    • A digital attenuator is disclosed which is capable of having the output PCM signal attenuated nearly in proportion to the input PCM signal level based upon simple logic operations ofP.sub.out = .alpha. P.sub.in + NwhereP.sub.out = output PCM signalP.sub.in = input PCM signal processed by a compressor.alpha. = a real number satisfying the condition 0 O, to obtain the sum .alpha.P.sub.in + N, the output signal .alpha.P.sub.in, which is obtained in the manner described above, is added to a specific pattern representing N which is generated by a specific pattern generating circuit. The above sum is compared with P.sub.in and when the former is larger than or equal to the latter, P.sub.in becomes P.sub.out, while when the former is less than the latter, the sum is derived as P.sub.out. Thus, an attenuation nearly proportional to the input FCM signal level may be attained.
    • 公开了一种数字衰减器,其能够基于Pout = alpha Pin + N的简单逻辑运算使输出PCM信号几乎与输入PCM信号电平成正比衰减,其中Pout =输出PCM信号Pin =输入PCM信号 压缩器α=满足条件0 <α<1的实数,N =大于或等于0的实数。

    • A tongs apparatus includes an upper frame suspended from a crane, a pair of first arms journaled on the upper frame, a pair of second arms journaled on the first arms and disposed to cross each other, and a supplemental-holding-force apparatus. The supplemental-holding-force apparatus comprises a chain motor; a chain wound and unwound by the chain motor; a ring-shaped member connected to the chain and having an elongated hole; and a lifting metal fitting having a guide pin slidably engaged with the ring-shaped member. The chain is wound or unwound by the chain motor in order to move the ring-shaped member vertically to thereby supplement a holding force generated through closing of the second arms.
    • 夹钳装置包括从起重机悬挂的上框架,在上框架上轴颈的一对第一臂,一对第二臂,其位于第一臂上并彼此交叉设置,以及辅助保持力装置。 补充保持力装置包括链式电动机; 由链条电机缠绕并展开的链条; 连接到链条并具有细长孔的环形构件; 以及具有与所述环形构件可滑动地接合的引导销的起重金属配件。 链条由链式电动机缠绕或退绕,以便垂直移动环形构件,从而补充通过关闭第二臂产生的保持力。

    • A display control device includes a display panel for displaying data containing textual and/or drawing data, a display buffer for storing data to be displayed on the display panel, a display control section for controlling display of the display panel, a backlight for illuminating the display panel, an illumination instruction section for outputting a backlight illumination instruction, and an illumination control section for controlling the illumination of the backlight according to the backlight illumination instruction from the illumination instruction section. The display control section changes a display configuration of the data to be displayed on the display panel when the illumination instruction section outputs the backlight illumination instruction.
    • 显示控制装置包括用于显示包含文本和/或绘图数据的数据的显示面板,用于存储要显示在显示面板上的数据的显示缓冲器,用于控制显示面板显示的显示控制部分, 显示面板,用于输出背光照明指示的照明指示部,以及根据来自照明指示部的背光照明指示来控制背光的照明的照明控制部。 当照明指示部输出背光照明指示时,显示控制部改变要在显示面板上显示的数据的显示结构。
