  • Patent number: 8774454
    Abstract: A flaw detection image analyzer (10) takes in an inspection procedure command stored in a flaw detection condition database (40), takes in a flaw detection image signal corresponding to a flaw detection image indicated by the taken inspection procedure command from a database (50) for flaw detection image signal, and displays the flaw detection image based on the flaw detection image signal on a display (30), with a display range and a contrast indicated by the inspection procedure command in an arrangement pattern of image indicated by the inspection procedure command. Consequently, optimum images can be displayed sequentially with optimum arrangement pattern, optimum display range and contrast according to a flaw to be inspected when a flaw is detected by observing an ultrasonic flaw detection image.

  • Publication number: 20120037121
    Abstract: An engine includes a head cover covering an upper part of a cylinder head to accommodate a valve gear mechanism and an injector. The head cover is separatable into a lower cover body and an upper cover body detachable from and attachable to the lower cover body. The lower cover body includes a fuel pipe and a relay connector. Through the fuel pipe, fuel is supplied to the injector. The fuel pipe penetrates through the lower cover body. The relay connector is configured to relay power supply from outside the head cover. The relay connector is attached to the lower cover body. One end side of an injector harness disposed in the head cover is coupled to a terminal portion of the injector. Another end side of the injector harness is coupled to the relay connector.

  • Patent number: 7239736
    Abstract: When a three-dimensional structure is formed by welding a plurality of members, accurate welding can be performed matching the three-dimensional shape. The teaching data consisting of the three-dimensional position at each of the welding points determined on each of the welding lines at a predetermined spacing on the basis of the design data of the three-dimensional structure is stored in a memory 18. A laser slit light sensor (a laser slit light emitting section 12 and a CD camera 13) is controlled by a total controller 17 via a camera controller 14 to photograph the welding point in order to obtain the image data of the welding point. An image processing apparatus 16 processes the image data to determine the amount of deviation from the design data of welding points.

  • Patent number: 6919956
    Abstract: A method and apparatus automatically repairs cracks produced in a member to be repaired. A wide field image is obtained by photographing the whole surface of a blade 31 or the like in a wide field view by a remote camera 11 and the position of cracks on the surface of the blade is obtained as a rough position information of the cracks by processing the image of wide field view. Then the cracks are photographed in a narrow field view at the predetermined spacing along the cracks based on the rough position information by a light section method. The narrow field images are processed to obtain the position, width, and depth of the crack at each predetermined spacing, which compose crack data at the series of points, and the cracks are repaired based on the crack data at the series of points.
