Title: The Innovative Contributions of Takeshi Nagai

Introduction

Takeshi Nagai is a prominent inventor based in Nara, Japan. He has made significant contributions to the field of piezoelectric technology, holding a total of 18 patents. His work focuses on enhancing the functionality and efficiency of piezoelectric devices, which are crucial in various applications.

Latest Patents

Among his latest patents are the coaxial flexible piezoelectric cable polarizer, polarizing method, defect detector, and defect detecting method. This invention provides a defect inspecting apparatus that specifies the position of a defect before polarization when it is included in a coaxial flexible piezoelectric member. The invention addresses the challenge of moving a piezoelectric tube during polarization, which typically requires a large force due to friction between the coaxial flexible piezoelectric member and a block-like conductor. Nagai's polarizing apparatus and method allow for the movement of the piezoelectric tube with a smaller force, enhancing operational efficiency.

Additionally, his defect detecting apparatus applies a direct current to the coaxial flexible piezoelectric member while moving a piezoelectric tube arranged at a hole of inspecting electrode means. This setup enables the marking of defect portions, allowing for precise identification and subsequent action. The design includes a conductive block with a divided path portion for the piezoelectric tube, which reduces friction and facilitates easier movement.

Another notable invention is the pressure-sensitive sensor, object detecting device, and opening-closing device. This device prevents the seizure of an object between an opening and an opening-closing unit. It incorporates a pressure-sensitive sensor that generates an output signal based on deformation, ensuring safety and efficiency in operation.
