    Abstract: Disclosed herein is a liquid discharging method, comprising using a liquid-discharge head equipped with a discharge opening from which a liquid is discharged, a first region to which a first liquid is supplied, a bubble-generating region containing a second liquid and generating bubbles in the second liquid, and a movable member which is displaceable between a first position opposite to the bubble-generating region and a second position within the first region and apart from the bubble-generating region and has a support part more upstream than its free end, in which the movable member is displaced from the first position toward the second position with the generation of a bubble in the bubble-generating region, and the bubble is guided to the discharge opening by the movable member, wherein the first liquid and the second liquid have no compatibility with each other.

    Abstract: A method for manufacturing a component provided with a number of liquid paths having movable members for use of liquid discharging comprises the steps of displacing the movable members provided for thin film material by use of such thin film material having the movable members on it, and a component provided with a plurality of recessed portions, and of placing the movable members, which are in the state of being displaced with respect to the recessed portions of the component correspondingly, hence making it possible to fabricate a liquid jet head without damaging or deforming such thin film material constituting the movable members. With the provision of the movable members, the discharging power and efficiency of the liquid jet head are significantly enhanced to obtain recorded images of high quality at higher speeds.

    Abstract: A method for manufacturing an orifice plate used for a liquid discharge provided with discharge port for discharging liquid comprises the steps of preparing a non-conductive plate having recessed portion formed on the circumference of the flat portion corresponding to the discharge port, forming a first conductive material peelable from the non-conductive plate only in the recessed portion of the non-conductive plate, forming a plate member by plating the first conductive material with a second conductive material by electroforming method after the formation of the first conductive material, and obtaining the orifice plate having the discharge port by peeling off the plate member from the non-conductive plate. With the method thus arranged, it is possible to materialize the same precision as in the glass mask used for photolithography, and make the variation of orifice areas smaller for the formation of highly densified orifices.

    Abstract: A liquid discharging head comprises a discharge opening for discharging a liquid, a bubble generation region for generating a bubble in a liquid, and a movable member disposed so as to face the bubble generation region and arranged as displaceable between a first position and a second position more distant from the bubble generation region than the first position, wherein the movable member has the narrowest space in the bubble generation region and is displaced from the first position to the second position by pressure based on generation of the bubble in the bubble generation region, and wherein the bubble is made to expand greater downstream than upstream with respect to a direction toward the discharge opening, by displacement of the movable member.
