摘要： PROBLEM TO BE SOLVED: To house layered articles with high efficiency by forming a space interposed between an article group of an upper layer and an article group of a lower layer as a travel passage layer of a carrying-in/carrying-out means of the articles, and forming an upper part and a lower part of its desired position as a raising/lowering passage division of a receiving/delivering means of the articles. SOLUTION: While rising, a receiving means 13 approaches (A1) in the arrow direction in which a delivering means 12 is arranged. The respective passing of comb teeth 121 and comb teeth 131 is mutually allowed, and an article 11 is delivered in its process. Then, in order to open the delivering means 12, a sliding movement in the arrow direction is started (A2). The receiving means 13 starts to descend in the arrow direction in the middle of the sliding movement (A3). The receiving means 13 passes through an opening, and in order to close the opening in the middle of it, the delivering means 12 restarts the sliding movement in the arrow direction (A4). The opening is closed, and it returns to a former (A1) condition position, and a delivering work procedure of the article 11 finishes.

摘要： PURPOSE:To obtain a device which can contrive an improvement in mainly fluidity in a raw compound. CONSTITUTION:This is a manufacturing plant of a raw compound wherein the same is constituted of a supply device 313 provided on the lower part of a plurality of reservoir tanks 13, 14 storing the compounded granular bodies A1, A2 and coarse grain rate confirmation devices 333, 4331, 4332, 4333, 4334 measuring a coarse grain rate of the compounded granular bodies A1, A2 to be supplied through the supply device 313 at the time of obtaining of the raw compound F2 by kneading the compounded granular bodies A1, A2, a hydraulic substance powder body B1 and compounded liquid bodies C1, C2 and the same is made into structure wherein variation control of supply rates of the compounded granular bodies each are carried out through the supply device 313 based on the coarse grain rates measured by the coarse grain rate confirmation devices 333, 4331, 4332, 4333, 4334. Therefore, since correction of a grain size of the compounded granular body close by a kneading process is carried out, the compounded granular body having the precise coarse grain rate is obtained.

摘要： PURPOSE:To harden a desired area efficiently and perfectly by comprising a stirring device on a girder provided in a transporting base stand travelling for moving on the precedent hardened zone, and hardening the non-processed zone later. CONSTITUTION:A girder 7 projecting to the outside at a certain distance from one end side is mounted in a transporting base stand 4 travelling for moving on the precedent hardened zone to be free to turn up and down, turn around, go in and out and go up and down. A stirring device travelling for moving on the girder 7 is mounted turnably against the girder 7. The non-processed zone 6 adjacent to the precedent hardened zone 1 is hardened later by the stirring device, or this hardening work is repeated in order to harden the non- processed zone 6 while enlarging the hardened zone.

摘要： PURPOSE:To enlarge the moving extent in the shaft line of a plunger by accommodating the reinforcing member of the plunger in the slotted groove of a body, thus extremely thinning the thickness of the body. CONSTITUTION:Depending on the acting force of a plunger, the force applied on the projecting part 12 of a jaw 2, which is generated in holding a workpiece, is separated into the components of a surface pressure load and a bending load. The surface pressure load is received by a wedge member 50 and the bending load is received by a reinforcing member 60. Using such a method as to support the component forces, a jaw part V forming the T-shaped wedge groove of the plunger 4 may receive only a cantilever load. Further, in order to perfectly receive the increased extent of the bending load, which is increased accompanied with strong holding, the reinforcing member 60 is accommodated in a slotted groove 11.

摘要： PURPOSE:To accurately stop and maintain a power transmission element at any position by screwing threaded shaft positioned inside a cylinder to a piston via a ball-screw means and a sealing means. CONSTITUTION:A position near by the blocking covers 12, 13 of a threaded shaft 18 is held by a bearing 19, a threaded shaft portion 182 positioned inside the cylinder 10 of the threaded shaft 18 is screwed to a piston 15 via a ball- screw means 15 and a fluid sealing state between the threaded shaft 18 and the piston 15 is kept via a sealing means 22. Accordingly, a braking device 23 is operated for stopping the threaded shaft 18 to securely hold the displacement of the piston 15 via the engaging force of a screw so that a power transmission element 16 can be forced to be stopped and maintained at a designated position.

摘要： PURPOSE:To enable a work to be fastened stably without inclining a pair of wedges and a jaw by having the wedges operating the jaw in the axial direction of a body toward the position between the supporting wedges. CONSTITUTION:A pair of supporting parts 16 and 16 projecting from each fork end member 13 are supported throughout the longitudinal length of said parts 16 by a body 1 both internally and externally. The operating position of the wedge 14 integrally formed with each of the supporting parts 16 to the wedge groove 10 of a master jaw 9 is to be within the area wherein the supporting members 16 and 16 are held by the body 1. The wedges 14 and 14 are therefore held at both ends thereof and each of the wedges 14 and 14 operates the jaw 9 within the supported area so that the bending moment does not act on both the member 13 apart from the wedges 14 and the jaw 9. As a result, the stable fastening force to a work may be obtained without inclining the fork end members 13 and the master jaw 9.

摘要： PURPOSE:To ease a shock at the time of stopping a piston by providing a flow regulating mechanism on a fluid supply and discharge passage, and connecting the mechanism and a brake to a controller related to a detection signal of a piston position detector. CONSTITUTION:A flow regulating mechanism 8, is provided on the way of a fluid supply and discharge passage 7 for communicating an oil sending direction changeover valve 5 with a check throttle valve 6, and this flow regulation valve 8 and a friction brake 24, are connected to a controller 30 to which a detected signal of a pulse encoder 26 is input. When a piston 17 is to be stopped, therefore, a displacing speed of the piston 17 can be first be lowered by the mechanism 8, and the friction brake 24 can thus be actuated afterward. As a result, it is possible to accurately stop the piston 17 at an arbitrally specified position even the piston is in high-speed displacement and to ease the shock at the time of stopping the piston 17.
