Abstract: A laser processing method comprises at least one of a laser light source, a beam shaping optical system for shaping laser beams, a mask having specific patterns corresponding to the processing configuration of a work, an illumination optical system for illuminating the mask, and a projection optical system for focusing the pattern images of the mask on the processing surface of the work by a specific magnification. This mask is provided with an extinct portion smaller than the quotient of the resolution and specific magnification of the projection optical system. With the method thus arranged, a work can be processed to provide complicated three-dimensional grooves having irregularities in the direction of laser irradiation by one-time processing. Also, the extinct portions make it possible to easily and finely adjust the extinction so that the precision of work processing is enhanced.

Abstract: A common recess, grooves, and common recess and/or column members in the grooves are formed on a base board at the same time, and such board is made a second base board, which is coupled to a first base board on which elements for liquid discharging energy are formed; hence obtaining an ink jet recording head provided with a filter unit in an arbitrary position in the region formed by the ink paths and the common liquid chamber. The filter unit can be processed by a single processing in the ink paths and/or the common liquid chamber to make it possible to prevent disabled discharge from taking place due to dust particles intermingled at the time of head manufacture. In this way, the discharging stability is enhanced, making a high-speed printing possible. A work is efficiently processed by a single processing which is performed to process a three-dimensional configuration with respect to the direction in which the laser beam is irradiated.

Abstract: An apparatus and method for correcting printing characteristics of a full-line printhead, and producing a high-printing quality printhead at high manufacturing yield, a corrected printhead by this apparatus, and a printer employing this printhead. According to this method, an image is printed on a printing medium by using double pulses obtained based on fluctuation of resistance of each printing unit of a printhead, and a reference OD value is determined from an OD value histogram of the printed image. A preheating pulse width is selected, based on OD values of n printed images obtained by changing the preheating pulse width n times and the reference OD value, such that an OD value on each printing element is equal or close to the reference OD value. For example, assuming that the reference value is 0.43, a preheating pulse width on printing element No. 3 is 0.875 mu sec.

Abstract: A method for manufacturing liquid jet recording heads, each provided with discharge ports (2g) to discharge liquid, a discharge port plate (2b,21) having the discharge ports arranged therefor, and performing ablation processing of holes becoming the discharge ports by use of a mask (12) for projecting the image of the mask onto the discharge port plate with coherent laser beam (L) as light source, comprises the following steps of forming water-repellent layer (22) on the surface of the discharge port plate (2b,21) on the liquid discharge side; and of performing the ablation processing by irradiating the laser beam from the reverse side of the surface of discharge port plate having the water-repellent layer formed thereon in a state of such surface being arranged to be under the atmosphere containing fluorine atom, and forming the discharge ports, at the same time, enabling the substance containing the fluorine atom excited by the laser beam (24) to adhere to the surface having the water-repellent layer formed thereon. In this manner, the throughput of product manufacture is enhanced without any provision of extra processing steps to remove the byproducts to be created by the irradiation of laser beam, hence contributing to a significant cost reduction of the manufacture of liquid jet recording heads.
