Title: Daisuke Kimura: Innovator in Electromechanical Actuators and Piezoelectric Printing Technology

Introduction

Daisuke Kimura is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of printing technology, particularly through his innovative designs of electromechanical actuators and piezoelectric printing heads. With a total of 4 patents to his name, Kimura's work has had a substantial impact on the efficiency and effectiveness of printing mechanisms.

Latest Patents

One of Kimura's latest patents is an electromechanical actuator used in wire-dot printing heads. This actuator features a stack composed of electromechanical elements, with an inactive element that divides the stack into two sections. In a wire-dot printing head utilizing this actuator, the stack sections are energized successively to enhance the forward stroke of a printing wire, enabling high-speed printing. Additionally, the actuator includes a spring that regulates and brakes the rearward stroke of the printing wire, preventing it from moving back beyond its initial position. Another aspect of this invention incorporates a stopper to forcibly halt the wire at the initial position during its rearward stroke. Furthermore, the actuator's stack is supported by a block through a leaf spring, which helps to prevent the generation of large stress within the stack.

Another notable invention by Kimura is a piezoelectric printing head. This head consists of an annular base frame and multiple piezoelectric actuator assemblies mounted on it. Each actuator assembly includes a piezoelectric element, which is secured to the base frame at one end, while the other end remains free. The assembly also features an armature with a base end and a tip end, to which a printing wire is rigidly connected, along with a magnifying mechanism. When the piezoelectric element is energized, its displacement is magnified and transmitted to the printing wire. A vibration damping buffer member is placed between the base frame and the base end of the armature to enhance performance.
