摘要： PURPOSE:To perform the most effective filtration operation suitable for the property of original liquid by inserting an elastic body whose sectional form is easily changed between adjacent filter plate bodies constituting a filter chamber, installing a moving device for axially driving the filter plate bodies and performing the proper setting of the thickness of dehydrated cake with the same machine. CONSTITUTION:Elastic bodies 2 whose sectional form is easily changed are successively fitted in filter plate bodies 3 spreading filter cloth 4 in the inner side surface part where a recessed part 31 including the elastic body 2 is provided on the outer periphery of one side surface and a projected part 32 which can be fitted with a play to the adjacent recessed part 31 is provided on the outer periphery of the other side surface, and a moving device 6 for moving a moving frame 5 which comes into contact with the end part of a group of filter chambers 10 on the opposite side of a fixed frame 1 and bears filter reaction force in the thickness direction of the filter chamber 7 is installed. Consequently, the thickness of the filter chamber formed, that is, the thickness of the dehydrated cake, is properly changed and by controlling the moving quantity of the moving frame before the start of a filtration process, the proper setting of the thickness of the filter chamber on which the filter performance is most dependent is possible with the same machine.

摘要： PURPOSE:To improve the life of filter cloths due to the compression damage between filter frames as compared with a conventional method. CONSTITUTION:The pressing force of filter plates is changed corresponding to filtering pressure changed during filtering to always suppress the compression force of the filter frames to a definite range. When the filtering pressure during filtering falls within a short time and rises, the pressing force of the filter plates is not allowed to fall and the filtering pressure again rises to become larger than the filtering pressure before the falling of the filtering pressure to increase the pressing force of the filter plates. The pressing force of the filter plates is increased over a multistage to be controlled so as to always become larger than the reaction force due to filtering pressure. By this constitution, the life of filter cloths is extended to obtain excellent effect such as the reduction of maintenance work or the enhancement of operation efficiency. This method is also effective for reduction of the maintenance cost of filter cloths.

摘要： PURPOSE:To improve working environment through such a work as removing burr on a bar type material with a cutter, by mounting a cutter, profiling roller, switching lever provided with an eccentric boss with lever and an eccentric boss drive gear etc. on a rack moving along the bar type material. CONSTITUTION:A device is operated by closing a switching lever 22 to bring a profiling roller 3 in contact with the surface of a bar type material 1. In this time, relativity between a cutter 2 and a profiling roller 3 is automatically adjusted by making a fine relative rotation of an eccentric boss 9 with a lever in response to an opening angle of the switching lever 22 corresponding to the outer diameter of the bar type material 1. That is, a sector gear 17 is fixed to a moving rack 16 and engaged with a pinion 18 with a lever, and a connecting rod 21 and the eccentric boss 9 with lever are connected thereto to perform adjustment. By this construction, the moving rack 16 is moved with a hydraulic cylinder 33 to remove burr on the surface of the bar type material 1 and working environment is improved.

摘要： PURPOSE: To easily obtain a crushed material with a grain size distribution suited to use by arranging a pair of rotors each equipped with a plurality of plates in a mutually opposite direction and variably in the number of rotation, in the interior of a casing with a lower discharge port, and at the same time, arranging a screen along the lower surface of the rotors. CONSTITUTION: A pair of rotors 7 each with a plurality of plates 9 are arranged in a mutually opposite direction and variably in the number of rotation, in both upper and lower parts of a casing 2, and at the same time, a screen 8 is arranged at a specified interval along the lower surface of the rotors 7 and in such a manner that the screen can be replaced. The screen 8 has a sieve mesh which varies according to use. When using this dehydrated cake crushing device, a dehydrated cake 13 is charged into the charge port of an upper hopper 1, then drops into a crushing chamber 6, and is crushed by collision between the plates 9 of two rotors 7 which rotate reversely to each other at a high speed. After the crushing, the dehydrated cake is discharged as crushed dehydrated cake 14 from the discharge port of a lower hopper 4, after passing through the screen 8.

摘要： PURPOSE:To prevent a flexible elastic diaphragm from getting worn, scratched, and from pinching foreign matter due to contact of the diaphragm with an inner wall of a container and an inner supporting body by providing the flexible elastic diaphragm in a force feeding device. CONSTITUTION:A flexible elastic diaphragm 7 is positioned between an outer tube 6 and an end flange 9 to provide a pressurizing chamber 13 on the upper side and a chamber to be pressurized 14 on the lower side. Since pressure by fluid is distributed evenly on the flexible elastic diaphragm 7, the diaphragm 7 is deformed without offset when it is expanded and, therefore, it is not made in contact with the outer tube 6 even if a buoyancy acts on the diaphragm 7.

摘要： PURPOSE:To accurately cope with each deviation and accumulated errors of the deviation of the joining surface in the longitudinal direction of materials to be welded by making a welding torch freely movable three-dimensionally in the vertical, horizontal and orthogonal directions. CONSTITUTION:In case the welding torch 1 is moved in the longitudinal direction of the materials to be welded, a spline shaft 20 is rotated and a rotational external screw shaft 18 is rotated via bevel gears 21 and 22 and a movable carriage 13 in the longitudinal direction and the welding torch 1 provided to the carriage 13 are moved. Furthermore, in case the welding torch 1 is moved in the cross direction of the materials to be welded, the rotational external screw shaft is rotated and a movable carriage 27 in the cross direction is moved to the cross direction of the materials to be welded, by which the welding torch 1 is also moved with the movable carriage 13 in the longitudinal direction mounted on the top of the carriage 27. Further, in case the torch 1 is allowed to ascend and descend, a sprocket 40 inserted in a spline shaft 50 is rotated and an ascending and descending block 5 is operated to ascend and descend via chains 41 and 6 and the torch 1 is allowed to ascend and descend vertically.

摘要： PURPOSE:To raise the interference allowance setting accuracy for steel tube leg couplers by forming a main inverse shoulder portion and a second stage shoulder portion on a coupled face between the pin and box of the steel tube leg coupler connecting the pin and the box. CONSTITUTION:A main torque shoulder 11 receives a screw reaction by the clamping of a screw 18, and seal faces 11a and 11b on a pin and box sides undergo an elastic deformation by a reaction. A ring 19 for addible seal serves as a secondary seal for back-up purpose in case where a leakage in the seal of the main torque shoulder 11 is generated by any chance. A second stage torque shoulder 17 is set such that the main shoulder 11 is touched after further clamping when clamped during the manufacture of coupler. An interference allowance setting accuracy and the clamping torque accuracy of the torque shoulder on the sea face can thus be raised, control on the interference allowance can be made easier, and an over-clamping can be prevented.
