Title: Removing method for defect cause in stud welding
Inventor: ISHII HIROYUKI
IPC: B23K9/20
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To eliminate causes for disturbing smooth actuation at an early stage, and improve welding work efficiency by detecting a moving volume of a welding gun before the start of welding after presetting the distance for pulling and pushing a stud, and by stopping the welding start action when the movement volume exceeds a setting tolerance. SOLUTION: A stud S is pulled up and pushed before the start of welding, and the movement volume of a welding gun GN is detected by a movement volume detecting circuit MC so as to output it to a welding control device 3. The detected value is compared with the setting value by a CPU of the welding control device 3. When the detected value exceeds the preset movement tolerance, a welding gun smooth movement irregularity is displayed at a display circuit 12 or alarmed to stop the welding start action, resulting in eliminating the irregularity cause.  Further, in the case of welding a material W to be welded after checking the smoothness of actuation, at the time when the main arc period integrating heat volume being calculated based on the main arc voltage detecting gap average value reaches the set standard heat volume, the pushing of the stud S is started so as to compensate the shortage of heat caused by the short circuit.

Title: Measuring device for underwater position of cutter of pump dredger
Inventor: GOTOU SEIICHI
IPC: G01C13/00
Filed: 1984-03-31
Abstract: PURPOSE:To measure the underwater position of the cutter of a pump dredger accurately regardless of the fluctuation of the dredger itself by providing two hydraulic pressure gauges to a ladder which extends out of the dredger at an interval on a straight line which runs through the cutter atop the ladder. CONSTITUTION:Two strain gauge type hydraulic pressure gauges 11 and 12 are fitted to the ladder 2 at the interval l1 on the straight line running through the tip of the cutter 5. The hydraulic pressure gauges 11 and 12 are connected electrically to an arithmetic device. The depth (h) of water of the cutter 5 is calculated from h=h1+(h2-h1)X(l1+ l2)/l1, where h1 and h2 are the depths of water of the hydraulic pressure gauges 11 and 12, l1 is the interval between the hydraulic pressure gauges 11 and 12, and l2 is the distance between the hydraulic pressure gauge 12 and cutter 5. This equation and equations for calculating the depths h1 and h2 of water from detected hydraulic pressure values of the hydraulic pressure gauges 11 and 12 are stored in the arithmetic device previously. Consequently, hydraulic pressure data obtained individually by the hydraulic pressure gauges 11 and 12 during dredging operation are converted by the arithmetic device into the corresponding depths h1 and h2 of water and those are used to calculate the accurate depth (h) of water of the cutter 5 regardless of fluctuation of the pump dredger 1.
