Title: The Innovative Contributions of Yoshiyuki Iwami
Introduction
Yoshiyuki Iwami, an accomplished inventor based in Obihiro, Japan, has made notable contributions in the field of electrical engineering. With a focus on contact apparatus design and safety relay technology, Iwami holds two patents that embody his innovative spirit and technical expertise.
Latest Patents
Iwami's recent patents include a contactor and a safety electromagnetic relay. The contactor features a unique design where a permanent magnet is strategically placed near the fixed and movable contact points. This arrangement allows the arc generated during operation to be directed laterally by the magnetic force, effectively elongating the arc and improving performance. Additionally, an arc-extinguishing member surrounds the contact points, generating gas to extinguish the arc efficiently.
His second patent, the safety electromagnetic relay, introduces a dual contact set system designed to ensure safety in electrical load interruption. Each of the two pairs of contact sets comprises load-driving and control contact sets. The innovative aspect of this relay lies in its ability to maintain functionality even if one set becomes welded in a closed position, thereby enabling the other set to open. This design not only enhances safety but also provides a status signal for the relay's operational health.
