TL;DR: In this paper, a model based on a one-dimensional heat conduction equation, an equilibrium pressure-temperature relation, energy and mass conservation relations and a hydraulic equation was proposed for bubble jet printing.

TL;DR: In this paper, an electron-beam generating device, in which a number of cold cathode elements are matrix-wired, as well as a method of driving the device, is applied to an image forming apparatus.

TL;DR: In this article, a model based on the classical nucleation theory was developed to predict the nucleation process in bubble jet printers and the results provided a new guide to the design of bubble jet printer.

TL;DR: A liquid jet method for ejecting liquid using a bubble created by heating the liquid in a passage, characterized in that a non-dimensional number Z which is determined by the nature of the liquid, a heat flux and a configuration of the passage and which is specific to a recording head is not less than 0.5 and not more than 16 as mentioned in this paper.

TL;DR: A liquid jet recording method includes applying thermal energy to liquid in a liquid passage to produce film boiling of the liquid to produce a bubble; permitting the bubble to communicate with ambience; wherein the liquid passage is not blocked in the communicating step as mentioned in this paper.
