摘要： An ink-jet head comprising a plurality of sidewalls each imparting a pressure pulse to an ink pressurizing cell by means of shear mode deformation, and a front wall having a plurality of orifices. The ink in the ink pressurizing cells is ejected from the orifices. Each sidewall comprises a first wall section, a first electrode disposed thereon, an anisotropic adhesive disposed thereon, a second electrode disposed thereon, and a second wall section disposed thereon. Width of the first electrode is narrower than width of the first wall section, and the upper surface of the first wall section has first side areas which are not covered by the first electrode. Width of the second electrode is narrower than width of the second wall section, and the lower surface of the second wall section has second side areas which are not covered by the second electrode. The anisotropic adhesive has conductivity only in a direction perpendicular to the upper surface of the first wall section and the lower surface of the second wall section, and the anisotropic adhesive covers the first and second electrodes so that the first and second electrodes are not exposed to the ink in the ink pressurizing cells.

摘要： An ink jet head includes first base (12) second base (14) which are made of a piezoelectric material. The first and second bases are formed with a plurality of first and second grooves in their surfaces, respectively, and are formed with first and second electrodes (36a, 36b) on their surfaces between the first grooves, respectively. The first and second bases also includes side surfaces (12a, 14a) intersecting the surfaces of the first and second bases, respectively. The electrodes are spaced apart from the side surfaces (12a, 14a). The second base (14) is placed on the first base (12) so that the grooves in the first base and the grooves in the second base communicate with each other to define ink pressure chambers (24a, 24b). An insulating layer is formed on the inner walls of the ink pressure chambers (24a, 24b). An orifice plate (25) having orifices (28a, 28b) is bonded to the side surfaces (12a, 14a) so that the ink chambers communicate with atmosphere through the orifices (28a, 28b).

摘要： PROBLEM TO BE SOLVED: To prevent the drying of ink near the orifice of an ink jet head not in use and prevent an injection error of ink by forming a plurality of ink jet heads in a manner of being able to move along their respective shafts and providing a connection member for connecting them in a separable manner. SOLUTION: In an ink jet printer wherein a B head 1 and a YMC head 2 are fixed to a carriage 5, if received print data are a monochromatic document text data, as only the B head 1 is used, the B head 1 and the YMC head 2 are separated by canceling the energization of an electromagnet 21. And then after a prescribed amount of ink is sucked, a cap 9 for the B head 1 is removed by moving a conduit 13 in the direction of an arrow B'. And then dust adhering near the orifice of the B head 1 is removed by moving the sweeping blade 12 in the direction of an arrow B and the carriage 5 in the direction of an arrow A. After that printing is performed while moving the carriage in the direction of arrows A-A'.

摘要： PURPOSE: To eliminate the dispersion in the thickness of an adhesive applied on each wall which divides an ink pressurizing chamber in applying the adhesive on either bonding surface in order to bond a piezoelectric body and a cover body together. CONSTITUTION: A piezoelectric body 2 is arranged under a screen mask 11 so that the transfer direction X1 of the squeegee 13 of a screen printing machine and the longitudinal direction Y of the groove of the piezoelectric body 2 meet at right angles, and an adhesive 8 is applied on the upper surface of each wall 3 in the perpendicular direction X to the longitudinal direction Y of the groove of the piezoelectric body 2 along with the transfer of the squeegee 13.

摘要： PROBLEM TO BE SOLVED: To prevent generation of a leak current in an ink chamber with the result that a portion projecting from an outer edge of an electrode for actuating an ink pressure chamber of an ink jet recording head bursts through an insulation coating on an inner wall of the ink chamber. SOLUTION: A plurality of rows of the electrodes are formed on a face of each piezoelectric. An ink chamber with each electrode in a wall enclosing both sides of a groove by forming the groove by removing the piezoelectric between the plurality of rows of electrodes is formed after the piezoelectrics are superposed with the electrodes arranged oppositely. As to the electrodes, photo-resists of negative type are formed on the piezoelectrics, pattern electrodes are formed via the photo-resists and predetermined outer edges of the pattern electrodes are removed by the laser beam. Also the pattern electrodes may be formed via the photo-resists after forming the photo-resists of positive type on the piezoelectrics.

摘要： PROBLEM TO BE SOLVED: To easily register an ink pressure chamber block and an orifice plate. SOLUTION: A plurality of ink pressure chambers 13 and positioning process parts are formed to an ink pressure chamber block. Orifices 16 and positioning holes 75 and 76 are formed to an orifice plate. The orifice plate is superposed on the ink pressure chamber block. It is judged whether or not a first positioning part set to the positioning holes 75 and 76 and a second positioning part set to the positioning process parts are placed in a set relationship. When the positioning parts are not placed in the set relationship, a position of the orifice plate to the ink pressure chamber block is adjusted. The position of the orifice plate to the ink pressure chamber block can be adjusted by judging whether or not the first and second positioning parts are placed in the set relationship.
