摘要： PURPOSE:To control uniformly, taking account of actual load in a load limiter control device for a turbine applied to the load-frequency control of a nuclear power plant or the like. CONSTITUTION:The rotating speed 10 of a generator is inputted into an ALR (automatic load control device) 25, and a speed governing signal 19a is outputted from a speed governing arithmetic part 19. The speed governing signal 19a is inputted to a speed governing feedforward arithmetic part 22, and its output is phase-compensated by a turbine phase compensator 23 so as to be outputted as a speed governing compensation signal 22a. An AFC signal 8 is inputted into a load fluctuation width computing part 20, and its output 20a and the output set value 9 are added. The deviation between the added value and generator output 7 is obtained and phase-compensated by a turbine phase compensator 21 so as to become a set signal 9c. The set signal 9c is added to the signal 22a to control a load limiter 13. Because of controlling by the rotating speed 10 along with the AFC signal 8, load can be correctly limited to the set fluctuation width, taking account of actual load.

摘要： PROBLEM TO BE SOLVED: To increase a rate of operation and enhance forging quality. SOLUTION: A flywheel driving mechanism 10 normally rotates a flywheel 12. Making a clutch shoe 14 a clutch ON state transmits the torque of the flywheel 12 to a screw shaft 2. Normally rotating the screw shaft 2 lowers a nut 3 threadedly engaged with the screw shaft 2 to lower a metal mold 7 toward a metal mold 9 for machining. After completing the machining, the clutch shoe 14 is put in a clutch OFF state. A hydraulic cylinder advances the rack 202a of a screw reverse rotating mechanism 200. Thus, a pinion 201 is reversely rotated to reversely rotate the screw shaft 2, and the nut 3 is raised.
