Title: Hiromu Narumiya: Innovator in Liquid Ejector Technology
Introduction
Hiromu Narumiya is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of liquid ejector technology, holding a total of 3 patents. His innovative work focuses on enhancing the efficiency and precision of ink ejection processes.
Latest Patents
One of Narumiya's latest patents is a liquid ejector that utilizes a high-order ultrasonic wave to eject ink. This invention allows for the control of droplet diameter without modifications to the nozzle plate. By applying radiation pressure intermittently to an opening, a high-order standing wave is generated at the liquid surface, enabling multiple droplets to be emitted simultaneously. The droplets produced are smaller than the opening diameter and are ejected vertically upward. The droplet size can be adjusted by altering the order of the high-order standing wave.
Another notable patent is an acoustic liquid ejector and printer apparatus that incorporates this ejector. This device increases the density of acoustic energy to enhance droplet ejection efficiency. Acoustic waves are introduced from a piezoelectric transducer into a liquid ink reservoir, reflecting off a parabolic wall. The ejection opening, located near the focal point of the parabola, allows for focused acoustic waves, which increases the energy density at the ejection point, resulting in efficient ink droplet ejection.
