    • A color picture tube has a rectangular shadow mask mounted therein in spaced relation to a viewing screen. A major axis passes through the center of the mask and parallels the long sides thereof and a minor axis passes through the center of the mask and parallels the short sides thereof. The mask has an aperture array that includes slit-shaped apertures aligned in columns that essentially parallel the minor axis and end at a border of the aperture array. Adjacent apertures in each column are separated by tie bars in the mask that are longitudinally offset from column to adjacent column. The spacing from tie bar to tie bar in a column is the tie bar pitch at a location on the mask. A first set of the aperture columns, comprising every other column, has full length ultimate apertures at least at one end thereof, and a second set of the aperture columns, comprising every other column not in the first set, has partial length ultimate apertures at least at one end thereof. The ultimate apertures of all of the aperture columns end on smooth curved border lines. The tie bar pitch of the columns decreases from the center of the mask to the short sides thereof, with the tie bar pitch in the region of the short sides of the mask being optimized to minimize moire at the sides of the screen during tube operation. The tie bar pitch along each column varies also from the center of the mask to the long sides of the mask.

    • An improved method of making a color picture tube shadow mask includes first constructing an apertured flat mask which is formed into a domed contoured mask. The mask has a rectangular periphery with two long sides and two short sides. The mask has a major axis, which passes through the center of the mask and parallels the long sides, and a minor axis, which passes through the center of the mask and parallels said short sides. The mask includes slit-shaped apertures aligned in columns that essentially parallel the minor axis. Adjacent apertures in each column are separated by tie bars in the mask, with the spacing between tie bars in a column being the tie bar pitch at a particular location on the mask. The improvement comprises a first step of calculating the desired tie bar shadow locations at several discrete areas, for a given scan line pitch, as viewed from a distance in front of a viewing screen of a tube. The desired tie bar shadow locations are those locations that will give an optimized compromise for moire at each of the discrete areas. Next, the corresponding tie bar shadow locations on the screen are determined, taking into account the angles of the screen slope at the discrete areas. The corresponding tie bar pitches are then determined on a formed contoured shadow mask, taking into account the mask to screen spacing at each of the discrete areas. Then, the tie bar pitches on the unformed flat mask are calculated, by subtracting the stretch caused by the mask formign step. The stretch is determined by actual measurements of vertical pitch at the discrete areas on the apertured formed mask and by comparing these measurements with measurements made on the flat mask prior to forming. Finally, a least squares fitting is performed on the calculated flat mask tie bar pitches, to obtain the locations of tie bars at all areas on the flat mask.
    • 制造彩色显像管荫罩的改进方法包括首先构造形成为圆顶形轮廓掩模的有孔平面掩模。 面具具有两个长边和两个短边的矩形周边。 掩模具有长轴，其穿过掩模的中心并且平行于长边，并且短轴穿过掩模的中心并平行于所述短边。 掩模包括在基本上平行于短轴的列中对准的狭缝状孔。 每个柱中的相邻孔径由掩模中的连接条分开，柱中的连接杆之间的间距是掩模上特定位置处的连杆间距。 改进包括对于给定的扫描线间距，在从管的观察屏幕前方的距离观察时，在几个离散区域处计算期望的连接条阴影位置的第一步骤。 所需的连接条阴影位置是将为每个离散区域的莫尔条件提供优化折中的位置。 接下来，考虑到离散区域处的屏幕斜率的角度，确定屏幕上的对应的连接条影子位置。 然后在形成的轮廓的荫罩上确定对应的拉杆间距，同时考虑到每个离散区域处的屏蔽间隔。 然后，通过减去由掩模形成步骤引起的拉伸来计算未形成的平面掩模上的拉杆间距。 通过在孔形成的掩模上的离散区域处的垂直间距的实际测量并且通过将这些测量与在形成之前在平面掩模上进行的测量进行比较来确定拉伸。 最后，对所计算的平面罩连杆杆间距进行最小二乘拟合，以获得平面罩上所有区域的连杆的位置。
