Title: Method for improving fatigue strength of fillet welding joint
Inventor: SETO KOJI
IPC: B23K31/00
Filed: 1991-09-12
Abstract: PURPOSE:To improve fatigue strength of a welding joint by positioning the center of a rotary cutter on the surface vertical to the plate surface containing a toe part of weld of a fillet welding joint and grinding the toe part of weld a little to the direction of the plate thickness. CONSTITUTION:When a fatigue load is loaded on the fillet joint by the arc welding, a fatigue crack is generated generally on the toe part of weld and cracks propagates in the plate thickness direction and is broken. This is caused mainly by stress concentration based on the shape of the toe part of weld. The toe part of weld is ground by a grinder and a rotary cutter to improve the fatigue strength of the welding joint and the radius of the toe part of weld is increased. In this case, the position P of the largest stress approaches a little to the welded metal side to a surface vertical to the plate surface containing the center of the radius of the toe of weld. When the welding joint is ground so that the strength of the material at the position where the maximum stress is generated is higher, the plastic deformation is hard to occur, the fatigue cracks are hard to occur and the fatigue strength of the welding joint, too, is improved remarkably.

Title: Video tape recorder
Inventor: SATO HIDEO
IPC: H04N5/91
Filed: 1989-10-05
Abstract: PURPOSE:To automatically adjust the level of a reproducing video signal by connecting the reproducing video signal to an AGC circuit at the time of reproducing, connecting an input video signal to the AGC circuit at the time of not reproducing and fixing the gain of an FM demodulation circuit. CONSTITUTION:At the time of reproducing, the reproducing video signal processed by a reproducing signal processing circuit 1 is inputted in the AGC circuit 11 through a switching means SW1 and its level is adjusted in the circuit 11. On the other hand, when not reproducing, the input video signal is inputted in the AGC circuit 11 through the switching means SW1 and transmitted to a recording signal processing circuit or an EE circuit after adjusting its level. Since the gain of the FM demodulation circuit 6 provided in the circuit 1 is fixed, the level of a demodulation signal which is FM demodulated is not adjusted in the circuit 6. Thus, the brightness of a reproduced video is appropriately adjusted and the adjustment of the level is automatized, thereby facilitating an operation.
