Title: Controlling mthod of synchronized driving system
Inventor: SASAKI YOSHINARI
IPC: G05B19/19
Filed: 1984-02-14
Abstract: PURPOSE:To reduce an error and to attain rapid coincidence by inputting an objective value of a servo system to the 1st and 2nd servo systems respecively and inputting the difference of both outputs to the 2nd servo system through a compensating system. CONSTITUTION:An objective value theta* of a synchronized driving system is inputted to a master servo system 11 to be the 1st servo system and a slave servo system 12 to be the 2nd servo system. The deviation between the output thetaM1 of the master servo system 11 and the output thetaM2 of the slave servo system 12 is inputted to the compensating system 13 and its output Oc is inputted to the slave servo system 12. Consequently, the slave servo system 12 is serially compensated by regarding the output thetaM1 of the master servo system as its objective value and feedforward control based upon the real objective value theta* to be followed by the output thetaM1 of the master servo system 11 is executed. Both the servo systems themselves also constitute a feedback system.

Title: Producing method of prom for programmable controller
Inventor: KUDO KAZUHIKO
IPC: G05B19/05
Filed: 1992-02-13
Abstract: PURPOSE:To provide a producing method of PROM for PC(programmable con troller) in order to obtain the PC of a small capacity memory and to prevent the breakage of the PC contents even in an operating environment. CONSTITUTION:A normal user program is stored in a PROM together with an execution program obtained by converting the user program into the machine words. When the PROM is loaded into a PC and the sequence control is carried out, a CPU can directly carry out the execution program of machine words stored in the PROM. Therefore the operational processing is quickly performed. Then the execution program is stored in the PROM not in a PC memory and therefore the capacity of the PC memory can be reduced. Thus a user can use an expensive PC. Furthermore the user program and its execution program are written in the PROM for which the contents of these programs are not easily broken even in an inferior operating environment. In such a constitution, a PC performing a stable operation is provided for a user.
