Title: Masashi Tomita: Innovator in Ink Jet Technology
Introduction
Masashi Tomita is a prominent inventor based in Kumamoto, Japan. He has made significant contributions to the field of ink jet technology, holding 2 patents that showcase his innovative approach to printing solutions.
Latest Patents
Tomita's latest patents focus on advanced ink jet recording apparatuses. The first patent describes an ink jet recording apparatus that includes a head body with a nozzle and a pressure chamber. It features an actuator with a piezoelectric element and an electrode for applying voltage. The driving circuit supplies a driving signal that includes a pulse signal applied with an interval shorter than a predetermined pulse interval, which is equal to a Helmholtz period of the head. Additionally, a longer interval pulse signal is also applied within the same printing cycle.
The second patent also pertains to an ink jet recording apparatus, which similarly includes a head body, actuator, and driving circuit. This design ensures that the driving circuit always supplies an auxiliary pulse signal in every printing cycle. When ink is to be discharged, the driving circuit provides an ink discharge pulse signal after the auxiliary pulse signal, allowing the ink meniscus vibration in the nozzle to resonate with that caused by the auxiliary pulse signal.
