摘要： 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.

摘要： A method for manufacturing a liquid-discharging recording head can prevent deviation in the dimensions and the pitch of grooves, serving as liquid channels, and holes, serving as discharging ports, and generation of burrs around discharging ports while maintaining the grooves and the holes to desired sizes and without increasing a time required for the processing when forming the grooves and the holes by projecting a laser beam. When performing ablation processing of the liquid-channel grooves or the discharging ports in a top-plate blank by projecting the laser beam, the processing is performed by changing the energy density per unit time of the laser beam continuously or stepwise by adjusting the oscillation voltage or the oscillation frequency of the laser beam, attenuating the laser beam, or moving a substance to be processed along the optical axis.

摘要： A liquid jet recording head comprises a first substrate having a plurality of discharge energy generating devices formed thereon, and a second substrate having a discharge opening plate provided with a plurality of discharge openings for discharging ink, and recessed portions becoming ink flow paths conductively connected with said discharge openings, and a common liquid chamber for retaining ink to be supplied to each of said discharge openings, respectively. The ink flow paths and common liquid chamber are formed by joining the first substrate and second substrate with the discharge energy generating devices of the first substrate facing the recessed portions becoming ink flow paths of the second substrate, at the same time, the joint between the first substrate and second substrate being sealed by sealing compound, and fine grains inclusively residing on the joint between the first substrate and second substrate. With the liquid jet recording head thus structured, there is no possibility that sealing compound flows into the ink flow paths and discharge openings even if the joint between the first and second substrates are sealed by sealing compound, and that any defective prints take place. The production yield in the sealing step of manufacture is increased, at the same time, the controlling burden is lightened.

摘要： A laser processing apparatus is provided with a light source to generate laser beam, a lens to guide laser beam to a predetermined portion of a blank that becomes a structural member of a liquid jet recording head, a split prism arranged on the optical path between the light source and the lens. This laser processing apparatus is arranged to further include a rotary mechanism capable of rotating the lens centering on the optical axis of the laser beam. With the structure thus arranged, it is possible to prevent the lens from being locally damaged by the irradiation of laser beam, thus making the life of the lens longer, while reducing the frequency of lens replacements. This arrangement leads to the implementation of a significant reduction of maintenance costs of the apparatus, as well as to the simplified manufacture of a liquid jet recording head at lower costs.

摘要： A laser working method which can easily and accurately work a fine and complicated shape by irradiation of a laser beam is provided. When a plurality of channel grooves are laser worked on a second board constituting a liquid jet recording head and projections are laser worked on the joint surface of groove walls between the channel grooves and the like, the projections are first worked and formed by irradiating the laser beam through a first mask pattern of a high space frequency arranged by transmitting portions to work the projections and light shielding portions. After that, the channel grooves are worked and formed by irradiating the laser beam through a second mask pattern of a low space frequency arranged by transmitting portions to work the channel grooves and light shielding portions. The formation of a secondary product due to the laser working can be reduced. Even when the laser working secondary product exists, the influence by the secondary product can be reduced and the working can be performed. A fine and complicated shape can be stably and cheaply worked.

摘要： A method for manufacturing liquid jet recording heads, each provided with discharge ports to discharge liquid, a discharge port plate having the discharge ports arranged therefor, and performing ablation processing of holes becoming the discharge ports by use of a mask for projecting the image of the mask onto the discharge port plate with coherent laser beam as light source, comprises the following steps of forming water-repellent layer on the surface of the discharge port plate 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 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.

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.
