An integral skin foam molded article includes: a skin formed by sewing a plurality of skin pieces in a hag shape; and a resin foam which is molded inside the skin integrally with the skin, wherein: at least one skin piece among the plurality of skin pieces has a surface material made of a natural leather, and includes a wadding material stacked on a back side of the surface material in a non-surface joined state and a lining material stacked on the wadding material; and in a shrinkage rate with respect to an in-plane compression load, a shrinkage rate of the liming material is smaller than a shrinkage rate of the wadding material.

A sub-centimeter structure includes a first structural component, a second structural component arranged proximate the first structural component, and a joint connecting the first and second structural components. The joint includes a material that has a first phase that is substantially rigid to hold the first and second structural components in a substantially rigid configuration while the material is in the first phase. The material of the joint has a second phase such that the joint is at least partially fluid to allow the first and second structural components to move relative to each other while the material is in the second phase. The joint interacts with the first and second structural components while the material is in the second phase to cause the first and second structural components to move relative to each other. And, the first and second structural components include a polymer.

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 peening method which can sufficiently improve fatigue properties of a lap fillet welded joint having a thin steel sheet as a base sheet, in which a knocking pin having a predetermined shape is continuously knocked as a series of knocking toward a direction inclined relative to the welding direction, the series of knocking is repeatedly performed in the welding direction, at that time, a knocking mark group made of a plurality of knocking marks formed by the series of knocking is superimposed on at least a part of an adjacent knocking mark group while an end part in the direction orthogonal to the welding direction of the knocking mark group is separated from an end part in the direction orthogonal to the welding direction of the adjacent knocking mark group.

A hermetic seal between an optical element and a metal mount or housing using a fluoropolymer. The fluoropolymer is dispersed along the interior edge of the metal mount. The metal mount and fluoropolymer are then heated to a temperature exceeding the melting point of the fluoropolymer. Once heated the optical element is pressed into the metal mount and allowed to cool. The metal mount, optical element and thickness of fluoropolymer are sized to provide an interference fit between the metal mount and optical element.

Various embodiments are directed to an airline carpet kit comprising a plurality of carpet components collectively forming a substantially continuous floor covering, for example, for use within an aircraft interior. Each of the plurality of carpet components comprises a tufted carpet backing having a plurality of carpet tufts extending from a back surface of the carpet backing and above a top surface of the carpet backing; and an edge strip comprising an amorphous plastic material, wherein the edge strip extends around a lateral edge of the carpet backing between a base portion embedded within a back surface of the carpet backing and an edge surface defining a perimeter edge of the carpet component. The edge surface of a first carpet component abuts an edge surface of an adjacent second carpet component to form an at least substantially continuous floor covering for an aircraft interior.

A high elongation ridge ventilation sheet for a sloping roof, having a coated composite aluminum membrane with multiple circular holes, each side of the coated composite aluminum membrane being bonded respectively with a folded composite aluminum membrane via a butyl adhesive tape for central linking, on a side of each folded composite aluminum membrane adjacent the coated composite aluminum membrane is arranged with a hot melt adhesive for connecting a polyester nonwoven fabric with each folded composite aluminum membrane, with the polyester nonwoven fabric covering the whole coated composite aluminum membrane. Further, a fabricating method therefor that realizes wholly dry construction; ridge ventilation sheets adopted on ridge locations not only make the whole roof prettier, but more importantly, enable air convection under the roof in a true sense, taking out extra dampness and heat, resulting in better energy saving effects, and extending life span for the roof.

A large area patterned film includes a first patterned area; a second patterned area; and a seam joining the first patterned area and the second patterned area, wherein the seam has a width less than about 20 micrometers. A method for tiling patterned areas includes depositing a predetermined thickness of a curable material; contacting a first portion of the curable material with a mold; curing the first portion of the curable material; removing the mold from the cured first portion of the curable material; contacting a second portion of the curable material with the mold, such that the mold contacts a portion of the cured first portion of the curable material; curing the second portion of the curable material; and removing the mold to yield a seam between the cured first portion of the curable material and the cured second portion of the curable material, wherein the seam has a dimension less than about 20 micrometers.

Printed active origami combines printed electronics with nanomaterial coated polymer based actuators to create active printed structures. The fabrication processes include the step of applying carbon nanomaterial coatings to polymeric films. Products produced by the processes include actuating materials, such as solid state actuators that can be used as active element(s) in a printable active origami robot.
