Die Erfindung betrifft eine Magnetanordnung zur seitlichen Verschiebung des »blauen« Elektronenstrahls einer Mehrstrahl-Farbbildröhre mit einem stabförmigen, drehbar gelagerten Permanentmagneten, dessen Drehachse in einer senkrecht zur Röhrenachse liegenden Ebene verläuft (Blaulateralmagnet).The invention relates to a magnet arrangement for the lateral displacement of the "blue" electron beam a multi-beam color picture tube with a rod-shaped, rotatably mounted permanent magnet, whose axis of rotation runs in a plane perpendicular to the tube axis (blue lateral magnet).
Es ist vorgeschlagen worden, den Permanentmagneten als radial magnetisierten, entlang der Drehachse hintereinander drei Abschnitte, von denen der mittlere Abschnitt zu den äußeren Abschnitten entgegengesetzt magnetisiert ist, aufweisenden Permanentmagneten auszubilden, der im Bereich des mittleren Abschnittes in den Schenkeln einer U-förmigen Halterung gelagert ist, deren Scheitel dem Elektronenstrahl zugewandt ist und deren Schenkel von außen gegen die äußeren Abschnitte des Permanentmagneten drücken.It has been proposed to use the permanent magnet as radially magnetized, along the axis of rotation one behind the other three sections, of which the middle section is opposite to the outer sections is magnetized to form having permanent magnets in the area of the middle Section is mounted in the legs of a U-shaped bracket, the apex of which the electron beam is facing and its legs from the outside against the outer portions of the permanent magnet to press.
Permanentmagnete mit einer solchen abschnittweise unterschiedlichen Magnetisierung sind schwierig herzustellen und teuer. Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu beseitigen.Permanent magnets with such a different magnetization in sections are difficult to manufacture and expensive. The invention is based on the object of eliminating these disadvantages.
Sie besteht darin, daß der Permanentmagnet diametral magnetisiert ist und vorzugsweise in seiner ganzen Länge von zwei Halbzylinderschalen aus paramagnetischem Material umgeben ist, von denen die eine auf halber Länge einen Polschuh, die andere an beiden Enden Polschuhe trägt, die vorzugsweise an ihrem dem Permanentmagneten abgewandten Ende so geformt sind, daß sie sich zumindest angenähert an einen Kreis anlegen.It consists in the permanent magnet being magnetized diametrically and preferably in its the entire length is surrounded by two semicylindrical shells made of paramagnetic material, one of which one of them has a pole piece halfway along the length, the other has pole pieces at both ends, which are preferably are shaped at their end facing away from the permanent magnet that they at least approximate to a circle.
Im folgenden wird die Erfindung an Hand eines Ausführungsbeispieles gemäß den Abbildungen erläutert. The invention is explained below using an exemplary embodiment according to the figures.
F i g. 1 zeigt den stabförmigen Permanentmagneten 1, der in den Knopf 2 eingeklebt ist.F i g. 1 shows the rod-shaped permanent magnet 1 which is glued into the button 2.
Fig. 2 zeigt in verschiedenen Ansichten und Schnitten zwei Halbzylinderschalen 3 und 4 (zusammengesetzt), wobei Teil 3 in der Mitte einen Lappen 5 mit einem Polschuh 6 aufweist, während Teil 4 an den Enden zwei Lappen 7 und 8 mit Polschuhen 9 und 10 aufweist. Alle Polschuhe 6, 9,10 sind so geformt, daß sie sich der Krümmung des Halses der Kathodenstrahlröhre anpassen. Fig. 3 zeigt die Gesamtansicht der Magnetanordnung, wobei die beiden Polschuhe 9,10 mit Nieten 11,12 auf einem Ring 13 aus nichtmagnetischem Material mit Flansch-Schraub-Anordnung 14 befestigt sind.Fig. 2 shows in different views and sections two half-cylinder shells 3 and 4 (assembled), part 3 having a tab 5 with a pole piece 6 in the middle, while part 4 is on has two tabs 7 and 8 with pole pieces 9 and 10 at the ends. All pole shoes 6, 9, 10 are shaped so that that they adapt to the curvature of the neck of the cathode ray tube. Fig. 3 shows the overall view the magnet arrangement, the two pole pieces 9,10 with rivets 11,12 on a ring 13 made of non-magnetic material with flange-screw arrangement 14 are attached.
Zur Einführung einer dynamischen Konvergenz wird der Lappen 5 mit einer Spule 15 versehen, die in bekannter Weise mit parabel- oder sägezahnförmigen Strömen gespeist wird.To introduce dynamic convergence, the flap 5 is provided with a coil 15, which is shown in FIG is fed in a known manner with parabolic or sawtooth-shaped currents.

dung beschrieben. Die diametrale Magnetisierung des Permanentmagneten 1 wird, wenn beispielsweise der eine Pol der einen, der andere Pol der anderen der beiden Halbzylinderschalen 3, 4 zugewandt ist, von diesen durch die Lappen 5 bzw. 7, 8 auf die Polschuhe 6 bzw. 9,10 übertragen, so daß sich die magnetischen Feldlinien zwischen den Polschuhen 6 bzw. 9,10 schließen. Durch Verdrehen des Permanentmagneten 1 mittels Knopf 2 kann die magnetische Feldstärke verändert werden. Die Halbzylinderschalen 3,4 haften durch die magnetische Anziehung fest an dem Permanentmagneten.application described. The diametrical magnetization of the permanent magnet 1 is, for example, when the one pole facing the one, the other pole facing the other of the two semi-cylindrical shells 3, 4, of this transferred through the tabs 5 and 7, 8 to the pole shoes 6 and 9,10, so that the magnetic field lines between the pole pieces 6 and 9,10 close. By turning the permanent magnet 1 with button 2 the magnetic field strength can be changed. The half-cylinder shells 3, 4 adhere firmly to the permanent magnet due to the magnetic attraction.
Es ist auch möglich, die Halbzylinderschalen untereinander durch schmale Stege zu verbinden.It is also possible to connect the half-cylinder shells to one another using narrow webs.
