摘要： A liquid-drop ejection device having a plurality of ejectors each having a variable-capacity ink channel. The capacity of the ink channels is variable to generate sufficient pressure to thereby eject ink in the ink channels from nozzles communicating with the ink channels onto paper or the like. The ejection device further comprises a piezoelectric transducer having a plurality of walls for separating the ink channels from one another. The walls have drive electrodes formed on upper or lower portions. The upper portions of the walls are narrower in width than the lower portions. A method of forming the ejection device comprises a first step of forming grooves including portions for receiving drive electrodes, a second step of forming the drive electrodes in the grooves and a third step of further forming the grooves to provide additional portions having widths different from the portions of the grooves formed in the first step.

摘要： An array of ink droplet ejection devices for use in a drop-on-demand type printer includes a piezoelectric transducer and a cover plate. Both the piezoelectric transducer and the cover plate are formed with a plurality of grooves in parallel to one another. The groove-formed surfaces of the piezoelectric transducer and the cover plate are engaged with each other to form a plurality of ink channels. The piezoelectric transducer and the cover plate are in surface contact with each other at the side surfaces of the respective protrusions. The protrusion of the piezoelectric transducer is uni-directionally deformable to be substantially out of surface contact with the protrusion of the cover plate. With such a construction, the individual ink channels can be operated independently of one another and ink droplets can be simultaneously ejected from the adjacent ejection devices.

摘要： A droplet ejecting device comprises a piezoelectric transducer consisting of first and second piezoelectric transducers polarized in the directions opposite to each other, the first and second piezoelectric transducers bonded to each other and having electrodes disposed at the inner and outer surfaces thereof. A member is fitted to the piezoelectric transducer to define ink chambers, the member having an orifice associated with each ink chamber. An injection controller applies an electric field to the electrode(s) associated with the predetermined ink chamber(s) so as to eject an ink droplet(s) from the ink chamber(s) through the orifice(s) in a given position. As a result, the invention provides a droplet ejecting device where an ink ejecting cycle of the array as a whole is short, the print speed is high, and electrodes can be easily manufactured.

摘要： An ink droplet jet device in which the volume of the ink channels is varied by deformation of the side walls due to piezoelectric thickness shear mode to thereby jet an ink droplet requires sufficient volume variation of the ink channels to function reliably. To satisfy this requirement, the material and thickness of an adhesive agent used to secure the piezoelectric plate to the cover plate is selected so that the value obtained by dividing Young's modulus of adhesive agent for adherence between the upper surface of the side wall of the piezoelectric plate and the cover plate by the thickness of the adhesive agent is above 5.times.10.sup.3 kg/mm.sup.3, preferably 5.times.10.sup.4 kg/mm.sup.3, and more preferably above 1.2.times.10.sup.5 kg/mm.sup.3. Further, the material and thickness of the adhesive agent is selected so that the value obtained by dividing Young's modulus of the adhesive agent for adherence between the end surface of the side wall and the nozzle plate by the thickness of the adhesive agent is below 1.times.10.sup.6 kg/mm.sup.3, preferably 5.times.10.sup.5 kg/mm.sup.3, and more preferably 3.times.10.sup.5 kg/mm.sup.3. By these settings, the jet velocity of the ink droplet is above a predetermined value, and stable ink droplet jetting can be performed.

摘要： A sewing machine having separate drives for the needle bar and looper includes initialization routines to place the needle bar and looper in predetermined starting positions prior to the start of a sewing operation. Position detectors comprise photoelectric cells and interrupters mounted on the motor shafts of the needle bar drive motor and the looper drive motor. The position of the needle bar is initialized first, by movement in a reverse direction, if necessary, to prevent undesired engagement with the looper. Thereafter, the looper position is initialized. A sewing operation is enabled once the needle bar and looper are set in predetermined starting position.

摘要： A data converting apparatus for converting outline data including multiple sets of segment data representative of respective segments of an outline of a character, into dot data representative of the character. The data conversion is effected according to a conversion rule that each stroke of the character is constituted by picture elements which lie within an outline of the stroke so as to satisfy a predetermined requirement, when the character outline is superimposed on a coordinated pixel screen wherein the picture elements are defined by parallel x-axis and y-axis lines. The apparatus includes an ornamental end data converter operable without following the conversion rule, for processing ornamental end data comprising at least one of the multiple sets of segment data of the outline data which represents an ornamental end portion of an ornamented stroke of the character. The ornamental end data converter converts the ornamental end data into a predetermined block of dot data associated with the ornamental end portion of the ornamented stroke.
