    摘要： A method for manufacturing an information memory disk comprises a process for preparing a die having an annular first rugged portion corresponding to tracks, and an annular second rugged portion corresponding to a positioning mark and concentrically located against the tracks, a process for manufacturing by the use of the die a blank having an annular rugged tracks (14) corresponding to the first rugged portion and an annular rugged positioning mark (16) corresponding to the second rugged portion, a process for detecting the position of the center of the blank on the basis of the positioning mark, a process for boring a hole (12) centering around the center of the positioning mark (16) through the blank, and a process for forming a light reflecting layer (15) on the annular rugged track.

    摘要： An inkjet head comprises a pressure chamber; a nozzle plate including a first surface at the side of the pressure chamber, a second surface opposite to the first surface, a first nozzle formed into a frustum which penetrates the first surface and the second surface and the diameter of which decreases as it goes closer to the second surface, and a second nozzle formed into a frustum which is the same as the frustum of the first nozzle; and a driving element configured adjacent to the pressure chamber to eject droplets from the first nozzle and the second nozzle simultaneously; wherein the part of the first nozzle on the first surface is integrally connected to the part of the second nozzle on the first surface, and the part of the first nozzle on the second surface is separated from the part of the second nozzle on the second surface.
