    摘要: Techniques are disclosed that allow for the use of metal halide lamps in dimming applications, as well as other discharge lamps susceptible to dimming-induced chromaticity drift. Examination of such lamps reveals that some of the spectral changes that cause chromaticity drift during dimming are localized in narrow band regions of the spectrum, and lamp emission in these regions is enhanced (either increased or decreased) relative to the rest of the spectrum. Selective filtering of the enhanced emission caused by dimming can be used to reduce chromaticity shift. For instance, a filter deposited on and/or integrated into a lamp component (such as the arc tube, shroud, and/or outer jacket) operates to block transmission of those regions of the spectrum.

    摘要: When aging is performed by applying aging voltage to a data electrode, a scan electrode, and a sustain electrode via respective inductors (301, 401, 302, 402, 303, 403) coupled to the electrodes, frequency of a ringing waveform included in an aging voltage waveform applied to the data electrode is set in a range of ½ to 2 times frequency of a ringing waveform included in an aging voltage waveform applied to the scan electrode. With the method above, the time required for aging is significantly shortened, and the aging with high efficiency in electric power is realized. Instead of using inductors (301, 302, 303) including a coil, controlling the length of lead wires (401, 402, 403) can also obtain desired inductance.

    摘要: In an electron source manufacturing method and apparatus, a plurality of electron-emitting devices are commonly connected to a first wiring and to a plurality of second wirings, respectively. A voltage V1 is applied to the plurality of devices connected to the first wiring by the difference between potentials applied to the first wiring and the plurality of second wirings. The voltage V1 has a relationship with a maximum value V2 of a voltage applied as a normal driving voltage after the voltage application step, so as to satisfy: giving a current I flowing upon application of the voltage V when a voltage V falling within a voltage range causing electron emission upon application of the voltage between the two electrodes of each device is applied to the device: I=f(V)  (1) and letting f′(V) be the differential coefficient of f(V) at the voltage V, a condition: f(V1)/{V1·f′(V1)−2f(V1)}>f(V2)/{V2·f′(V2)−2f(V2)}  (2) In this manner, the potential applied to each second wiring is set to reduce the difference in magnitude of the voltage V1 applied to each device connected to the first wiring.

    摘要: The adjustment apparatus automatically adjusts the position and angle of a deflection yoke attached to the neck part of a cathode ray tube. A cathode ray tube having a deflection yoke as an adjustment target attached to its neck part is fixed to a predetermined adjustment position such that its tube axis extends in the horizontal direction. The adjustment apparatus holds a deflection yoke attached to the neck part of the cathode ray tube fixed to an adjustment position by means of a hold mechanism. A test image displayed through a fluorescent surface of the cathode ray tube is picked up by a plurality of cameras. The deflection yoke held by the hold mechanism is moved based on image data picked up by the cameras. The position and angle of the deflection yoke with respect to the neck part are automatically adjusted.

    摘要: An improved low power pulsed anode magnetron is provided having a cylindrical cathode centrally disposed within a plurality of radial anode vanes. An interaction region is provided between the surface of the cathode and the anode vane tips. A ratio of the anode-to-cathode space over the center-to-center distance between adjacent vane tips is within a range between 0.95 and 1.05. The cathode is joined to a magnetic polepiece assembly which channels magnetic flux to the interaction region. Both the cathode and the polepiece are mechanically adjustable from external to the magnetron to reposition the cathode and polepiece with respect to the anode vanes. The cathode surface is formed from an active nickel alloy which is cleaned by a chemical process followed by a high temperature and vacuum firing. An emissive surface is applied over the cleaned cathode surface. The output spectrum of the magnetron is calibrated by applying a sequential pulsed input of increasing amplitude, and adjusting the relative cathode-anode position until the frequency spectrum remains constant.

    摘要: An image registration system for registering multiple images on a screen is disclosed. A single registration sensor, such as a photodetector, is disposed at an image plane of the system, typically adjacent an edge of the image plane of an image whose position is to be controlled and registered. A sensor mask having a square opening is disposed adjacent the photodetector, and between the image projector and the photodetector. A calibration light pattern is generated, illuminating the entire active area of the photodetector during a calibration time interval. The photodetector output is saved as a calibration value. A vertical test pattern is generated nominally illuminating only one vertical half of the sensor active area, and the sensor output is saved as a vertical pattern value. A horizontal test pattern is generated, nominally illuminating only one horizontal half of the sensor active area, and the sensor output is saved as a horizontal pattern value. The calibration, vertical pattern and horizontal pattern signals are then processed to provide image position correction signals.

    摘要: A method of and a device for use in manufacturing a color display tube in which magnetic poles are provided in or around the neck (4) of the tube envelope (1) and around the paths of the electron beams (18, 19, 20) extending substantially parallel to the axis (8) of the tube, said magnetic poles generating a permanent multipole magnetic field for the correction of the convergence, color purity and frame defects of the color display tube. The magnetic poles are formed by magnetization of a configuration of a magnetizable material (15) which is provided around the paths of the electron beams (18, 19, 20), said configuration being magnetized by energizing a multipole coil unit (21-28) by means of a combination of currents (Ia-Ih) which generate a static multipole magnetic field and the magnetization is produced by means of a decaying alternating magnetic field which initially drives the magnetizable material on both sides of the hysteresis curve into saturation. If the magnetization takes place within one frame period and the decaying alternating magnetic field has a frequency between 400 Hz and 4000 Hz, in which the decrease of the amplitude of the alternating magnetic field is less than 10% per half a cycle, an inexpensive and rapid method of magnetization is achieved in which it is not necessary to switch off the voltages at the gun electrodes (5, 6, 7) and the currents through the deflection coils (13) during magnetization.

    摘要: An improved method and apparatus for rapidly and accurately adjusting CRT image geometry for the purpose of removing defects in an image reproduced by a CRT. The method and apparatus include a conventional pattern generator for producing a grid-like test pattern, in the form of two mutually perpendicular sets of closely spaced parallel lines, on the viewing screen of the CRT whose geometry or image-forming apparatus is to be adjusted. A reference pattern image formed on a transparent base material suitable for viewing by transmitted light and having the same general characteristics as the CRT formed image is supported in superposed relationship with respect to the CRT formed, pattern generator produced test pattern image. Moire pattern bands or fringes indicative of defects in the displayed test pattern and therefore in the CRT geometry viewable by an equipment operator when viewing the displayed test pattern through the transparent reference pattern in such a superposed relationship may be readily removed by adjusting various component parts of the image-forming electron beam deflection system until the moire fringes resulting from image-defect generated misalignment between the CRT formed test pattern image and the transparent material formed reference pattern image are nulled or are no longer visible to an equipment operator.
