Introduction

Akiteru Takatsuka is a prominent inventor based in Otsu, Japan. He has made significant contributions to the field of ultrasonic technology, holding a total of 5 patents. His work focuses on enhancing the performance and efficiency of ultrasonic devices.

Latest Patents

One of his latest patents is an "Ultrasonic transmitting/receiving device and method for fabricating the same." This invention effectively suppresses ringing during the emission of ultrasonic waves, improving time resolution when measuring sonic velocity. The device includes a pair of ultrasonic transducers, each featuring a piezoelectric vibrator with a first and second electrode separated by a piezoelectric body. A backing, composed of the same material as the piezoelectric body, is in contact with the first electrode. The transducers are arranged to face each other, forming a substantially rectangular U-shape when viewed from the side.

Another notable patent is the "Method for selecting piezoelectric transformer characteristic." This method involves connecting a primary-side driving section of a piezoelectric transformer to a high-frequency generator while leaving the secondary-side generating section open. The high-frequency generator sequentially generates and sweeps a high-frequency signal over a predetermined frequency range. By measuring the resonant frequency of the input-impedance-versus-frequency characteristic of the transformer, the characteristic can be selected based on the measured resonant frequency.
