Latest Patents

Nobuaki Yakoh holds a patent for a method of detecting flaws in thick wall steel pipes using ultrasonic technology. This method involves the use of a shear wave mode to detect internal surface flaws in the pipes. The transmitting probe is positioned at a slant relative to both the longitudinal and transverse directions of the pipe. This configuration allows the shear wave to be incident on the pipe at a refraction angle of 35 to 70 degrees. Consequently, the ultrasonic beam effectively impinges on surface flaws at the same angle, ensuring accurate detection.
