摘要： A piezoelectric actuator, comprising a stacked structure consisting of a top electrode 5, a piezoelectric film 4, and a bottom electrode 3, wherein the piezoelectric film comprises a first group 42 of piezoelectric ceramic particles and a second group 43 of piezoelectric ceramic particles. A distinctive feature is that the particles constituting the first group of piezoelectric ceramic particles are larger than the jingo particles constituting the second group of piezoelectric ceramic particles, and the first group of piezoelectric ceramic particles and the second group of piezoelectric ceramic particles have mutually different compositions. The piezoelectric actuator can thus be manufactured by an application method in a low-temperature environment, and a thicker piezoelectric film can be obtained. In addition, a highly practical piezoelectric film can be provided by combining the advantages of a plurality of material types.

摘要： Disclosed is an ink-jet type recording device that includes drive signal generation circuit 84 for generating a trapezoidal drive signal in synchronization with a timing signal applied from an external device, switching transistors respectively for outputting a drive signal to piezoelectric vibrators in accordance with a printing signal applied from an external device, and control signal generation means for generating a pulse signal to turn on the switching transistors so that only a portion of the drive signal is output to any piezoelectric vibrators set in a non-printing condition in synchronization with a timing signal. This portion of the drive signal is applied to the piezoelectric vibrators belonging to those nozzle openings that should not jet out ink droplets in accordance with the pulse signal, so that menisci in the nozzle openings are merely vibrated slightly, respectively. As a result of this, ink existing in a pressure generation chamber and ink existing in the neighborhood of the nozzle openings are mixed together and thus solvent is supplemented to the ink existing in the neighborhood of the nozzle opening, thereby preventing formation of an ink film due to evaporation of the solvent. Also, even in the non-printing period, the piezoelectric vibrators respectively generate heat to thereby be able to prevent absorption of humidity from the peripheral environment.

摘要： A drop-on-demand ink-jet printing head provided with an array of a plurality of piezoelectric elements arranged at regular intervals and fixed at their one ends to a base, the other ends of the respective piezoelectric elements being free ends which are disposed in opposition to nozzle respective apertures, the piezoelectric elements being formed by cutting, at predetermined width, a piezoelectric plate obtained by firing a lamination of paste-like piezoelectric material conductive material stacked alternately in layers. Since each piezoelectric element is composed of a thin piezoelectric plate interposed between electrodes, if a voltage of only about 30 V, which is sufficient to drive the thin piezoelectric plate, is applied across the electrodes, it is possible to largely flex the whole of the piezoelectric element. By this transformation, ink between the top end of the piezoelectric element and the nozzle aperture is discharged to the outside as an ink drop. Because the driving voltage required for forming an ink drop is as low as possible, it is possible to simplify a driving circuit, and because of cutting a piezoelectric plate, it is possible to form small-sized piezoelectric elements with the same accuracy as in a process of producing a semiconductor.

摘要： A fuel-cell system with a fuel battery comprising more than one fuel cell having a purge gas passage connecting the fuel battery to a purge gas cylinder, a discharge passage connecting the fuel battery to the exterior, solenoid valves each installed in the passages, and an electronic control unit that opens the solenoid valves to open the passages to supply the purge gas to the fuel battery such that residue in the fuel battery is purged to the exterior by the purge gas. The control unit opens the valves at a time interval determined from an output of a current sensor to conduct purge at optimum timing for the battery operating state so as to prevent accumulation of residue in the fuel battery, while preventing repetition of unnecessary purges. Alternatively, manual valves are provided to be manually opened by an operator to open a fuel gas supply passage to supply the fuel gas such that residue is purged by the fuel gas through the discharge passage, thereby enabling fuel supply and purge of residue at starting of power generation, without using an external power source.
