  • Publication number: 20090311442
    Abstract: The invention relates to a method for pre-treating fibre reinforced composite plastic materials prior to painting, wherein the materials are subjected to a low pressure cold vacuum gas plasma treatment without preheating the materials. The invention further relates to a method for applying a painting layer on a fibre reinforced composite plastic material, wherein the method comprises the steps of pre-treating the material using a method according to any one of the preceding claims, and subsequently applying the painting layer to the pre-treated material.

  • Patent number: 6975453
    Abstract: The present invention comprises a multilayer inorganic anti-reflective coating with predetermined optical properties, for application on a flexible substrate. The coating comprises a stack consisting of five material layers, whereby the third layer is a dummy layer consisting of an electrically conductive material, preferably indium-tinoxyde, which provides the coating with an adjustable electrical sheet resistance of between 25 and 2000 ?/sq without thereby influencing its optical properties. The anti-reflective coating can be applied onto a flexible substrate (e.g. a polymer film) by means of a single 12 or double pass vacuum magnetron sputtering operation.

  • Patent number: 6594731
    Abstract: A method of operating a storage system comprising a main memory and a cache memory structured in address-related lines, in which cache memory can be loaded with data from the main memory and be read out by a processor as required. During the processor's access to data of a certain address in the cache memory, at which address certain data from the main memory which has a corresponding address is stored, a test is made to determine whether sequential data s stored at the next address in the cache memory; and this sequential data, if unavailable, can be loaded from the main memory in the cache memory via a prefetch, the latter only taking place when the processor accesses a predefined line section lying in a line.

  • Patent number: 6366013
    Abstract: A material is disclosed which is suitable for reducing the reflection of information displays such as a CRT, LCD, plasma tube, etc., and is characterised by an improved pencil hardness and excellent optical properties (lower average reflection, higher bandwidth). The anti-reflection material of the invention comprises an anti-reflective coating 20 and an optional top coat 10 on a flexible glass substrate 30 that is capable of being wound around a cylindrical core having a radius of 1.5 m. In a preferred method of the present invention the glass substrate 30 is provided with anti-reflective coating 20 using a continuous web coating process while being laminated to a polymer support 50 by using adhesive layer 40. Upon delamination (arrows 60) the adhesive layer 40 may remain fixed to glass substrate 30 (right embodiment of FIG. 1) or to polymer support 50 (left embodiment of FIG. 1).

  • Patent number: 6123787
    Abstract: The invention relates to a process for manufacturing a pore free powder metallurgical alloy article starting with a minor portion of Sn powder and a major portion of In.sub.2 O.sub.3 powder and comprising the steps of: substantially uniformly distributing and fixing the Sn powder on the surface of the In.sub.2 O.sub.3 powder by mixing and milling the powders in the presence of a process controlling agent such as an alcohol to form alloyed powders, and compacting the so alloyed powders at high temperature to form the article. The article has a good electrical conductivity and is usable as a target for plasma sputtering ITO compositions.

  • 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: 5790030
    Abstract: An antipiliferage tag comprising a soft-magnetic thin film (100) for use as an active element in an electronic article surveillance (E.A.S.) system. The film (100) has an easy axis (102) with a particular direction. The tag has been folded along at least one folding line (104) so that the tag comprises at least two layers which at least partially overlap with each other. The folding line (104) forms an oblique angle different from zero with the direction of the easy axis (102) so that the direction of the easy axis (102) in one layer is different from the direction of the easy axis (106) in another layer. In this way an antipiliferage tag which is insensitive to its orientation in a detection gate of an E.A.S. system is obtained.
