==LIQUID EJECTION APPARATUS AND DETERMINATION METHOD CAPABLE OF DETERMINING WHETHER OR NOT LIQUID FILLING OF PRESSURE CHAMBER HAS BEEN COMPLETED - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18455566 titled 'LIQUID EJECTION APPARATUS AND DETERMINATION METHOD CAPABLE OF DETERMINING WHETHER OR NOT LIQUID FILLING OF PRESSURE CHAMBER HAS BEEN COMPLETED

==Simplified Explanation==

The liquid ejection apparatus described in the patent application includes a nozzle, pressure chamber, piezoelectric element, output processing portion, and determination processing portion. The nozzle ejects liquid, while the pressure chamber holds the liquid and communicates with the nozzle. The piezoelectric element changes pressure in the chamber in response to a drive signal input. The output processing portion causes the piezoelectric element to output an electric signal corresponding to vibration in the chamber. The determination processing portion determines if the pressure chamber is filled with liquid based on the frequency of the electric signal.

* Nozzle ejects liquid
* Pressure chamber holds liquid and communicates with nozzle
* Piezoelectric element changes pressure in chamber in response to drive signal
* Output processing portion causes piezoelectric element to output electric signal corresponding to chamber vibration
* Determination processing portion determines if pressure chamber is filled with liquid based on frequency of electric signal

== Potential Applications ==
The technology can be applied in inkjet printers, 3D printers, and medical devices for precise liquid ejection.

== Problems Solved ==
This technology solves the problem of accurately determining the liquid-filled state of a pressure chamber in liquid ejection devices.

==Original Abstract Submitted==

A liquid ejection apparatus includes a nozzle, a pressure chamber, a piezoelectric element, an output processing portion, and a determination processing portion. The nozzle ejects a liquid. The pressure chamber communicates with the nozzle and contains the liquid. The piezoelectric element changes a pressure in the pressure chamber in response to an input of a drive signal. The output processing portion causes the piezoelectric element to output a first electric signal corresponding to vibration generated in the pressure chamber in response to the input of the drive signal to the piezoelectric element. The determination processing portion determines whether or not the pressure chamber is in a filled state in which the pressure chamber is filled with the liquid, based on a frequency of the first electric signal output by the output processing portion.
