摘要： PROBLEM TO BE SOLVED: To provide an apparatus for oscillating a mold in a continuous casting facilities with which control corresponding to each movement characteristic of a controlled object can be performed by estimating the state quantity of the control object without detecting the state quantity of the mold. SOLUTION: This apparatus contains: a hydraulic cylinder 27 for displacing a mold 28 in a reciprocating manner; a servo-valve 26 for controlling the supply of hydraulic oil into a hydraulic cylinder; a compensator 24 for giving the servo- valve a servo command value vc; a stroke sensor 29 for detecting the displacement xs of the hydraulic cylinder; and a state observing instrument 25 for giving an estimated state quantity xc by estimating the state quantity showing the states of the mold and the hydraulic cylinder on the basis of the displacement xs of the hydraulic cylinder and the servo command value vc. In this way, a desired oscillation can be given to the mold while eliminating the effect of a characteristic frequency by performing optimum control on the basis of the estimated state quantity xc without detecting the state quantity of the mold.

摘要： PROBLEM TO BE SOLVED: To solve the problem of inconvenience with an earthquake control system due to the delay of control of a host computer in a real-time control system for an active seismic control structure, or decrease in system reliability due to simplification of system management functions. SOLUTION: The functions of a host computer in a traditional system are shared by a control computer for system management and an arithmetic computer for performing control arithmetic for seismic control. The arithmetic computer originates a control signal for seismic control in real time based on a signal of a sensor for detecting disturbance or the vibration of a structure, and transmits it to the controller of an seismic control system via each communication computer. The control computer receives signals of sensors or the like for detecting the condition of the seismic control system, monitors the condition of the system, and manages the entire system as to measurements as required, reports corresponding to troubles, fail-safe measures and the like.

摘要： PURPOSE:To obtain the electric joy stick device which dispenses with its mechanical adjustment and has high reliability. CONSTITUTION:An analog voltage VP from a potentiometer 70 is converted to a digital signal SP of 10 bits by an A/D converter 53. A CPU 54 converts it to a digital signal SC of 8 bits by using a conversion coefficient stored in a ROM 55. By this conversion, influence of a variance of magneto-resistance effect elements 71, 72 and an amplifier 52 can be eliminated.

摘要： PURPOSE:To enhance an attendance feel so that an operator has the real feel of running by generating the signals which relatively associate an oscillation control signal, video signal and acoustic signal. CONSTITUTION:A signal generating means 28 has the constitution resembling to the constitution of a video tape recording/reproducing device and is recorded with the video signal and the oscillation control signal and acoustic signal corresponding to the running state in the recording region intersected with the longitudinal direction of a magnetic tape. The video signal from the means 28 is applied to a video display means 34 and is displayed. The sounds by the acoustic signal are generated by a speaker 35. The oscillation control signal from the means 28 is applied to a control panel 43 which leads the signals for the vertical positions of a piston rod 26 and a rear wheel 4 by the position signal for the rear wheel from a detector 38 to a line 39. A subtraction circuit 37 subtracts the lines 36, 39 and applies the results thereof to a double action cylinder 14 via a proportional integration action part 41 and an electro-hydraulic conversion part 42 so that the oscillation and the reference position of the oscillation are applied to the rear wheel 4. The driver on a seat 5 is thus able to view the video of the means 34, to hear the sounds from the speaker 35 and to have the real feel of the running condition by the rear wheel 4, thus having the attendance feel.
