Title: Shuichi Numata and Leaky Cable Innovation.

Introduction

Shuichi Numata is an inventor associated with Proterial, Ltd. in Tokyo, Japan. His patent work includes a leaky cable design intended to reduce misalignment between the cable’s electromagnetic-wave leakage slots and its insulator.

Latest Patents

Numata is credited with 1 patent: “Leaky Cable and Method of Manufacturing Leaky Cable.” The invention describes a cable with a linear insulator and a metal layer formed around its outer surface. Slots through the metal layer allow electromagnetic waves to leak outward, while unevenness on the insulator’s surface helps keep the slots aligned.

The manufacturing method involves forming a cylindrical thermoplastic-resin insulator, roughening its outer surface, applying a metal layer, and creating slots through that layer. The design combines a method for controlled electromagnetic-wave leakage with a surface feature intended to inhibit slot misalignment.

Career Highlights

Numata’s listed patent reflects work on cable construction and manufacturing processes. The invention addresses both the cable’s functional structure and a production consideration: maintaining alignment between the leakage slots and the underlying insulator.

Collaborations

Numata’s listed coworker is Takahiro Sugiyama. The available information identifies both inventors in connection with the cable invention and lists Proterial, Ltd. as Numata’s company.

Conclusion

Shuichi Numata’s patent focuses on a leaky cable whose surface design helps preserve slot alignment while enabling electromagnetic waves to pass through its metal layer.
