Abstract

PURPOSE:To vary the magnetic field distribution by combining at least two coils each of which is not symmetrical relative to its axis to make a deflection coil anc connecting it to a mechanism for controlling the deflection current of the cois. CONSTITUTION:An upper deflection york 1 is constituted of a first horizontal coil 11 consisting of a sparsely wound section 11A located in the left of axial line (x-y) and a densely wound section 11B located in the right of axial line (x-y), a second horizontal coil 12 consisting of a left densely-wound section 12A and a right sparsely-wound section 12B and a vertical deflection coil 13 the center of which is located on axial line (x-y). Thus, the whole body of the upper deflection york 1 is symmetrical relative to axial line (x-y). A lower deflection york 2 has the same structure as the upper deflection york 1. The distribution of the horizontal deflection magnetic field can be varied by varying the inductances of variable inductance coils 31 and 32, constituting a current control mechanism, by moving movable cores 31A and 32A.

This invention relates to a deflection yoke that can change the magnetic field to a magnetic field asymmetrical with respect to the axis.

バージェンス金得るようになされている。Generally, in color television receivers using in-line picture tubes or delta-type picture tubes, images are obtained using red, green, and blue electron guns. At this time, each electron beam is focused on the picture plane. In order to achieve this, a deflection yoke is provided at the neck portion of the cathode ray tube, and the horizontal deflection magnetic field and vertical deflection magnetic field by the deflection yoke are all set appropriately to obtain an optimum convergence value.

満足のいくものはなかつた。However, the deflection yoke consists of a horizontal deflection coil, a vertical deflection coil, and a core, so even if there are manufacturing variations in the windings a, fjr, and once assembled, it is easy to adjust them. On the other hand, once a cathode ray tube has been manufactured, it is difficult to adjust even if there are manufacturing variations. In order to adjust for manufacturing variations in deflection yokes and Yinya ray tubes,
The adjustment range using magnetic pieces or adjustment screws has a narrow adjustment range and less freedom, so it is not possible to make sufficient corrections, and the accuracy is not satisfactory.

There was a problem that there was a lot of work that had to be done, and that there were so-called design gaps.

Ｋある。The present invention has been developed in view of the problems of the prior art described above, and even if the deflection yoke is raised once after winding, it can be leveled by simply adjusting the current adjustment means that adjusts the entire deflection current. In order to continuously and accurately adjust the magnetic field distribution of the magnetic field or vertical magnetic field, ■ expand the degree of freedom of the coil distribution, thereby achieving the high level of convergence that will be required in the future due to the high precision of displays. We offer a complete range of deflection yokes that can be adapted to suit various applications.

も有効である等積々の効果を発揮することができる。The deflection yoke according to the present invention is as described in detail above, and it is possible to change the magnetic field distribution generated by the horizontal deflection coil or the vertical deflection coil to a desired magnetic field distribution only by adjusting the deflection current by the current adjustment mechanism. Because of this structure, fine adjustments such as color shifts due to manufacturing variations in deflection yokes and cathode ray tubes can be corrected very easily, and the degree of freedom in magnetic field distribution is increased, resulting in high quality and high precision. A f@ image quality can be obtained, paving the way for the realization of a -dimensional deflection yoke, and it can also exhibit a number of effects such as being effective as a deflection yoke for projection televisions.
