Title: Innovations by Hirokazu Yokota
Introduction
Hirokazu Yokota is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of optical technology, holding a total of four patents. His work primarily focuses on developing advanced optical-fiber scanning and illumination apparatuses.
Latest Patents
Yokota's latest patents include an optical-fiber scanner, an illumination apparatus, and an observation apparatus. The optical-fiber scanner features an optical fiber, a body fitted on the basal-end side of the optical fiber, and piezoelectric elements that cause the optical fiber to vibrate. The design includes a securing portion that positions the body farther away from the piezoelectric elements. The body is made of an elastic material and has a through-hole for the optical fiber. Additionally, the distal-end portion supports the optical fiber in a fitted state and has a rotator shape that gradually decreases in cross-sectional area toward the distal end.
The scanner unit consists of a tubular elastic part with marks outside a prescribed bonding region and a piezoelectric element bonded to this region. The piezoelectric element includes a piezoelectric body with two opposing electrode faces, each marked differently. The design ensures that the marks align when the piezoelectric body is bonded, allowing for effective contact with the outer surface.
