To supply a liquid at a stable concentration, a liquid container includes a liquid container bag which contains a liquid, a spacer member which is disposed inside the liquid container bag, liquid introducing portions which are disposed in the spacer member and introduce the liquid, a liquid delivery member which is fixed to one end portion of the liquid container bag and delivers the liquid introduced from the liquid introducing portions to a liquid ejecting apparatus, and a low rigidity portion which changes heights of the liquid introducing portions along with deformation of the liquid container bag.

Liquid container and liquid ejecting apparatus

The method of manufacturing a liquid ejection head according to the invention includes a bonding step, that is, a step of placing a plurality of element substrates on an adhesive layer formed on a bonding surface and heating the adhesive layer to bond the element substrates to a base material. The bonding step is started from one or two of a plurality of bonding regions located at the center portion of the base material in an arrangement direction of the element substrates and then performed toward the bonding regions located at both end portions of the base material.

A sheet processing apparatus includes a processing table to which a printed sheet is transported, a positioning member that positions the sheet, a cutter that cuts the positioned sheet into a binding margin portion and an image portion, and a taping unit that joins the binding margin portion and the image portion together with a tape in a state in which a gap is formed therebetween.

Bookbinding with cutting and re-attaching sheets

An electric connection method for connection between a semiconductor substrate and an electric wiring substrate includes a first process for providing the semiconductor substrate having a heating member and a pad and the electric wiring substrate having first wiring and second wiring, a second process for electrically connecting the first wiring and the heating member, a third process for causing the heating member to generate heat by supplying power to the heating member through the first wiring, and a fourth process for electrically connecting the pad and the second wiring at a temperature higher than a temperature for electrically connecting the first wiring and the heating member.

Electric connection method

There is provided a method of manufacturing a liquid ejection head that includes a supporting member having a major surface provided with a plurality of supply paths, and a recording element substrate having a bonding surface bonded to the major surface and provided with a plurality of supply ports arranged side by side in an arranging direction in which the supply paths are arranged side by side, the supply ports having smaller widths than the respective supply paths in the arranging direction. The method includes applying a bonding agent on the major surface around each of the supply paths, spreading the bonding agent to inner side surfaces of the supply ports by pressing boundary portions between the bonding surface and the supply ports into the bonding agent applied, and bonding the bonding surface to the major surface at a bonding position where the supply ports face the respective supply paths.

A method for manufacturing a fiber absorber includes individuating preformed fibers, compressing the preformed fibers, housing the compressed fibers in a needle-punch processing case in which needle insertion holes are formed, and performing needle punching by inserting needles through the needle insertion holes from at least three directions having perpendicular relation to one another in the needle-punch processing case.

Method for manufacturing fiber absorber

A liquid recording head includes a protective layer having resistance to liquid and an adhesiveness improving film disposed on a second surface of a silicon substrate, opposite to a first surface. The first surface and the second surface have a plane direction (100). The protective layer is disposed in a peripheral region of an opening of a liquid supply port. A liquid ejection chip is bonded to a head substrate with an adhesive so that the liquid supply port communicates with a liquid introduction port on a side of the second surface of the silicon substrate.

A method of manufacturing a liquid ejection head includes: defining a first imaginary reference line along the longitudinal direction of a base member and measuring the distances between the first imaginary reference line and at least two liquid supply port portions of a liquid supply port row, including defining a second imaginary reference line passing the liquid supply port portion at the shortest distance from the first imaginary reference line and the liquid supply port portion at the longest distance from the first imaginary reference line respectively from among the at least two liquid supply port portions and defining the second imaginary reference line between two imaginary lines parallel to the first imaginary reference line.

Method of manufacturing liquid ejection head and liquid ejection head

The ink jet cartridge includes a tank case that has a space having a opening, a lid that closes the opening, an ink accommodating section that is formed with the space of the tank case and the lid, and an ink absorber that is accommodated in the ink accommodating section. Also, an atmosphere communication port that passes through the lid and a projection section that projects to the space of the tank case are provided in the lid. The ink absorber consists of a fiber aggregate, and a welding section in which the fibers are combined to each other and an unwelded section in which the fibers are not combined to each other are provided on a surface that faces the lid.
