Abstract: PROBLEM TO BE SOLVED: To highly accurately position and combine a heater board, a top plate and a separation wall of an ink jet head. SOLUTION: A butting reference projection part 7 is formed to a heater board 1. A jig 5 has a butting reference recess part 6 and a groove 9 which regulates a relative position of a separation wall and the jig 5 when a movable part 4 of the separation wall is inserted. In a state while the jig 5 holds the separation wall, the butting reference projection part 7 and the butting reference recess part 6 are butted and registered, whereby the separation wall 4 and the heater board 1 can be registered. A top plate has a butting reference recess part similar to the recess part of the jig, and therefore the top plate and the heater board 1 can be registered in the same method as when the separation wall and heater board are registered.

Abstract: PROBLEM TO BE SOLVED: To align an element board with a top plate while protecting the minute members, e.g. the liquid channel, of the element board and the top plate against deformation or damage. SOLUTION: When an element board 1 having an array of jet energy generating elements and a top plate 2 having a liquid channel part comprising a plurality of liquid channel trenches 2b, a liquid receiving port 2c and a common liquid chamber 2d are assembled while being aligned, compressed air A is supplied from the liquid receiving port 2c of the top plate 2 through a finger for clamping the top plate 2 to form a micro air layer 3 between the element board 1 and the top plate 2. The top plate 2 is moved, while floating, relatively to the element board 1 in order to align a reference jet energy generating element with a reference jet port 2a or a liquid channel trench 2b thus aligning the element board 1 with the top plate 2 while protecting the minute members, e.g. the liquid channel trench, thereof against deformation or damage.

Abstract: PROBLEM TO BE SOLVED: To obtain a measuring method in which a displacement up to an attenuation state is measured on the basis of a sudden change in a diaphragm installed at a liquid discharge head by a method wherein a displacement in one point on the diaphragm and a prescribed displacement amount in which a displacement amount obtained regarding every diaphragm out of a plurality of diaphragms are compared with a prescribed displacement amount which is decided in advance. SOLUTION: When a manual measurement is decided, the initial position of a diaphragm is first confirmed. After that, the measurement is performed along a movement point which is decided in advance by a user. On the other hand, when an automatic measurement is selected, a host computer makes the user confirm the initial position of the diaphragm. After that, the measurement is performed along a measuring point which is decided in advance by the user. When the initial position is displaced due to the mounting operation of a jig or due to an irregularity in the manufacture of a liquid discharge head, the position of a stage is corrected on the side of the user. In this state, a displacement measuring apparatus sequentially measures a plurality of diaphragms constituted on the liquid discharge head. When it reaches a final point, measured data is transferred to the host computer from a converter 11. The host computer judges the displacement amount of every diaphragm on the basis of the data.

Abstract: PROBLEM TO BE SOLVED: To ensure highly accurate temporary positioning at the time of pasting a thin film material to an element board arranged with heating elements by abutting the thin film material against an abutting reference member at a temporary positioning part and then shifting the reference member to a temporary positioning reference position. SOLUTION: When abutting reference members 1a, 1b are previously shifted slightly from the end face of a base 2a, a thin film material P abutting against the abutting reference member 1a, 1b may touch the member 1a, 1b at two points. When the reference member 1a abuts against the base 2a at first, the thin film material P comes into line contact with the member 1a thus ending positioning in the X direction. Subsequently, a part of the material P projecting in the Y direction is pressed against the base 2a by means of the member 1b thus ending positioning in the Y direction. Finally, a microporous medium 3 is deaired and adsorbed thus completing temporary positioning of the thin film material P.
