    Abstract: Antimicrobial films are disclosed herein. The antimicrobial films are configured for application to surfaces, particularly to surfaces with which humans and animals come into contact. The antimicrobial films include a substrate layer and an antimicrobial layer. The substrate layer is generally a polymer, such as polyethylene. The antimicrobial layer is generally a composition of an antimicrobially-active ingredient dispersed in a dispersant. Typical dispersants include aqueous-based or solvent-based components (e.g., inks, primers, or varnishes). Antimicrobial films, as described herein, may be affixed to surfaces using an adhesive. Alternatively, the antimicrobial films may be applied to a surface using a heat-shrink process.

  • Patent number: 6114056
    Abstract: A magnetic element comprises a granular magnetic film which has ferromagnetic fine particles dispersed in a dielectric matrix and does not display superparamagnetism and further possesses a finite coercive force, and a ferromagnetic film. A granular magnetic film and a ferromagnetic film are stacked or arrayed along one surface of a substrate and constitutes a ferromagnetic tunnel junction film. In the ferromagnetic tunnel junction film, the granular magnetic film functions as a barrier. Of the granular magnetic film and the ferromagnetic film, by varying spin direction of one ferromagnetic film through an external magnetic field, a giant magnetoresistance effect is manifested. Such a magnetic element is characterized in that magnetoresistance change rate is large, saturation magnetic field is small, resistance of the element can be controlled to an appropriate value, performance is small in its variation and stable.

  • Patent number: 6083631
    Abstract: A product and a process for producing a matrix and a tool for use in abrasive or cutting applications including a base tool structure which may be armed with a plurality of triangular or conically shaped structures 24B consisting of abrasive particles 32 bonded together in a braze metal 38. The structures 24B may be prepared in a manner which provides a selectable rake angle. Rake angles including negative 46, neutral 46' and positive 46" may be produced. The process is accomplished by diffusing magnetizable abrasive particles on a release mechanism which has been placed on a reusable fixture 10 consisting of a plurality of balls 16 secured to a magnetized surface 14. The particles 32 stack to form structures 24 which are then encapsulated in a braze paste 26. The axis of the structures 24 is aligned with the applied magnetic field. The cones are symmetrical if the magnetic field emanates perpendicularly from the magnetized surface.

  • Patent number: 6004683
    Abstract: A base metal repair tape includes a first layer formed braze alloy bonded together with fibrillated polytetrafluoroethylene, a second layer formed from powdered base metal comprising oxygen-sensitive superalloy bonded together by fibrillated polytetrafluoroethylene and a third layer comprising a brazing alloy bonded together by fibrillated polytetrafluoroethylene. This is used to repair base metal by placing the first layer on the base metal and brazing the base metal powder so that the brazing alloy melts and diffuses into the base metal powder bonding it to the surface of the article. This permits the braze powder to be bonded to the base metal surface with minimal distance between the base powder particles. The number of alternating layers of base metal and braze alloy can be increased to increase the thickness of the repair. This can also be used to form small intricate parts.

  • Patent number: 5904966
    Abstract: A laminated structure is obtained by hot isostatic pressing. The structure comprises a first metallic outer layer (produced by powder metallurgy) on one side, a second metallic outer layer on the other side which can form a brittle intermetallic phase and/or a brittle ordered phase with the first side, and a ductile metallic intermediate layer, the layers possessing mutually different coefficients of thermal expansion, whereby the intermediate layer acts as a diffusion barrier against the formation of the aforementioned brittle intermetallic phases or ordered phases. The invention also concerns a manufacturing method for the structure and an application of same as a cathode in a plasma sputtering unit.

  • Patent number: 5812926
    Abstract: A hard facing alloy is applied to a surface of a substrate by making a mixture of at least two constituents whose net composition is the desired hard facing alloy composition. The constituents have different solidus temperatures, at least one of which is above a processing temperature of the substrate and another of which is below the processing temperature of the substrate. In one preferred approach, the mixture is prepared by pressing and lightly sintering the constituents in the form of powders, so that the mixture retains its shape and can be attached to the substrate surface. Then the substrate is heated to the processing temperature and maintained for a time sufficient to permit interdiffusion of the several different phases toward a homogeneous hard facing alloy composition uniformly through a major portion of the volume.

  • Patent number: 5496650
    Abstract: Process of imparting conductivity to a three-dimensional net-shaped porous sheet can be performed efficiently before carrying out electroplating process. Fine metallic powders are applied to the porous sheet made of a foamed sheet, a nonwoven sheet, a mesh sheet or a plurality of sheets layered one on the other, so that a conductive metallic layer is formed on the porous sheet. Then, an electroplated layer is formed on the surface of the conductive metallic layer. The conductive metallic layer remains when the porous sheet burned out. Consequently, a metallic layer of the conductive metallic layer and the electroplated layer forms the metallic framework of the metallic porous sheet.
