Abstract: A transceiver circuit for use in a high speed data transmission network is disclosed that provides for simultaneous bidirectional transmission of data over coaxial or twisted pair media. A transmitter circuit provides an output data signal to a bridge network. The bridge network develops a cancelling signal and a combined signal. A receiver section includes a high speed subtracting circuit that determines the difference between the cancelling signal and the combined signal to effectively cancel data supplied by the transmitter section.

Abstract: An electrostatographic toner fusing member having a support and a layer containing a crosslinked polyfluorophosphazene elastomer with thermally conductive filler particles. This fusing member is used in a device for fusing electrostatographic toner materials to a substrate which device employs both heat and pressure The fusing member exhibits an excellent combination of properties, including resistance to swelling by release liquids, resistance to thermal degradation and thermal conductivity that is superior to prior art fusing members employing crosslinked fluoroelastomers.

Abstract: A curable composition which comprises a homogeneous blend of (a) a solvent soluble polyimidesiloxane containing about 0.2-30 weight percent silicon and (b) an ethylenically unsaturated multifunctional monomer. The siloxane units in the polyimide-siloxane have from 10 to about 200 ##STR1## linkages per unit, more preferably from about 15 to about 100 linkages, and most preferably from about 40 to about 60 ##STR2## linkages per siloxane unit. Another embodiment provides the composition produced by curing the above-described composition. The curable compositions of this invention can be cured by either actinic radiation, e.g., uv light, or thermal radiation. In the cured composition, the polymer produced upon polymerization of the monomer, and the polyimide portion of the polyimide-siloxane form a homogeneous blend, in which the siloxane portion of the polyimide-siloxane is phase separated.

Abstract: A laminate, adapted for manufacturing frames of metal beam leads that are bonded to integrated circuit chips comprising:(a) a flexible metal strip(b) a layer of a first resist adhered to one surface of the metal strip, and(c) a layer of a second resist adhered to the opposite surface of the metal strip, wherein the second resist is a negative-working resist which forms a semi-interpenetrating polymer network-II upon curing and comprises a homogeneous blend.(A) a solvent soluble polyimide-siloxane containing about 0.5-30 weight percent silicon and (B) an ethylenically unsaturated multifunctional monomer. The siloxane units in the polyimide-siloxane have from 10 to about 200 ##STR1## linkages per unit, more preferably from about 15 to about 100 linkages, and most preferably from about 40 to about 100 linkages per siloxane unit. A second embodiment of the invention comprises a metal strip having one side thereof, a composition obtained by curing the above-identified curable composition.

Abstract: An image rotation compensation circuit for use with a CRT. The compensation circuit includes a winding which encircles the CRT and is oriented transverse to the path of the electron beam. A controller is connected to the winding and drives a current through the winding to create a magnetic field. The direction and magnitude of the current may be adjusted by the user to substantially cancel an external magnetic field and thus eliminate any image rotation caused thereby.

Abstract: A horizontal deflection circuit for controlling the horizontal deflection of an electron beam in a cathode ray tube used, for example, in a video display. The circuit uses a plurality of MOSFET transistors, which are switched on and off in unison for switching between a scan mode and a retrace mode, the MOSFET transistors being cascaded to accommodate the high voltage levels which are developed during retrace. A retrace capacitor and retrace diode are connected between the source and drain terminals of each MOSFET transistor to ensure that the voltages are divided among the transistors so that the entire voltage does not appear across any single one if they do not all switch at precisely the same time.
