Abstract: PROBLEM TO BE SOLVED: To enhance the tact of a top joint process while simplifying an apparatus by eliminating the butting process of the apparatus at the time of butt joint where a top plate is secured while aligning the nozzle position with a heater by butting the butt reference of the top plate against HB end face. SOLUTION: In a butt joint process, side face of a top plate is not pressed by a jig on an apparatus but pressed by applying the turn up part (being hooked to BP) of a fixing member (spring). Similar effect is aimed by providing a bend at the foot of the fixing member.

Abstract: PROBLEM TO BE SOLVED: To position a substrate and a metal thin film layer simply and accurately in a short time without the need of a large and expensive apparatus. SOLUTION: A metal thin film layer 4 having a valve member 48 integrally formed is disposed on a substrate 2 having an ink channel 1 formed so that magnetic attraction is generated from a side thin film magnetic head 5a to the metal thin film layer 4. The metal thin film layer 4 is moved until being contacted with the thin film magnetic head 5a so that the magnetic generation from the thin film magnetic head 5a is stopped. Subsequently, magnetic attraction is generated from a rear thin film magnetic head 5b. The metal thin film layer 4 is moved until being contacted with the rear thin film magnetic head 5b so that the magnetic generation from the thin film magnetic head 5b is stopped. Accordingly, the metal chin film layer 4 is positioned horizontally with the magnetic heads 5a, 5b provided on the substrate 2 as the reference.

Abstract: PROBLEM TO BE SOLVED: To provide a recording head correcting device, which surely and quickly corrects a recording head, and a recording head correcting method and provide the recording head, the recording characteristics of which are corrected by the above-mentioned device, and a recording device employing the corrected recording head. SOLUTION: By applying n kinds of recording controlling signal patterns to a full line recording head, recording patterns are recorded n times on trial. A standard concentration distribution is formed from one of recording pattern images for n trial times, resulting in selecting one among n kinds of the recording controlling signal patterns for every recording elements so as to be equal or akin to the standard concentration distribution. However, in order to verify whether the selected recording controlling signal is the optimum signal or not, the similar selection is performed to another standard concentration distribution formed on the basis of other recording pattern images so as to adopt the optimum one among a plurality of recording controlling signal patterns as correction data.

Abstract: PROBLEM TO BE SOLVED: To provide an ink jet head applied with an aligning method of higher accuracy, a manufacturing method thereof, a printer mounting the ink jet head and an information processor. SOLUTION: Central position A1 of the gap between first and second substrates is measured when viewed from the face of the substrate arranged with an array of energy generating elements. A correction value C for calculating the target aligning position of a top plate is then determined from the central position A1 and the central position A2 of the gap between the first and second substrates is measured when viewed from the ink ejecting direction. The central position A2 is corrected with the correction value C to determine an alignment target value D=A2-C. Furthermore, the central position E of the alignment reference hole in the ink ejection face of the top plate is measured and the shift F=D-E of the central position E of position reference hole from the alignment target value D is determined. The top plate is moved such that the absolute value of F will be equal to or smaller than a specified value.

Abstract: PROBLEM TO BE SOLVED: To shorten a registration time for members constituting an ink-jet printer head and simplify an apparatus. SOLUTION: An orifice plate 1 is provided which has a magnetic layer 1-a partly on a face or on the entire face. A position information recorded to the magnetic layer 1-a is detected, thereby positioning members constituting an ink-jet printer head. The ink-jet printer head is manufactured in this method. The ink-jet printer head has position information recorded at the magnetic layer 1-a for positioning members constituting the head.
