摘要： An improved color picture tube includes a shadow mask which 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 the 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. The widths of the tie bars are graded in dimension. The grading is at least partially related to the amount of tie bar stretch occurring in a similar size mask having different tie bar widths.

摘要： An improved color picture tube includes a mask that has an aperture array including 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. The tie bars in one column are offset in the longitudinal direction, paralleling the minor axis, from the tie bars in each adjacent column. The spacing between tie bars in a column is the tie bar pitch at a location on the mask. A first set of columns, that includes every other column, has increased tie bar pitch at the ultimate end apertures, as compared to the tie bar pitch at the penultimate apertures in each of the columns. In a second set of columns, every other column not in the first set, has decreased tie bar pitch at the ultimate end apertures, as compared to the tie bar pitch at the penultimate apertures in each of the columns. The last tie bars before the ends of the aperture columns in the second set are shorter than the next to the last tie bars, measured in the longitudinal direction of the columns, and the ultimate apertures at the ends of all of the aperture columns end on a smooth border line.

摘要： An improved color picture tube includes a shadow mask and a dot screen, wherein the mask is rectangular and has two horizontal long sides and two vertical short sides. The long sides parallel a central major axis of the mask and the short sides parallel a central minor axis of the mask. The mask includes an array of apertures arranged in vertical columns and horizontal rows. Apertures in one row are in different columns than are the apertures in adjacent rows. The vertical spacing between apertures in the same column is the vertical pitch of the apertures and the horizontal spacing between apertures in the same row is the horizontal pitch of the apertures. The improvement includes the horizontal pitch of the apertures increasing from the minor axis to the short sides of the mask and decreasing from the major axis to the long sides of the mask. Also, along the major axis, the vertical pitch of the mask decreases from the center to the short sides of the mask and, adjacent the long sides of the mask, it increases from the minor axis to the corners of the mask.

摘要： The present invention is an improvement in a method of screening a line screen slit mask color picture tube that includes coating a faceplate panel of the tube with a photosensitive material, inserting a slit shadow mask into the panel and exposing the photosensitive material by passing light from a line light source through a misregister correction lens and through the slits of the mask. The improvement comprises positioning a skew correction lens between the line light source and the misregister correction lens during exposure of the photosensitive material. The skew correction lens has a surface with a general overall cylindrical shape with deviations from the cylindrical shape being in the four corners of the skew correction lens.

摘要： The base comprises a tubular housing adapted to fit over the exhaust tubulation of an electron tube stem, and a wafer flange extending outwardly from the open end thereof. The flange is apertured to receive an array of conductors of the stem. A recess is provided in the wafer flange facing the stem and a passageway communicating therewith is provided through the base separate from the housing cavity for the purpose of injecting a dielectric material into the recess around some of the stem conductors. The passageway may, e.g., be through the flange or in the housing wall.A shoulder is provided on the recessed face of the wafer flange to provide relief for random protuberances on the periphery of the stem to permit non-tilted mounting of the base on the stem.

摘要： A resonant degaussing circuit provides rapid recovery for use with computer monitors or video display apparatus where frequent movement of the display apparatus occurs. The degaussing circuit comprises a capacitor in parallel with a degaussing coil. Triggering of an SCR causes the capacitor to discharge, so that it resonates with the degaussing coil to produce the desired AC degaussing current. The SCR is triggered only when the vertical deflection current is substantially zero, in order to eliminate interference of the vertical flux with the degaussing current.

摘要： A wafer type tube base is secured to a stem structure of an electron tube. The base includes a cup which fits over an exhaust tubulation of the stem and a wafer flange which extends radially outward from the open end of the cup and abuts the stem wall. The flange has an array of apertures for receiving an array of stem conductors therethrough. An adapter is provided for converting the wafer-type base to a pin-protector type base. The adapter comprises a hollow cylindrical member having a plurality of longitudinally extending ribs on its outer surface. The adapter telescopes over the exhaust tubulation cup and receives the stem conductors in the grooves between the ribs. Means for interlocking the adapter to the wafer base comprises a pair of openings in the cylindrical wall of the cup and a pair of inwardly projecting fingers at an end of the adapter which are adapted to be received in the openings and are sized to engage the cup wall in a frictional snap fit.

摘要： 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.
