An imprint lithography apparatus having a first frame to be mounted on a floor, a second frame mounted on the first frame via a kinematic coupling, an alignment sensor mounted on the second frame, to align an imprint lithography template arrangement with a target portion of a substrate, and a position sensor to measure a position of the imprint lithography template arrangement and/or a substrate stage relative to the second frame.

Methods and structures are disclosed. An example method includes: rotating a tubular mandrel about a longitudinal axis of the tubular mandrel; depositing a composite material on an inner surface of the tubular mandrel to form a composite tubular member on the inner surface of the tubular mandrel; inserting and expanding an inner expandable mandrel within the composite tubular member to cause the inner expandable mandrel to press the composite tubular member against the inner surface of the tubular mandrel; curing the composite tubular member; removing the inner expandable mandrel; placing a frame within the composite tubular member; and removing the tubular mandrel so as to obtain the composite tubular member with the frame placed therein.

An FRP material has a circular arc part, and a member fixed to the circular arc part. The FRP forming system has a portion-pressing device, a member positioning mechanism, and a transport device configured to form the FRP material as a single body of a circular arc-shaped FRP part. The FRP material may comprise a single layer prepreg or a plurality of prepregs that have been layered. The portion-pressing device has upper and lower molds sandwiching a portion of the FRP material in a radial direction orthogonal to the circular arc part, and compresses intermittently a portion of the FRP part. The member positioning mechanism locates the position of the member relatively to the upper or lower mold. The transport device moves the portion of the FRP material that is compressed by the portion-pressing device. The portion-pressing and the transport are repeated to form the FRP part.

A method of producing a sealed structure, the method including: preparing a substrate and a curable resin composition in a liquid form; and sealing the substrate with the curable resin composition, to form a sealed body including the substrate and a cured product of the curable resin composition. The sealing step includes: printing the curable resin composition onto the substrate, to cover the substrate with a first coating film of the curable resin composition; and compression-molding the first coating film and the substrate together using a mold, with a pressing surface of the mold abut against the first coating film, to convert the first coating film into a second coating film. A ratio of a projected area S1 of the first coating film onto the substrate to a projected area S2 of the second coating film onto the substrate: S1/S2 is 0.9 or more.

A method of preparing a bipolar plate for a fuel cell is disclosed. The method includes (a) using an electrically conductive filler and a polymer binder to prepare a bipolar plate blank, (b) vacuum-sealing the bipolar plate blank in a metal foil bag, (c) applying hot isostatic pressing to the bipolar plate blank vacuum-sealed in the metal foil bag at a pressure greater than 100 MPa and a temperature of 150-400° C., and (d) peeling the bipolar plate blank that has undergone the hot isostatic pressing from the metal foil bag, and thereby obtaining the bipolar plate. A bipolar plate prepared by the method is also disclosed.

The invention disclosed herein is an automotive acoustic panel including a porous sound-absorption material made from a polymer and an expanded perlite. One or more silane compounds may be coupled or coated onto the expanded perlite while a coupling agent and a chemical foaming agent may additionally be added to the automotive acoustic panel.
