Abstract

432,152. Magnets. MITSUBISHI DENKI KABUSHIKI KAISHA, 4, Nichome Marunouchi, Kojimachi-ku, KATO, Y., 1220, Togoshi-machi, Ebara-ku, and TAKEI, T., 83, Jiyugaoka Meguroku, all in Tokio. Aug. 14, 1934, No. 23428. [Class 35] In a magnet consisting of a magnetized mass of particles of oxide of iron and other metals, disintegration is prevented by an exterior protective covering or by a reinforcement embedded in the material or by both of these strengthening means in conjunction. The material may be oxides of iron and nickel or cobalt and has an external cover of gauze, sheet metal, enamel or lacquer, or alternatively, or in addition, it has reinforcing bars 5 embedded in the magnetic material 1. The bars may be of nickel, porcelain or earthenware.
