Patent EP-0257184-A1 (EP)
Inventor: HESTERMAN VICTOR W
IPC: G11B5/84
Filed: 1987-03-31
Abstract: The manufacture of digital magnetic recording discs (l-2l) for computer disc drives requires the monitor­ing and control of the M-H hysteresis loop properties (3-3l, 3-33, 3-35, 3-37) of the magnetic film (l-l5) deposited on the disc substrate (l-l9). Several methods exist for measuring this M-H hysteresis loop, but they all have serious disadvantages. One method consists of cutting samples and measuring them with a vibrating sample magnetometer. This is a destructive test and requires a lot of time per sample. Another method uses the Kerr-rotation of polarized light. However, it samples only the magnetization of the surface and cannot determine the magnetic thickness of the film. A third method magnetizes the entire disc and samples a large region along a diameter. This method cannot distingu­ish between the top and bottom films of the disc, and cannot resolve circumferential variations of the M-H loop properties. The method of this invention solves these problems by measuring a small part of one surface of the disc (l-2l) nondestructively using a special balanced head (l-l) having two air gaps (l-ll, l-l2). It is fast, requiring only about 2 minutes per measurement and has good reproducibility.

Abstract: A surface-active composition is provided which comprises phosphatidylcholine and phosphatidylethanolamine, wherein at least 3 wt.% of the phosphatide is lysophosphatidylethanolamine and wherein the hydrolysis ratio of the degree of hydrolysis of phosphatidylethanolamine and the degree of hydrolysis of phosphatidylcholine is higher than 1.5. The composition is particularly suitable for use as emulsifying agent in edible fat-containing products, especially as anti-spattering agent in, for example, margarine. The surface-active composition can be suitably prepared by fractionating vegetable lecithin with, for example, a lower alcohol, partially hydrolyzing the insoluble fraction and recombining the partially hydrolyzed insoluble fraction with the alcohol-soluble fraction.

Abstract: A halftone image printing device for printing an image consisting of picture elements arrayed in a zig-­zag fashioning. Each picture element is composed of dots forming a quasi-diamond-shaped matrix. The dot matrix is a 2 (row) × 3 (column) matrix with two additional dots located at the top and bottom, respectively. The range of optical density, within which the densities represented by the picture elements fall, is segmented into sub-ranges. Different heating-resistors are assigned to each sub-range of density. The dots printed by the heating-resistors assigned to any sub-range of density forms a "dot pattern" of a specific shape. The first dot pattern has one dot printed on the upper-­central part of the rectangular matrix. The second dot pattern has there dots forming an L-shaped pattern, the first dot printed on the upper-central part of the matrix, the second dot printed above the first dot, and the third dot printed to the right of the first dot. The third dot pattern consists of five dots forming a cross, the first dot printed on the upper-central part of the matrix, the second dot printed above the first dot, the third dot printed to the right of the first dot, the fourth dot printed below the first dot, and the fifth dot printed to the left of the first dot. And the fourth dot pattern consists of five dots forming a cross and an additional dot printed immediately below the cross. Of the dots of each dot pattern, the dot on which energy concentrates more than any other dot assu­mes the same location for all dot patterns.

Abstract: A strength enhancing composition for treating textile materials in the sizing or dyeing process has been developed by the encapsulation or occlusion of colloidal silica particles with a water reducible polyester resin of intermediate molecular weight. The complex formation of the resin colloidal silica species is accomplished in an aqueous medium. The resin is prepared from isophthalic acid, diethylene glycol and trimellitic axhydride followed by neutralization with amine containing material to render the resin reducible in water. The composition may be combined with any of the conventional size materials, i.e. polyvinyl alcohol, starches, lubricants, etc., to enhance the performance of the sizing composition. The silica/resin complex may be formed in situ, or may be preformed, dried and pulverized for later use or for mixing with conventional, dry, sizing materials. The composition may be applied to textile yarns using conventional equipment, such as yarn slashers or dye machines, with the treated textile material having enhanced strength and performance characteristics.

Abstract: To simplify manufacture of plated metal parts with high corrosive resistance, especially suitable for use as sealing lids or cover elements for semiconductor packages, a substrate (12) of Kovar, or Alloy 42, which are nickel-containing iron alloys, are electroplated with a base layer (14) of a metal having an electromotive potential high with respect to that of the substrate, over which an intermediate layer is electroplated. The intermediate layer (16) has an electromotive potential which is low with respect to the base layer; and over that a cover layer (18) is plated which has an electromotive potential similar to that of the base layer. A difference of about 1.2 volts of electromotive potential between the intermediate layer (16) with respect to the base layer (14) and the cover layer (18) is desirable. Suitable metals are gold-nickel-gold combinations, in which the gold layers should be over 10 microinches (0.25 micrometer) thick, preferably and in order to meet MIL-STD 883C, about 25 to 50 microinches (0.64 to 1 .27 micrometers) thick. The intermediate nickel layer (16), and preferably about 150 microinches (3.82 micrometers) thick, has an electromotive potential which is at the negative side of the electromotive series. Pin holes through the three layers may cause, under the influence of a corrosive atmosphere, migration of ions up to the base layer but, due to the arrangement of electromotive potential of the intermediate layer (16) and the cover layer (18), will not extend further so that the corroded substrate material will, effectively, form a plug for the pin hole and prevent progression of corrosion.
