Latest Patents
One of Kiji's latest patents is for a liquid ejection head. This invention includes a nozzle plate, pressure chambers, actuators, and a drive circuit. The nozzle plate features nozzles for ejecting liquid, while the pressure chamber communicates with these nozzles. The actuator adjusts the volume of the pressure chamber based on a drive signal generated by the drive circuit. This drive signal includes an ejection waveform designed to cancel vibrations at specific acoustic resonance frequencies.
Another notable patent is for an inkjet head and inkjet recording apparatus. This invention consists of a pressure chamber, an actuator, and an application unit. The pressure chamber holds liquid, and the actuator modifies the chamber's volume in response to a drive signal. The application unit sends this signal to the actuator, which includes both discharge and vibration pulses. The timing and characteristics of these pulses are carefully designed to optimize liquid discharge from the nozzle.
Career Highlights
Throughout his career, Yasuhito Kiji has worked with notable companies such as Toshiba Tec and Riso Technologies Corporation.
