  • Patent number: 5583668
    Abstract: A technique for fixedly positioning a holographic recording laminate relative to a master hologram including the steps of inducing a electrostatic charge on the holographic recording laminate and positioning the recording laminate in close proximity to the master hologram such that the electrostatic charge on the recording laminate causes a static attraction between the recording laminate and the master hologram that retains the recording laminate in a fixed position relative to the master hologram.

  • Patent number: 5318820
    Abstract: An elongated composite tape structure including an elongated carrier, and a plurality of sinterable, thermally fusible tape strips of different characteristics disposed on the elongated carrier. Also disclosed is a reel-to-reel process wherein the composite tape structure as stored on a reel is incrementally processed by longitudinally feeding the tape structure through one or more processing stations at each of which the tape is driven in an indexed manner so that predetermined portions of the tape are processed at each station for substantially the length of the tape structure.

  • Patent number: 5164699
    Abstract: Via resistor structures in a hybrid multilayer circuit having a plurality of insulating layers. One via resistor structure includes a plurality of resistive via fills in vias in respective adjacent insulating layers, a plurality of conductive elements for electrically contacting predetermined tops and bottoms of the resistive via fills, and conductive via fills for providing external electrical connection to selected ones of the conductive elements at locations on the outside the unitized multilayer circuit structure. A further via resistor structure includes a resistive via fill formed in a via in one of the insulating layers, and one or more thermally conductive via fills for thermally conducting heat from said resistive via fill to the outside of the unitized multilayer circuit structure.
