  • Patent number: 9297788
    Abstract: A determination assist system including a first image generating section for generating a first planar image based on data of a first test index; a second image generating section for generating a second planar image based on data of a second test index; a differentiation section which differentiates the first planar image and the second planar image to generate a first differential image and a second differential image, respectively; a binarization section which binarizes the first differential image to generate a first binary image including a first region which is not less than a first threshold and a second region which is less than the first threshold, and binarizes the second differential image to generate a second binary image including a third region which is not less than a second threshold and a fourth region which is less than the second threshold; and a determination image generating section.

  • Patent number: 8590766
    Abstract: This invention provides a method for inspecting a joined region and joining strength of a joined object formed by a spot friction stir joining process. In this method, an ultrasonic wave is introduced into the joined object from a backing face 25 opposed to a joining tool plunging face 24 and the ultrasonic wave reflected from the joined object 20 is taken in. In this case, the joining region 21 and the joining strength is estimated by observing a reflected wave of the ultrasonic wave in the vicinity of a position, along a reference direction Z, corresponding to an interface 27 of two joining members, without using the reflected wave of the ultrasonic wave reflected from the joining tool plunging face, thereby inspecting the joined object based on the estimation result.

  • Patent number: 5475613
    Abstract: A three dimensional object under test is measured to obtain shape data representing a shape of the three dimensional object. The object under test is measured using, for example, an ultrasonic probe LED to obtain defect test data. A processing mechanism forms a three-dimensional graphic image of a defect zone from the defect test data and a three-dimensional graphic image of the object under test from the shape data. A display mechanism is provided for displaying the three-dimensional graphic image of the defect zone superimposed over the three-dimensional graphic image of the object under test.

  • Patent number: 5433106
    Abstract: To improve the detection precision and detection efficiency and further to automatize the detection process, moisture in a honeycomb panel is detected as follows: the honeycomb panel is heated by a lamp; the surface temperature of the heated construction is measured by an infrared radiation thermometer; the measured temperature is displayed to roughly discriminate an abnormal portion (i.e., a portion containing moisture); the honeycomb panel is further heated continuously to detect temperature-change-rates at both abnormal and normal portions (i.e., a portion not containing moisture); and the two temperature-change-rates are compared with each other to discriminate a presence of moisture.
