Latest Patents

One of Nagata's latest patents is a magnetostrictive torque detecting apparatus. This invention aims to achieve stable linear torque-output characteristics over a wide torque range. The apparatus features a shaft to be measured, an exciting coil for magnetically exciting the shaft, and a detecting coil for detecting magnetostrictive components generated in the shaft distorted by torque. The shaft is composed of a substrate shaft portion made of a high yield point material and a shape anisotropic layer portion made of a high magnetostrictive material, which is metallographically welded to the outer surface of the substrate shaft. The welded layer is designed with two symmetrical groups of concave/convex portions arranged at regular angular intervals on the outer circumferential surface, inclined with respect to the axial direction of the shaft.

Another notable patent is for a steel for plastics molds that is superior in weldability. This steel consists of specific percentages of carbon, manganese, chromium, molybdenum, vanadium, and sulfur, with the balance being substantially iron. The alloy composition is designed to meet particular criteria to enhance its performance in mold applications.
