    • A semiconductor device testing apparatus in which ICs to be tested are transferred to a test tray TST in a loader section, the test tray is transported into a test section to test the ICs, after the completion of the test, the tested ICs on the test tray are transferred from the test tray onto a general-purpose tray in an unloader section, and the test tray which has been emptied of the tested ICs is transported to the loader section, and the above operation is repeated, and which can detect whether there is an IC on the test tray or not is provided. An IC detecting sensor for monitoring whether an IC exists on the test tray or not is provided at at least one of the positions between the unloader section and the loader section, the loader section and the test section, and the test section and the unloader section. A through-hole is provided in the bottom portion of each IC carrier mounted to the test tray, and whether an IC carrier mounted to the test tray is empty or not is determined by detecting light transmitted through the through-hole by the IC detecting sensor.
    • 将要测试的IC转移到装载器部分中的测试托盘TST的半导体器件测试装置,在测试完成之后将测试托盘运送到测试部分以测试IC,测试的IC在测试中 托盘从测试托盘转移到卸载机部分的通用托盘中,并且已经将被测试的IC排空的测试托盘被运送到加载器部分,并且重复上述操作,并且可以检测是否存在 是否提供了测试托盘上的IC。 在卸载部与装载部之间,装载部和试验部以及试验部和卸载部之间的至少一个位置设置有用于监视IC上是否存在IC的IC检测传感器 。 通过检测通过IC检测传感器透过通孔的光来确定安装在测试托盘上的每个IC载体的底部以及安装在测试盘上的IC载体是否为空的通孔 。

    • A color picture tube, wherein a set of three electron beams emitted from respective three electron-emitting members of an in-line type electron gun, or from respective three electron guns, is projected through slot-shaped apertures of a shadow mask onto a screen, and sets of each three luminous strips are formed separated from each other and surrounded by light absorbing black film, and the three electron beams selectively energize the luminous strips to emit luminous color images, the length and width of the slots on the shadow mask and those of the phosphor strips having specified correlations in the central part of the picture screen and the shadow mask, and different correlations in the corner parts of the screen and the shadow mask so that color picture reproduction in contrast, brightness and color balance is satisfactory over the entire screen.
