Title: Arm control system
Inventor: TAKANASHI NOBUAKI
IPC: G05B19/42
Filed: 1985-02-28
Abstract: PURPOSE:To select automatically the attitude of an arm by using a ratio of the distance between a target position designated as a point on the operation course of the arm and the axis of the arm to that between the first and the second positions to interpolate the attitude. CONSTITUTION:The position and the attitude of an arm body 6 at a point nearest to an axis Z of the arm 6 are taught and stored preliminarily, and those at a point most distant from the axis Z are taught and stored preliminarily. A target position P is designated, and a distance R between the position P and the axis Z is obtained. The distance R is compared with a distance R1 between a position P1 and the axis Z and a distance R2 between a position P2 and the axis Z, and the target position and the target attitude are obtained to move the arm if R1<=R<=R2 is true. Thus, even when the arm is moved in a wide range, the attitude is automatically selected so as to utilize the moving range of the arm 6.

The second discriminator 14 generates a signal when the machine provides an interpole distance to be likely in an open state in an out-corner part and machining mean voltage reaching a predetermined value. A setter 17 automatically deduces predetermined values of the machining speed and the machining mean voltage to be set from information of an electrical condition of the machining from a control unit 11. While in the finishing, a control unit 13, by the signals of the first and second discriminators 12, 14, controls the machining speed, when it reaches the predetermined value, to be locked so that the machining speed is prevented from increasing to the predetermined value or more. That is, the machine, in which the machining speed is locked to a proper value in an edge part, is prevented from generating an overshoot.

Title: Peak holding circuit
Inventor: TANIMOTO YOSHIO
IPC: H03G3/30
Filed: 1986-02-25
Abstract: PURPOSE:To attain the accurate actuation of a peak holding circuit with low C/N by providing the 1st and 2nd maximum value detecting parts and to avoid such a case where the noise is misunderstood as a unique word UW. CONSTITUTION:The wave detection signal (b) undergoes the A/D conversion by the control signal (e) through an A/D converting circuit 1. This converted signal (b) is supplied to the 1st maximum value detecting part consisting of the 1st signal comparator 2, the 1st signal latch circuit 3 and the 1st arithmetic circuit 4 as well as the 2nd maximum value detecting part consisting of the 2nd signal comparator 5, the 2nd signal latch circuit 6 and the 2nd subtractor circuit 7 respectively. Thus the noise voltage is absorbed by those two maximum value detecting parts even though the signal (e) is sent to the noise by mistake and the noise detecting voltage is larger than the incoming burst signal detecting voltage at that time point. Thus the 2nd maximum value detecting part holding the burst signal detecting voltage is never affected.
