Latest Patents

One of her latest patents is for a ferroelectric element and the process for producing the same. This ferroelectric element comprises a ferroelectric material containing at least two metals. The production process includes a sol-gel method in the presence of a thickener and/or an association preventive from aqueous solutions of respective salts of the metals. This innovation allows for easy handling of starting compounds, good storage stability of the starting compound solution, and low production costs. The ferroelectric element can be formed as a thin layer, resulting in fine and dense surface particles, which contribute to excellent surface smoothness and piezoelectric properties. This makes it particularly advantageous for use as a piezoelectric element in piezoelectric ink jet heads.

Another notable patent involves a similar ferroelectric element, which is produced through a process that includes providing alkoxides of the respective metals as starting compounds. The process also involves hydrolyzing the metal alkoxides in the presence of a catalytic amount of a protonic acid to increase the molecular weight. A film-forming polymer material is then added to the sol-like solution to prepare a ferroelectric precursor solution. This method allows for the formation of a thick film without creating any cracks, making it suitable for use in piezoelectric ink jet heads.
