Title: Makoto Shirai: Innovator in Ultrasonic Testing Technology

Introduction

Makoto Shirai is a distinguished inventor based in Ibaraki, Japan. He has made significant contributions to the field of ultrasonic testing, particularly in the development of methods and instruments that enhance the precision of defect detection in materials.

Latest Patents

Shirai holds a patent for an "Ultrasonic test method and ultrasonic test instrument used for the method." This innovative method allows for the detection of defective portions in a noncontact manner. The ultrasonic wave is transmitted from a transmitter positioned on one side of the object under test, while the reflected wave is received by a receiver on the same side. The design ensures that the air propagation time between the transmitter and receiver is longer than the propagation time of the reflected wave, effectively blocking the ultrasonic wave's propagation through the solid body. This invention is particularly suitable for testing laminated materials, such as CFRP and insulation, without direct contact.
