Latest Patents
Ohtsuka holds a patent for a "Head for wire dot printer." This invention features a wire dot printer head that includes a leaf spring welded to an armature, which is biased by a permanent magnet. The design incorporates a magnetic coil that erases the magnetic field of the permanent magnet, allowing the leaf spring to be released and drive a print wire. The leaf spring is composed of an alloy that consists essentially of 13-14 wt % Cr, 0.37-0.43 wt % C, 0.25-0.5 wt % Si, 0.3-0.5 wt % Mn, 1.15-1.35 wt % Mo, and the balance Fe. This specific alloy enhances the width of the weld metal of the leaf spring and deepens the weld penetration, thereby minimizing the generation of micro-cracking.
