Abstract:
There is provided a corrugated nonwoven web where at least 40 percent of the web surface area is made from fusible fibers. The corrugated web is bonded such that no gaps are present between the folds of the web. Such webs provide comparable compression resistance and resiliency to, and greater void volume than, webs having a conventional X-Y plane fiber alignment. There is further provided personal care products having the corrugated nonwoven web as a component where the web is placed in the product in the transverse direction.
Abstract:
A textile laminate for covering diverse substrates includes a backing layer to be placed adjacent to the substrate, a substantially non-shrinkable fibrous layer coextensive with the backing layer and an adhesive component to bind the fibrous layer to the backing layer. The adhesive component is activated to adhere the fibrous and backing layers only at selected bonding points in a pattern bond. The backing layer is a material adapted to irreversibly shrink by at least about 25% such that after the backing layer shrinks, the fibrous layer separates from the backing layer at locations away from the bonding points and forms pile-like loops that protrude in a direction normal to the plane of the textile laminate.
Abstract:
A multifunctional member with a first active member (30), which is adapted to contract if exposed to a temperature above a first transition temperature range. A second active member (40), which is adapted to contract if exposed to a temperature above a second transition temperature range. A core member (20), which is adaptive for deformation. The first and second active members (30, 40) are attached on opposite or different sides of the core member (20). A heat source operatively connected to the first and second active members (30, 40) to expose them to transition temperatures. The first active member (30) contracts while above the first transition temperature range causing the second active member (40) to expand, wherein the second active member (40) is below the second transition temperature range. The second active member (40) contracts while above the second transition temperature range causing the first active member (30) to expand, wherein the first active member (30) is below the first transition temperature range.

A method of making an embossed optical sheet material includes: providing an optically anisotropic, uniaxially oriented polymer substrate having a first major surface and a second major surface; heating a patterned tool using radiant energy from a radiant energy source, wherein the pattern comprises a plurality of parallel raised microstructures having a longitudinal direction; pressing the tool against the first major surface of the polymer substrate such that the longitudinal direction of the raised microstructures is substantially parallel to the direction of orientation of the polymer substrate, to soften the first major surface of the polymer substrate and emboss groove-shaped microchannels into the polymer substrate; cooling the embossed polymer substrate; and separating the tool from the polymer substrate; wherein the orientation of the polymer substrate is unchanged throughout the polymer substrate and first major surface.
Abstract:
Nonwoven substrates suitable for use as wet wipes are disclosed. The nonwoven substrates comprise at least one first region and at least one second region. The second region comprises reinforced protruding elements. In a preferred embodiment, the second region of the nonwoven substrate is reinforced by means of thermal bonding during the creation of the protruding elements of the second region. A liquid can be added to the nonwoven substrate prior to packaging or prior to use to make wet wipes. The reinforced second regions of the nonwoven substrates of the present invention make it possible to retain thickness of the wipe when wet without increasing the dry basis.
Abstract:
A method of manufacturing semiconductor devices with buried conductive lines is disclosed. The method uses an ion implantation process to form buried conductive lines under isolation regions such as shallow trench isolations. The buried conductive lines connect neighboring active regions and replace conventional contacts and lead lines connecting the active regions.
Abstract:
A bolt flange is provided with parallel grooves across its surface. One bolt flange surface has grooves that run in a vertical direction, while a second bolt flange surface has grooves that run in a horizontal direction, such that they are perpendicular to the grooves of the first bolt flange mating surface. The purpose of the grooves is to create a surface that consists of flexures. These flexures cause two effects to occur at the bolted interface. First, for a given clamping force, the resulting surface is greater because of the smaller contact area at the interface which in turn increases the friction force. Second, the flexures are sufficiently flexible enough to bend and not slide as the two interface surfaces move relative to each other. The flexure points may different configurations, i.e. squares, circles, triangles, or other geometric shapes. The grooving of the surfaces allows a designer of optical instruments to be capable of determining the stiffness of the resulting flexure as well as control the percentages of forces that are transferred across an interface through friction as compared with elastic bending. The flexured interface also allows the designer to invoke load path management design rules. In summary, load path management is a process by which a designer can control the effect of friction by not effecting the frictional mechanisms, but by changing the elastic stiffness that surrounds the frictional element. Placing grooves in the interface mating surfaces enables a designer to model the interface stiffness as a series of bending beams, which in turn allows the designer to explicitly model the percentage of force that acts through friction.
