    Abstract: A device and a method for improving uniformity of a film, which uses the controllable magnets instead of permanent magnets and controlling the magnetic polarity by a programmable control device, so that when the clamping frame is aligned with the mask, the magnetic polarity of the electromagnet is controlled to generate an alternating magnetic field which will affect the coating material sprayed from the evaporation source. With the help of the alternating magnetic field, the coating material will be evenly sprayed to a substrate. Consequently, uniformity of the film for coating and the yield of products are improved.

    Abstract: A wire grid polarizer formed as a self-assembled coating on a substrate surface. Metal or other conductive nanowires are coated with a transparent dielectric material having a thickness approximately equal to one-half of the desired WGP wire spacing or pitch. A suspension of coated nanowires in a chromonic liquid crystal is shear-coated onto an aligned substrate and dried. The chromonic liquid crystal, a solution of dye molecules and water, forms an orderly structure and induces the nanowires to align with their longitudinal axes parallel to the shear direction and/or alignment direction. The polarizer has a minimum polarizing wavelength determined by an average lateral spacing of nanowire segments. The polarizer has a transmissivity and a contrast ratio determined by the width of the nanowire segments.

    Abstract: Methods for making battery electrode system are disclosed herein. In an example of the method, a mixture of a polymer binder, an active material and a conductive filler is deposited on a current collector. The deposited mixture is exposed to an external field having a field direction that is normal to a surface of the current collector. The exposure aligns, outward from and normal to the surface of the current collector, the active material and the conductive filler to form a plurality of discrete structures that extend outward from and normal to the surface of the current collector and are respectively aligned with a field line of the external field. Each of the plurality of discrete structures includes some of the active material and some of the conductive filler.

  • Publication number: 20130089733
    Abstract: The geometric stiffness of structural sheet metal panels, such as those employed in motor vehicles, may be increased, without major increase in the mass of the panel, by application of a coating of a structural polymer. However conventional means of applying such a polymer layer require multiple applications to achieve a desired thickness. By incorporating magnetic particles in a resin, and subjecting the resin to a magnetic field as it is applied, the desired thickness may be achieved in a single application. Embodiments appropriate to the application of such a resin to both magnetic and non-magnetic materials are described.

    Abstract: [Problems] To have a thin film suitably function even when the thickness of the thin film is reduced. [Means for Solving Problems] Provided is a method for manufacturing a magnetic recording medium by forming a thin film on a substrate (12). The method is provided with a thin film forming step of forming the thin film by using a substance brought into the plasma state as a material. In the thin film forming step, the thin film is formed by using a material substance gathering means (30) for gathering the substance brought into the plasma state to the periphery of the substrate. The material substance gathering means (30) gathers the substance brought into the plasma state, for instance, to the periphery of the substrate (12) by generating a magnetic field at the periphery of the substrate (12).
