Abstract: An electron bombarded semiconductor amplifier including an elongated envelope having an electron gun projecting a sheet electron beam towards a distributed element semiconductor target which propagates an output signal including a single extended area semiconductor diode or a plurality of series-connected semiconductor diodes which are reverse biased and a doubly-distributed deflection means adapted to receive an input signal and cooperate with said sheet electron beam to deflect the beam in accordance with an input signal in synchronism with electron beam velocity and target signal propagation velocity to strike the target and generate an amplifier output signal.

Abstract: An electron beam deflection structure for a high frequency cathode-ray tube incorporates a meanderline slow wave circuit that is supported directly by the same glass rods used to support other portions of the CRT's beam forming and deflection system. To accomplish this, elongate loops that serially interconnect a plurality of deflection plate segments are bent away from the plane of the segments (and the beam axis) and joined by integral support strips to the rods. The elimination of a separate support structure for the deflectors greatly reduces manufacturing costs.

Abstract: A system for inputting data into a display device by touch-sensitive contact areas disposed adjacent the display device and including state of the art electronic recognition circuitry associated with the contact areas for synchronously converting the data to discrete elements of information. Specifically, the transparent contact pads are overlayed over a display with each pad coupled with a multiplexer followed by a synchronous quadrature filter function performed by yet another multiplexer in such a manner that data displayed may be altered.

Abstract: A laminar flow electron gun employing a narrow, elongated cathode for forming a rectangular beam and a plurality of electrodes having narrow, elongated apertures cooperating with said cathode to draw electrons from said cathode and operate on the electrons to focus the rectangular beam onto a target by providing a parallel flow region adjacent said cathode, followed by a divergent flow region, in turn, followed by a convergent flow or focusing region.
