Title: Akimitsu Tanabe: Inventor in Leak-Testing Technology.

Introduction

Akimitsu Tanabe is an inventor based in Tokyo, Japan, whose work focuses on methods and devices for detecting leaks. His patent portfolio includes 2 patents. Tanabe is associated with Fukuda Co., Ltd.

Latest Patents

Tanabe’s listed patents address leak-testing methods and the design of test conditions. One invention describes a method and device for designing leak-test conditions, along with a leak-testing method and device. It uses the test piece’s internal volume and the remaining volume of its capsule to establish test parameters. The method also converts differential-pressure and helium-leak measurements into equivalent standard leak-rate values for comparison and display.

Another invention presents a method for identifying fine leaks while accounting for tracer gas released by non-defective workpieces. It compares tracer-gas measurements from a test workpiece with measurements from a non-defective workpiece of the same specifications. The process includes exposing the workpiece to pressurized tracer gas, placing it in a sealed container, evacuating the container, and measuring the tracer gas.

Career Highlights

Tanabe’s listed inventions apply measurement and comparison techniques to improve leak testing. They address both the design of test conditions and the challenge of distinguishing fine leakage from background tracer-gas release.

Collaborations

Tanabe’s listed coworkers include Takaaki Watanabe and Mao Hirata. His work is associated with Fukuda Co., Ltd.

Conclusion

Akimitsu Tanabe’s patent work centers on practical leak-testing methods that support test-condition design and more reliable detection of fine leaks.
