Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To select optionally a saving action for preventing any interference by arranging a means to turn optionally ON/OFF the saving action to be taken place for another axis so that no action for an axis causes any interference. SOLUTION: The entries by the operation panel 40 are sent to the CPU 31 signaling any command to the drive unit 33 via the D/A converters 32 for actions at each axis to drive the driving motors 34 of each axial direction to have each axis act toward each direction.

Title: Synchronization detecting circuit
Inventor: YASUE HIDETAKA
IPC: G11B20/10
Filed: 1989-02-03
Abstract: PURPOSE:To contrive the decrease of generation of an error by detecting a synchronous signal inputted first to a synchronization protecting circuit with a majority synchronization detecting circuit, and also, checking whether a first synchronous signal is correct or not even with respect to the number of times of continuation of a synchronous error. CONSTITUTION:First of all, synchronous signals c-1, c-2 are detected by synchronization detecting parts B 12, A 11, and thereafter, the signal c-1 is inputted to a synchronization detecting circuit 20, and a window pulse (b) for deciding whether the next signal c-2 is correct or not is generated. On the other hand, when the signal c-1 and the signal c-2 are detected simultaneously in a majority logic circuit 16, it is decided that the signal c-1 is detected at a normal timing. Subsequently, the signal c-1 is inputted to a various timing generator 5, and data is written in a memory. Thereafter, the operation of the circuit 16 is stopped with a mode switching circuit 30, and when continuous errors exceeding the prescribed number of times are detected in a continuous error detector 24, the mode is returned to a first mode again. In such a manner, the generation of an error caused by a fact that a synchronous signal detected erroneously is used as a first synchronous signal is decreased.
