Latest Patents

Senno's latest patents include innovations in amorphous materials with improved properties. These materials incorporate at least one iron-transition metal, such as Fe, Co, or Ni, along with at least one metalloid like B, C, Si, or P. His research demonstrates that by substituting 0.5 to 10 atomic % of these iron-transition metals with Mn, excellent magnetic characteristics can be achieved. Furthermore, when these amorphous materials are partially substituted with Mn and include elements from Groups IIIa, IVa, Va, and VIa of the periodic table, the crystallization temperature is significantly increased.

Another notable patent involves a magnetic head design. This design features a core that consists of a front core and a back core. The front core is equipped with a wear-resistant non-magnetic base and a soft magnetic thin film. This thin film is divided into halves by a magnetic gap. The back core is constructed from a U-shaped block of soft magnetic material, with a wear-resistant non-magnetic member connecting the legs of the block. The innovative design allows for a closed magnetic path across the magnetic gap, enhancing the efficiency of the magnetic head.
