Introduction

Toshiharu Tsubata is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of ultrasonic technology, holding a total of 3 patents. His work has been influential in advancing the capabilities of ultrasonic motors and transducers.

Latest Patents

One of Tsubata's latest patents is an ultrasonic motor that includes a vibrator, a mobile unit, a holding mechanism, and a pressing mechanism. The vibrator generates elliptical vibration by degenerating different vibration modes and having a phase difference between these modes. The mobile unit is designed to move relative to the vibrator, while the holding mechanism secures the vibrator in a direction that is substantially parallel to the mobile unit's movement. The pressing mechanism ensures that the vibrator is pressed against the mobile unit. Additionally, the holding mechanism features an adjustment unit that aligns the resonant frequencies of the different vibration modes to match each other when the motor is in operation.

Another significant patent involves an ultrasonic piezoelectric transducer and an ultrasonic actuator that perform enhanced elliptical vibration. This invention comprises a first laminated piezoelectric element with a fixed end, a resonator mounted at the opposite end, and a second laminated piezoelectric element that is fixedly mounted to the resonator. This structure allows for enhanced elliptical vibration with a large, controllable amplitude.
