Title: Method for detecting boundary by color information
Inventor: NAKAGAWA WATARU
IPC: H04N7/18
Filed: 1989-03-16
Abstract: PURPOSE:To quickly and accurately detect a boundary by setting a threshold value for binarization so that the peak level of a Hough value can go to the maximum value or be set at a value in the neighborhood of the maximum value in a Hough transformation processing to find the boundary after the binarization. CONSTITUTION:An unworked land M and a worked land K are displayed on the left and right parts of a screen 35 in a color image pickup means 24, and image pickup is performed so that the boundary Ko can be set in a longitudinal direction, and the digital signals of three colors R, G, and B are read in an image memory 28. The binarization is executed by changing the threshold value of each color by an image processor 29, and the threshold value is set so as to set the peak value of the Hough value obtained in Hough transformation at the maximum value or in the neighborhood of the maximum value. After that, a binarization processing is performed with the threshold value by which the image information of the unworked land M and the worked land K read in at the image pickup means 24 are defined as advancing a travel working machine, then, the boundary Ko can be decided. In such a way, it is possible to shorten processing time until the boundary is detected.

Title: Method of removing edge of magnetic core
Inventor: IKEDA TANEJIROU
IPC: H01F41/02
Filed: 1982-04-19
Abstract: PURPOSE:To prevent the leakage caused by the breakage of the cover of a conductor by a method wherein laser beams are applied to the edge of a magnetic core and that near the through hole to remove the angular section. CONSTITUTION:A magnetic core is horizontally held and, by setting the diameter of a YAG laser beam at 0.2-0.8mm. in the form of a spot, processed along its edge. Power is minimized so that a crack is prevented from being generated in ferrite. At this time, the point corner thereof is rounded. Power is slightly raised comparing with the case of ferrite to process the glass allowed to flow into the hole. Thus the roundness can simply be added so as to prevent the cover 7 of a conductor 6 from breaking and to reduce the leakage failure of the winding.
