    • A computer display device with digital RGB color signal lines, and horizontal and vertical synchronous signal lines. The controller comprising a means for taking out, from one of the digital RGB color signal lines which consists of an N bit digital signal, a black level signal defined as "0" or "1" in all N bits, and a means for adding the black level signal being taken out to either one of said horizontal and vertical synchronous signal lines. In addition to the controller, the present invention provides a display device including a means, provided within the display device, for extracting said black level signal from the synchronous signal with the black level signal being added, and a means for maintaining a black level potential of the display device at a predetermined value in response to the black level signal being extracted.
    • 具有数字RGB彩色信号线,水平和垂直同步信号线的计算机显示设备。 该控制器包括一个装置,用于从一个数字RGB彩色信号线中取出一个由N位数字信号,在所有N位中定义为“0”或“1”的黑电平信号,以及一个用于增加 黑电平信号被取出到所述水平和垂直同步信号线中的任一个。 除了控制器之外,本发明还提供了一种显示装置,包括设置在显示装置内的用于从添加有黑电平信号的同步信号中提取黑电平信号的装置,以及用于维持黑电平电位的装置 响应于黑电平信号被提取,显示装置的预定值处于预定值。

    • To provide a vacuum valve with an improved endurance of a bellows, a vacuum valve comprises: a valve section including a first port, a second port, a valve seat provided between the first and second ports, and a valve element movable into or out of contact with the valve seat; an actuator section including an orifice through which an operating fluid is supplied to the actuator section, and a piston coupled to the valve element, the piston being allowed to operate according to changes of pressure of the operating fluid to apply a driving force to the valve section; and a bellows which can be contracted and elongated as the valve element vertically moves upward and downward. The orifice is designed to have an effective sectional area determined so that an operating speed of the valve element and the piston is controlled to a predetermined speed for preventing damage of the bellows.
