  • Patent number: 9073308
    Abstract: The piezoelectric element includes first and second sheets 30 and 40 that are stacked and burned. In this stacked state, a second electrode 60 is located on a first long side 30a having a first non-electrode region 51. Thus, before a conductive film 100A is formed, the end face of a first electrode 50 and the end face of the second electrode 60 are exposed on lateral surfaces 20b and 20d on the same side and can be observed thereon. Slits 91 are formed at certain intervals in a lengthwise direction X. The conductive film 100A is formed so as to apply a voltage between the second electrode 60 exposed on a front surface 20a and ends 20ab and 20ad, thereby driving the piezoelectric element only with connection from the front surface 20a.

  • Patent number: 8979248
    Abstract: A plurality of ink-jet heads are displaced over time on a line scan head loaded with the ink-jet heads, leading to lower printing accuracy. A plurality of uneven portions are formed in parallel with a print-scan direction on the faying surfaces of the ink-jet heads and a head plate loaded with the ink-jet heads, allowing a displacement made over time after positioning to be guided in the print-scan direction. This can suppress a displacement in a direction orthogonal to the print-scan direction, achieving an ink-jet apparatus that can keep high printing accuracy using this solution.

  • Patent number: 7633464
    Abstract: Driving a plasma display panel, in which generation of a region having brightness non-uniformity can be reduced over an entire screen without changing the voltage and pulse width of sustain pulses, to enable suppression of an increase in power consumption. This driving of the plasma display panel comprises (i) an initialization period for forming a discharge cell at an intersection where a scan electrode and a sustain electrode meet a data electrode and generating initialization discharge in the cell, (ii) a writing period for generating writing discharge in the discharge cell, and (iii) a sustain period for generating sustain discharge by alternately applying sustain pulses to the scan electrode and sustain electrode of the discharge cell. The rise time of the sustain pulses applied to the scan electrode and sustain electrode during the sustain period is shortened at a frequency of once every several times.
