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： A head drive control unit generates and outputs a pulse formed of a first expansion waveform element to expand individual liquid chambers, a first contraction waveform element to contract the individual liquid chambers, a second expansion waveform element to expand the individual liquid chambers, and a second contraction waveform element to return the individual liquid chambers that have repeatedly expanded and contracted to an initial state. The first contraction waveform element serves as a waveform element that contracts the individual liquid chambers at a timing of resonance with a change in a pressure in the individual liquid chambers due to the first expansion waveform element. The second contraction waveform element serves as a waveform element that suppresses the change in the pressure in the individual liquid chambers.

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.
