The gasket (13) has a groove (22) provided in the circumferential surface portion (17) thereof as extending circumferentially thereof. The groove (22) has a depth of not less than 0.8D (m), preferably not less than D (m), wherein D (m) is the thickness of a portion of the lamination film (15) present in the circumferential surface portion (17) of the gasket (13).

Foldable composite structures and methods for fabricating foldable composite structures are provided. For example, a method comprises selectively applying a rigidifying substance to a sheet of composite material to define a plurality of hinges; allowing the rigidifying substance to cure; and folding the sheet of composite material along the hinges to form the composite structure. As another example, a method comprises laying out flat a sheet of composite material; masking a plurality of hinges on the sheet; applying a polymer to a sheet face; curing the polymer; removing the masking; and folding the sheet along the hinges to form the composite structure. An exemplary foldable composite structure comprises a planar sheet of composite material folded to define a plurality of surface segments and a plurality of hinges. A portion of the hinges form peaks and the remainder of the hinges form valleys. The hinges are defined between adjacent surface segments.

A duct of fiber material and binder agent, at least two fold lines are present lengthwise for providing a foldability of the duct by weakened material along the fold lines. The duct is pushable into a folded state and the material remembers the original shape and return to its original shape when released from a folded state. A method of manufacturing a duct: applying a web of origin fiber material with binder agent to a core and compressing the web by an outside form under the influence of heat against the core, wherein the core and/or the outside form is provided with a number of lengthwise ridges corresponding to the desired number of fold lines, to a third of the original thickness of the sides and at the ridges a tenth to a twentieth of the original thickness, and in that the fiber and binder agent web weighs 1.5-3 kg/m.sup.2.

A blank for a box made from an expandable material, which is initially molded to be substantially flat and in which folds forming hinges are to be made to enable the formation of the box. The tooling defines the shape of the blank is such as to provide a thickness of the expanded material that is less than the thickness of a major portion of the blank, in which folds are to be made having defined edges, generally in the direction of each fold; the fold and subsequently applying pressure along an area where folds are to be permitted to reduce the blank are made without removing material therefrom for providing hinges to permit formation of the box. A related method for making the blank and a box that is made from the blank are further provided.

A synthetic polymer film whose surface has a plurality of raised or recessed portions, wherein a two-dimensional size of the plurality of raised or recessed portions is in a range of not less than 0.5 m and not more than 3 m when viewed in a normal direction of the synthetic polymer film, the synthetic polymer film has a crosslink structure and contains an organic carboxylic acid, at the lapse of 5 minutes since placing a 200 L drop of water on the surface of the synthetic polymer film, a pH of an aqueous solution is less than 4, and an area equivalent circle diameter of the aqueous solution is not less than 20 mm, and at the lapse of 60 seconds since placing a drop of water on the surface of the synthetic polymer film, a static contact angle of the water drop with respect to the surface is less than 3.

An optical element includes a substrate, a plurality of reflection layers disposed on one side of the substrate, an absorbing layer disposed on a side of the reflection layers that is opposite to the substrate, and an oxide film that covers the absorbing layer and portions between any two adjacent reflection layers. The reflection layers are arranged in a striped manner in plan view. The oxide film is made of an oxide of a material contained in the absorbing layer.

Doors for motor vehicles include door trim panel assemblies having multiple door trim panels held together at attachment points. A door trim panel includes a weakened perimeter formed from a series of apertures in the panel, creating a predetermined breakaway point where the assembly will rupture in the event a load is applied. Methods for tuning the durability of a trim panel assembly include a repeatable cycle in which pins are selected and inserted in a mold at varying positions. During injection molding, the pins form apertures to create a predetermined breakaway point. Changing the size, shape, and location of the pins allows tuning of the durability and properties of the breakaway point. Injection molds have variable pin placement capability to facilitate the method.

Disclosed herein is a processing method for forming a plurality of quadrangular prisms on a plate-shaped substrate having a product area. The processing method includes the steps of preparing an excess-sized plate-shaped substrate having an excess area surrounding the product area, cutting the excess-sized plate-shaped substrate in a first direction by using a cutting blade to thereby form a first cut groove extending in the first direction, cutting the excess-sized plate-shaped substrate in a second direction perpendicular to the first direction by using the cutting blade to thereby form a second cut groove extending in the second direction, filling the first cut groove and the second cut groove with a resin, and cutting the excess-sized plate-shaped substrate along the boundary between the product area and the excess area by using the cutting blade to thereby remove the excess area from the excess-sized plate-shaped substrate.

An imprint apparatus including a mold holding unit configured to hold a mold, an adjusting unit configured to adjust a pressure difference between a first pressure on a second surface on an opposite side of a first surface on which a pattern of the mold held by the mold holding unit is formed and a second pressure in a first space between a substrate and the first surface of the mold, and a control unit configured to control an imprint process, wherein the imprint process includes a separation process of separating the mold from a pattern made of a cured product of an imprint material on the substrate, and the control unit controls, in the separation process, the adjustment of the pressure difference by the adjusting unit so that the first pressure is smaller than the second pressure.
