    • An apparatus for inspecting a surface of a disk comprises an indexing table having chucks for holding said disks respectively, said chucks being arranged angularly at regular intervals on the indexing table. Each of disks held by the respective chucks is moved by indexing revolution of the indexing table sequentially from a loading station where the disk is loaded onto the chuck, to an inspection station where the disk is inspected for a surface of the disk and then to an unloading station where the inspected disk is unloaded to the outside of the apparatus. The disk loaded onto a chuck at the loading station is driven to rotate until the disk gets to a predetermined rate of revolution before the disk arrives at the inspection station. The disk which has already get to the predetermined rate of revolution can be immediately inspected for the surface of the disk in the inspection station by an inspection device.
    • 用于检查盘的表面的装置包括具有用于分别保持所述盘的卡盘的分度台,所述卡盘在分度台上以规则的间隔成角度地布置。 由相应卡盘保持的每个盘通过将分度表的旋转顺序地从盘装载到卡盘上的装载站顺序地移动到检查盘,其中检查盘被检查到盘的表面,然后到 卸载站,被检查的盘被卸载到设备的外部。 驱动装载站上的卡盘上的盘旋转,直到盘到达检查台前达到预定的转速。 已经达到预定转速的盘可以通过检查装置立即检查检查台中盘的表面。

    • The outer surface of a panel effective section of a vacuum envelope is substantially flattened. A phosphor screen is formed on the inner surface of the effective section and includes stripe-shaped phosphor layers and light absorption layers arranged in parallel. The panel effective section is formed such that a corner portion is 8 mm to 15 mm thicker than the central portion and the transmittance of the central portion is set at 40% to 60%. The phosphor screen is formed such that the ratio of the width of a light absorption layer to the pitch of phosphor layers in the central portion of the panel effective section is larger than or equal to that in the peripheral portion thereof. A shadow mask is opposed to the phosphor screen and has a mask body in which a number of electron beam passage apertures are formed. The pitch of apertures formed in the peripheral portion of the mask body is 1.3 to 1.4 times as large as that of apertures formed in the central portion thereof.
    • 真空外壳的面板有效部分的外表面基本上变平。 荧光屏形成在有效部分的内表面上,并且包括平行布置的条形荧光体层和光吸收层。 面板有效部形成为使角部比中心部厚8mm〜15mm,中心部的透射率为40%〜60%。 荧光屏被形成为使得在面板有效部分的中心部分中的光吸收层的宽度与荧光体层的间距的比率大于或等于其周边部分中的荧光体层的间距的比率。 荫罩与荧光屏相对,并具有形成多个电子束通过孔的面罩主体。 形成在面罩主体的周边部分的孔的节距是其中心部分形成的孔的间距的1.3〜1.4倍。

    • A shadow mask is provided in an envelope of a color cathode ray tube. The shadow mask includes a mask body having a number of electron beam apertures, and a mask frame having side walls equipped on the peripheral portion of the mask body. The side walls of the mask frame includes a pair of long side walls extending in parallel with the long axis X and a pair of short side walls extending in parallel with the short axis Y. Beads and are respectively formed on the long side walls and the short side walls. The length of each bead of the long side wall along the long axis is set in a range of 55% to 80% of the length of the long side walls along the long axis, and a width of the bead in the tube axis direction is set in a rage of 40% to 75% of the maximum width of the long side walls in the tube axis direction. The length of each bead of the short side wall along the short axis is set in a range of 55% to 80% of the length of the short side walls along the short axis, and a width of the bead in the tube axis direction is set in a rage of 40% to 75% of the maximum width of the short side walls in the tube axis direction.
    • 荫罩设置在彩色阴极射线管的外壳中。 荫罩包括具有多个电子束孔的面罩主体,以及具有配置在面罩主体的周边部分上的侧壁的面罩框架。 荫罩框架的侧壁包括与长轴X平行延伸的一对长侧壁和与短轴Y平行延伸的一对短边壁。珠粒分别形成在长侧壁上和 短边墙。 沿着长轴的长边壁的每个胎圈的长度被设定为沿着长轴的长边壁的长度的55%至80%的范围,并且胎圈在管轴方向上的宽度为 设置在管轴方向上的长侧壁的最大宽度的40%至75%的范围内。 沿着短轴将短边壁的每个珠的长度设定在短边的短边壁的长度的55%〜80%的范围内,并且管轴方向的珠的宽度为 设置在管轴方向上短边壁的最大宽度的40%至75%的范围内。
