摘要： A parabola modulation circuit performs amplitude modulation of a horizontal parabola signal by a vertical modulation signal by multiplying the horizontal parabola signal and the vertical modulation and the phase of the parabola signal is modulated in accordance with the vertical modulation signal. The modulated horizontal parabola signal is output to a correction current output amplifier. When an NS pin-cushion distortion on the CRT tube is right-left asymmetric, a horizontal parabola signal generation circuit is set, so as to generate a right-left asymmetric horizontal parabola signal. By adjusting the value of n in the n power waveform generator in the horizontal parabola signal generation circuit, it is possible to correct the gull wing distortion.

摘要： A video display (10) includes a scanner (100) operable at a first frequency (H1) and a higher second frequency (H2). A switchmode power supply (SMPS) (32) drives a transformer (T1) with three secondaries (T1S1b, T1S1a and T1S2). First and second rectifiers & filters ((CR107, CR108) and (F101, F102)) are associated with the first and second secondaries. A rectifier is coupled to the third secondary (T1S1b) and by way of a switch (K2) to the first filter (F101). Feedback from the first filter (F101) controls the SMPS (32). In a first operating mode, the scanner (100) is operated at the first frequency, the switch is open, the scanner supply (SCAN +) is a first voltage from the first filter (F101), and ancillary equipment is supplied with a third voltage by the second filter (F102). In a second operating mode, the scanner (100) is operated at the second frequency, the switch (K2) is closed, the scanner supply (SCANB +) is a second voltage, higher than the first, from the first filter (F101), and ancillary equipment is supplied with the same third voltage.

摘要： A cathode head (200) is provide that is suitable for use in an x-ray device (100) that includes an anode (300) having a target surface (304) configured and arranged to receive electrons emitted by the cathode head (200). The cathode head (200) may be constructed of magnetic or non-magnetic material and includes an emitter structure (202) carrying a filament (204) that defines a longitudinal axis about which is disposed one or more magnetic elements such as coils (208). The filament (204) is configured and arranged to emit an electron beam that defines a focal spot on the target surface (304) of the anode (300). The magnetic coil, or coils (208), disposed about the longitudinal axis defined by the filament (204) generate a magnetic field that enables control of the location of the focal spot on the target surface of the anode.

摘要： A cathode ray tube (CRT) (1) having a glass envelope (2) is disclosed. The glass envelope is formed of a rectangular faceplate panel (3) and a tubular neck (4) connected thereto by a funnel (5). An electron gun (13) is positioned in the neck for directing electron beams toward the faceplate panel. A yoke (14) is positioned in the neighborhood of the funnel-to-neck junction. The yoke has windings configured to apply a horizontal deflection yoke field and a vertical deflection yoke field to the beams. At least one magnetic field sensor (17) is located near the glass envelope for sensing an ambient magnetic field environment of the CRT. A controller receives a signal from the magnetic field sensor. Register correction coils are mounted in the vicinity of the neck and are dynamically controlled by the controller to shift the beams. Quadrupole coils (16) are applied to the neck and have adjacent poles of alternating polarity such that the resultant magnetic field being dynamically controlled by the controller based on the magnetic field sensor signal moves outer ones of the beams to correct the misconvergence caused by the register correction.

摘要： In a color CRT apparatus in which three electron beams 4, 5, 6 are not superimposed on one point on the screen 11 at a time, a time difference is applied to modulating signals 12, 13, 14 corresponding to the respective electron beams to adjust phase, thus achieving convergence of images, the screen is flat, both a horizontal magnetic deflection field and a vertical magnetic deflection field have uniform magnetic field distribution, paths of both side electron beams and a path of the center electron beam of the three electron beams 4, 5, 6 emitted from electron sources 1, 2, 3 are approximately parallel, and the time difference applied to the modulating signals is set to be approximately constant throughout the screen 11. Thus, images formed of imaging spots of the three electron beams can be superimposed on the screen with high precision to be matched without causing increased cost. Consequently, it is possible to cope sufficiently with the increased display density of image information and increased deflection angle due to the reduction in depth of the color CRT apparatus.

摘要： A bar-shaped element (4) includes magnets (6) at both ends and a magnetic material (5) connecting the magnets (6) to each other. One end in a major axis direction of the bar-shaped element (4) is an N-pole, and the other end is an S-pole. A pair of bar-shaped elements (4) sandwich a deflection yoke in a horizontal direction, with the major axis direction thereof being parallel to a vertical direction, and each of the bar-shaped elements (4) is placed at a position between the end of a horizontal deflection coil (1) on a phosphor screen side and a central position of a core (3) in a tube axis direction, in such a manner that the magnetic poles at both ends are opposite to each other between the pair of bar-shaped elements (4). Because of this, PQH misconvergence is corrected without influencing power consumption at low cost by a simple method without using an auxiliary coil and a correction circuit, whereby satisfactory convergence can be realized.
