Title: Gijun Idei: Innovator in Non-Destructive Testing Technologies

Introduction

Gijun Idei, an accomplished inventor residing in Yokohama, Japan, has made significant contributions to the field of non-destructive testing. With a total of four patents to his name, Idei's work primarily focuses on innovative methods and devices for inspecting materials without compromising their integrity.

Latest Patents

Among his most notable inventions are two recent patents that enhance non-destructive inspection techniques. The first patent describes a **Calibration Device for Non-Destructive Inspection/Measurement System and Non-Destructive Inspection/Measurement Method**. This device includes an excitation coil, a detection coil, and a computer that applies sinusoidal signals to a pipe body. The innovative feature of this device is its ability to calibrate detection results by using variables in simultaneous equations derived from the amplitudes and phase differences of the output voltage at multiple calibration points.

The second patent outlines a **Nondestructive Inspection Device Using Alternating Magnetic Field and Nondestructive Inspection Method**. This invention addresses limitations in conventional non-destructive inspection devices that only assess the surface layer of objects due to the skin effect. Idei's device eliminates the surface effect by incorporating an external signal to cancel out the surface detection output. Consequently, this allows for effective flaw detection and thickness inspection of the interior of thick-structured test objects.
