Title: Kazuo Nakata and Patent Innovation at Kobe Steel

Introduction

Kazuo Nakata is an inventor associated with Fujisawa, Japan, and Kobe Steel, Ltd. His patent work includes a method for automatically measuring the eccentricity of a core wire within a coated electrode without damaging it.

Latest Patents

The available information identifies one patent for Nakata: “Method for Automatic, Non-Destructive Measurement of Eccentricity.” The method uses at least two optical sensor sets, each comprising a light source and a line sensor. One sensor measures the diameter of the coated portion of the core wire, while another measures an uncoated portion. Comparing the positions and diameters of these portions makes it possible to determine the wire’s eccentricity. With three sensors, the method can also assess the position and thickness of an exposed wire portion to identify eccentricity caused by a misaligned or bent rod. Nakata’s listed patent count is 1 patent.

Career Highlights

Nakata’s documented patent contribution focuses on optical measurement and quality assessment for coated electrodes. The approach is designed to automate inspection while preserving the component being measured.

Collaborations

Nakata’s listed coworkers include Katsuhiko Nomura and Akihiko Iochi. His company affiliation is Kobe Steel, Ltd.

Conclusion

Kazuo Nakata’s patent describes a nondestructive optical technique for measuring core-wire eccentricity, reflecting a practical application of automation and precision inspection in electrode manufacturing.
