    • An apparatus and method for excavating tunnels with a shield and slurry while detecting and preventing excess excavation in high water content soft ground wherein, in each of feeding system of slurry to tunnel face and discharging system of a mixture of slurry and excavated soil or the like as well as gushing water from the tunnel face out of working area, the respective volumes of the slurry and mixture passing through the respective systems are measured in positions close to the tunnel face, the volume of the excavated soil or the like is determined with the difference between both volumes while the amount of propelling a tunnelling machine is determined as an excavated space volume of the tunnel, the respective values of the excavated soil volume and excavated space volume are compared with each other, whereby the amount of propelling the machine, fed amount of the slurry or discharging amount of the mixture can be properly adjusted so that the difference between said values will be made substantially zero.
    • 一种用于在检测和防止高含水量软土地层中的过量挖​​掘的同时,利用盾构泥浆挖掘隧道的装置和方法,其中,在浆料到隧道面的每个供给系统和浆料和挖土等的混合物的排出系统 以及从隧道面向工作区域涌出的水,在靠近隧道面的位置处测量通过各个系统的浆料和混合物的相应体积,挖掘的土壤等的体积由 两个容积之间的差异,而推进隧道机的量被确定为隧道的挖掘空间体积,挖掘的土体积和挖掘的空间体积的相应值彼此进行比较,由此推进机器的量 可以适当地调节浆料的量或混合物的排出量,使得所述值之间的差异将被限制 基本上为零。

    • The image forming apparatus has exposing device, conveying device, and sheet detecting device for detecting the sheet conveyed by the conveying device, which is disposed between the transferring portion and the conveying device, and control device for judging whether or not it is possible to start exposure by the exposing device before the leading edge of the sheet conveyed by the conveying device reaches the sheet detecting device after the leading edge of the sheet passes through the conveying device and for controlling so that causing the sheet conveyed by the conveying device is stopped in front of the sheet detecting device until it is determined that it is possible to start exposure by the exposing device. In the image forming apparatus, the image forming apparatus starts to form a latent image by the exposing device based on the detection of the sheet by the sheet detecting device.
    • 图像形成装置具有曝光装置,输送装置和纸张检测装置,用于检测由输送装置输送的纸张,该纸张设置在转印部分和输送装置之间;以及控制装置,用于判断是否可以开始 在由输送装置输送的纸张的前端在纸张的前缘通过输送装置之后到达纸张检测装置并且进行控制以使得由输送装置输送的纸张停止时,曝光装置的曝光 直到确定可以由曝光装置开始曝光为止。 在图像形成装置中,图像形成装置基于片材检测装置对片材的检测,开始通过曝光装置形成潜像。
