摘要： A funnel of a cathode ray tube includes a yoke attachment portion on which a deflection yoke is mounted so as to deflect the electron beam emitted from an electron gun along horizontal and vertical axis. At least one cross section of the yoke attachment portion, perpendicular to the tube axis, has an inner contour which is substantially rectangular with four sides. The sides are defined by convexities curved toward the tube axis and each having a peak on the horizontal or vertical axis. The inner contour of the cross section faces the electron beam passage region with a substantially constant gap.

摘要： A cathode ray tube includes a vacuum envelope having a substantially rectangular panel, a cylindrical neck, and a funnel connecting the panel and the neck. A phosphor screen arranged on the inner surface of the panel generates luminescence upon impingement of electron beams, which are generated by an electron gun assembly disposed in the neck. In order to create a image visible through the panel, a deflection yoke is mounted on the outer surface of the funnel to generate a magnetic field in the funnel, deflect the electron beams, and thereby scan the phosphor screen. According to the present invention, the portion of the funnel over which the deflection yoke is mounted is formed such that the power required to generate a deflection field capable of scanning substantially the entire phosphor screen may be reduced. To this end, the funnel is formed over a predetermined range along a first axis coincident with the axis of symmetry of the cylindrical neck such that at least one cross section of the inner and outer funnel perpendicular to the first axis has a non-circular shape and a maximum diameter along a direction other than those of the major and minor axes of the substantially rectangular panel. Moreover, within this predetermined range, the point on the funnel's cross section that is furthest from the first axis is not located along the direction of the panel's diagonal axis.

摘要： An electron gun which emits three electron beams consisting of a center beam and paired side beams arranged in line in the horizontal axis is arranged in the neck of the vacuum envelope. A neck-side orbital correction coil unit for over-converging the side beams running toward the peripheral portion of a phosphor screen and a panel-side orbital correction coil unit for under-converging the side beams running toward the peripheral portion of the phosphor screen are provided between the cathode of the electron gun and the phosphor screen. The panel-side orbital correction coil unit has four orbital correction coils provided inside the magnetic core of a deflection yoke. Each orbital correction coil includes paired coil wires extending in the tube axis direction. One of the coil wires is positioned at an angle of 10 to 30° to the vertical axis, and the current flows from the neck side toward the panel through this coil wire. The other coil wires are positioned at an angle of 60 to 90° to the vertical axis, and the current flows from the panel side toward the neck through this coil.

摘要： A color cathode-ray tube having at least one trajectory correction device including a plurality of trajectory correction coils, and a current supply circuit for supplying current to these coils. The trajectory correction device functions to over-converge or under-converge a pair of side beams at a peripheral portion of the phosphor screen relative to a center of the phosphor screen. The trajectory correction device produces a magnetic field such that there is a position in the produced magnetic field where no force is exerted on the three electron beams. This position is separated from a plane including a tube axis, and a first direction or a second direction. In this color cathode-ray tube apparatus with this structure, no degradation occurs in focusing or distortion characteristics even where the trajectory correction device is provided, for example, in realizing a flat screen by using a press-formed shadow mask.

摘要： A vacuum envelope of a cathode ray tube includes a rectangular panel having an inner surface where a substantially rectangular phosphor screen is formed, a neck in which an electron gun is provided, and a funnel connected between the panel and the neck. The funnel has a first portion having a large diameter and positioned on the phosphor screen side, and a substantially truncated quadrangular pyramid-like second portion positioned on the neck side. From the second portion to the neck, a deflection yoke is mounted on the outer surface of the funnel. Where the vacuum envelope is cut along a plane including a tube axis, the shapes of the cross-sections of the first and second portions have an inflection point at the boundary between the first and second portions. The end of the deflection yoke on the phosphor screen side is positioned near the inflection point.

摘要： The non-volatile memory includes a word line potential control circuit in a non-volatile memory having a memory cell array, word lines, bit lines, an X decoder, a bit line selector, and a source voltage applying circuit. The word line potential control circuit is provided with a threshold voltage detection circuit and a plurality of word line potential control transistors. The threshold voltage detection circuit includes a threshold voltage holding memory cell transistor having a simultaneously processed identical structure as the memory cell transistors and disposed adjacent to the memory cell transistors so as to hold a threshold voltage after ultraviolet light erasing. The threshold voltage detection circuit detects whether a threshold voltage of the threshold voltage holding memory cell transistor is above or below a predetermined reference voltage. Each of the word line potential control transistors has a drain connected to a corresponding one of the word lines and turns on and off in accordance with a detection result from the threshold voltage detection circuit thereby controlling respective potentials of the word lines to one of first and second potentials. In this way, variations in the threshold voltages after the electrical erasing can be reduced.
