Abstract: PROBLEM TO BE SOLVED: To accurately, effectively and simply displace at liquid passages by providing the step corresponding to a recess in the state that a movable member of a thin film material is displaced from the material by using a component having the material including many movable members and many recesses corresponding to the passages. SOLUTION: A movable member 31 is provided at a position opposed to a downstream side part to bubble 40 generated by heating of a heater 2. Part of liquid filled in a bubble generating region 11 is heated by the heat to generate bubble as a membrane boils. At this time, the member 31 is displaced to introduce its pressure propagating direction to a discharge port direction by pressure based on the generation of the bubble 40. A free end 32 of the member 31 is disposed at a downstream side, a fulcrum 33 is disposed at an upstream side, and at least part of the member 33 is opposed to a downstream part of the heater 2. The member 31 is gradually displaced in response to growth of the bubble 40, and hence bubble growing direction can be uniformly directed to the discharge port to enhance its discharging efficiency.

Abstract: PROBLEM TO BE SOLVED: To make it possible to print a density irregularity-free and high quality level image by comparing the density of the image with a reference density per specified unit, based on the density distribution of the image recorded experimentally and selecting a signal of the type close to the reference density to be sent to a printing head. SOLUTION: When correcting plural recording elements and a recording head IJH with data storing memory 13, plural various signals are applied to the recording elements to make a recording medium record plural recording patterns experimentally. Further, a recording pattern image recorded is read using a CCD camera 4 and one signal is selected from among the plural various signals based on the density distribution of the image so that the recording pattern image is of a value equal to a reference density per specified unit of the recording element. Data for selecting this signal is used as correction data and is stored in memory 13 as initial correction data. After that, either of optical correction data per specified unit of the recording element or the initial correction data is selected, and data based on the selected data is sent to the recording head IJH.

Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a liquid jet recording head in which abutting characteristics between the jet port plate of a top plate and an element substrate can be enhanced without causing any damage on the surface of the jet port plate. SOLUTION: Surface of the jet port plate 2 of a top plate 1 constituting a liquid jet recording head is measured by laser displacement gauges 10a, 10b. Based on a measurement data, abutting pins 11a, 11b pushing the rear end of an element substrate 3 having a plurality of jet energy generating elements 4 are moved such that the liquid jet side end face of the element substrate 3 will be in parallel with the jet port plate 2. Subsequently, the liquid jet side end face of the element substrate 3 is abutted against the jet port plate 2 and the top plate 1 is aligned with the element substrate 3. According to the structure, the jet port plate 2 can be abutted against the element substrate 3 surely without causing any damage on the jet port plate 2.

Abstract: PROBLEM TO BE SOLVED: To manufacture a highly accurate and reliable liquid jet recording head in which alignment can be performed accurately at low cost and short tact. SOLUTION: The distance B from the first heater 21a to the cut end face 22 of an element substrate 20 is operated along with the distance A from the first channel trench 11a to a abutting reference 13 of a top plate 10. Positional shift is then measured under actually aligned state and a correction value E calculated from the distribution thereof is fed back to operation results C thus determining a correction return amount C+E. After the abutting reference 13 of the top plate 10 is abutted against the cut end face 22 of the element substrate 20 by means of a push-in jig 31, the top plate 10 is moved reversely to the element substrate 20 by a return jig 32 based on the correction return amount thus aligning the top plate 10 and the element substrate 20.

Abstract: PROBLEM TO BE SOLVED: To enable highly accurate position correction and efficient registration without being influenced by irregularities of process accuracy of a collet or cut accuracy of an element board, etc., when a base plate and the element board are to be positioned. SOLUTION: After an adhesive 3 is applied to an upper face of a base plate 1 which becomes a mount reference for a liquid-jet recording head, an element board 2 having a row of discharge energy generation elements is supplied onto the base plate 1 by a transfer collet 7. While the element board 2 is held by a position correction collet 8 having a notch 8a, positions of both corner parts 2a of the element board are detected. A shift amount from a target position is finely adjusted and corrected by moving moving means 10-12 for the base plate 1 while the element board 2 is still held by the position correction collet 8, so that the element board 2 is registered. The adhesive 3 is hardened thereafter. Highly accurate positioning and stable mounting can be realized efficiently and a mount Tact is shortened.

Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a liquid jet recording head in which adhesion at a bonding part is stabilized and reliability of ink jet performance is enhanced by pushing the bonding position of the groove part of a top plate and an element board stably and accurately at the end part of a leaf spring member. SOLUTION: A leaf spring member 1 for urging a top plate 3 and an element board 2 constituting a liquid jet recording head set in a fixing jig 17 is moved in the direction of Z axis while being secured to a spring fitting jig 19. Pushing part, e.g. the forward end part, of a leaf spring piece 7 in the leaf spring member 1 is located by means of a proximity sensor 9 and regulated at a preset position thus correcting the positioning. When the leaf spring member 1 is set to the top plate 3 under that state, the part where the groove part 4 of the top plate 3 is bonded to a heater of the element board 2 is pushed accurately regardless of dimensional fluctuation of the leaf spring member 1 and adhesion at the bonding part is stabilized while enhancing the reliability of ink jet performance.

Abstract: PROBLEM TO BE SOLVED: To distribute uniformly an adhesive on an adhesive face by a method wherein a recessed part is provided at a part covered with a separating wall component of a liquid channel forming component, an adhesive is contained in the recessed part, and the separating wall component is fixed. SOLUTION: After obtaining an element substrate 1 equipped with a heating element 2, a coat layer 91 having a recessed part 91 for containing an adhesive 62 fixing a barrier 91a forming a liquid channel and a separating wall 30, is formed on the coat layer of the element substrate 1. Thereafter, a suitable amount of the adhesive 62 considered as an ordinary temperature setting type one which is comparatively little in setting contraction is applied in the recessed part 92, and the separating wall 30 is so positioned that each movable component 31 corresponds to a heating element 2, and bonded. Since the separating wall 30 is supported with the coat layer 91 thereby, the adhesive comes to be contained by a specific uniform thickness in the recessed part 92, and distance between the movable component 31 and the heating element 2 can be kept at a specific distance without any dispersion. Therefore, a stable discharge performance is obtained.
