Title: Phase synchronizing oscillator
Inventor: MUTO HIROSHI
IPC: H03L7/08
Filed: 1985-09-30
Abstract: PURPOSE:To prevent generation of alarm due to a momentary phase error by providing the 2nd phase comparator circuit generating two logic levels in response to the phase difference between an output signal of a jitter generating circuit and a reference input signal and a signal interruption detecting circuit detecting the intermission of the output signal of the comparator circuit. CONSTITUTION:When a steady phase error of a phase synchronizing oscillator is a predetermined jitter amplitude or below, an output signal f3 of the 2nd phase comparator circuit 5 is a clock signal, and when a steady-state phase error exceeding jitter amplitude is generated, the signal is fixed to a logic level of '0' or '1'. Thus, the output signal f3 of the phase comparator circuit 5 is regarded as a clock signal and supervised by the signal interruption detecting circuit, then whether or not the steady- phase error of the phase synchronizing oscillator exceeds the threshold value decided by the jitter amplitude is detected easily. Further, the momentary phase abnormality such as phase sudden change of a reference input signal is canceled in a short time decided by the transient response characteristic of the phase synchronizing oscillator and the steady-state phase error is restored. Thus, a minute and accurate steady-state phase error is detected easily and the detection threshold value is decided to a duration time of the steady-state error abnormality.

More specifically, an Fe-Cr-Co magnetic alloy having the magnetic characteristic approximately equal to the magnetic characteristic of an ordinary material treated in one stage is obtd. by subjecting the material to the primary aging treatment in two stages in the magnetic field.

Abstract: PURPOSE:To overcome variation in parameter of a controlled system due to nonlinearity depending an input signal, a movement place, and a moving method by supplying a position compensator with an initial value which minimizes a secondary form evaluation function regarding a position deviation and its speed. CONSTITUTION:A measuring means 15 measures the position of a body 1 to be positioned. A speed compensator 16 roughly feeds the object body 1, which is roughly fed to before a target position, at a high speed by controlling the speed of a driving means 14 according to the measurement result of the position measuring means 15. The position compensator 18 positions the object body, roughly fed to before the target position, at the target position under the position control of the driving means 14. A control mode switch 17 switches the control mode from the speed control by the speed compensator 16 to the position control by the position compensator 18. An optimum initial value setting means 19 sets the initial value, which minimizes the secondary evaluation function regarding the deviation signal and its difference signal, in the position compensator 18.
