  • Patent number: 7815976
    Abstract: A method and apparatus for manufacturing a resin coated metal sheet. The method includes extruding a molten organic resin by heating from a T-die onto a metal sheet; dropping molten resin onto pre-rolls arranged between the T-die and lamination rolls, and bringing the molten resin in contact with the pre-rolls; and pressing the molten resin and the metal sheet by the lamination rolls to manufacture the resin-coated metal sheet. Electrically conductive bodies are arranged parallel to the widthwise direction of the pre-rolls, and the molten resin is dropped onto the pre-rolls in a state that an electric current is supplied to the conductive bodies, bringing the molten resin into contact with the pre-rolls by electrostatic pinning whereby an oligomer adhered to the pre-rolls is transferred to the surface of the molten resin and removed.

  • Patent number: 6292631
    Abstract: A mechanism, of a camera, for surely resetting a microcomputer at time of switching among a plurality of types of power sources. In the mechanism in which a manual operation dial for switching among the plurality of types of power sources is rotated to slide an electrical contact piece over a predetermined electrically conductive/non-conductive pattern so that a desired power source type is selected, an electric conductivity/non-conductivity between an IC and a negative terminal changes, immediately before an electric power across a positive terminal and the negative terminal is changed from “ON” to “OFF”, and immediately after the electric power is changed from “OFF” to “ON”. In association with the change, the IC outputs a reset signal to the microcomputer of the camera.

  • Patent number: 4189857
    Abstract: A decorative article in assembly with a decorative cover, including an inlay such as a tapestry or a photograph and preferably equipped with a stand, for use in the interior of a building comprises a plastic foam foundation, covered by a decorative covering with an informative inlay such as a photograph, a mirror, or a painting placed over the foundation and cover, the inlay being covered by a transparent sheet, the circumferential edge of the sheet being secured by a plurality of decorative pin heads, each pin head having its needle piercing through the sheet into the foundation for a tight fit of all the component parts.
