摘要： When laying a conduit comprised of double-wall pipes A, each of which comprises inner pipe 1 and outer pipe 2, the smooth propulsion of double-wall pipes is possible by injecting lubricant into a space between the outside of double-wall pipes and the ground on a scheduled line along which conduit B to be laid is divided into section, each having a given length based upon the distance over which the effect of the lubricant can be maintained. Lubricant is injected from the double-wall pipes which is to be positioned at the heads in the respective sections 1 to n of supply pipes 3 which are provided between inner pipe 1 and outer pipe 2 of double-wall pipe A. Supply pipes of double-wall pipe A which has been propelled are connected with supply pipes of a new double-wall pipe, wherein the number of supply pipes connected with each other is determined for the respective sections. Lubricant is supplied from the upstream side and from the downstream side of the propelling direction to double-wall pipes. After conduit B has been laid, back-filling material as a filler is supplied to supply pipes 3 so that a space formed between the outside of double-wall pipes 23 and the ground is filled with filler. Sheath pipes 23 are provided between inner pipes 1 and outer pipes 2. After conduit B has been laid, back-filling material, as inside-filling material, is supplied to sheath pipes 23 so that a space between the outside of double-wall pipes and the ground is filled with inside-filling material.

摘要： A conduit comprised of double-wall pipes A is laid in the ground by the pipe-jacking method. Each of double-wall pipes A comprises inner pipe 1 and outer pipe 2 and is provided with sheath pipe 4 between inner pipe 1 and outer pipe 2 and with check valve 7. Winch 11 is mounted in tunneling machine 6. Wire 12 wound on winch 11 is inserted into sheath pipe 4 and the forward end of wire 12 is sent to start vertical shaft C through sheath pipe 4, and connected with cleaning member 24, injecting member F, and supply pipe 14. Cleaning member 21, injecting member F, and supply pipe 14 are moved in sheath pipes 4 by driving winch 7. When injecting member F is opposed to check valve 7, packing means 19, 20 are inflated to be brought into contact with the inside of sheath pipe 4 by which injecting member F is fixed to sheath pipe 4. Lubricant or back-filling material is sent to a space between packing means in sheath pipe 3, and injected through check valve 7 into space 9 between the outside of outer pipe 2 and the ground.

摘要： An numerical control (NC) device capable of machining a workpiece with high accuracy by accurately commanding a feed speed of a tool, even if a sudden change occurs in an actual speed of a spindle motor. If a rotational speed of a spindle changes, a change amount calculation/storage device calculates and stores a change amount on the basis of the rotational speed already detected. A rotational speed detected by a rotational speed detection device is corrected thereafter according to the change amount, and a proper feed speed is commanded from a feed speed control device. If thread cutting is carried out by employing the NC device, the tool feed speed is commanded in proportion to the actual speed of the spindle motor, and therefore, even though the rotational speed of the spindle motor is lowered at the moment the workpiece is started to be subjected to thread cutting by the tool, a move command signal with a proper tool feed speed is outputted.
摘要翻译：即使主轴电动机的实际速度发生突然变化，也能够通过准确地指示刀具的进给速度，高精度地加工工件的数控装置（NC）装置。如果主轴的转速改变，则变化量计算/存储装置根据已经检测到的转速来计算和存储变化量。然后，由转速检测装置检测的转速根据变化量进行校正，并且从进给速度控制装置指示适当的进给速度。如果通过使用NC装置进行螺纹切削，则与主轴电机的实际速度成比例地指定刀具进给速度，因此即使在工件启动时主轴电动机的转速降低要通过工具进行螺纹切削，输出具有适当的加工速度的移动指令信号。
