摘要： A water intake portion of a hydraulic machine consists of a casing and a speed ring positioned between the casing and guide vanes for guiding water from the casing to the guide vanes. The speed ring consists of a pair of upper and lower flat members of a ring form, a plurality of stay vanes positioned between the aforesaid pair of members for interconnecting same rigidly, and a reinforcing member of a cylindrical form, which is welded to the top surface of the upper flat member between the inner and outer circumferential edges of the upper flat member. Edges defining therebetween an opening of this casing are welded to the top surface of the upper flat member of a ring form, of the speed ring in the position between the aforesaid reinforcing member and the outer circumferential edge of the upper flat member, as well as to the undersurface of the lower flat member of a ring form, respectively. In this respect, the welding of the reinforcing member of a cylindrical form to the top surface of the upper flat member of a ring form is followed by the welding of the edges of the opening of the casing to the upper and lower flat members of a ring form.

摘要： The susceptibility of austenitic stainless steel is tested by inputting a highly magnified image of the polished and etched steel surface through a microscope, a CCD camera and an input device into an image processor. The image processor is set up to identify grain boundary locations in the image, take width measurements across the grain boundaries, based on luminance distribution, and calculate average and maximum values for the measured widths. These calculated measured values are compared with experimentally-determined reference values -1 to 1.5 .mu.m for mean width and 2 to 3 .mu.m for maximum width - and a susceptibility status determined accordingly. The status can then be output using a display e.g. screen or printer.
