Multi-layer composite material, production and use thereof A multilayered composite material comprises as components: (A) a sheet material, (B) a material capable of absorbing water or aqueous fluids, (C) at least one bonding layer and (D) a polyurethane layer with capillaries passing through the entire thickness of the polyurethane layer,
wherein the polyurethane layer (D) comes into direct contact with sheet material (A) or absorption-capable material (B) in one or more places.

Devices with internal flexibility sipes, such as slits, provide improved flexibility, improved cushioning to absorb shock and/or shear forces, and improved stability of support. Siped devices can be used in any existing product that provides or utilizes cushioning and stability. These products include human and other footwear, both soles and uppers, as well as orthotics; athletic, occupational and medical equipment and apparel; padding or cushioning, such as for equipment or tool handles, as well as furniture; balls; tires; and any other structural or support elements in a mechanical, architectural, or any other product.

A roof product has a thermal heat storage layer, a vent layer with channels for transferring excess heat through a length of the roof product, and a flame retardant to suppress fire through the vent layer. These three materials form a unitary structure. The roof product may have a radiant layer, the thermal heat storage layer and the vent layer to form the unitary structure. The roof products are assembled in an abutting configuration on the roof of a building. The vent layer vents excess heat from an eave of the roof up to a ridge of the roof and out to atmosphere. The roof products manage thermal energy in the roof by storing thermal heat with the unitary roof product during a heating cycle; venting excess heat through the unitary product; and releasing the stored thermal heat from the unitary product into or out of the building during a cooling cycle.

A disposable wearable article includes an elastic film stretchable structure in which an elastic film is laminated between a first sheet layer and a second sheet layer. The first sheet layer and the second sheet layer are bonded to each other through holes passing through the elastic film with many bonded portions arranged at intervals. A region having the elastic film stretchable structure includes a stretchable region that elastically stretches and contracts together with the elastic film. The stretchable region includes a plurality of elastic films disposed so as to have an overlapping portion. The number of laminated layers of the elastic film in a region located in an intermediate portion of the stretchable region in an orthogonal direction (XD) orthogonal to a stretchable direction (ED) is different from that in each of second regions adjacent to both sides of the first region.

A micromagnetic device includes a first insulating layer formed above a substrate, a first seed layer formed above the first insulating layer, a first conductive winding layer selectively formed above the first seed layer, and a second insulating layer formed above the first conductive winding layer. The micromagnetic device also includes a first magnetic core layer formed above the second insulating layer, a third insulating layer formed above the first magnetic core layer, and a second magnetic core layer formed above the third insulating layer. The micromagnetic device still further includes a fourth insulating layer formed above the second magnetic core layer, a second seed layer formed above the fourth insulating layer, and a second conductive winding layer formed above the second seed layer and in vias to the first conductive winding layer. The first and second conductive winding layers form a winding for the micromagnetic device.

A multi-layer, super-planar structure can be formed from distinctly patterned layers. The layers in the structure can include at least one rigid layer and at least one flexible layer; the rigid layer includes a plurality of rigid segments, and the flexible layer can extend between the rigid segments to serve as a joint. The layers are then stacked and bonded at selected locations to form a laminate structure with inter-layer bonds, and the laminate structure is flexed at the flexible layer between rigid segments to produce an expanded three-dimensional structure, wherein the layers are joined at the selected bonding locations and separated at other locations.

The present invention relates to an electrically conductive film characterized by being able to undergo elastic deformation, having little residual strain rate and exhibiting stress relaxation properties. More specifically, the present invention relates to an electrically conductive film wherein the stress relaxation rate (R) and the residual strain rate (alpha), as measured in a prescribed extension-restoration test, are as follows: 20%≦R≦95% and 0%≦α≦3%.

This disclosure relates to using polyester films on building boards to enable improved surface coatings. The polyester film is preferably applied to a glass mat via an adhesive to form a laminate. This laminate is then bonded to the exterior surface of a gypsum board. The polyester film is advantageous because it allows for exterior surface coatings to be applied. In one embodiment, an exterior acrylic coating is applied to the polyester film. Boards constructed in accordance with this disclosure allow for exterior finishings to be achieved without the need for excessive finishing materials or steps.

New temporary bonding methods and articles formed from those methods are provided. In one embodiment, the methods comprise coating a device or other ultrathin layer on a growth substrate with a rigid support layer and then bonding that stack to a carrier substrate. The growth substrate can then be removed and the ultrathin layer mounted on a final support. In another embodiment, the invention provides methods of handling device layers during processing that must occur on both sides of the fragile layer without damaging it. This is accomplished via the sequential use of two carriers, one on each side of the device layer, bonded with different bonding compositions for selective debonding.

A cover panel, for at least partially transparently covering at least one display instrument in a vehicle, has a microstructure applied on at least one surface. The microstructure is suitable for scattering visible light which is incident on the cover panel. The at least one window region of the cover panel is cutout from the microstructure. A method for manufacturing such a cover panel uses a molding tool with an applied microstructure matrix for forming a microstructure on a part of the molding tool which is assigned to a surface of a molded cover panel. The parts of the molding tool which are assigned to window regions are cut out from the microstructure matrix.
