Title: The Innovations of Takashi Kasashima
Introduction
Takashi Kasashima is a prominent inventor based in Ichinomiya, Japan. He has made significant contributions to the field of piezoelectric materials, holding a total of 7 patents. His work focuses on developing lead-free piezoelectric ceramic compositions that have a wide range of applications.
Latest Patents
Among his latest patents is a lead-free piezoelectric ceramic composition that includes an alkali niobate/tantalate perovskite oxide main phase with piezoelectric properties and a different metal oxide. The mole ratio (Na/K) between sodium (Na) and potassium (K) in the main phase is defined within the range of 0.40 < (Na/K) < 3.0. The main phase exhibits a crystal structure characterized by first spots corresponding to a primitive lattice period and second spots corresponding to a lattice period that is twice the primitive lattice period. These features are observable in an electron beam diffraction image entering from the <100> direction, with the main phase represented as a pseudo-cubic crystal system. Additionally, the area ratio of a crystal phase reflecting the second spots in the main phase is 33% or less, and the maximum grain size of crystals reflecting the second spots is 25 nm or less.
