  • Patent number: 6617012
    Abstract: A system and method for forming servo patterns on magnetic medium is disclosed. A magnetic film coated with a layer of styrene-acrylonitrile is stamped with a nickel stamper reproducing the negative image of the stamper pattern on the styrene-acrylonitrile. Ions are then accelerated towards the surface of the styrene-acrylonitrile, which stops the ions in the areas where the styrene-acrylonitrile is thick and allows the ions to penetrate through to the magnetic layer in the areas where the styrene-acrylonitrile is thin. The ions, which penetrate through to the magnetic layer, interact with the magnetic layer altering the magnetic layer's structure reducing its coercivity (Hc) and remnant moment (Mrt). This reproduces the stamped styrene-acrylonitrile pattern on the magnetic layer. The styrene-acrylonitrile is then removed by oxygen plasma etching the surface leaving behind a patterned magnetic medium.

    Abstract: An automotive lambda oxygen sensor is formed by electroless plating of a thin, catalytically active, conductive electrode uniformly on the outer surface of a zirconia thimble. The process includes forming a pristine zirconia solid electrolyte thimble and drilling out a cylindrical cavity in it. A porous outer surface suitable for producing crystallization sites is formed by dipping the unfired thimble in a zirconia slurry containing spray-dried microspheres and firing the coated thimble to densify the thimble and the microspheres and to produce cavities on the surface of the thimble. An inner platinum electrode is formed by conventional conductive ink painting on the axial cavity of the sensor, and the sensor is again fired. The surface is activated by immersion in an acetone chloroplatinic acid bath to form multiple crystallization points, heat treated, then plated in an electroless platinum bath to a desired thickness.

  • Patent number: 6342276
    Abstract: A very fine pixel pattern can be formed by first screen printing a conductive paste and electron-emitting carbon paste material in sequence before removing a predetermined portion of the screen-printed layers simultaneously such that remaining portions become a fine pixel pattern. This method not only enables fine pixel pattern formation but also provides an electrode/emitter structure that increases electron emission. Furthermore all these improvements can be made with less manufacturing time and cost.

  • Patent number: 6337119
    Abstract: Master discs and similar devices used in the production of digital data storage and recording discs and the like are produced with a substrate member which is provided with a layer of material which is applied to the substrate member in liquid form of a thickness greater than the surface roughness of the substrate member and of a thickness greater than any particulates present on the substrate member. The material layer is preferably a polymer such as epoxy, acrylic or styrene and is hardenable by exposure to UV light, heat, air circulation or catalytic reaction to provide a substantially smooth flat surface for receiving a data bearing film. The film may be treated to generate bumps or pits representing digital signals, for example, which are free of any defects resulting from surface roughness or contamination of the substrate member.

  • Patent number: 6315880
    Abstract: An automotive lambda oxygen sensor is formed by electroless plating of a thin, catalytically active, conductive electrode uniformly on the outer surface of a zirconia thimble. The process includes forming a pristine zirconia solid electrolyte thimble and drilling out a cylindrical cavity in it. A porous outer surface suitable for producing crystallization sites is formed by dipping the unfired thimble in a zirconia slurry containing spray-dried microspheres and firing the coated thimble to densify the thimble and the microspheres and to produce cavities on the surface of the thimble. An inner platinum electrode is formed by conventional conductive ink painting on the axial cavity of the sensor, and the sensor is again fired. The surface is activated by immersion in an acetone chloroplatinic acid bath to form multiple crystallization points, heat treated, then plated in an electroless platinum bath to a desired thickness.

  • Patent number: 6299947
    Abstract: A method in accordance with our invention for providing texture bumps on a substrate comprises the step of forming elliptical ridge-shaped bumps on the substrate. In one embodiment, substrate is used in the manufacture of a magnetic disk used in a disk drive. The elliptical bumps cause less vibration of the read-write head than circular bumps. The elliptical bumps also provide reduced friction between the disk and a read-write head during use.

  • Patent number: 6299940
    Abstract: A glass ceramic article is decorated with ceramic paints in a screen printing process in accordance with which two, mutually corresponding grate-shaped structural elements are arranged on the surface of the glass ceramic article to form a closed, full-surface decorative coating so that the surface beneath it is not visible. The first structural element consists of ceramic paint members covering respective separate parts of the surface with intermediate spaces between them, while the second grate-shaped structural element consists of other ceramic paint members covering the intermediate spaces between the ceramic paint members of the first structural element but only at most overlapping edges of the ceramic paint members of the first structural element without covering them. The closed full-surface decorative coating can have a two-color pattern, such as a black and white pattern.

  • Patent number: 6296900
    Abstract: A hidden image game piece and a method by which a hidden image game piece is produced. A first pattern of colored ink is deposited on a transparent or highly translucent substrate at 110-180 density, forming the image which is to be hidden. Then a second pattern of colored ink, of a different color than first pattern's ink, is deposited upon the substrate on top of the first pattern, at 90-170 density. When the game piece is flooded with additive light of the same color as the second pattern's ink, the previously concealed image, composed of the first pattern's ink, becomes perceptible. Because a transparent or highly translucent substrate is used for the game piece, and because the density of the ink application is controlled within specific ranges, this game piece may be used with a computer monitor, or with other low-intensity sources of additive light.

  • Patent number: 6284317
    Abstract: The present invention relates to methods of derivatizing semiconductor surfaces, particularly porous silicon surfaces with silicon-carbon units. The derivatization occurs through the direct addition of an organometallic reagent in the absence of an external energy source such as heat and photo- or electrochemical energies. The method of the invention allows the formation of unique intermediates including silicon hydride units bonded to metal ions. Because of these unique intermediates, it is possible to form previously inaccessible silicon-carbon units, for example where the carbon atom is an unsaturated carbon atom. Such inaccessible silicon-carbon units also include silicon-polymer covalent bond formation, in particular where the polymer is a conducting polymer. Thus, the present invention also provides a novel semiconductor surface/polymer junction having improved interfacial interactions.

  • Patent number: 6281270
    Abstract: Color images with high fixation comparable to that of silver salt photographic images are formed on printing papers, using aqueous ink compositions by ink jet recording. Color images thus formed have high saturation and high resolution. An intercalated compound capable of fixing water-soluble dyes to a printing paper due to the intercalation based on ion-exchanging between them is incorporated into the dye-receiving layer 2 of the paper, on which color images are formed by ink jet recording using an aqueous ink composition containing a water-soluble dye. The content of the intercalated compound in the layer 2 is from 10 to 90% by weight. As the intercalated compound, montmorillonoids are preferred when water-soluble cationic dyes are used while hydrotalcite-group minerals are preferred when water-soluble anionic dyes are used. FIG. 1 is selected.
