    摘要: A ferromagnetic shielding funnel having a flange at its wider end for reception within the conical portion of a cathode ray tube, the funnel having support members at the corner portions of its flange. Each support member has a base plate which is attached to the flange and a distal end which has been bent into a V-shape for bearing on a respective pin in the wall of the cathode ray tube. For preventing that the funnel comes loose from the pins, the support members comprise further attachment means with which they are attached to a skirt of the flange. Preferably, the base plate is attached to the flange by means of two first connections to a flange portion which is parallel to a long side of the cone portion and two second connections to a flange portion which is parallel to a short side of the cone portion. The extreme ones of these connections are preferably arranged such that bending of the flange at the corner portions is prevented.

    摘要: A color display tube (1) is disclosed with an improved suspension of the color selection electrode (12). In order to have a color display tube with good properties of, for instance, color purity, it is of eminent importance that the color selection electrode (12) has and excellent positional stability. Especially wide screen tubes seem to be more sensitive to external shocks by which the color selection electrode (12) may shift and cause discolorations. The positional stability of the color selection electrode (12) can be improved by decreasing the friction between the color selection electrode (12) and the supporting elements (17) in the display window (3) of the color display tube (1). This is achieved by applying a supporting element (17) with a free end portion (22) having a small diameter and by applying a low force between the suspension means (20) and the supporting elements (17). As a consequence of the lightweight construction of the color selection electrode (12), this force can be lowered to about 4 newtons.

    摘要: In the manufacturing process of a color display tube (1), the display window (3) is assembled with the funnel shaped part (4) in a furnace by subjecting them to a heat treatment. This heat treatment can lead to deformation of the color selection electrode (12), because in color display tubes (1) with an invar shadow mask (13), the diaphragm parts (15) are made from invar as well, while the corner sections (16) are made from iron in order to obtain enough stiffness. The difference in expansion coefficient between invar and iron leads to shearing of the welds (22) that connect the diaphragm parts (15) to the corner section (16). To overcome this problem the invention proposes to provide the diaphragm parts (15) with slits (23) or impressions (24), which are arranged so that no stress occurs between the spot welds (22) when the color selection electrode (12) is heated.

This can be realized by introducing an additional support plate (41) in the corner section (16). Also the optimization of the position of the supporting element (17) with respect to this corner section (16) yields an improvement.

    摘要: A color selection electrode is suspended in a color display tube from pins which are provided in the corners of the display window. The suspension means comprise a resilient element which is secured to the color selection electrode, and a slide plate slidably secured relative to the flat resilient element rigidly secured to the pin. During the suspension the position of the color selection electrode is adjusted, and the slide plate is rigidly secured to the resilient element.

    摘要: A color cathode ray tube comprises a color selection electrode which is secured to a frame and a magnetic screening cap. The frame has two diaphragm portions one of which is located near the color selection electrode and the other is further removed from the color selection electrode. The distance between the electron beams deflected towards the outermost apertures of the color selection electrode and the further removed diaphragm is at least 1 cm. By virtue thereof, the negative influence of the frame on the screening effect of the magnetic screening cap is substantially reduced.
