摘要:
A droplet ejection head includes a nozzle plate that has nozzles and includes a polymer material. The polymer material forming the nozzle plate includes a lubricant having an average particle size of not smaller than 0.01 μm and not larger than 8% of a hole diameter of each of the nozzles.

A method of manufacturing an ink jet recording head. On one and the other surfaces of an ink supply plate, formed with a plurality of discrete ink supply ports and a corresponding number of discrete nozzle ports, a green sheet for a pressure chamber plate and a green sheet for an ink pool plate are laminated, respectively. The resulting lamination is then sintered. A vibration plate is subsequently adhered to the pressure chamber plate formed by the sintering step and a nozzle plate is adhered to the sintered pool plate.

A photovoltaic cell in accordance with the present invention includes at least a metal layer, a semiconductive layer and a transparent electrode formed on a substrate. The metal layer is composed of a metal mainly containing aluminum; and has an x-ray diffraction pattern in which a (111) peak intensity is enhanced to at least 2.1 times a (200) peak intensity, at least 4.4 times a (220) peak intensity and at least 4.1 times a (311) peak intensity. The metal layer essentially consists of an aluminum-titanium alloy or an aluminum-magnesium alloy. An interlayer may be provided between the metal layer and the substrate.
摘要:
A process for stably producing a zinc oxide thin film by electrolysis with excellent adhesion to a substrate is described. In particular, a zinc oxide thin film suitably used as a light confining layer of a photoelectric conversion element is formed on a conductive substrate by applying a current between a conductive substrate immersed in an aqueous solution containing at least nitrate ions, zinc ions, and a carbohydrate, and an electrode immersed in the solution.
