摘要： A resist coating for etching use which enables high speed and high accuracy patterning is provided by applying, to a steel strip, a negative resist ink which solidifies upon exposure to light; drying the ink to form a resist coating; then irradiating the steel strip with light while moving a mask member in synchronization with a traveling speed of the steel strip, the mask member being configured to cover a surface of the resist coating to block light, to thereby solidify a portion of the resist coating not covered with the mask member to form a solidified portion; and removing an unsolidified portion other than the solidified portion with a developing solution. Subsequently, by dissolving and removing by etching a portion of the steel strip below the removed portion of the resist coating, a fine and uniform linear groove can be formed in a surface of the steel strip.

摘要： A material containing a soft magnetic substance is subjected to a plastic deformation such as a roll processing to obtain a rod-shaped body. Then, the rod-shaped body or a shaped body obtained by processing the rod-shaped body into a shape other than a flat plate shape is subjected to a heat treatment in the presence of a magnetic field. The rod-shaped body or the shaped body is made magnetic-anisotropic by the heat treatment thereby to obtain a magnetic-anisotropic plastically deformed body.

摘要： An improved magnetic core for an electrical transformer, and a method and apparatus for forming the core, are disclosed wherein the corners of core windows are configured to decrease the magnetic path length, thereby reducing the core losses and the amount of material necessary to construct the core. One exemplary embodiment includes a core window opening having an outer corner radii that are larger than the inner corner radii. Alternatively, the core window may have corners of a non-constant radii, with the outer corners having a more gradual or gentle curvature. These and other disclosed embodiments also enhance the ease of assembly of the transformer core and thus decrease or eliminate damage to the magnetic material during assembly.
