Title: Operation state controlling device for machine tool
Inventor: KUMAGAI YOSHINORI

Filed: 1985-02-18
Abstract: PURPOSE:To make power disconnection in a numerical control device and circuit trouble between a central processing unit and the N/C device clearly distingishable, by inputting a power making signal of the N/C device into the central processing unit via a contact interface circuit. CONSTITUTION:A line control unit 1 delivers a signal between a character display board 3 of a numerical control device 2 and itself via a circuit 15, and inputs a power making signal via each of contact interface circuits 12 and 14, but in case of on-time, collects operation conditions via an N/C interface circuit 5 and thereby counts cumulative time according to the operation conditions. On the other hand, when an operator makes sure of no operation there and cuts power source, an interval between the line control unit 1 and the N/C device 2 comes to circuit disconnection whereby the former suspends the collection of operation conditions via the N/C interface circuit 5, and sets the operation conditions forcedly to stoppage. In addition, when a central processing unit 3 comes to disconnection due to trouble in both N/C and upper interface circuits 5 and 10, the circuit 15, etc., controls the N/C device as trouble in its operation condition.

Title: Input signal level detector
Inventor: SAKASHITA HIDEO
IPC: G01R19/165
Filed: 1978-03-16
Abstract: PURPOSE: To accurately detect the levels of input signals continually, by compensating the action of a comparator and a flip-flop by changing the currents of current control circuits when line voltage alters.  
     CONSTITUTION: When voltage not more than detecting voltage is applied to input A, a comparator 4 emits output, and inverts a flip-flop 5. Since output is issued from a comparator 6 by the output of the flip-flop 5, the flip-flop 5 instantaneously returns, thus emitting pulse-like output from the flip-flop 5. When line voltage varies, the currents of current control circuits 8, 9 change, and the motion of the comparator 4 and the flip-flop 5 is compensated.
