Abstract: A resin-coated ribbed steel pipe that is provided with an axially extending rib that is made from the same material as the coating and forms a hold groove is fed forward and bent along with the rotation of a shaping roller that is provided with an accommodating groove having a shape identical to the half of the cross section of the pipe that includes such rib and also has a protruding wheel that inserts itself into the hold groove as the pipe is fed forward, the reaction force created thereby being managed by a device that, possessing a shape identical to the other half of the cross section of the pipe, suppresses the reaction force and yet allows the feeding of the pipe.

Abstract: A gravity-feed flow rack apparatus for multiple articles with rack modules arranged vertically.The rack apparatus include main module, front and rear auxiliary modules having article conveyance skid rails, insert joint for joining said modules, tiltable stopper means for serially advancing articles on said module, and control means performing control of desired operation condition of the rack apparatus.The rack apparatus may be a constructionally changeable in desired number and spaces of the rack modules in which flexible change is desired.

Abstract: An impact energy absorbing member is provided within a vehicle door, and due to impact load from an exterior, the impact energy absorbing member plastically deforms so as to absorb impact energy. The impact energy absorbing member includes a plurality of ribs whose respective surface directions are provided substantially along an impact load direction. Ends of the plurality of ribs are fixed to predetermined positions within the vehicle door. Reduced cross-sectional area portions are provided at fixed end sides of the plurality of ribs. The reduced cross-sectional area portions are provided such that cross-sectional areas of the plurality of ribs along a direction orthogonal to the impact load direction become smaller toward the fixed end sides of the plurality of ribs from lengthwise intermediate portions of the plurality of ribs whose lengths run along the impact load direction.

Abstract: A pipe body sheathed with a film of plastic resin. A strip of conductive plastic resin is along the entire length of the pipe body and made integral with the resin film by extrusion. The conductive strip readily discharges static electricity that may develop in a structure made of said pipes. They are connected to have their conductive strips end-to-end, thereby grounding the so built structure.

Abstract: A package containers rack frame for storing, transferring and displaying relative light-weight packages. The rack frame is constructed of a pair of side frames and a plurality of support bases which are removable from the side frames. The support bases are engaged into sockets on the side frame without disassembling of the side frames. The side frames have folding elements that are for controlling the distance between the side frames, which are folding and/or unfolding. The frame members of side frames has an adjusting member for adjusting the distance between the side frames, which thereby permits use of different width or height dimension for the containers. The support base has upward curved projections at both ends thereof for restricting in lateral movement of the containers.

Abstract: The automatic guide method for vehicles relates to an automatic guide method for the operation of unmanned vehicles which, guided along guide paths preset on the floor in factories and warehouses, etc., carry and handle various loads in a fully automated fashion, and more particularly to an automatic guide method which has a course-search function and function to prevent straying such that a vehicle which is positioned at the start of an operation with its magnetic sensor off the guide path within certain limits or which strays off course abruptly for some reason during ordinary operation, is restored to the guide path by searching and finding the magnetic tape.
