    • In a flooring panel, plural blocks are held by a holding member of a flexible material so that one section is formed by at least one block with a space for laying a cable defined between adjacent sections. A cover member overlying these spaces is arranged to present a surface continuous with the upper surface of the blocks to form a flat, top surface of the flooring panel. The flooring panel is in the form of a rectangular modular flooring panel of at least one shape and size. A plurality of cable laying spaces in communication with one another are defined by laying a plurality of such modular flooring panels on a building floor as a function of the amount of cables to be laid. In such a manner, the operation of cable laying and construction of the flooring panels on the permanent building floor may be performed more efficiently while the interaction between the cables of different kinds is minimized.
    • 在地板面板中,多个块由柔性材料的保持构件保持,使得一个部分由具有用于铺设在相邻部分之间的电缆的空间的至少一个块形成。 覆盖这些空间的覆盖件被布置成呈现与块的上表面连续的表面,以形成地板面板的平坦的顶表面。 地板面板为至少一种形状和尺寸的矩形模块化地板面板。 通过将多个这样的模块化地板面板放置在建筑物地板上,根据要铺设的电缆的数量来定义彼此连通的多个电缆铺设空间。 以这种方式,可以更有效地执行在永久建筑物地板上的地板镶板的铺设和施工的操作,同时使不同种类的电缆之间的相互作用最小化。

    • A transmission system which couples a plurality of transmission devices to a control device includes a first transmission device which is one of the plurality of transmission devices; a first calculation circuit which calculates a first difference value indicating a frequency difference value between a common clock supplied from the control device and a first clock as a clock used in the first transmission device; and a transmitter which reports the first difference value to a second transmission device other than the first transmission device, wherein the second transmission device comprises: a second calculation circuit which calculates a second difference value indicating a frequency difference value between the common clock and a second clock used in the second transmission device, and a frequency controller which controls an oscillator generating the second clock so that the second difference value approaches the first difference value reported from the first transmission device.
    • 将多个传输设备耦合到控制设备的传输系统包括作为多个传输设备之一的第一传输设备; 第一计算电路,其计算指示从所述控制装置提供的公共时钟与所述第一时钟之间的频率差值作为所述第一发送装置中使用的时钟的第一差值; 以及向所述第一发送装置以外的第二发送装置报告所述第一差分值的发送机,其中,所述第二发送装置包括:第二计算电路,其计算表示所述公共时钟与第二发送装置之间的频率差值的第二差分值 在第二发送装置中使用的时钟,以及频率控制器,其控制产生第二时钟的振荡器,使得第二差值接近从第一发送装置报告的第一差值。
