Abstract:
An FED, modified with an electrostatically deformable anode, has a control network attached to electrodes thereof to switch the FED off as the anode is deformed by electrostatic force and switch the FED on as the anode returns to a quiescent state. Frequency selectivity is realized by incorporating a variable frequency determining network within the control network.
Abstract:
The integrated circuit described is a function generator which, for example, is eminently suited for use in a shutter system of an automatic photographic camera. The current which is delivered by the photodiode and is a measure of the intensity of the light incident on the objective of the camera is supplied to this function generator as the input current. This current is converted, by means of a voltage which is generated in the generator and is a function of the film speed of the film used and the diaphragm stop, into an output current which is supplied to an integrating circuit. The value of the said output current and the integrating circuit then determine the exposure time.

Each of the plurality of pixel units includes a first electrode located on the insulating substrate; a plurality of first electron emitters located on and electrically connected to the first electrode; a first phosphor layer located on the first electrode; a second electrode located on the insulating substrate and spaced from the first electrode, wherein the second electrode extends at least partly around the first electrode; a plurality of second electron emitters located on and electrically connected to the second electrode; and a second phosphor layer located on the second electrode.
Abstract:
A flat panel display reduces the line resistance of a driving power supply line and prevents a voltage drop in the driving power supply line so as to obtain uniform resolution and luminance. The flat panel display includes a substrate, a display region formed on the substrate, the display region having a self-luminescent element and VDD lines that supply a driving potential power and/or a source current to the self-luminescent element. Further, a covering member for sealing the display region at least, the covering member being adhered to the substrate to face the substrate and a terminal region formed on one or more edges of the substrate, the terminal region having one or more driving power terminals are provided. In addition, a driving power supply line that connects the driving power terminals to the VDD lines of the display region and a bus conductive unit that is electrically connected to the driving power supply line are provided.

Abstract:
An improved electron multiplier assembly includes a plurality of communicating electrodes affixed to a pair of insulative support plates. The electrodes comprise a plurality of dynodes including an ultimate dynode and an anode. The anode comprises a substantially flat, rigid member having at least one longitudinally-extending aperture. The anode is disposed substantially within and spaced from the ultimate dynode. Mounting tabs extend from the anode to inflexibly secure the anode to the support plates.
Abstract:
The electrode is circular in configuration, with a central opening, so that it has inner and outer rims. The electrode structure comprises a plurality of spiral-shaped vanes of conducting material which are separated by relatively thin slit-like openings. The spiral vanes begin at an inner boundary which is close to the inner rim of the electrode and rotate approximately one-half turn to the outer rim of the electrode. A portion of the electron beam, which is typically produced from a cathode energized by a high voltage source, strikes the electrode near the central opening, and travels along the vanes of the electrode to ground, thereby establishing a plurality of spiral current paths in the electrode. These spiral currents create a magnetic field about the center of the anode in the region of the electron beam, focusing the remainder of electron beam through the opening in the electrode.
Abstract:
An anode assembly for a luminescent display tube comprises a substrate and a plurality of anode segments. The anode segments have layers of a luminescent material deposited in respective recesses formed in the substrate in conformity with the anode segments. A layer of tungsten carbide is disposed underlying each of the luminescent material layers.
