Title: **Toru Shimizu: A Pioneer in Shielded Communication Cables**

Introduction

Toru Shimizu, an innovative inventor based in Mie, Japan, has made significant contributions to the field of communication technology. With a total of 12 patents to his name, Shimizu has demonstrated expertise in developing advanced cable technologies that enhance signal quality and minimize interference, proving crucial for modern communication systems.

Latest Patents

Among his most recent innovations is a shielded communication cable designed to address noise interference issues. This cable consists of a pair of insulated wires twisted together, each containing a conductor covered by insulation with a relative dielectric constant of 2.5 or lower. A braided shield encases the twisted wires, while a film-shaped shield, containing a metal film, further enhances signal integrity. The jacket surrounding these elements has an inner diameter of 3.5 mm or smaller, and the cable maintains a characteristic impedance within the range of 100±5Ω.

Additionally, Shimizu has developed another type of shielded communication cable that features a parallel electric cable with insulated wires arranged parallel to one another, rather than twisted. This design improves noise shieldability and reduces signal propagation time differences. The effectiveness of these inventions aligns with the continuous demand for high-quality communication solutions in today’s technologies.
