    • To realize a high-quality flat-face type of color cathode ray tube by combining a tint panel with a pressed mask, the outer surface of the panel of the color cathode ray tube is made nearly flat and the inner surface of the panel is curved in a concave shape, and the long-length direction pitch of slots formed in an aperture region 2 of a pressed mask 1 to be disposed close to the inner surface and the connection-direction width of each of bridges which connect the slots are made different between a central portion (A) and a peripheral portion (B) in the apertured region 2 of the pressed mask 1, whereby the ratio of bridges per unit area is made larger in the central portion (A) than in the peripheral portion (B) or the opening rate of slots per unit area is made larger in the peripheral portion (B) than in the central portion (A). According to this construction, the mechanical strength of the central portion (A) of the pressed mask becomes large, whereby it is possible to restrain the occurrence of undesired deformation of the pressed mask 1 due to the increase of the radius of curvature of the central portion (A) and it is possible to uniformize brightness over the entire screen.
    • 为了通过将色调面板与压制掩模组合来实现高质量的平面型彩色阴极射线管,彩色阴极射线管的面板的外表面几乎是平的,并且面板的内表面是弯曲的 凹陷形状,并且形成在靠近内表面的按压掩模1的孔区域2中的槽的长度方向节距和连接槽的每个桥的连接方向宽度被制成不同 在压制掩模1的有孔区域2中的中心部分(A)和周边部分(B)之间,由此在中心部分(A)中每单位面积的桥梁的比例比在周边部分(B )或周边部(B)中的每单位面积的开口率比中央部(A)大。 根据这种结构,压制掩模的中心部分(A)的机械强度变大,由此可以抑制由于中心部分的曲率半径的增加而使受压掩模1发生不期望的变形 部分(A),并且可以使整个屏幕上的亮度均匀化。

    • A cathode-ray tube that has an electron gun including a final-stage main lens made up of a last accelerating electrode and a focusing electrode and having a focus action stronger in horizontal direction than in vertical direction, an electron lens of a first kind formed between the divided focus electrodes and having a focus action stronger in the vertical direction than the horizontal direction to vary the cross sectional shape of an electron beam with an increase of the deflection amount, an electron lens of a second kind formed between the divided focus electrodes for weakening the lens strength with an increase of the deflection amount of an electron beam, and an electron lens of a third kind made up of at least one electrode constituting a three electrode section and having a focus action stronger in the horizontal direction than in the vertical direction. The dynamic focus voltage which decreases with an increasing deflection amount is reduced. The horizontal diameter of an electron beam spot is reduced on the central area of the screen.

    • A self-chargeable timepiece includes a pair of small and large capacitors having respective small and large capacities and selectively disconnectably connected at their respective terminals to time-keeping circuitry and a solar cell. The pair of small and large capacitors cooperate with each other during the momentary operation of the solar cell for selectively receiving and storing the electric charge to develop respective terminal voltages across their respective terminals even after the momentary operation of the solar cell. A detector periodically detects the terminal voltages of the small and large capacitors during the time-keeping operation. A switching circuit responds to the detected terminal voltages for selectively connecting and disconnecting the small and large capacitors to and from the time-keeping circuitry to enable the small and large capacitors to selectively power the time-keeping circuitry. A regulating circuit operates when the time-keeping circuitry is powered by the small capacitor for regulating the detector to effect the periodical detection of the terminal voltages at relatively short time intervals and operates when the time-keeping circuit is powered by the large capacitor for regulating the detector to effect the periodical detection of the terminal voltages at relatively long time intervals.
