  • Publication number: 20150053012
    Abstract: An ultrasonic testing sensor and an ultrasonic testing method are provided which achieve a high sensitivity of three-dimensional ultrasonic testing and a high S/N ratio, do not require development of a sensor for each inspection object, and reduce the cost of developing a sensor. The ultrasonic testing method is performed with the use of the ultrasonic testing sensor while a total length d, extending in a direction parallel to an ultrasonic scanning direction, of ultrasonic elements to be simultaneously excited with a single exciter is controlled to be in a range ensuring that 2d·sin ?=n·?, where ? is a wavelength of an ultrasonic wave, n is an integer of 1 or 2, and ? is an angle at which the ultrasonic wave is incident.

  • Patent number: 8225672
    Abstract: The present invention is intended to provide a method for assessing remaining lifespan of a bolt with higher precision than conventional methods, which can be applied to a bolt comprising a high alloy with fewer tissue changes caused by creep damage. The present invention provides a method for assessing the remaining lifespan of a bolt used at high temperatures, including: carrying out a creep test for a bolt material that constitutes a bolt to be assessed and determining a life-time and a life-elongation rate; determining a time-temperature parameter based on the life-time and the creep test temperature; creating a lifespan-assessment diagram by plotting the time-temperature parameter with respect to the life-elongation rate; measuring a elongation rate between before and after the use of the bolt to be assessed; and assessing the remaining lifespan of the bolt with the use of the elongation rate between before and after the use of the bolt to be assessed and the lifespan-assessment diagram.
