    摘要: A cathode ray tube device includes: a cathode ray tube with an envelope including a panel having a phosphor screen on its inner face and a funnel having a neck portion including an electron gun; and a deflection unit disposed around an outer face of the funnel. An inductance-adjusting element is provided therein for reducing an inductance at a frequency in an audio frequency band of at least one of a plurality of coils included in the deflection unit, and thereby noise is reduced that is generated by the at least one of the plurality of coils whose inductance is thus reduced.

    摘要: Die erfindung betrifft somit eine Farbbildröhre und ein Ablenksystem für eine Farbildröhre mit einem rechteckigen Leuchtschirm und einem In-Line-Elektronenstrahl-Erzeugungssystem. Ein In-Line-Elektronenstrahl-Erzeugungssystem erzeugt mehrere im wesentlichen in einer gemeinsamen Ebene verlaufende Elektronenstrahlen, die auf den Leuchtschirm gerichtet sind. Um eine Ost-West-Innenkissen-Verzeichnung zu korrigieren, werden auf der Farbbildröhre bzw. im Ablenksystem einer Farbbildröhre in einer ersten Ebene Konvergenzmagnete (8) und in einer zweiten, davon verschiedenen Ebene Geometriemagnete (10) angeordnet. Die Ebene der Konvergenz- und Geometriemagnete sind jeweils senkrecht zur Richtung der Elektronenstrahlen ausgerichtet. Die vorliegende Erfindung ermöglicht damit eine Farbbildröhre, bei der eine herkömmliche Ost-west-Innenkissenverzeichnung ohne eine Schaltung zur zusätzlichen Modulation des horizontalen Ablenkstroms korrigierbar und die trotz verbesserter Abbildungseigenschaften günstig herstellbar ist.

    摘要: A color picture tube device in which a lens is generated in an area through which a plurality of electron beams pass, so as to be positioned, in a tube axis direction, between a phosphor screen and an end of a core nearest the electron gun. The lens has a horizontal focusing effect that focuses each of the electron beams in the horizontal scanning direction. Furthermore, an interval between at least the two outermost of the plurality of electron beams is adjusted, so that the interval at a time of the electron beams entering the lens widens as the degree of horizontal deflection by a horizontal deflection coil increases.

    摘要: A color picture tube device has a funnel glass, a pair of horizontal deflection coils, an insulating frame, and a pair of vertical deflection coils. The pair of horizontal deflection coils are opposed to each other in a vertical direction around the outer surface of the funnel glass, and each have a window at the center. The insulating frame covers the horizontal deflection coils, resembles in shape a part of the funnel glass where the horizontal deflection coils are provided, and has openings in areas corresponding to windows of the horizontal deflection coils. The pair of vertical deflection coils are opposed to each other in a horizontal direction around the outer surface of the insulating frame, without overlapping the openings. In this color picture tube device, a pair of correction coils are provided so as to be each at least partially inserted in a different one of the openings.

    摘要: Deflector for cathode-ray tube comprising a pair of horizontal deflection coils (3) and a pair of vertical deflection coils (4), the two pairs being in the shape of a saddle and isolated one from the other by a separator (2), a frustoconical shaped ferrite ring (5) at least partially covering the deflection coils, the deflector being characterized in that it includes to the rear of the deflection coils, between the horizontal and vertical deflection coils, four field shapers (20) placed symmetrically with respect to the axes of symmetry of the deflector. These shapers are placed so as to increase the amplitude of the second harmonic of the potential of the vertical deflection field without affecting the fundamental of the said potential in order to act on the phenomena of coma appearing on the horizontal edges of the image formed on the tube screen.

    摘要: In a cathode ray tube (10), an electron beam is directed towards a faceplate (20) having an electrode (22) biased at screen potential and is magnetically scanned across the faceplate (20) to impinge upon phosphors (23) thereon to produce light depicting an image. A six-pole coil (15) is disposed proximate the deflection yoke (16) and/or on the tube neck (14) to modify the focus of the red, green and blue electron beams to control focus. An electrode (46) between the tube neck (14) and the faceplate (20) is biased at or above screen potential to deflect electrons over a greater total angle than is obtained from the magnetic deflection.
