glazing on at least one side. The support film, which extends over the viewing area, is cut to size according to the invention in such a way that its cut edge is still just covered by the marginal strip at least in a direction of viewing in transmission.

A metal foil includes at least two intersecting structures, which are spaced from an imaginary reference surface and which define an intersection region. The at least two intersecting structures partially superpose one another in the intersection region and are formed with at least one through opening in the intersection region. A honeycomb body includes at least one flat construction formed with channels, which define a flow direction for a fluid to flow through the channels. The at least one flat construction has at least two intersecting structures, which are spaced from an imaginary reference surface and which define an intersection region. The at least two intersecting structures partially superpose one another in the intersection region and have at least one through opening in the intersection region.

After laminating together the first sheets crepe-processed at a high crepe ratio and the second sheet crepe-processed at a crepe ratio lower than that of the first sheet or not crepe-processed, the sheets are bonded together at bonding parts at a given pitch in rows. When the resulting bonded sheets are impregnated with a liquid, expansions are generated between the rows of bonding parts due to the difference in ratios of the elongation of the two sheets. The expansions take on the shape of large wrinkle according to the pitch of the bonding parts. At the production process of the sheet, the sheet is crepe-processed containing water at a preset ratio, whereby small wrinkles as residual crepe wrinkles are formed on the sheet surface. The large wrinkles and the small wrinkles can enhance the wiping effect.

Composites of paper and bioriented polyester plastic film are made by passing a web of paperboard and a web of plastic film, with a layer of extruded molten polymer impregnating and bonding agent between the webs, through a nip. The process involves controlling one or more of the speed of the webs, the temperature of the molten polymer, the pressure or spacing of the rolls at the nip, and the rate of extrusion, relative to the porosity and surface characteristics of the paper web such that a portion of the molten polymer impregnates partially into and becomes part of the paper web and a substantial portion lies outwardly of the surface of the paper web and solidifies to form a new surface to which the film is bonded and which it is supported clear of the paper surface. The molten polymer may be polyethylene or an ethylene acrylic acid copolymer. These composites are useful in forming corrugated structures which may be used for baking in convection ovens.
