  • Patent number: 8905743
    Abstract: The invention relates to a hood for sucking-up fine particles, including: a mouth intended to be placed close to a wall, a base having a window through which a laser beam can pass, an intermediate portion between the mouth and the base, and a suction outlet disposed on the intermediate portion of the hood and designed to suck-up fine particles. The hood is characterized in that it comprises at least one air intake positioned near the base and, during operation, capable of creating a stream of air at the base of the hood so as to prevent fine particles from being deposited on the window.

  • Patent number: 8900507
    Abstract: A laser-engraveable composition comprises one or more elastomeric rubbers including at least 10 parts of one or more CLCB EPDM elastomeric rubbers, based on parts per hundred of the total weight of elastomeric rubbers (phr). The laser-engraveable composition further comprises 2-30 phr of a near-infrared radiation absorber and either 1-80 phr of an inorganic, non-infrared radiation absorber filler, or a vulcanizing composition that comprises a mixture of at least two peroxides. One first peroxide has a t90 value of 1-6 minutes as measured at 160° C., and a second peroxide has a t90 value of 8-20 minutes as measured at 160° C. This laser-engraveable composition can be used to form various flexographic printing precursors that can be laser-engraved to provide relief images in flexographic printing plates, printing cylinders, or printing sleeves.

  • Patent number: 8895114
    Abstract: The invention relates to a method for functionalizing the surfaces of adhesive closing parts which form, with correspondingly formed adhesive closing parts, an adhesive closure that can be repeatedly opened and closed. The surface energy of the adhesive closing part is modified by means of a proton and/or electron exchanging medium, especially in the form of donors or collectors, using high energy in such a way that the physicochemical properties of the material of the adhesive closing part can be adjusted without a coating and with ageing resistance, by the attachment of functional groups of the exchanging medium to the adhesive closing part material. The invention also relates to a device for carrying out one such method.

  • Patent number: 8852491
    Abstract: In a method of manufacturing an electroforming mold, a first photoresist layer is formed on an upper surface of a bottom conductive film of a substrate, and the first photoresist layer is divided into a first soluble portion and a first insoluble portion. A conductive material is thermally deposited on an upper surface of the first photoresist layer within a predetermined temperature range, to thereby form an intermediate conductive film. An intermediate conductive film is patterned. A second photoresist layer is formed on an exposed upper surface of the first photoresist layer after the intermediate conductive film is removed, and on an upper surface of the intermediate conductive film remaining after patterning. The second photoresist layer is divided into a second soluble portion and a second insoluble portion. Next, the first and second photoresist layers are developed, and the first and second soluble portions are removed.

    Abstract: An apparatus for forming a pattern using a laser is provided. The apparatus includes a pattern storing unit, a controller, a laser oscillating unit, an X-Y driver, a header unit, and a stage. The pattern storing unit stores data on light guide patterns of a discontinuous straight line shape. The controller transmits position signal of the light guide patterns to the X-Y driver and simultaneously, transmits a switching signal to the laser oscillating unit. The laser oscillating unit outputs a laser beam synchronized with a movement of the header unit. The X-Y driver moves the header unit and the stage. The header unit moves along a first guide rail. The stage moves along a fixed second guide rail in the front and rear direction of the light guide panel.
