20100119145 | METHOD OF MEASUREMENT OF NUMBER OF NONMETALLIC INCLUSIONS AND CASTING MOLD FOR OBTAINING CAST SAMPLE USED FOR SAME - A method of automatically counting a number of inclusions by eliminating the effects of shrinkage cavities in the conventional method and securing a high correlation with a value measured by a skilled worker and a casting mold for obtaining a cast sample used for the same are provided. A method of measurement of a number of nonmetallic inclusions comprising capturing an image of a rectangular fracture surface of a cast sample consisting of an aluminum alloy by a CCD camera or other image capturing means, processing the image captured by the image capturing means for color density, digitalizing the processed image by a predetermined threshold value, and counting the number of pixel clusters of a predetermined size or more, the method characterized by detecting the end edges of the short sides of the rectangular fracture surface before the capturing of its image and automatically setting measurement regions of an area of ¼ to ⅔ of the area of the fracture surface at the two ends of the fracture surface. A casting mold for obtaining a cast sample comprised of a top mold having a recess and a bottom mold having a sprue, having a substantially rectangular parallelepiped cavity extending in the melt flow direction in the state where the top mold and the bottom mold are assembled, and provided, at equal intervals at the bottom of the recess of the top mold with a handle, with inverted V-shaped projections extending in a direction vertical to the melt flow direction. | 05-13-2010 |

20090263005 | IMPURITY MEASURING METHOD AND DEVICE - An impurity measuring device includes a table (T) on which a sample (S) is to be placed with its fracture surface (h) facing up, an illuminating means (7) for irradiating the fracture surface (h) with light (L) from a plurality of directions, an image sensing means for sensing an image of the fracture surface (h) irradiated with the light (L), continuous tone color image processing means for processing the sensed image into a continuous tone color image, and a binarizing means for binarizing the continuous tone color image through comparison between the result of the continuous tone color image processing and a threshold value. As the fracture surface (h) is irradiated with the light (L) from the plurality of directions, the image obtained by sensing the image of the fracture surface (h) is free from shading or optical irregularities caused by minute irregularities on the fracture surface (h). Therefore, impurities in the sample (S) can be accurately detected from the fracture surface (h) by subjecting the image to the continuous tone color image processing and binarization. | 10-22-2009 |
