  • Patent number: 4537483
    Abstract: An improved optical projection viewing system is provided with a novel wide projection angle relay projection lens and a novel magnifying biocular viewing lens. The magnifying biocular viewing lens has non-symmetric front and rear biconvex surfaces having a uniform field distance when viewing the entire image on the viewing screen. The biocular viewing lens has positive distortion and color separation which is compensated for by negative distortion and color separation provided in the relay projection lens.

  • Patent number: 4446477
    Abstract: A novel thin film processing substrate is embodied into a multichip hybrid module. The processing substrate is provided with conductive vias which are arranged in an area array having the same pattern as the lead out pin vias on a base substrate. The top surface of the processing substrate is built up by thin film techniques to provide a laminate thereon comprising a ground plane and a plurality of thin film X-direction and Y-direction signal distribution lines separated one from the other by thin polyimide insulating layers. The interconnecting thin film lines and polyimide layers are built up as patterns using photolithographic techniques. The X and Y-direction conductive lines and the ground plane are selectively interconnected through the vias and each other to form a predetermined signal distribution circuit.

  • Patent number: 4442425
    Abstract: An electrically passive keyboard is provided with an array of keys. Each key is provided with an actuating bar which when depressed cooperates with a plurality of coded shutters. Each shutter is arranged to intercept a beam of light passing from light projecting elements to light collecting elements. Light pulses generated at a light source are coupled to the projecting elements with fiber optic cables. Decoding logic is coupled to the light collectors with fiber optic cables. Delay elements are provided in series in the fiber optic cables so that the decoding elements receives a plurality of binary coded light signals in a predetermined timed sequence which are converted into binary coded electrical signals at a point remote from the electrically passive keyboard.

  • Patent number: 4248148
    Abstract: A plurality of print hammers are mounted on a horizontally movable carriage and adapted to scan a plurality of column positions of an impact printer. Each print hammer is provided with an energizible electrical coil which moves horizontally with the print hammers in the scan direction. The energizible electric coils on the print hammers cooperate with a fixed magnetic field provided by a pair of fixed bar magnets which extend beyond the distance scanned by the energizible coils on the print hammers.
