摘要： A dynamic bearing with an improved thrust bearing and a beam deflecting apparatus employing the same are disclosed. The dynamic bearing includes a bearing housing having a hollow cavity. A shaft is provided in the hollow cavity so that the shaft can rotate with respect to the bearing housing. First and second magnets are disposed at one end of the shaft and the hollow cavity, respectively. The first and second magnets are spaced a predetermined gap from each other and face each other. The first and second magnets generate a magnetic, repulsive force and support the shaft, without contact, in the axial and radial directions. The dynamic bearing may be used in a beam deflecting apparatus. In that case, a driving source is installed, in parts, on the bearing housing and the rotating shaft. The driving source drives the rotating shaft to rotate by electromagnetic force. A beam deflecting device is installed on the rotating shaft for deflecting an incident beam and performing a scanning operation.

摘要： The screen electrode in an electron gun for use in a cathode ray tube has multi-stage apertures such that the entrance area of an aperture is larger than the exit area. This has an effect of smaller screen electrode apertures with a result of increased pre-focusing of electron beams passing through the apertures. Thus, increased pre-focusing reduces the beam incident angle to the main lens. A smaller beam incident angle generates less spherical aberration in the main lens.
