摘要： PROBLEM TO BE SOLVED: To attain the power saving or the prevention of a life from shortening due to the unnecessary operation by interrupting the power source of a device when any operation is not carried out until the power interrupted time which is judged in accordance with the using state of the device, is passed away. SOLUTION: By a system CPU part 50 which is furnished with a table 74a of power-off condition in an inside memory 74, plural power-off times are recorded in accordance with the combination of the informations such as, e.g. whether the optical disk 10 is loaded or not, a disk tray is closed or not, the final operation is the completion of the reproducing operation or not, and so on. When the changing states of the key operation, the close of the disk tray, etc., are detected during the time when the reproducing operation is stopped, the power-off time corresponding to the condition is read out from the table 74a of the power-off condition based on signals from a disk existence detector 71 and a disk open/close detector 72, and set in a time monitoring timer 73, then the count down is performed. When the set time is passed away with the state of no change, the power source is turned off.

摘要： PURPOSE: To enable an operator to grasp the operation state of an operation terminal where operation output is performed by storing an operation terminal in-process data storage means with operation states of operation output by operation terminals, and taking the operation states of operation terminals out of the operation terminal in-process data storage means and displays them on a display device. CONSTITUTION: A plant equipment operation means 25 when taking input/output information out of a plant equipment information storage means 2 at an operation request and performing operation output stores the operation terminal in-process data storage means 21 with the operation state of the operation output by operation terminals. Then a plant equipment operation in-process processing means 26 takes out the operation state of the operation terminal which performs the operation output out of the operation terminal in-process data storage means 21 and displays it on the display device. Consequently, the operator can grasps the operation state of the operation terminal and reduces the burden on the operator.

摘要： PURPOSE: To provide a process controller which can directly estimate the dead time and can compensate the deterioration of stability due to the dead time in on-line or off-line mode even if the dead time of a process serving as a controlled object changes. CONSTITUTION: An identification signal generator e us operated at every fixed time, and an identification signal is applied to a process 8. An identification mechanism 7 calculates dead time Lm of the process 8 and transmission function Gm in on-line/real-time mode based on the application timing of the identification signal and its frequency characteristic and also on the change timing of the output value of the process 8 and its frequency characteristic. Then, the dead time compensation characteristic Gm (1-e L ) of a dead time compensator 5 is updated by the time Lm and the function Gm.

摘要： PURPOSE:To more safely operate an electric power plant and to reduce the burden of an operator by continuing the progress of start/-stop with just once of a condition ignoring operation when any trouble is generated in the start/stop of the electric power plant. CONSTITUTION:A signal input device 2 inputs a plant state amount S1 from a plant 1 and outputs a plant signal S2 required for monitoring the operation of the electric power plant to a state deciding means 3. The state deciding means 3 compares the plant signal S2 with a normal value for monitoring the operation, outputs the conditional trouble item of the plant state as a display signal S7 and displays it on a display 4. When the operator requests the ignorance of conditions, an interactive input means 5 inputs the displayed conditional trouble item as a signal 8 and reports it to a condition ignorance number converting means 6. This condition ignorance number converting means 6 reports the request of condition ignorance to the state deciding means 3 as a signal S10 so that the start/-stop of the electric power plant can be continued.
