    摘要： A method of measuring a length of a conduit comprises the steps of: supplying air into a conduit to insert a filamentary body into the conduit by flow of the air; detecting arrival of a forward end of the filamentary body at an outlet of the conduit; and measuring the length of the conduit from the length of the filamentary body inserted into the conduit. An apparatus for measuring a length of a conduit, comprises an air supply device for supplying air into the conduit; a filamentary body including a wire and a plurality of elastic large-diameter members attached to the wire; and a device for detecting that a forward end of the filamentary body arrives at an outlet end of the conduit, where the length of the conduit is measured from the length of the filamentary body inserted into the conduit.

    摘要： A method and an apparatus are provided for inserting and removing a communication wire in and out of a pipeline by air flow, in which static electricity can be prevented from being generated, and a long communication wire can be inserted and removed. The communication wire is fed from a reel, and inserted into a pipeline through a blowing head. Compressed air is also sent from a compressor to the pipeline through the blowing head. A drop cylinder is attached to a T-branch on the way of the pipeline, conductive material stored therein is supplied into the pipeline at a controlled rate. A recovery bottle is attached to the outlet side of the pipeline so that the air flow blowing out of the outlet side is passed through a filter 11, and at the same time the conductive material is recovered. By making the conductive material pass through the pipeline together with the air flow, generated static electricity can be eliminated, and the communication wire can be prevented from contacting tightly with the pipeline because of the static electricity.

    摘要： In an optical cable according to the present invention, a grooved spacer has a plurality of grooves in its circumference, and the cutting direction of the grooves is inverted at predetermined periods. Optical fibers are received in the respective grooves. On the circumference of the grooved spacer, a linear member is provided around the grooved spacer along the longitudinal direction of the optical cable at a predetermined period. The linear member is fixed to the grooved spacer by welding or bonding in the portions where they touch the outer circumferences of the grooved spacer so as to restrain the optical fibers. The linear member restraining the optical fiber to be taken out are cut in positions above the groove in which the optical fiber is received so that the required optical fiber can be taken out.

    摘要： The invention relates to an apparatus for laying an optical fiber unit with a pressure fluid into a previously laid duct line. Specifically, the apparatus performs this operation by a method for causing pressure fluid to flow backward into the guide tube on the feed side of the optical fiber unit so as to generate a buoyant force, so that the load due to the frictional force in the section between the feed side and the driving means can be much reduced. Accordingly, the method according to the present invention is particularly useful for pressure-sending an optical fiber unit into a duct line having insertion resistance, for example, a vertical duct line, a duct line having fine curves, or the like.
