Title: Wire feed controller for automatic welding
Inventor: MATSUMOTO KATSUMITSU
IPC: B23K9/12
Filed: 1977-09-14
Abstract: PURPOSE: The titled controller which can easily, accurately carry out the stabilization of welding, by varying the wire feed speed following to fluctuation of the input power source voltage.  
     CONSTITUTION: When the wire feed speed F changes by ΔF, as a result of change  in the input power source voltage, that is, the value of V 1  proportionally changes by ΔV 1 , the changing rate of the wire feed speed is formulated to the formula II using V 2 ' and β which are included in the formulaI. The formula II becomes similar to the formulaIwhen β≈1, that is, the wire feed speed is large, and then, the changing rate is decided by the constant-voltage value V 3  of the constant-voltage passive element 7; whereas, when β=0, that is, the wire feed speed is small, the changing rate is decided by the constant-voltage value V 4  of the constant-voltage passive element 7'. Accordingly, by properly selecting values of V 3  and V 4 , the changing rate of the wire feed speed, with the fluctuation of the input power source voltage, can be regulated for the high speed feeding zone and the low speed feeding zone independently of each other.

Abstract: PURPOSE:To fetch exactly an ID signal at the time of a high speed reproduction, by executing the phase control of the travel motion of a magnetic tape, based on a beat signal which has been brought to sampling by a sample holding circuit, at the time of the high speed reproduction. CONSTITUTION:At the time of a high speed reproduction, the reproduction is executed so that a magnetic head crosses a recording track 15, as indicated with an arrow 14, therefore, pilot signals f1-f4 from a fetching circuit 7 become signals of a regular level variation. Both beat signals from a beat signal fetching circuit 8 of this time are brought to sample holding in response to a sampling signal and a phase control is executed. Accordingly, the phase control can be executed by a voltage which has been brought to sample holding by a sample holding circuit 13. Also, the sampling signal corresponds to a timing of reproduction of an ID signal, namely, a timing for fetching the ID signal, therefore, the ID signal is fetched by the maximum level of a reproducing output. In this way, the ID signal of the time of a high speed reproduction can be fetched exactly.
