摘要： Magnetic thin film structures are disclosed including a laminate of a layer of nonmagnetic material sandwiched between first and second layers of magnetic material and at least one edge closure layer of magnetic material disposed on a side edge of the laminate with the edge closure layer being in magnetic contact with the first and second layers of magnetic material. The edge closure layer eliminates magnetic edge closure domains and magnetic edge-curling walls in the yoke and poletip regions, or in a fluxguide of a magnetic recording head to substantially eliminate Barkhausen noise and wall network instabilities. Multiple layer laminates are also disclosed having a plurality of nonmagnetic layers each of which are sandwiched between layers of magnetic material and wherein the laminate includes edge closure layers that contact all the magnetic layers. Several methods are disclosed for fabricating the laminate. In one class of technique, the side edges are deposited together with a top layer in a single plating operation. In an another embodiment, the side edge closure layers are separately plated. Another embodiment provides for a layer of antiferromagnetic material deposited between the nonmagnetic layer and one of the magnetic layers to provide additional anisotropy.

摘要： In the preferred embodiment, an improved electrochromic display device is disclosed wherein an acid-resistant, proton-conductive, nonporous polymer layer separates the electrochromic transition metal oxide film and the aqueous acidic electrolyte. The polymer layer preferably comprises an ultraviolet light-cured, plasticized poly (vinyl alcohol) that is thermally treated to render it acid insoluble. The polymer layer conducts protons between the electrolyte and the electrochromic layer to permit the desired electrochromic reactions to occur, but reduces film dissolution into the electrolyte to substantially extend the useful lifetime of the device.
摘要翻译：在优选实施例中，公开了一种改进的电致变色显示装置，其中耐酸，质子传导的无孔聚合物层分离电致变色过渡金属氧化物膜和酸性电解质水溶液。聚合物层优选包含经热处理以使其不溶解的紫外线光固化的增塑的聚（乙烯醇）。聚合物层在电解质和电致变色层之间导电质子以允许发生所需的电致变色反应，但是减少膜溶解到电解质中，从而基本上延长了器件的使用寿命。

摘要： In the preferred embodiment, a novel tungsten oxide film is presented for incorporation into an electrochromic display device wherein a surface of the film is in contact with an acidic aqueous electrolyte. The film comprises an underlying layer consisting of true amorphous, electrochromic tungsten oxide and an integral surface layer consisting of nonelectrochromic, random network amorphous tungsten oxide that is substantially less soluble in the electrolyte than the underlying electrochromic tungsten oxide. Preferably, the surface layer is formed by treating a vapor-deposited tungsten oxide film by exposure to a low energy plasma to restructure the molecular bonding at the surface without affecting the underlying tungsten oxide. When the treated film is incorporated into a display device, the surface layer minimizes dissolution of the film into the electrolyte to substantially extend the useful lifetime of the device, but readily conducts protons between the underlying layer and the electrolyte so as not to significantly interfere with device cycling.
摘要翻译：在优选实施例中，提出了一种新型的氧化钨膜用于结合到电致变色显示装置中，其中膜的表面与酸性水性电解质接触。该膜包括由真正的非晶体，电致变色钨氧化物构成的下层，以及由非电致变色随机网状无定形氧化钨组成的整体表面层，其与电致变色氧化钨相比在电解质中的溶解度低得多。优选地，通过暴露于低能量等离子体处理气相沉积的氧化钨膜来重构表面上的分子结合而不影响下面的氧化钨，形成表面层。当处理的膜被并入显示装置中时，表面层使薄膜溶解到电解质中最小化，从而基本上延长了器件的使用寿命，但容易地在下层和电解质之间传导质子，以免显着干扰设备循环
