Latest Patents

One of his latest patents is the "Ink Droplet Expelling Apparatus." This invention discloses a mechanism for expelling ink droplets in response to electric signals. It comprises a printing head with multiple ink chambers, electro-mechanical transducers, and a driving signal generating circuit. The transducers are activated by three distinct driving signals, which work together to expel ink droplets efficiently from the nozzle. The first signal imparts velocity to the ink, the second accelerates it for expulsion, and the third stabilizes pressure fluctuations while replenishing ink from the tank.

Another notable patent is the "Ink Jet Printing Apparatus." This apparatus features a nozzle head with orifices for ejecting ink particles and pressure chambers equipped with piezoelectric elements. These elements generate pressure waves in the ink, facilitating precise ejection through the orifices. The electrical signal applying device plays a crucial role by applying main and sub-electrical signal pulses to control the pressure waves effectively.
