Liquid discharge head and method for manufacturing the same

A liquid ejection head is constituted by a substrate provided with a plurality of energy generating elements used for ejecting a liquid and a plurality of liquid supply ports for supplying the liquid, and a plurality of flow passage forming members, disposed on the substrate, provided with a plurality of ejection outlets for ejecting the liquid supplied from the liquid supply ports and a plurality of flow passages for establishing communication between the liquid supply ports and the ejection outlets. One of the flow passage forming members for forming one of the flow passages for establishing communication with one of the ejection outlets and another one of the flow passage forming members for forming another one of the flow passages for establishing communication with another one of the ejection outlets are independently provided.

Liquid ejection head and production process thereof

The present invention provides a durable liquid housing container and a durable liquid supply apparatus which use a gas-liquid separation membrane. Thus, a gas-liquid separation membrane () located at an air vent in a liquid housing container () includes a fibril portion (A) composed of fibrous portions and an annular node portion (B) which bundles the ends of fibrous portions of the fibril portion (A) and which is closed so as to surround the fibril portion (A).

Liquid housing container and liquid supply apparatus

A liquid discharge head including a discharge element substrate including an orifice plate having a discharge port for discharging a liquid, and a supply port opened in the reverse side of the surface forming the discharge port for supplying a liquid into the discharge port; a support member having a supply path for supplying a liquid into the supply port; and a flexible wiring substrate having a blanking portion for transmitting a signal for discharging a liquid to the discharge element substrate. The discharge element substrate is electrically connected to the flexible wiring substrate on the surface opening the supply port, the flexible wiring substrate is bonded to both the discharge element substrate and the support member by means of an adhesive, the end face of the blanking portion is covered with the adhesive, the covered blanking portion communicates with the supply port, and the adhesive is a thermally fusible adhesive composed of denatured polyolefin, having a softening point of 80&#xb0; C. or higher.

The present invention has as its object to provide a pattern forming method which, even if a pattern is formed by photolithography, can keep the edge of the opening portion of the pattern in a sharp state and yet, can make the wall surface of the recess of the pattern into a tapered shape, and a method of manufacturing an ink jet recording head to which the aforedescribed method is applied. The pattern forming method is a pattern forming method having the step of forming on a substrate a coat resin layer containing a photopolymerizable resin, the step of applying a solution containing a photopolymerization starting agent onto the coat resin layer, and forming the distribution of the density of the photopolymerization starting agent in the direction of film thickness of the coat resin layer, and the step of applying light from above the coat resin layer through a mask having a pattern depicted thereon, and the step of developing the coat resin layer to which the light has been applied to thereby make it into a coat resin layer having the pattern, and this method is applied to the manufacture of an ink jet recording head.
