Latest Patents

Takahito's latest patents include an ultrasonic flaw detection device, an ultrasonic flaw detection method, and an ultrasonic flaw detection program. The ultrasonic flaw detection device utilizes a phased-array ultrasonic-flaw-detection probe. This probe is strategically placed so that its center of curvature aligns with a reference center of curvature of the subject being examined. The probe is then translated along a designated scan direction, emitting an ultrasonic beam that converges at the center of curvature of the subject's cross-section. The reflected beam is analyzed to estimate the length of any flaws present in the circumferential direction of the subject. Furthermore, the estimated length is adjusted using a correction coefficient that accounts for the distance between the reference and scan positions in the thickness direction of the subject.

Another notable patent is the ultrasonic testing device and method, which is designed for flaw detection on a stringer with a substantially rectangular inner circumferential surface. This device features a shoe that contacts the corner of the stringer's inner surface, along with an ultrasonic array fixed to the shoe. This configuration creates a medium space for propagating ultrasonic waves
