摘要:
A liquid discharging method for discharging liquid, which uses the pressure exerted at the time of creating each of bubbles in liquid in a bubble generating area, is arranged to provide two bubble generating areas for generating bubbles in such a manner as to enable these areas to face each other at least partly, hence discharging liquid by means for the pressure thus exerted in the bubble generating areas. In this way, it becomes possible to increase the amount of liquid discharged, as well as to enhance the durability of the movable members, while stabilizing the discharge of liquid from each of the discharge openings.

A manufacturing method for an ink jet recording head, includes preparing a recording element substrate provided with energy generating means for generating energy for ejecting liquid, two opposing sides opposed to each other, an electrode portion disposed along a side sandwiched between the opposing sides to supply electric power to the energy generating means; preparing an electric wiring member provided with wiring leads for supplying electric power to the electrode portion from an outside, the electric wiring member being provided with sides opposed to the opposing sides of the recording element substrate and to the side sandwiched between the opposing sides; forming an electrical connecting portion at least one of the opposing sides by connecting the electrode portion and the wiring lead with each other; providing a gap L1 between one of the opposing sides of the recording element substrate and the side of the electric wiring member opposing the one of the opposing sides, and providing a gap L2 between the other one of the opposing sides and the side of the electric wiring member opposing the other one of the opposing sides, wherein the gap L1 is larger than the gap L2, and wherein the electrical connecting portion is interposed between the gap L1 and the gap L2; and supplying a sealing material in a direction from the gap L2 toward the gap L2 through the electrical connecting portion.
摘要:
An object of the present invention to provide a process for manufacturing a printing head, the process being able to maintain an appropriate connection between a substrate and flying leads. The present invention includes a connecting step of connecting electric connection terminals of a substrate and flying leads provided on an electric wiring basic material and a mounting step of mounting a unit consisting of the electric wiring base material and the substrate connected together, on a printing head main body. During the connecting step, the substrate and each flying lead are electrically connected together with a predetermined distance between them. During the mounting step, the unit is fixed to the printing head main body so that the distance between each of the electric connection terminals of the substrate and the electric wiring base material is shorter than the predetermined distance. This forms a slack shape of each flying lead.
