Filed: 1991-08-12
Abstract: PURPOSE:To easily match controlled objects by controlling a control object of its own station at a succeeding time so that the relative error between the control object subject to filtering and its own control object is eliminated. CONSTITUTION:A communication means is provided between adjacent nodes, each node sends its own control object, and a node receiving the control object from an adjacent station applies being spatial filtering Fs or time filtering Ft to the control object of the adjacent station and controls the control object of its own station at a succeeding time so that the relative error between the control object subjected to filtering and its own control object is eliminated. Thus, the information relating to the control object is sent and received between its own node and a node in the vicinity of its own node to find out a relative error, then the relative error with respect to the control object at least in the vicinity of its own node is eliminated without provision of a special control station.

Title: Method and apparatus for cold pilger rolling
Inventor: KIUCHI MANABU
IPC: B21B21/00
Filed: 1986-09-29
Abstract: PURPOSE:To prevent the exfoliation and crack of rolling roll surfaces and to improve productivity by exerting tensile force to a pipe material under rolling in the longitudinal direction thereof to decrease rolling down force. CONSTITUTION:An oil pressure is applied to a chuck 11 of a stock pipe holder 10 and a chuck 16 of a gripping mechanism 14, respectively, when a sequence controller 25 operates to supply a control signal to a hydraulic controller 20. The chuck 11 closes to grip the entire circumference of the stock pipe securely, thereby fixing and holding the same. The chuck 16 closes as well to grip the entire circumference of the product pipe 4 securely and to engage integrally with the product pipe 4. The hydraulic controller 20 supplies the pressure oil to a cylinder 15 to retract the cylinder by the prescribed tensile force, thereby exerting the tensile force in an arrow A direction to the gripping mechanism 14. On the other hand, rolling rolls 1, 1 rotate forward in an arrow C direction while moving in the arrow A direction by a prescribed distance to roll the stock pipe. Since the product pipe 4 is thereby kept pulled in the arrow A direction, the compressing force on the stock pipe by the rolling rolls 1, 1' is decreased.

IPC: B05B7/12
Filed: 1985-10-16
Abstract: PURPOSE:To control the flow quantity of fuel oil to a wide range and to enhance combustibity by increasing the flow quantity ratio of the fuel oil, in a flow variable nozzle having a jet orifice, a vortex chamber, a communication hole and a piston, by providing a specific inflow limiting means. CONSTITUTION:When the flow quantity of fuel oil is increased in a flow variable nozzle, a piston 20 is moved to a direction spaced apart from a jet orifice 6 and the opening area of an outflow port 14 and the volume of a vortex chamber 12 are enlarged and flow coefficient is enhanced to increase the flow quantity of fuel oil. When the flow quantity of the fuel oil is reduced, the piston 20 is moved to the side of the jet orifice 6 and flow coefficient is lowered to reduce the flow quantity of the fuel oil. In this mechanism, a fin part 22 is provided to the piston 20 as a flow limit means. Hereupon, when the fuel oil flows in the vortex chamber 12 from a communication port 16, the fin part 22 closes the unnecessary part of the communication hole 16. Therefore, the speed component is the axial direction is not generated and the fuel oil surely flows in the vortex chamber 12 in the axially orthogonal direction of the revolving stream formed in the chamber 12 and the change in flow quantity approaches a theoretical value. As a result, combustibility is enhanced.
