A wiping device has a wiping section that relatively moves along the nozzle surface, and the wiping section has: a curved surface in which a bulge is continuously formed along the identification line; a guiding section disposed such that the bulge faces the nozzle surface; a gas jetting port that applies gas to the curved surface; and a gas suction port that sucks the gas ejected from the gas jetting port and guided along the curved surface, wherein, as viewed from the direction perpendicular to the nozzle surface, the identification line which is the set of upper end points on the bulge on the curved surface intersects with the edges of the nozzle surface at an oblique angle.

Wiping device, ink-jet device, and wiping method

The piezoelectric element includes first and second sheetsandthat are stacked and burned. In this stacked state, a second electrodeis located on a first long sidehaving a first non-electrode region. Thus, before a conductive filmA is formed, the end face of a first electrodeand the end face of the second electrodeare exposed on lateral surfacesandon the same side and can be observed thereon. Slitsare formed at certain intervals in a lengthwise direction X. The conductive filmA is formed so as to apply a voltage between the second electrodeexposed on a front surfaceand endsand, thereby driving the piezoelectric element only with connection from the front surface

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.

Ink-jet apparatus

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.
