Abstract: An improved process for manufacturing glass coated wire, for example, a corona generating electrode having a dielectric coating layer of the type used in electrostatographic printing applications, wherein predetermined stresses are induced along the axial, radial, and hoop stress vectors present in the dielectric coating.

Abstract: A novel electroformed squeegee blade for the uniform deposition of printing material such as solder paste and the like onto printed wiring boards is disclosed. A method of fabricating the electroformed squeegee blade is also disclosed. The method of fabrication, which produces an electroformed squeegee blade having smooth, planar, and flat surfaces, involves electroforming at least one uniform layer of metal onto a conductive substrate and removing the substrate. Also disclosed is an apparatus and method that employ the electroformed squeegee blade to uniformly deposit printing material on printed wiring boards.

Abstract: A spray director incorporates structure that generates upstream turbulence for control of spray distribution and spray droplet size. A method of fabricating spray director utilizes a multilayer resist process in conjunction with a multilayer electroforming process.

Abstract: A zero sack volume fluid flow regulator generates upstream turbulence for control of fluid flow, fluid spray distribution and fluid droplet size. The fluid flow regulator includes a seal layer for selectively controlling fluid flow. The seal layer is resiliently movable relative to a base layer to selectively constrict a turbulence inducing intermediate channel within the regulator and selectively control fluid flow. A method of fabricating the fluid flow regulator utilizes a multilayer resist process in conjunction with a multilayer electroforming process.

Abstract: To prepare a screen printing stencil, a pattern of resist, having a complementary design to the final screen printing stencil, is applied to a conductive mandrel. A patterned layer is electroformed onto the exposed surface of the mandrel such that the layer corresponds to the exposed orifices of the pattern of resist. The resulting screen printing stencil can have an overgrowth geometry or a straight-wall geometry depending on the type of photoresist employed, and can be used in the electronic substrate fabrication and electronic assembly industries.

Abstract: To prepare a screen printing stencil, a pattern of resist, having a complementary design to the final screen printing stencil, is applied to a conductive mandrel. A patterned layer is electroformed onto the exposed surface of the mandrel such that the layer corresponds to the exposed orifices of the pattern of resist. The resulting screen printing stencil has raised edges surrounding orifices. The raised edges are placed against a surface of a substrate to be printed in use of the stencil. The screen printing stencil can be used for printing substrates in the electronic substrate fabrication and electronic assembly industries.

Abstract: A self-adhering base for a cathode ray tube has a circular array of connector pin apertures, three of which are sized to create a force fit with their associated pins. A first high voltage pin aperture is sized smaller than its associated pin, and the remaining two apertures, which are located approximately equidistantly from the first aperture, are slot-shaped. The slots are oriented to have their long axes intersect the first aperture. Such a self-adhering base is useful both as an in-process base during tube manufacture, and also as a permanent base on the finished tube.
