Title: Shigeru Inaba and His Hinge-Type Relay Patents.

Introduction

Shigeru Inaba is an inventor associated with Zama, Japan, and Niles Parts Company, Ltd. His recorded work includes 2 patents, both concerning hinge-type relays and the operation of their electrical contacts.

Latest Patents

Inaba’s patents describe relay designs that improve contact reliability through a wiping action. In one design, a rocking cardinal piece on the armature rests on a fulcrum attached to the yoke. As the electromagnet moves the armature, the movable and fixed contacts meet or separate while wiping against each other. This action helps remove oxides, dust, and other contaminants that could interfere with electrical contact.

The other design uses a non-magnetic supporting piece, bent downward at one side of the armature, and a fulcrum that allows it to rock. The arrangement enables the contacts to wipe as they open and close, while also allowing the electromagnet’s magnetic flux to act effectively on the armature.

Career Highlights

Inaba’s documented patent work focuses on hinge-type relay mechanisms. The designs address both contact cleanliness and effective electromagnetic operation, supporting dependable switching performance.

Collaborations

Inaba’s listed coworkers include Sadao Nakano and Kazuji Katsutani. His work is associated with Niles Parts Company, Ltd.

Conclusion

Shigeru Inaba’s two recorded patents demonstrate a focused contribution to relay engineering, using rocking supports and contact-wiping motion to promote reliable electrical connections.
