Title: Printer
Inventor: SATO TAKASHI
IPC: B41J17/36
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To simplify a control process and thus lessen loads of control means by holding in a positive state a detecting signal to be outputted at detection where the cycle exceeds a predetermined cycle by inputting a ribbon traveling signal, and causing substantially detecting operation to be null as a state signal is in a non-positive state. SOLUTION: A multivibrator 8 is activated by the rising edge of a ribbon traveling signal Sr outputted from an optical sensor 6, and outputs a pulse signal becoming effective for only a predetermined period of time. The multivibrator 8 and latch 10 constitutes a cycle detecting means 11 for holding in a positive state a detecting signal to be outputted to a control means 7 as the cycle of the ribbon traveling signal Sr is detected that it exceeds a predetermined cycle. An AND gate 9 forms null means for substantially nullifying the detecting operation of the cycle detecting means 11 as a state signal Sm is in an ineffective period. In this manner, the control process can be simplified, and thereby loads of the control means can be reduced.

Abstract: PURPOSE:To control strictly the liquid level of the molten steel in a casting mold and to perform continuous casting with high quality, by providing a controller for emergency use separately from a PID controller which controls automatically the liquid level of the molten steel in the mold and suppressing the excessive fluctuation in the liquid level. CONSTITUTION:When a liquid level detector 8 detects the liquid level of the molten steel in a casting mold 1, said detector inputs the signal thereof to a PID controller 10 via a filter 9. The controller 10 calculates a control signal from the deviation between the set value of the liquid level of the molten steel and the detection signal and feeds said signal to a servocontrol amplifier 11. Then a servocontrol valve 12 is driven to actuate a hydraulic cylinder 12, thereby controlling the opening of a flow rate control valve 6. A controller 14 for emergency use is provided in parallel with the controller 10. The controller 14 adds the control signal output for emergency to the control signal of the controller 10 when the liquid level of the molten steel exceeds a prescribed fluctuating width and the valve 6 is controlled by said signal, whereby the excessive fluctuation thereof is suppressed.
