摘要： A liquid discharging method comprises the step of displacing the free end of the movable member following the creation of air bubble in the air bubble generating area. For this method, the fulcrum of the movable member is positioned on the side different from liquid discharging side with respect to the displacement area for the free end of the movable member to be displaceable, and at the same time, the free end thereof is arranged to face the effective bubbling area positioned on the downstream side of the central portion of the length of the effective bubbling area that forms the bubble generating area in the direction of the movable member from the fulcrum to the free end thereof, and a part of the effective bubbling area positioned to face the free end of the movable member on the downstream side of the effective bubbling area is arranged to face the displacement area directly. Thus, the initiation of the displacement of the free end of the movable member is effectuated quickly and reliably, and the pressure exerted by the air bubble creation is led to the discharge port side and the fulcrum side of the movable member sufficiently at the time of bubbling, and the development of air bubble that follows is directed to the discharge port side more reliably and efficiently.

摘要： A method of manufacturing a liquid discharge head having a liquid flow path, a discharge energy generating device in the liquid flow path, a discharge port communicating with the liquid flow path, and a movable member facing the discharge energy generating device. The movable member is formed by a photolithographic technique, and a right-angled part and an acute-angled part of an edge of the movable member are removed so as to make a surface of the edge of the movable member curved. The curved surface of the movable member serves to reduce concentration of the stress on the movable member that occurs due to displacement of the movable member resulting from pressure of a bubble generated to discharge ink. Removal of the right-angled and acute-angled parts may be performed by soaking the movable member in an etching solution after formation of the movable member.

The flow path is formed by joining a substantially flat substrate including the heat generating body and the movable member to a top plate opposed to the substrate and including the regulating portion and the liquid is discharged from the discharge port by energy generated by generation of the bubble. When both a volume change ratio of the bubble and a displacement volume change ratio of the movable member tend to increase, the displacement of the movable member is regulated by the regulating portion.

摘要： A liquid discharge head comprises heating members for generating thermal energy to create bubbles in liquid, discharge ports forming the portions to discharge the liquid, liquid flow paths communicated with the discharge ports, at the same time, having bubble generation areas for enabling liquid to create bubbles, movable members arranged in the bubble generation areas to be displaced along with the development of the bubbles, and regulating members to regulate the displacement of each of the movable members within a desired range, and with energy at the time of bubble creation, the liquid being discharged from the discharge ports. For this liquid discharge head, each of the liquid flow paths holds bubbles at the time of bubbling, at the same time, being provided with gaps arranged on the sides of the movable member to allow the liquid on the upstream thereof to flow into the bubble generation area at the time of bubble disappearing. With the structure thus arranged, the meniscus is drawn into the liquid flow path quickly immediately after the bubble disappearing of bubble begins, and then, with a strong force of the meniscus, the trailing portion of the liquid column connected with the discharged droplet is cut off outside the discharge port, hence making the number of satellites smaller for the enhancement of the quality of prints.

摘要： The invention is to vary the amount of the liquid discharged from a same discharge port, thereby realizing recording of multi gradation levels. After the discharge of a first liquid droplet 66a, a second liquid droplet 66b is discharged while the movable member 31 is still in a displaced state. In comparison with the first liquid droplet 66a, the second liquid droplet 66b has a larger discharge energy and a larger speed, because the moving energy of the movable member 31 and the energy consumed for the liquid flow opposite to the discharge port 18 are small. Thus the first and second droplets are united to form a united droplet 66d before landing on the recording medium 150. In this manner the amount of the discharged liquid can be varied.
