  • Patent number: 5929510
    Abstract: An electronic integrated circuit which includes at least one of RF, microwave, digital and analog components connected in a desired circuit. The integrated circuit includes a substrate of a conductive material having on a surface thereof a body of a dielectric material. The dielectric body is formed of a plurality of layers of the dielectric material bonded together. A plurality of strips of a conductive material are on the surfaces of the layers of the body to form RF, analog and digital components. Discrete electronic devices are mounted on the body and connected in the circuit. Vias of a conductive material extend through the various layers of the body to electrically connect the various strips of conductive material on the layers of the body.

  • Patent number: 5925203
    Abstract: A plasma display includes a front panel having a glass body secured to a surface of a substrate. The glass body has a plurality of channels in the exposed surface thereof with upstanding ribs being between the channels. Conductive first electrodes are on the body with each electrode extending along the bottom of a separate channel. The first electrodes are preferably embedded in the glass body. A transparent front panel is over the back panel and is seated on and secured to the glass body. A plurality of spaced, parallel second electrodes extend between the front panel and the back panel substantially orthogonally to the first electrodes. Phosphors which emit different colors are coated on the channels and the channels are filled with a plasma gas.The back panel is formed of at least one and preferably a plurality of layers of a green tape of glass particles in a binder. The layers are stacked one on top of each other and the channels are formed in the surface of one of the layers.

  • Patent number: 5725808
    Abstract: A ceramic mixture of a crystallizable ZnO--MgO--B.sub.2 O.sub.3 --SiO.sub.2 glass mixed with a non-crystallizing lead-based glass and one or more oxide fillers forms a fired ceramic that has a TCE compatible with that of kovar. Green tapes made from the ceramic mixture aligned with a kovar support substrate when fired have excellent dielectric and low loss properties.
