摘要： A method for producing a substrate for an ink jet recording head comprises preparing a substrate with plural heat generating resistors for applying heat to the ink, plural wirings electrically connected thereto, and plural heat generating areas formed by the heat generating resistors exposed from the wirings, coating the heat generating resistors and the wirings on the substrate with a first insulating protective film, removing the first insulating protective film by wet etching in portions on the heat generating areas, and coating thus etched first insulating protective film with a second insulating protective film, wherein the etched portion of the first insulating protective film, in the longitudinal direction of the heat generating area, is positioned inside from the end of the heat generating area, by at least 1/2 of the thickness of the first and second insulating protective films covering the wirings.The protective film is thus made thinner on the heat generating areas, thus reducing the electric power consumption while maintaining sufficient durability.

摘要： A method for manufacturing an ink jet recording head by combining each of the processes to fabricate a heater board comprises (I) the first step of patterning a resistive layer on a substrate, (II) the second step of laminating a first protection layer and patterning the protection layer to form a groove by removing an area for wiring electrode layers to be formed later, (III) the third step of laminating a layer formed by material for use of the wiring electrode layers, (IV) the forth step of continuously giving heat treatment to the surface of the substrate, while the surface is not allowed to be exposed to the air outside, to enable the layer formed by the material of the wiring electrode layers to flow into only the groove on the first protection layer provided in the first step, and making the surface flat, as a result of which, a pair of electrode layers are formed to enable the resistive layer between them to be constituted as the heat generating unit and (V) the fifth step of forming a second protection layer. With this method of manufacture, it is possible to provide an ink jet recording head whose power dissipation is small, while having a good durability and capability of recording in high quality.

摘要： An ink jet head has a first member having a plurality of energy generating elements for generating energy necessary for ejecting ink, a second member having a plurality of grooves separated by land portions, the grooves constituting an array of ink channels leading to an array of ink ejecting openings and the land portions constituting ink channel walls separating the ink channels, and a pressing member for pressing the first member and the second member to each other, thereby joining these members so that the ink channels are formed by cooperation between the first member and grooves in said second member. The height of ink channel walls is varied such that it is smaller at both end regions of the array of ink channels than at the central regions of the array of ink channels. Close and tight contact between the first member and the second member is attained in the central region of the ink channel array where the ink channels actually perform ejection of ink, so that ink can be discharged accurately without any crosstalk between adjacent ink channels, thus ensuring high quality printing.

摘要： In a liquid discharge head having a movable member displaced by generation of a bubble, endurance of stepped portions of the movable member and of root portions of movable parts of the movable member is enhanced and flexure deformation of the movable member is prevented to enhance endurance of the member. A pressing member for covering stepped portions of a movable member and root portions of branched movable parts is provided within a flow path. A part of the pressing member is tapered and extends to a downstream side (toward a discharge port) to be spaced apart from the movable member, thereby forming a flexure regulating portion opposed to and spaced apart from an intermediate portion of the movable member. The pressing member and the flexure regulating portion suppress excessive deformation of the movable member.
