    摘要： A method for making a folded fin for a heat sink comprises the steps of: preparing a metal plate; clamping the metal plate with three forming jigs in an initial position, the lower jig portion of the second forming jig having a tapered end; actuating the second forming jig to upwardly move toward the first forming jig at a specified angle and the third forming jig to horizontally move toward the first forming jig to a second position where a portion of the metal plate between the forming jigs has been bent into a pair of symmetrically inclined sections; and actuating the lower jig portion of the second forming jig to downwardly move away from the metal plate at a specified angle, and the third forming jig and the upper jig portion of the second forming jig to continue moving toward the first forming jig to a final position where the pair of symmetrically inclined sections of the metal plate has been bent double thereby forming a folded fin. A machine is disclosed to make the folded fin by the method disclosed above.

    摘要： The image-based container defects detector consists of a plurality of camera units, a sensor unit, a frame grabber, and an image recognizer unit. The sensor unit serves to detect the vehicles entering the inspection station, and transmit a signal to the frame grabber for capturing the vehicle image by triggering the CCD camera thereby obtaining the information about the container's defect position and size. By dexterously utilizing image processing technique, the HIS (hue, saturation and intensity) color is employed to distinguish a normal area from a defected area in the container. Then quad-tree and merge is used to segregate image roughly. As for the non-defected area becoming obscured due to noise is removed using a filter. Finally the defected area is displayed on the screen. The present invention is well-suited for after detection as well as for on-line immediate detection for defect containers.
