摘要： A liquid discharge head includes a nozzle, an individual liquid chamber, and a circulation channel. The nozzle discharges liquid. The individual liquid chamber is communicated with the nozzle. The circulation channel is communicated with the individual liquid chamber. A first direction in which liquid flows in the individual liquid chamber crosses a second direction in which liquid flows in the circulation channel. A liquid-inflow-side opening of the nozzle faces an area in which a flow of liquid changes from the first direction to the second direction.

摘要： A liquid ejection head includes a nozzle plate, a channel plate, a common-liquid-chamber member, and a deformable damper area. The nozzle plate includes plural nozzles to eject droplets of liquid. The channel plate includes individual liquid chambers communicated with the nozzles. The common-liquid-chamber member includes a common liquid chamber to supply the liquid to the individual liquid chambers. The deformable damper area forms a wall face of the common liquid chamber. The channel plate has an end in a direction perpendicular to a nozzle array direction in which the nozzles are arrayed. The end is opposed to a portion of the damper area and has a relief at a side facing the damper area to permit deformation of the damper area.

摘要： An object of the invention is to provide a plating pretreatment solution that can convert the surface of an aluminum substrate for hard disk devices into a surface suitable for electroless nickel plating, and a method for producing an aluminum substrate for hard disk devices using the same. The plating pretreatment solution of the present invention used for a plating pretreatment in production of an aluminum substrate for hard disk devices has an iron ion concentration of 0.1 g/l to 1.0 g/l and a nitric acid concentration of 2.0 wt % to 12.0 wt %. This plating pretreatment solution is used for a pretreatment of a plating step in which electroless nickel plating is applied to an aluminum substrate for hard disk devices. Accordingly, the surface of the aluminum substrate for hard disk devices is converted into a surface suitable for electroless Ni plating, and a smooth surface of a plated film is obtained by suppressing generation of waviness, nodules, and pits on the plated surface when electroless nickel plating is performed in the plating step.
