Title: Keijiro Yamaguchi and Plywood Defect Inspection

Introduction

Keijiro Yamaguchi is an inventor associated with Meinan Machinery Works, Inc., in Aichi, Japan. His patent work addresses the accurate detection of defects in plywood during conveyor-based inspection.

Latest Patents

The provided information lists one patent for Yamaguchi: “Defect Inspection System and Defect Inspection Method.” The invention captures images of the plywood’s face and back surfaces as it moves along belt conveyors, generating depth information. Separate shape-measurement units measure the plywood away from the imaging gap, where conveyor vibrations could affect measurements. The system uses this shape information to correct the depth information before detecting defects. This approach is designed to identify warpage and bending accurately without flattening or otherwise distorting the plywood through correction.

Career Highlights

Yamaguchi’s listed patent reflects work on industrial inspection technology that combines imaging, shape measurement, and data correction. The supplied information identifies him as an inventor on one patent and associates him with Meinan Machinery Works, Inc.

Collaborations

Masamichi Iwamoto and Takehiko Tokuyama are listed as Yamaguchi’s coworkers. The provided information does not specify their roles in the patent or the extent of their collaboration.

Conclusion

Keijiro Yamaguchi’s listed invention focuses on improving plywood defect detection by correcting imaging data with shape measurements taken away from conveyor vibrations.
