Abstract: PURPOSE:To judge in real time whether a welding fault exists or not during the welding process with a simple constitution by detecting the height of welding bead based on a detecting signal from a laser distance sensor and judging whether the welding fault exists or not. CONSTITUTION:A computer 9 executes arc welding of a work 1, and together measures the dimension of height of a welding bead 2 with a laser distance sensor 5. The computer 9 records the result measuring the height's dimension of the welding bead 2 separately into a welding starting end part, a welding intermediate part, and a welding finishing part, and judges the upper limit value, the lower limit value separately about them. Then, in a case that the measure value is beyond than the upper value or the lower value, it alarms and stops the welding operation. Further, the computer 9 calculates and records an average value of the height of welding bead 2 about each work 1 or the number beyond the set value from the recorded information and outputs the statistics information about the welding.

Title: Duplicate synchronizing signal generating system
Inventor: MIYAUCHI NAOKI
IPC: H04N5/06
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To prevent a screen image pattern from being shocked due to switching by giving a CF pulse signal from one of duplicate synchronizing signal generators to other synchronizing signal generator so as to make phases of both the signals in matching with each other. SOLUTION: A duplicate synchronizing signal generator 102 (103) is provided with a counter 102-1 (103-1), and both the counters receive a subcarrier in common from a rubidium oscillator 101 and generates a horizontal signal, a vertical signal and a color frame signal and a duplicated master synchronizing signal being a composite signal of them is outputted from respective output sections 102-2, 103-2. Then a phase comparator section 103-3 of the synchronizing signal generator 103 receives a color frame signal outputted from the other synchronizing signal generator 102 and uses it to reset the counter 103-1 for each of the horizontal signal, the vertical signal and the color frame signal of its own station. Thus, even when an output signal is replaced and outputted due to a fault or the like, a shock resulting from unmatched phase is not caused.

Abstract: PROBLEM TO BE SOLVED: To collect effective measure value data that eliminate a time when an electric faulty occurs by performing a differential detection and correcting a differential between a clock of a terminal and a standard clock in central unit or a parent station and correcting the measure value data in accordance with this corrected time. SOLUTION: Value of a pulse input memory 3 is stored in a collected data area when a data collection starting time comes. At this time, a data collection flag sets a flag and stores it in order to show that measure value data are collected. Hereby, at the time of disconnection of power source of a terminal device, the measure data are added to the pulse input memory 3 and, at the same time, a time Toff that stores a current collection time storage memory 5 is stored in a power source disconnection occurrence time memory 2. That is, a time storing process information adapted at the end of the power source disconnection occurrence is made to be a power source disconnection occurrence time.  When a power is supplied, a power interruption occurrence flag is set and at the same time a time difference of Toff -Ton is calculated from the time Ton of a time circuit at the time of power supply, a differential of a clock is detected and corrected.

Abstract: PURPOSE:To prevent bucking of a tubular bumper bound fixed to a damper rod to be contacted against the damper body, by forming projections on the innercircumference of inserting hole of damper rod in the direction to reduce the inner diameter of hole. CONSTITUTION:When fixing a bumper bound 10 to a damper rod 14, a washer 18 and a bolt 16 are previuously fixed to the damper rod 14 then the large diameter section 32 of bumper bound 10 is applied over the damper rod 14. Here, a plurality of projections 34 formed on the large diameter section 32 in the direction to reduce the inner diameter of hole will enlarge the inner diameter at a moment and ride over the washer 18. The stepped section 33 between the small diameter section 30 and the large diameter section 32 will contact against the washer 18. Then, an upper receiving board 22 is fixed onto the spacer 20 to tighten a nut 24 thus to complete assembling. Since the gap between the projection 34 and the outercircumference of damper rod 14 is small, bucking will never occur in the bumper bound 10.
