Patents by Inventor Tomoaki Mochiduki

Tomoaki Mochiduki has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Preferentially-oriented oxide ceramics, piezoelectric element, liquid discharge head, ultrasonic motor, and dust removing device
    Patent number: 8698380
    Abstract: Provided is a manufacturing method for preferentially-oriented oxide ceramics having a high degree of crystal orientation. The manufacturing method includes: obtaining slurry containing an oxide crystal B having magnetic anisotropy; applying a magnetic field to the oxide crystal B, and obtaining a compact of the oxide crystal B; and subjecting the compact to oxidation treatment to obtain preferentially-oriented oxide ceramics including a compact of an oxide crystal C having a crystal system that is different from a crystal system of one of a part and a whole of the oxide crystal B. By (1) reacting raw materials, (2) reducing the oxide crystal A, or (3) keeping the oxide crystal A at high temperature and quenching the oxide crystal A, the oxide crystal B is obtained to be used in the slurry.
