    • A vacuum station is used for storing sewage from a vacuum sewage pipe and then delivering the sewage to a sewage treatment plant or the like. The vacuum station includes a collection tank for collecting sewage, a plurality of vacuum pumps for depressurizing and pressurizing an interior of the collection tank, and a controller for controlling the plurality of vacuum pumps. The controller controls at least one of the vacuum pumps so as to rotate in normal direction so that the interior of the collection tank is depressurized to collect sewage into the collection tank, and at least one of the vacuum pumps so as to rotate in reverse direction when the sewage in the collection tank reaches a predetermined sewage level so that the interior of the collection tank is pressurized to discharge the sewage from the collection tank.
    • 真空站用于储存来自真空污水管的污水,然后将污水输送到污水处理厂等。 真空站包括用于收集污水的收集罐,用于对收集罐的内部进行减压和加压的多个真空泵,以及用于控制多个真空泵的控制器。 控制器控制至少一个真空泵,以便在正常方向上旋转,使得收集箱的内部被减压以将污水收集到收集罐中,并且至少一个真空泵以相反方向旋转 当收集罐中的污水达到预定的污水水平时,使得收集罐的内部被加压以从收集罐排出污水。

    • An image forming method is provided which, even when misregistration occurs in locating of a recording position of each color, can make color misalignment inconspicuous, and hence is effective in obtaining a recorded image of a high quality. An image is recorded while, for one color, unit blocks which are adjacent to each other in the main scanning direction of image recording are provided with gradation characteristics in different matrix arrangements in which front and rear portions that are obtained by division at an intermediate position in the sub-scanning direction are replaced with each other.
    • 提供了一种图像形成方法,即使在定位每种颜色的记录位置时出现重合失调,也可能使颜色偏差不显眼,从而有效地获得高品质的记录图像。 记录图像,对于一种颜色,在图像记录的主扫描方向上彼此相邻的单位块在不同的矩阵排列中具有灰度特性,其中通过在中间位置分割获得的前后部分 在副扫描方向上彼此替换。

    • The present invention provides an image conversion apparatus that converts an input image having process color components and a spot color component and represented by density data for the respective colors into a halftone dot image represented by halftone dot data. A first halftoning means changes the process color components into halftone dots, a spot color separation means separates the spot color component into two or more colors, a second halftoning means changes the two or more colors into halftone dots using, for example, a halftone dot sort which is higher in screen ruling than that of a halftone dot sort used in the first halftoning means, and a halftone dot composition means composites the halftone dots of each process color component of the two or more colors provided by the second halftoning means with the halftone dots of the corresponding process color component provided by the first halftoning means.
    • 本发明提供一种图像转换装置,其将具有处理颜色分量和专色成分的输入图像转换为由各色调的浓度数据表示为由半色调点数据表示的半色调点图像。 第一半色调装置将处理颜色分量改变为半色调点,专色分离装置将专色分量分离成两种或更多种颜色,第二半色调装置使用例如半色调点将两种或更多种颜色改变成半色调点 筛网规则比在第一半色调装置中使用的半色调点排序高的类别,并且半色调点组合装置将由第二半色调装置提供的两种或更多种颜色的每个处理颜色分量的半色调点与 由第一半色调装置提供的相应处理颜色分量的半色调点。
