Title: Seiichi Saito and Soft Magnetic Alloy Powder Innovation.

Introduction

Seiichi Saito is an inventor associated with Ichihara, Japan, and Mitsubishi Steel Mfg. Co., Ltd. His recorded patent work concerns soft magnetic alloy powder designed to reduce energy loss in dust cores and support operation at higher frequencies and larger currents.

Latest Patents

Saito is associated with 1 patent: “Soft Magnetic Alloy Powder and Production Method Therefor.” The invention describes an Fe–Cr–Si-based soft magnetic alloy powder in which the chromium content gradually decreases from the particle surface to a specified depth. The powder contains 3 to 6.5 percent silicon by weight and may contain 1 to 5 percent chromium by weight, along with optional manganese, phosphorus, sulfur, or oxygen. The chromium oxide-to-metallic chromium ratio may also gradually decrease inward from the surface. These features are intended to reduce losses in dust cores and help them meet the demands of higher-frequency and higher-current applications.
