    摘要： A silicon single crystal rod (24) is pulled from a silicon melt (13) made molten by a heater (17), and a change in diameter of the silicon single crystal rod every predetermined time is fed back to a pulling speed of the silicon single crystal rod and a temperature of the heater, thereby controlling a diameter of the silicon single crystal rod. A PID control in which a PID constant is changed on a plurality of stages is applied to a method which controls the pulling speed of the silicon single crystal rod so that the silicon single crystal rod has a target diameter and a method which controls a heater temperature so that the silicon single crystal rod has the target temperature. A set pulling speed for the silicon single crystal rod is set so that V/G becomes constant, and an actual pulling speed is accurately controlled so as to match with the set pulling speed, thereby suppressing a fluctuation in diameter of the single crystal rod.

    摘要： Screen data is generated by a screen generating processor (74) of a control host computer (7) and transmitted to a programmable display apparatus (5). In accordance with the screen data, the programmable display apparatus (5) inquires a PLC (3) or the like about a state of a device (21), so as to update the display or transmit a control instruction depending on an input result. On the other hand, a control host computer (7) has a public server section (77) to transmit to a client apparatus (9) via the Internet an applet, which is generated by a compiler (76) compiling the screen data. The client apparatus (9) executes the applet to transmit to the public server section (77) an or the control instruction inquiry similar to those the programmable display apparatus (5) makes. In this way, the display is updated in accordance with a response. This realizes a control system, which allows a display content of the programmable display apparatus (5) to be remotely checked from a remote area remote from the programmable display apparatus (5), without newly generating a display screen.
