Abstract: A multilayered ceramic capacitor having internal electrodes comprising a substantially single-crystal metallic powder as a conductor, the powder having been produced by spraying a solution containing at least one metal salt to form droplets and heating the droplets to a temperature higher than the decomposition temperature of the metal salt and the melting point of the metal. When the metal salt forms an oxide at a temperature not higher than the melting point of the metal, the droplets are heated to a temperature higher than the decomposition temperature of the oxide. The multilayered capacitor is free from generated cracks in the ceramic material.

Abstract: An electrically heatable windshield with a hidden bus bar configuration. A border of opaque ceramic material, preferably a lead borosilicate enamel, is bonded to an interior surface of the transparency about its periphery. Opposing electroconductive bus bars, preferably a low frit content silver-containing ceramic material, are bonded to the ceramic material so that the entire inner edge of the bus bar overlays a portion of the ceramic material and is spaced from the inner edge of the border, providing an intermediate portion of the border between the bus bars and transparency surface that is not covered by the bus bars. An electro-conductive coating is applied to the transparency to interconnect the bus bars and covers to the inner surface of the transparency, the bus bars and the intermediate portion of the ceramic material border so that electric current flowing between the bus bars must flow through the portion of the coating that covers the intermediate portion of the border.

Abstract: A hanger for a power factor capacitor and method of attachment by brazing reduces metallurgical changes that can lead to cracks in the tank wall from welding. The hanger has a base plate with a circular opening and a raised shoulder that provides a single ring of contact between the tank wall and hanger. A ring of brazing alloy is placed within the opening on the tank wall. Through induction of electric current, the brazing alloy melts and flows resulting in a complete braze between the hanger and the tank wall which is accomplished at a much lower temperature than other welding techniques.

Abstract: The mirror assembly uses a non-reflective conductive coating as a heating element for preventing fog formation on a mirror exposed to a humid environment such as is found in a bathroom. As compared to conductive reflective mirror coatings, the non-reflective conductive coatings used in this invention have a relatively high resistance, which allows high reflectivity mirrors to be made fog-free. The conductive coatings may be split into separate conductive elements with one or more scribe lines in order to control the length of the conductive path from inlet bus to outlet bus. The buses may be made from an ultra thin foil tape, which can be adhered to the conductive coatings, and which is solderable for securement of power lines thereto. Such a bus tape possesses both in plane and through plane conductive characteristics and can easily be cut to any length desired for the mirror sizes being produced.

The integrated circuit module comprises an integrated circuit "chip" mounted in opposing relationship to a carrier substrate and having a plurality of interconnects, such as solder bumps or wire interconnects, for providing signal lines and supplying power to the chip. Some of the interconnects are, instead, used to form capacitors such that bypass capitance is placed in close proximity to the chip, while not using up valuable real estate on the chip or on the carrier substrate. Various embodiments of such bypass capacitors are shown.

Abstract: An improved connection through a substrate layer is formed by embedding a conductive element such as a pin on one or more balls or spheres in a thermoplastic material which is preferably a liquid crystal polymer. The substrate may be heated to facilitate the embedding process in which material of the substrate layer is reflowed under pressure to retain the conductive element by means of a preload force. The formation of such connections with either pins or plural conductive elements allows independence of aspect ratio of the connection and, hence, feature size of conductive patterns on the substrate and the thickness of the substrate layer.
