Title: Toshitaka Hirata: Innovator in Ink Jet Technology
Introduction
Toshitaka Hirata is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of ink jet technology, holding a total of 6 patents. His innovative approaches have advanced the efficiency and functionality of ink jet printing systems.
Latest Patents
Hirata's latest patents include a method of driving an ink jet printing head. This method involves applying a voltage falling edge of a first pulse signal to cause a piezoelectric element to contract, thereby increasing the capacity of a liquid passage to supply ink. Following this, a voltage rising edge of the first pulse signal is applied to expand the piezoelectric element, decreasing the capacity of the liquid passage to discharge an ink droplet through a discharge port. Additionally, a second pulse signal is applied after a predetermined delay to further enhance the ink droplet discharge process. Another notable patent is for an ink jet head that utilizes a grooved piezoelectric element. This design includes multiple grooves, diaphragms, and actuators, ensuring that the flexure force of each actuator effectively jets ink through the nozzle without interference from the stuffing material.
