摘要： Farbfernsehgeräte oder Farbmonitore können zur Verbesserung der Bildqualität des wiederzugebenden Eingangsvideosignals eine Farbbildröhre mit einer SVM-Spule aufweisen, die die Horizontalablenkung je nach Bildinhalt beschleunigt oder verzögert. Zur Verbesserung der Wirkung der Scan-Velocity-Modulation bei hohen Frequenzen wird vorzugsweise die Elektrode des Elekronenstrahlzeugungssystems, die sich im Bereich der zusätzlichen SVM-Spule befindet, mit schlitzförmigen Öffnungen (10) versehen. Diese Öffnungen sind ein einer Ebene angeordnet, die senkrecht auf der Bewegungsrichtung der Elektronen in den Elektronenstrahlen steht. Vorteilhafterweise wird ein Segment der Fokussierungselektrode mit den schlitzförmigen Öffnungen versehen.

摘要： Es ist bekannt, neben den Ablenkspulen (35, 36) für die Horizontal- und Vertikalrichtung eine zusätzliche Hilfsablenkspule (42 - 45) wesentlich geringerer Induktivität für einen zusätzlichen höherfrequenten Ablenkstrom vorzusehen, z.B. für eine Modulation der horizontalen Ablenkgeschwindigkeit zum Zwecke der Schärfeverbesserung. Aufgabe ist es, eine kostengünstige und einfache Befestigung für eine derartige Hilfsablenkspule zu schaffen, wobei die magnetische Kopplung zwischen der Hilfsablenkspule und der Zeilenablenkspule möglichst klein bleiben soll.
Diese Aufgabe wird dadurch gelöst, daß ein zur Arretierung der Ablenkeinheit auf dem Röhrenhals (33) dienender Klemmring (40) als Träger für die Hilfsablenkspule (42 - 45) ausgenutzt ist. Der Klemmring besteht aus einem nicht metallischem Material.
Die erfindungsgemäße Anordnung ist besonders für Fernsehempfänger mit BSVM (beam scan velocity modulation) geeignet.

摘要： A color cathode ray tube equipped with an electron gun having a main lens of a large equivalent aperture by suppressing the spherical aberration and the astigmatism of the main lens sufficiently. The main lens for converging the three electron beams, which are arranged generally in parallel in one direction toward the fluorescent face, upon the fluorescent face, includes two electrodes arranged to confront each other with such flattened apertures that the diameter H taken in the one direction is larger than a diameter V taken perpendicularly to the one direction. The orbits of the two side ones of the three electron beams passing through the main lens have a constant gap S from the orbit of the center electron beam. The relations of H = 2(S + R) and R > S hold, if the distance between the orbits of the two side electron beams and the inner circumference, as taken in the one direction, of the electrodes constituting the main lens is designated at R.

摘要： A convergence unit for an in-line colour cathode ray tube consists of 4 E-cores (5) located around the neck (1) of the CRT. Each E-core, preferably consisting of strip-shaped soft-magnetic material such as mumetal or permalloy, carries two coils (7, 8) connected so that the net magnetic field at the central beam (3) is zero. The E-cores (5) are arranged in pairs with the resultant fields at the nearer electron beam due to each individual E-core being substantially orthogonal to one another.

摘要： An improved lateral convergence deflection system for a delta-gun shadow mask color CRT (10) includes first, second and third lateral convergence coils (20, 22, 24) mounted on the CRT neck (10) radially outward from the paths of the electron beams (14,16,18) from the three guns. The coils are connected in series electrically, and are of suitable strength and orientation to provide a substantially unidirectional, vertical field in the path of one (e.g., the blue) beam (14), and field nulls in the paths of the other two (e.g. the red and green) beams (16,18). By varying the current passed through the coils by a convergence drive amplifier, the blue beam may be shifted laterally without producing any substantial movement of the other two beams.

摘要： A cathode-ray tube comprising an electron gun (4) disposed in the neck portion (3) of a funnel (2), a deflection yoke (5) having a horizontal deflection coil (51) and a vertical deflection coil (52) mounted on the outer surface of the funnel (2) in a position closer to the front panel than the electron gun (4), and a speed modulation coil (6) mounted on the outer surface of the neck portion (3). The speed modulation coil (6) is so disposed that the end part thereof on the front panel side is closer to the electron gun (4) than the end part of the horizontal deflection coil (51) facing the electron gun (4) and closer to the front panel side the end part of the electron gun (4) facing the front panel. A desired speed modulation effect can be attained because the speed modulation magnetic field (28) of the speed modulation coil (6) does not interfere withe the deflection magnetic field and can be prevented from disappearing by causing by causing an eddy current in a top unit (27).

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.
