Abstract: A method for manufacturing an ink jet head. In a thick film laminating step, a patterning layer corresponding to the configuration of ink flow paths on a member provided with a pressure generating source is formed, and an inorganic material layer is overcoated on the patterning layer to form an ink discharge surface. A patterned image of a predetermined ink discharge port configuration is irradiated by a laser capable of completing a sublimate ablation process before the laser beams are dispersed in a work piece as thermal energy. Subsequently, the sublimate ablation process is executed on ink discharge ports almost simultaneously from the inorganic material layer on the ink discharge side up to the interior of the thickness of the patterning layer. The patterning layer is removed after processing the ink discharge ports.

Abstract: A method for forming through holes, which has laser beam as the light source to project the laser beam to the work object using an optical system through a photomask for the formation of through holes on the work object by ablation processing, comprises the steps of increasing the concentration of the optical processing energy contributing to the process using the reflected beam created from the work object in the laser ablation processing; and forming each of through holes having the configuration enabling the narrower end to be changed to the wider end in the incident direction of laser beam. With the structure thus arranged, it becomes possible to increase the energy concentration that contributes to the process as compared with the usual ablation processing, because the reflected beam created in the ablation processing can be utilized again for the optical processing. Then, each of the through holes can be formed easily in the configuration in which the narrower end changes to the wider end in the incident direction of laser beam, which cannot be easily processed by the application of the usual ablation processing.

Abstract: An image can be outputted with a high sharpness without deteriorating a resolution. In order to output an image of a high picture quality while suppressing the occurrence of a moire, an exposure amount is modulated in accordance with pixel density information of the image divided into pixels of a predetermined size by an exposure amount modulating unit in a light scanning unit, thereby expressing an image dark/light state. In this case, in a highlight density region in which a pixel density is equal to or less than ⅓ of the maximum image density, the density data of two adjoining pixels is modulated by one pixel and the other pixel is not recorded. In a density region in which the image density lies within a range from ⅓ to ½ of the maximum image density, a part of the density data of one of the two adjoining pixels is transposed to the other pixel. In a density region in which the image density is equal to or larger than ½ of the maximum density, the pixel transposition is not performed.

Abstract: A plurality of elongated beams are generated by dividing a laser beam, said plurality of beams being respectively applied to corresponding lens elements of a flyeye lens array. The structure is arranged in such a manner that the diameter of the plurality of the beams in the shorter direction is made smaller than that of each of the lens elements, so that the plurality of beams are further divided into a plurality of elongated secondary beams by the flyeye lens. The plurality of the secondary beams are bundled on a diaphragm in such a manner that their lengthwise directions substantially coincide with each other so that a beam pattern is formed. A row of openings arranged in the lengthwise direction of the beam pattern and formed in the diaphragm member are uniformly and efficiently irradiated with the thus-formed beam pattern. Then, the image of the row of openings is projected onto a plastic plate or the like so that a multiplicity of holes are formed in the plate. As a result, a nozzle plate of an ink jet printer head can be accurately and quickly manufactured.
