    • The present invention provides a marine reversing gear assembly, wherein a manual directional control valve 7a and an electromagnetic directional control valve 7b for a forward/reverse directional control valve 7 for hydraulic oil supply circuit 10 have a common structure of an oil line joint surface for the hydraulic oil supply circuit 10 for friction discs of a forward clutch 2f and a reverse clutch 2a, and the forward/reverse directional control valve 7 for the hydraulic oil supply circuit 10 can be changed to either the manual directional control valve 7a or the electromagnetic directional control valve 7b by exchanging spools 7c or 7e of the manual directional control valve 7a or the electromagnetic directional control valve 7b. Therefore, the operational manner of the forward/reverse directional control valve for the hydraulic oil supply line of a marine reversing gear assembly can be changed quite easily between the manual directional control valve and the electromagnetic directional control valve.

    • In constructing an optical wiring network for connecting optical information processors on a plurality of floors of a building by pressure-feeding an optical fiber cable through a tube using a compressed gas provided by a pressure feeding apparatus, a cable installation route and a pressure of the compressed gas at the entrance end of the tube are first determined so that thrust exerted on the optical fiber cable by the compressed gas is greater, at every point of the route, than resistance including weight of the optical fiber cable in an ascending portion of the route and friction between the optical fiber cable and the tube. After installation of a tube in the building along the determined route, an optical fiber cable is fed through the installed tube with the pressure feeding apparatus, employing the above-determined pressure of the compressed gas at the entrance end.
