    Abstract: An encapsulated planar cathode structure is formed for a vacuum tube. A multibeam cathode ray tube is obtained by heating in the CRT such a structure with a plurality of separated electron emissive layers to remove the encapsulation material. Positive photoresist technology is utilized: for obtaining delineated apertures on a planar metallization layer supported by an insulating substrate into which needle-shaped carbonate particles are deposited electrophoretically normal to the metallization; and for encapsulating the resultant cathodes.

    Abstract: An apparatus for heating the cathode of an electronic power tube, having a supply for delivering a heating current to the cathode, an interrupter circuit for periodically interrupting the flow of heating current to the cathode, and controls for controlling the duration of these periodic interruptions and for regulating the net amount of heating current. To achieve this, the controls include a voltage control that varies in such a way so as to bring the heating current from a value of O to Io (where Io is the correct heating current at which the tube will be in a pre-heated condition) during a first, predetermined time period, and then from a current Io to a current Im (where Im is the optimum value for the heating current when the tube is normally operating), during a second predetermined time period.

    Abstract: An improved diode for forming an intense electron beam and propagating theeam. The diode includes a cathode having a bore, and a rod-shaped anode having a medial tapered section which extends, approximately coaxially, through the bore of the cathode. The anode tapers at or near the cathode and is formed from electrically conductive material. The cathode is made from a material which rapidly emits electrons during the early stage of an applied voltage pulse. The electrons strike the anode and form a plasma thereon. Sufficient anode current and the formation of sufficient anode plasma affect the magnetic and electric fields to pinch the electrons closer to each other and to force the electron beam to propagate along the anode and away from the cathode and voltage supply. The tapered section of the anode increases the velocity of the pinch and the density of the electron beam.

    Abstract: A series of discrete heating current pulses are passed through a line cathode so as to cause the cathode to emit electrons therefrom. Between each consecutive pair of pulses is a cooling period during which no heating current flows through the cathode. Current is extracted from the cathode during this cooling period. In a preferred embodiment for an image display device, the heating pulse duration is about 10 .mu.sec and the cooling period is about 50.mu.sec. In this scheme, the heating period corresponds roughly to the horizontal retrace time between line times of 50.mu.sec.

    Abstract: A technique of reducing the radiation sensitive nature of both P-channel and N-channel components of a CMOS structure. The channel oxide in both components is grown as pure as possible during the manufacture with a special attempt to keep the alkali content low. After the manufacturing process is complete, the Pchannel component is masked while the entire N-channel component is subjected to an ion implantation which radiation hardens the entire CMOS device or circuit. This process provides a CMOS device which maintains a useable threshold level in the presence of and after it has been exposed to 106 rad of radiation.

    Abstract: The power regulator includes a pass transistor connected between a first supply providing a first unregulated pulsating d.c. voltage and load whose resistance is initially low, but rises to a higher value as power is supplied thereto. An amplifying transistor controls the current flow through the pass transistor and load. A zener diode limits the amplitude of the load voltage. A second supply provides a control voltage to the amplifying transistor which regulates the output power by shaping the output voltage waveform. A starting circuit, connected between a power supply, the load and the amplifying transistor, initially supplies starting current for the regulator. The starting circuit is turned off by the increasing voltage developed across the load as power is delivered thereto.
