Title: Innovations of Toshikazu Morioke
Introduction
Toshikazu Morioke is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of optical devices, holding a total of 8 patents. His work focuses on enhancing the performance and efficiency of vibration-wave motors, which are crucial in various optical applications.
Latest Patents
One of Morioke's latest patents is a drive apparatus, drive method, and optical device designed to minimize noise produced during phase-difference changes without compromising the responsiveness of a vibration-wave motor. This innovation involves a lens-side microcontroller unit (MCU) for a lens barrel that controls a drive apparatus. The drive apparatus applies a drive voltage to the vibration-wave motor by outputting an A-phase drive signal and a B-phase drive signal. The lens-side MCU incorporates a drive-voltage setting unit and a duty-cycle change unit to adjust the drive voltage. Additionally, it features a phase-difference change unit that alters the phase difference between the A-phase and B-phase drive signals. When operating the vibration-wave motor, the lens-side MCU adjusts the drive voltage to V, and during phase-difference changes, the drive voltage is modified to a value greater than zero and less than V.
