Title: Regulator
Inventor: HAMANO MINORU
IPC: G05B13/00
Filed: 1981-10-17
Abstract: PURPOSE:To detect parameters regarding characteristics of a system to be controlled from a limit cycle when the system to be controlled is controlled to turn on and off, and to calculate and set the best value of a PID constant, by using the parameters. CONSTITUTION:When an operation mode is specified through a key input part 16. a control part 15 performs control so that a PID regulation part 11 operates in the specified mode. Under the control of a control part 15, the on-off regulation part 11 regulates a manipulated variable Y(t) between two specific values so that the deviation 8(t) of an arithmetic expression is canceled. A constant arithmetic part 12 operates under the control of the control part 15 only during the operation of the on-off regulation part 11 to observes the limit cycle of a controlled variable theta(t) indirectly by the deviation Z(t), and then calculates the best value of a PID constant on the basis of the observation result. After the calculation of the PID constant is completed, that is reported to the control part 15 from the constant arithmetic part 12. On receiving this report, the control  part 15 stores the constant value in an address of a memory 14 corresponding  to the operation mode and then starts the PID regulation part 10.

Title: Cnc screen switching system
Inventor: TANAKA KUNIO
IPC: G05B19/4069
Filed: 1990-06-26
Abstract: PURPOSE:To simplify the operation of a numerical controller CNC by registering a composite function key into a memory to secure the same operations as plural keys and then operating this composite function key to switch the displayed screens in the same way as plural keys. CONSTITUTION:The definition is carried out to replace the keys K8, K6 and K1 with another key KX. That is, KX = K8 + K6 + K1 is defined so that a trace screen 5 is switched to a ladder screen 1 with push of the key KX in the same function secured with push of those keys K8, K6 and K1. In fact the screen 5 is switched to a diagnostic screen 4 and then to an initial screen 2 and the screen 1 respectively. However these switch actions are carried out in an instant and therefore it seems that the screen 5 is switched directly to the screen 1. On the contrary, the screen 1 can be switched to the screen 5 with definition of KY = K2 + K5 + K7. Thus the operation of a CNC is simplified.
