摘要： PURPOSE:To obtain a satisfactory response even when a dynamic characteristic of a kinetic machine system being a control object by generating a control input for shifting a deviation between a controlled variable and a target value to a stable phase face in accordance with a non-linear control law. CONSTITUTION:By an arithmetic means 12, a deviation (s) from a designated stable phase face is operated from a deviation (e) between a controlled variable (x) of a control object and a target value (r), and in an adaptive means 13, a parameter thetaof the control object is identified so that the deviation (e) between the controlled variable (x) of the control object and the target value (r) becomes minimum by using a result of its operation. In a controller 14, a control input tau is generated so as to shift the deviation (e) between the target value (r) and the controlled variable (x) to a designated stable phase face by a non-linear control law by using the deviation (s) obtained by the arithmetic means 12 and the parameter theta identified by the adaptive means 13. The non-linear control law used in this case has an integral function for setting the deviation (e) between the controlled variable (x) in a stationary state and the target value (r) to '0'. In such a way, even when a dynamic characteristic of a kinetic machine system being the control object is varied, and error is compensated and a stable response is obtained.

摘要： PROBLEM TO BE SOLVED: To surely chuck the journal of a roller and to easily and accurately set the advancing amount of a pressing rod for a chuck even in the case of the roller having the different dimension of the journal by advancing the pressing rod together with a cylinder for a mask and pressing the leading edge of the pressing rod to the end face of the journal. SOLUTION: Cylinders for a chuck 26 and 26A and the cylinders for a mask 23 and 23A are respectively independently actuated. Namely, the advancing amount of the cylinders 26 and 26A can be set without considering an amount by which barrels for a mask 21 and 21A should be advanced at all. The cylinders 26 and 26A have only to be positioned at positions where distances between the end face of the journal 2 and the leading edges of the pressing rods for a chuck 15 and 16 are a little shorter than the stroke length of the cylinders 26 and 26A. Therefore, the journal 2 projected from the roller 1 is covered by advancing the rods 15 and 16 by an appropriate amount by using the cylinders 23 and 23A.

摘要： PURPOSE:To obtain a device which automatically inserts a fluorocarbon resin tube over a guide rod and prevents the slip-off of a claw from the tube when a tube fold-back process is carried out. CONSTITUTION:An end part of a flat fluorocarbon resin tube 4 is opened by a vacuum pad 23. A guide rod 5 is advanced to be automatically inserted into the open end part. In this manner, a production time is shortened and a manhour is reduced, whereby a production efficiency can be improved. In addition, a slip-off preventing air cylinder is provided opposedly to a claw to prevent the slip-off of the claw from the extended-diameter end part of the tube in a tube fold-back process. Therefore, the tube-fold back process can be smoothly conducted.

摘要： PURPOSE:To enhance the quality of the surface state of a roller when the roller taken out of a baking furnace is quenched. CONSTITUTION:In such a state that the upper journal part 3 of a roller 1 is grasped and the other journal part 3 thereof is turned downwardly, the roller 1 is dipped in a cooling liquid 50. When the lower journal part 3 of the roller 1 is dipped in the cooling liquid 50, the falling of the roller 1 is stopped for several sec to lower the temp. of the journal part 3 a little. Thereafter, when the whole of the roller 1 is dipped in the cooling liquid 50, no irregular patterns are generated on the surface of the roller 1 and the roller 1 is smoothly finished.

摘要： PURPOSE:To prevent one end of a tube from generating wrinkle and to automate a tube folding process by providing an elastic retreating part, which elastically retreats by bringing it into contact with a guide rod on the apex of a tube inserting rod. CONSTITUTION:A tube inserting rod 25 inserted in a tube 2 is placed in a pipe 1 and when a guide rod 32 is brought into contact with the apex of this inserting rod 25, only the contact part 31 which is a part, of the tube inserting rod 25, is elastically retreated by the pushing pressure of the guide rod 32. Therefore, as the guide rod 32 is surely inserted in the end part of the tube 2, the end part of the tube 2 can be folded back to the end part of the pipe 1 by means of packs 33 and 34. In addition, as the tube inserting rod 25 itself is not retreated, no wrinkle is generated on the other end of the tube 2.

摘要： PURPOSE:To properly cool a chuck in such a case that a roller is supported by the chuck through a journal part and to bake the roller under temp. conditions uniform and stable as a whole. CONSTITUTION:An inside plug 21 is preliminarily fitted in the hollow part 19 of a chuck 15. When the inside plug 21 is provided to the deep part of the hollow part 19, cooling water is circulated to the deep part of the chuck 15 to cool the chuck. When the inside plug 21 is moved toward the inlet of the hollow part 19, cooling water is circulated only in the part close to the inlet. Therefore, when the position of the inside plug 21 is regulated, the cooling effect of the chuck 15 can be adjusted to the optimum value.

摘要： PROBLEM TO BE SOLVED: To provide a measuring apparatus by which an external size can be measured automatically and precisely by a method wherein one pair of contour measuring sensors which are arranged so as to be faced on parallel side faces of a force-cooled conductor are moved in parallel on the side faces. SOLUTION: Drive parts 7B, 11B at actuators 7, 11 for sensor movement are operated by a control part 13. Movement frames 6, 10 are positioned in prescribed positions. One pair of external-shape measuring sensors 5A, 5B are positioned in upper parts of side faces 1A, 1B of a force-cooled conductor 1. Sensors 9A, 9B are positioned at ends, on one side, of side faces 1C, 1D. Then, by a reflected laser beam, the sensors 5A, 5B measure a distance at the upper parts of the side faces 1A, 1B, and the sensors 9A, 9B measure a distance at the ends on one side of the side faces 1C, 1D. On the basis of both measured data, the control part 13 computes a width at the upper parts of the side faces 1A, 1B and a width at the ends on one side of the side faces 1C, 1D so as to be stored. Then, the drive parts 7B, 11B are operated, one pair of face sensors are moved in parallel little by little, and a central width and a lower width between the side faces 1A, 1B as well as a central width and a width on the other end, between the side faces 1C, 1D are computed so as to be stored. This operation is repeated whenever the conductor 1 is run by 10m, and respective measured data are printed 15.
