  • Patent number: 10961415
    Abstract: Laminates of polymeric films and solvent-based polyurethane adhesive formulations for preparing them are provided. The adhesive formulations include a hydroxyl-terminated polyester that forms crystalline polyester domains after reaction with an appropriate polyisocyanate, but prior to completion of cure. The result is an adhesive layer that substantially enhances the oxygen barrier properties of the adhesive and, therefore, of the laminate as a whole, while offering desirable convenience of application even at relatively low temperatures. The laminates may also exhibit desirable retention of barrier properties following flex-cracking.

  • Patent number: 7834292
    Abstract: A method is provided for welding a laminated metal sheet to a workpiece. The laminated metal sheet includes an outer metal sheet and an inner metal sheet bonded together by a polymer material that impedes the flow of weld current. A punch is applied against the outer metal sheet and driven through the laminated metal sheet to create a hole and also create an annular metallic burr that bridges across the polymer material layer between the outer metal sheet and the inner metal sheet. A weld electrode is positioned against the outer metal sheet at the punched hole and weld current is conducted through the first annular metallic burr to create an electric resistance weld between the laminated metal and the workpiece.

  • Publication number: 20100206475
    Abstract: Provided is an anode bonding method by which a silicon substrate and a glass substrate are well anodically bonded without generating positional shift, even when an electrode cannot be arranged on a surface on the opposite side to a bonding surface of a glass substrate and the bonding surface is large. The method for anodically bonding the glass substrate and the silicon substrate is provided with a step of placing on the glass substrate the silicon substrate whereupon a through hole is arranged; a step of bringing the anode electrode into contact with the surface of the overlapped silicon substrate opposite to the surface facing the glass substrate, and bringing an cathode electrode into contact with the glass substrate through the through hole arranged on the silicon substrate; and a step of applying a direct current voltage to the anode electrode and the cathode electrode in a state where the glass substrate and the silicon substrate are heated.

  • Publication number: 20100193664
    Abstract: This invention relates seed layers and a process of manufacturing seed layers for casting silicon suitable for use in solar cells or solar modules. The process includes the step of positioning tiles with aligned edges to form seams on a suitable surface, and the step of joining the tiles at the seams to form a seed layer. The step of joining includes heating the tiles to melt at least a portion of the tiles, contacting the tiles at both ends of at least one seam with electrodes, using plasma deposition of amorphous silicon, applying photons to melt a portion of the tiles, and/or layer deposition. Seed layers of this invention include a rectilinear shape of at least about 500 millimeters in width and length.
