    摘要： In a liquid injection recording apparatus wherein recording liquid is discharged from discharge ports provided in the discharge port surface of a recording head to make flying liquid droplets to thereby accomplish recording, liquid-repellent process means capable of applying a liquid-repellent agent for repelling the recording liquid adhering to the discharge port surface is provided to the discharge portion surface from a position capable of being opposed to the discharge port surface.

    摘要： A fluid ejection head comprises a heater disposed in a fluid path. A bubble is generated by supplying electric power to the heater, and ink is ejected in a direction substantially parallel to a face of the heater. The fluid path is shaped to have a first part with a constant-sectional area adjacent to an ejection orifice a second part located behind the first part and containing the heater. The cross-sectional area of the second part increases by twice as large as the cross-sectional area of the ejection orifice, a length (A) between an end of the first part of the fluid path and a top end of the heater is greater than or equal to half of the height Ph of the ejection orifice, and a shortest gap between the ejection orifice and the heater is less than or equal to a sum of a half of the height Ph of the ejection orifice and a length (L) of the first part of the fluid path.

    摘要： An ink jet recording head comprises a discharging opening for liquid discharge and an electricity-heat convertor. The electricity-heat convertor comprises a heat-generating resistor and electrodes attached to the resistor. The heat-generating resistor and electrodes are formed from a single layer of electroconductive material which is anodically oxidized to change it into an insulating material except in the region where the resistor and electrodes are located. The resistor is formed by anodically oxidizing a portion of the layer which remained electroconductive after the first anodic oxidation to obtain a desired resistance value.

    摘要： An ink jet recording head having a discharge port for discharging ink therethrough comprises a liquid path communicating with the discharge port having a portion in which energy available for discharging the ink acts on the ink, an energy generating member for generating discharge energy, a liquid chamber capable of storing the ink therein and in which the opening portion of the liquid path is provided, and a pair of communication holes for communicating the interior of the liquid chamber with the outside thereof, at least a portion of the ceiling of the liquid chamber is provided at a level higher than the ceiling of the liquid path. Liquid flows in one of the communication holes as a liquid flow inlet and the liquid flows out the other communication hole as a liquid flow outlet. There is provided a guide wall which, when a flow of the liquid is formed between the communication holes, provides a hindrance to the liquid flow rectilinearly linking the communication holes together and guides the flow of the liquid toward the opening portion of the liquid path in the liquid chamber.
