Abstract: PURPOSE: To eliminate the unbalance of the lives of pumps, by equilizing the operating time of each pump by mounting a memory portion for memorizing the number of a pump first started and the number of a pump last started.  
     CONSTITUTION: Flow rate is measured by means of a detecting portion 1, the number of pumps to be operated corresponding to flow rate is decided by means of a number deciding portion 2 and the number of pumps presently being operated and the number of operating pumps decided are compared by means of an increase and decrease deciding portion 3. When both number disagree, pumps are increased or decreased, and a control signal is put out from an output portion 4.

IPC: B23K9/127
Filed: 1992-02-07
Abstract: PURPOSE:To shorten the time required for sensing and analysis by performing the sensing and the analysis of a gap from the other side of a pair of materials to be welded, one position of which is known. CONSTITUTION:When the gap between works (materials to be welded) 1A and 1B is detected, the sensing with a position sensor 2 is always started from the side of the work 1B, whose position is unknown. Namely, the sensing operation along a detecting line is started from the left side. The detected data are obtained with the optical position sensor 2. The analysis of the gap based on these data is sequentially performed from the side of the work 1B. When the position data of a shoulder part of the work 1B, whose position is unknown, can be detected, the gap between the works 1A and 1B can be immediately computed and detected because the position of the work 1A is known.
