Abstract: PURPOSE:To perform reliably adjustment of the position between a top plate and a heater board by holding a gap between the top plate and fingers at a predetermined space. CONSTITUTION:A top plate member 104 is grasped by fingers 26b, 26c. By moving the fingers 26b, 26c, the top plate member 104 is set on a heater board 102 with bonding agents 80a, 80b therebetween and, in this setting state, the grasp by the fingers 26b, 26c is released. The fingers 26b, 26c are made engageable with an ink injection part 118 of the top plate member 104 from the lateral direction of the injection part and are moved in the lateral direction to abut against the ink injection part, thereby adjusting the relative position between each heater 112 of the heater board 102 and each nozzle 106 of the top plate member 104.

Abstract: PURPOSE:To drastically improve working efficiency by comparing measured machined positions with the corresponding positional reference values to obtain an amount of deviation between the machined position and the positional reference value and moving a work based on the amount of deviation. CONSTITUTION:The central position of two beam fluxes with which the machining surface is irradiated is decided as the positional reference value. Each of the machining positions on the machining surface of the work W which is irradiated with two beam fluxes is measured by using measuring optics systems 70, 80. The measures machining positions are compared with the corresponding positional reference values to obtain an amount of deviation between the machining position and the positional reference value. The work W is moved based on the amount of deviation obtained. In this way, the machining positions with respect to the beam fluxes corresponding to the plural holes to be machined can be aligned concerning plural machining positions at the same time.

Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a liquid jet recording head in which recording liquid jetting performance can be enhanced by making thin a resin layer forming a jet port thereby increasing the opening area of the jet port. SOLUTION: An injection molded jet port plate 11 is recessed on the side abutting against an element board 17 on which a jet energy generating element 16 is formed by irradiating with a laser beam L to form a step part 15a. The liquid channel 13 in a top plate 10 is then aligned with the jet energy generating element 16 and the top plate 10 is jointed to the element board 17 while abutting the end face thereof against the jet port plate 11 through the step part 15a. According to the structure, the opening area of a jet port 12 can be increased by making thin a resin layer forming the jet port 12 and the distance between the jet port 12 and the jet energy generating element 16 can be shortened.

Abstract: PROBLEM TO BE SOLVED: To provide the laser beam machining method capable of easily and correctly machining a fine and complicated shape by irradiating the laser beam. SOLUTION: In the case of machining with the laser beam projections 6 in the joining surface of plural channel grooves 3 and groove walls 4 between channel grooves or the like in a second substrate 1 constituting a liquid jet recording head, first, projections 6 are machined and formed by irradiating the laser beam via a first mask pattern 10 having a high spatial frequency consisting of transmitting parts 11 and shielding parts 12 for machining projections 6, thereafter, channel grooves 3 are machined and formed by irradiating the laser beam via a second mask pattern 14 having a low spatial frequency consisting of transmitting parts 15 and shielding parts 16 for machining channel grooves 3. Whereby, the generation of the by-product in laser beam machining is reduced, the influence of the by-product on machining is also reduced even when the by-product in laser beam machining intervenes, and the fine and complicated shape is stably and correctly machined.
