    摘要: A tunnel lining process and an apparatus for use in the process in the prior art are improved in order to greatly enhance a lining speed and to facilitate the work of placing concreate for lining. The improvements reside in that a pressing form for pressing a tunnel concrete lining and a side form to be positioned on the side of the pressing form opposite to an already placed concrete lining are constructed as separate bodies in distinction from the prior art. After the pressing form and the side form have been disposed along an excavated surface of a tunnel, lining concrete is placed in a space delimited by the both forms, the excavated surface and the already placed concrete lining so as to press the lining concrete onto the excavated surface to be lined. Thereafter the pressing form is displaced along the side form and in parallel to the surface to be lined, and the steps of placing lining concrete and displacing the pressing form are repeated until placing of concrete over the entire length of the side form is completed. Then the side form is displaced to the next lining region after the finally placed concrete has revealed its mechanical strength. The aforementioned steps are repeated. A tunnel lining apparatus favorably employed upon practicing the above-described process is also disclosed.

    摘要: A method and apparatus for transmitting document data enabling transfer of document data over a communication path assigned the highest possible priority among a plurality of communication paths. First, an attempt is made to transfer document data over the highest-priority communication path. If the attempt has failed, the document data are transferred over a communication path which is lower in priority than the highest-priority communication path. After information for one page of text data has been transferred over the lower-priority communication path, an attempt is again made to transfer the remaining part of text data over the highest-priority communication path.

    摘要: A submerged tundish nozzle for continuous casting wherein substantially H-shaped delivery ports are opened outward on the outer periphery of a nozzle closed at the lower end as opposed to the short side walls of a mold and, as required, said delivery ports are formed as directed a little upward or a deflecting plate of an arrowhead-shaped cross-section is set at a small distance in front of the delivery port.Further, substantially I-shaped delivery ports may be made between those delivery ports.
