A method and apparatus for laying a pipeline in the underground. First, a pilot pipeline of small diameter is laid in the underground between a departure pit and an arrival pit. A cutter head having a cutter drum mounted thereto is attached to the trailing end of the pilot pipeline. By rotating the cutter drum, earth and sand is excavated and taken in inside the cutter drum where earth and sand is converted into a slurry state by injecting therein water through a water supply pipe mounted to the pilot pipeline. The slurried earth and sand is then discharged through a slurry discharge pipe mounted to the pilot pipeline to a tank provided in the arrival pit. By actuating a propulsion jack installed in the departure pit, the cutter head is propelled into the underground and then a pipe to be laid is connected to the rear end of the cutter head. By repeating the excavation and the propulsion steps, a pipeline of a larger diameter is laid in the underground.

The driving system which drives and rotates a flexible-disc to and from which information is written in and read out by means of a magnetic head. On the top of a driving hub the flexible-disc is attached in a detachable manner, and at the bottom part of the driving hub a driving axle is directly connected coaxially. The lower end of this driving axle itself forms the rotating axle of a direct current magnetic motor. The rotation of this motor is controlled by a rotating speed controlling system so as to rotate at speed identical to any given designated velocity.

A method of reproducing in an electrostatic copying apparatus a portion of an entire master pattern comprised of toner deposited on an electrostatic latent image onto a reproducing medium. The reproducing medium, itself, is an insulative sheet material which has a copy surface on which the selected portions will be reproduced. At least one first transparent conductive film is deposited on the back side of the copy surface of the sheet material in the area corresponding to the portion of the master pattern which will not be reproduced, and at least one second transparent conductive film is deposited along only one end of the sheet material on the same side of the material as the first conductor film. Finally, a third transparent conductive film connects the first and second films to each other. The method of producing on this reproducing medium begins by feeding one end of the sheet material opposite the end containing the second conductive film into the electrostatic copier. The copy surface of the insulative sheet material is contacted by the entire toner-coated electrostatic latent image, and the toner is electrostatically transferred to the copying surface of the sheet material in all areas except those corresponding to the conductive film on the back side of the sheet material.

In a friction stir welding apparatus, workpiece fixing surface plates (3a, 3b) are installed on a framework (1). In addition, a welding apparatus main body (8) including a bobbin tool (5) having a probe (5a) protruding upward from a gap (4), a spindle (6) configured to attach the bobbin tool (5) to an upper end section thereof, and a spindle driving apparatus (7) configured to pivot the spindle (6) is movably installed at the framework (1) in a longitudinal direction of the gap (4) via linear guide mechanisms (9) installed at both sides of the welding apparatus main body (8). Further, a moving apparatus (10) is installed to move the welding apparatus main body (8) in the longitudinal direction of the gap (4). According to the friction stir welding apparatus, since the welding apparatus main body (8) is supported by the framework (1) via both of the linear guide mechanisms (9), a large welding reaction force can be sufficiently received. In addition, since workpieces (2a, 2b) are welded from a lower side, the workpiece size is not limited by a size of the apparatus.
