摘要： To precisely measure bead cutting shapes of electric resistance welded pipes without being affected by difference in luminance level between cut and uncut portions in optical cutting images, an image is obtained by overlaying an optical cutting image with the optical cutting image subjected to thinning processing. A profile of the welded pipe is approximated with a quadratic function and a region containing the bead apex coordinates is identified as the bead. Shape data of the pipe surface at the portion corresponding to the bead portion is obtained from the preset left and right boundaries of the bead portion and the apex position of the separately-calculated bead portion, and bead width, height, slope angle, and unevenness at the left and right boundaries between the bead portion and base pipe portion, are each calculated, based on the left and right bead shape approximation functions and base pipe shape approximation function.

摘要： The present invention relates to a method for detecting chattering of a cold rolling mill rapidly and accurately, which occurs during cold rolling of a steel strips. The occurrence of the chattering is detected by a plurality of acoustic parameters derived from a sound measured in the vicinity of the cold rolling mill during the rolling. The acoustic parameters are the frequency range characteristic of the occurrence of the chattering, the acoustic intensities in the frequency bands which are n-th harmonics, the peak frequency of the acoustic frequency component distribution, the resonance factor, the peak intensity, and the like. A plurality of parameters may be provided by measuring and calculating the same parameter with different timing.

摘要： A work roll has a regularly and geometrically patterned uneven dulled section on the roll surface. Eavh uneven dulled section is composed of a crest and concavity and is of crater-like configuration. In order to obtain good performance in temper rolling, the crest is in a form of an annular ring extending around the edge of the concavity. According to the invention, pattern of arrangement of the uneven dulled sections is determined in relation to the diameter of the ring-shaped crests of the uneven dulled section so as to obtain optimum performance in producing good quality, exhibiting substantially high image clarify as coated by paint, enamel or so forth.

摘要： In one aspect of the invention, the sample surface is wetted with an aqueous solution of a fluorescent dye followed by rinses with water to remove an excessive amount of the dye so that the background fluorescence emission can be minimized to increase the efficiency of fingerprint detection. In another aspect, the fluorescent dye or a reagent to produce fluorescent substance is deposited on the sample surface by attaching a gelatin film impregnated with a solution thereof followed by peeling. In a further different aspect, a powdery fluorescent dye is deposited on to the sample surface followed by spraying of water after removing an excessive amount of the powdery dye so that the background fluorescence can be minimized. The invention also provides an apparatus for the fingerprint detection by the laser beam excitation of fluorescence, which is compact and portable as being composed of an ingenious combination of several units into an integral system.
