    摘要： In an electroforming method for making metal products having a pattern of openings separated by dykes using a mandrel in an electroplating bath, metal from the bath is deposited on at least two electrically mutually insulated regions. Said regions comprise at least one main pattern for product dykes to be formed, which main pattern is electrically insulated from at least one ancillary pattern for a reinforcement to be formed. In the method according to the invention, first the ancillary pattern is connected to a current source in order to form reinforcement thereon and in order to effect an electrical connection between the ancillary pattern and the main pattern by means of the growing metal. During the continuation of the method, reinforcement is thickened and the product dykes are formed. A strong product having different thicknesses is therefore obtained in one step. A mandrel suitable for use in the method is also described.

    摘要： A process for preparing a porous metallic body comprising the steps of: rendering a porous resin body electrically conductive, electroplating the conductive resin, and heating the electroplated resin to remove the resin, wherein the step of rendering the resin electrically conductive is conducted by coating the resin with a coating composition containing amorphous carbon particles as a conductive material. In the process, substantially spherical carbon particles may be used as the conductive material. The substantially spherical carbon particles are still preferably amorphous carbon. The thus obtained porous metallic body has reduced defect and more smooth skeleton in the porous body, is less likely to cause stress concentration upon application of bending and tensile force, has lower carbon content, and superior mechanical strength, and, therefore, the substrate is suitable as an electrode substrate for batteries.

    摘要： A new and improved orifice or nozzle plate for an inkjet printhead and method of manufacture wherein the orifice or nozzle plate thickness has been increased significantly to a value on the order of 75 micrometers or greater while simultaneously maintaining the integrity of the convergent contour of the multiple orifice openings formed therein. In a first embodiment of this invention, metal layer stacking through the use of successive electroforming processes is used to achieve a desired orifice plate structure, architecture and convergent orifice geometry. In a second embodiment of this invention, anisotropic electroplating on a metal surface and over the edges of an inorganic dielectric mask is used to produce this orifice plate of increased orifice bore thickness and convergent orifice bore geometry. In yet a third embodiment of the invention, a selected metal is plated upon a permanent insulating mandrel having a metal pattern thereon to form convergent orifice openings in the plated metal. Openings are then formed in the insulating layer which are aligned with electroplated convergent openings in the metal layer to thereby form a composite metal-insulator orifice plate of increased thickness and overall convergent orifice bore geometry.

    摘要： A method of fabricating an integral filter on a substrate includes: blanket depositing a base layer of a metallic material on a planar surface of the substrate; depositing a patternable material layer over the base layer of metallic material; patterning a plurality of grid lines in the paternable material layer to form a filter pattern; depositing metallic material in the grid lines of the filter pattern by electroplating, to form a filter over the base layer; removing the patternable material layer from the planar surface; and removing the base layer of metallic material at least between the grid lines of the electroplated filter. Preferably, the substrate is part of a fluid handling device, and therefore, includes a through-hole over which the filter is fabricated. Usually, the filter is fabricated prior to forming the through-hole. In one example, the fluid-handling device is a channel plate for a thermal ink jet printhead.
