Abstract: PURPOSE:To enable a multi-head to be constituted by a simple structure by making positional precision between an electrostrictive vibrator and a cylindrical tube easy by a method wherein a plurality of cylindrical tubes are arranged at positions receiving pressure action of pressure generating parts formed by attaching an electrode to an electrostrictive vibrator or a magnetostrictive vibrator supported with a pedestal. CONSTITUTION:In order to assemble respective components, a number of glassy cylindrical tubes 5a composing a glass cylindrical tube line 5 are arranged in an adjacent state on a solid structured pedestal 10, and end faces on a front face side of respective cylindrical tubes 5a are so arranged as to be located on a same plane. An electrostrictive vibrator 2 is so arranged as to be put above the cylindrical tubes thus arranged uniform, and fixed lest an immoderate load should be applied. A gap among the vibrator 2, respective cylindrical tubes 5a composing the cylindrical tube line 5, and the pedestal 10 is filled by use of fillers being highly hard or the like around an ink chamber 7 so that the ink chamber 7 is hermetically sealed at that time. Since there is thus no necessity for strict registration of the electrostrictive or magnetostrictive vibrator to the cylindrical tube, assembling precision is not strictly requested and a manufacturing cost can be steeply reduced.

Abstract: PURPOSE:To provide an overcharge/overdischarge preventive circuit having balanced capacity. CONSTITUTION:Overcharge detecting comparators COMP2, COMP4 having hysteresis circuits 1 and overdischarge detecting comparators COMP1, COMP3 having hysteresis circuits 2 are connected between positive and negative electrodes of secondary batteries Abat, Bbat connected in series. Transistors T5, T6 and a resistor R are connected between respective batteries for the purpose of overcharge overflow and overdischarge balance. When the COMP2 or COMP4 detects overcharge, a transistor T2 or T4 is turned OFF to interrupt charging current while at the same time a transistor T1 or T3 is turned ON to feed a charging current through a resistor R1 thus sustaining charging operation of battery on the side where overcharge is not detected. When the COMP2 and COMP4 detect overcharge simultaneously, a transistor T10 is turned OFF to interrupt charging current. Hysteresis circuits l, 2 balance overcharge and overdischarge.

Abstract: PURPOSE:To simplify a structure of an ink jet head, multiply the heads, and gather multi-heads by forming an electrostrictive vibrator of ink jet heads into a comb-like shape and arranging the toothed part in an ink chamber so as to be integrated. CONSTITUTION:Each toothed part 2a of a comb-like electrostrictive vibrator 2 of ink jet heads 1 is arranged in a position just under an orifice 5d and a partition wall 5a of an outer frame 5 and the oscillator 2 are fixed by adhesion or compression bonding so as to be integrated. After ink is extruded, ink grains 10 left outside the orifice 5d are extruded in an ejected state and continue flying, for example, in the direction of a recording paper. In an ink chamber 5b, the ink reduces by a volume of the ejected ink grains 10, so that an ink quantity equivalent to the reduced quantity is replenished from an ink supply passage 5e and a state of the ink chamber 5b filled with the ink is restored. Such an operation is repeated in the individual ink chamber 5b of the multiplied head 1, so that desired ink grains 10 can be ejected selectively and continuously.

Abstract: PROBLEM TO BE SOLVED: To realize a sure mixed discharging action by a method wherein the sure formation of a dot having precise density is realized. SOLUTION: At the driving of a printer device having a first pressure chamber, in which a certain amount of a medium is introduced, and a first nozzle communicating with the first pressure chamber, a second pressure chamber, in which a discharging medium is introduced, and a second nozzle communicating with the second pressure chamber, a first pressure applying means for pushing out a certain amount of the medium and a second pressure applying means for discharging the discharging medium, let the first pressure applying means perform a pushing out action from a steady state so as to ooze out a certain amount of the medium from the first nozzle toward the second nozzle in order to bring a certain amount of the medium into contact with the discharging medium near the tip of the second nozzle. After that, let the second pressure applying means perform a discharging action from a steady state so as to discharging a certain amount of the medium and the discharging medium under the state being mixed together. Further, after the end of the pushing out action of the first pressure applying means, the discharging action of the second pressure applying means is brought to an end.
