  • Patent number: 10221527
    Abstract: A dry polymer cement overlay for trafficked pavement substrates (both asphalt and concrete). The dry polymer cement overlay is a thin overlay that can handle the load of traffic in a relatively short time and has a relatively long life cycle. Moreover, the dry polymer cement overlay can hold aggregate that is applied on the surface of dry polymer cement overlay before it cures in order to provide a friction surface. A stencil is used during application of a dry polymer cement layer to provide a patterned overlay that includes patterns separated by gullies. The patterned dry polymer cement overlay exhibits improved performance including short and long term substrate adhesion, reduced risk of delamination, safety through improved surface runoff and enhanced visibility, improved macro and micro friction, reflective crack management, and withstands higher deflections under heavy loads. The patterned dry polymer cement overlay may also reduce noise and improve aesthetics.

    Abstract: The present invention provides a hot press molding method for molding a heated metallic plate (K) using a molding die (20, 60) comprising an upper die (21) and a lower die (20). According to the method, the heated metallic plate is arranged between the upper die and the lower die, the upper die and the lower die are brought together, and the metallic plate held between the dies is pressed. After the metallic plate is pressed, a refrigerant in the form of a liquid or mist is supplied via a plurality of supply holes provided to the lower die to a surface of the metallic plate held between the dies, and once the refrigerant has finished being supplied, a gas is sprayed onto the surface of the metallic plate via the plurality of supply holes. It is thereby possible to remove, with maximum speed, liquid refrigerant adhering to the metallic plate when the supply of liquid refrigerant is stopped.

  • Patent number: 9199741
    Abstract: Global icephobic performance of a passive deicing structure may be achieved by including one or more ice nucleating zones that are configured, preselected, and/or arranged to promote selective formation of ice. Ice nucleation zones may be configured, preselected, and/or arranged to form ice that is weakly adherent and, hence, may be removed by sufficient shear force. Ice nucleation zones typically include nucleating particles to promote selective ice formation. Passive deicing structures typically include both ice nucleation zones and ice resisting zones, arranged to facilitate ice removal by shear force. Passive deicing structures may be used on apparatuses such as vehicles (e.g., aircraft) to mitigate the effects of ice formation on exposed surfaces.

  • Patent number: 8256493
    Abstract: A surface treatment method includes covering a surface of a casting mold with a carbon film containing at least one type of nanocarbon selected from the group of carbon nanocoils, carbon nanotubes and carbon nanofilaments, and further applying fullerenes to that surface. With this surface treatment method being performed on a surface (a cavity surface, etc. of a casting mold) making contact with a molten casting material such as aluminum, etc., sticking of the molten casting material to the mold is inhibited, release resistance of the product is reduced, and release effectiveness is improved. The release effectiveness lasts longer than in the case of a conventional carbon film.

  • Patent number: 7997889
    Abstract: A hard mold and method of preparing the mold is disclosed. The hard mold is designed for manufacturing articles having various shapes and patterns. The shaping mold includes a layer of hardened material provided over the entire surface of the selected master. The inventor has found that a polyurea coating or other polyurethane hybrid is preferred. Once the layer of hardened material has dried, the surface of the hardened material is sanded with a 20-40 grit sandpaper and a layer of polyester resin is then applied to the layer of hardened material. Once the polyester resin is applied, multiple layers of vinyl ester are applied to the polyester resin to prevent the polyester resin from shrinking. In the preferred embodiment, the application includes at least three (3) layers of vinyl ester.

  • Patent number: 7988889
    Abstract: An exemplary method for making a mold used for molding lenses includes the following. First, a base is provided. The base has parallel lines marked on a surface thereof. Second, a dispenser is provided. The dispenser dispenses lumps of molding material on selected positions on the surface of the base guided by the lines. Third, a roller is provided. The roller has a peripheral side surface. The peripheral side surface has spaced molding surfaces defined thereat, each molding surface corresponding to a surface of a lens to be formed. The roller is applied above the base, with the molding surfaces press-molding the lumps of molding material, thereby forming molding portions on the base. Thus, a mold including the base and the molding portions formed on the base is obtained.
