Title: Takashi Morii: Innovator in Ultrasonic Testing and Grinding Technologies

Introduction

Takashi Morii is a prominent inventor based in Chiba, Japan. He has made significant contributions to the field of ultrasonic testing and grinding technologies. With a total of 2 patents, his work focuses on improving the detectability of structural issues in materials.

Latest Patents

Morii's latest patents include a method and apparatus for ultrasonic testing of the surface of columnar structures. This innovative ultrasonic testing method utilizes surface waves to prevent false detection of primary cracks. It also aims to lower the level of structural noises from grain boundaries, thereby enhancing the detectability in ultrasonic testing of hot rolling rolls. The surface wave probe he developed is equipped with a piezoelectric element, a resin wedge, and a damping block. This probe is designed to produce a short pulse that is at most 2.5 times the wavelength of the surface wave. A coupling liquid medium is supplied to the probe based on the peripheral speed of the roll being tested. The height of the reflected waves measured allows for the determination of the grinding allowance of the roll, which can be adjusted accordingly.
