Title: Consumable electrode type arc welding method
Inventor: MUNEZANE YOSHIAKI
IPC: B23K9/127
Filed: 1984-12-19
Abstract: PURPOSE:To prevent the disturbance of welding current owing to a correction operation and to improve the accuracy of profiling follow up in a welding method in which a welding torch is subjected to weaving under the correction of a weld line by the detected welding current or voltage by modifying the period for correcting the weld line. CONSTITUTION:Welding is executed along the corrected weld line while the welding torch is subjected to the weaving under the correction of the weld line in accordance with the detected welding current or welding voltage. The weld line is corrected in the position apart from the right or left end of the above-mentioned weaving. The generation of the disturbance in the welding current is thus obviated and the profiling accuracy is remarkably improved, unlike the conventional control for the correction at the weaving end or right after said end.

Title: Crawler belt tension adjuster
Inventor: NISHIMORI HIROYUKI
IPC: B62D55/30
Filed: 1998-09-07
Abstract: PROBLEM TO BE SOLVED: To prevent relative displacement or inclination between a yoke and a tension adjusting cylinder by loads acting on an idler wheel, and facilitate their installation. SOLUTION: A yoke 16 for supporting an idler wheel 9 and a tension adjusting cylinder 17 are integrally interconnected via a quick-disconnection coupling 26. Both yoke 16 and tension adjusting cylinder 17 are thus prevented from jackknifing to hold the idler wheel 9 supported stably for a longer period even when it receives vertical and horizontal loads in addition to back-and-forth loads. For appreciably improved assembly, both yoke 16 and tension adjusting cylinder 17 are also allowed to be integrally interconnected via the quick- disconnection coupling 26 within a side frame 3 even after they are individually installed in the side frame 3.

Title: Phase synchronization receiving device
Inventor: MAEKAWA KATSUNORI
IPC: H04B7/26
Filed: 1985-11-29
Abstract: PURPOSE:To secure the coincidence between an optimum reception frequency and a reception carrier frequency by using the output of a phase detector for tracking of reception carrier wave or a phase detector for phase comparison of local oscillation signal to the input of the frequency control signal of a frequency variable local oscillator based on the reception state of the reception carrier wave. CONSTITUTION:The initial synchronization can be caught by sweeping a reception signal frequency or a local oscillation signal frequency in case the reception signal level is high enough to secure the synchronization of a receiver 13a or 13b. If the receiver 13a, for example, is synchronous with the reception signal, the frequency control signal input of a local oscillator 8b of the asynchronous receiver 13b is changed to the output of a phase detector 9 which performs comparison of the phases of the local oscillation signals by a switch controller 11. As a result, the coincidence is secured between the local oscillation frequencies of both receivers 13a and 13b. Then the optimum reception frequency of the asynchronous receiver 13b is coincident with the carrier wave frequency of the reception signal.
