    摘要： An ink jet printing apparatus includes an ink jet head having a plurality of nozzles for respectively ejecting ink drops, a plurality of ink chambers communicating with the nozzles, and a plurality of electromechanical conversion elements corresponding to the respective nozzles. The volume of the ink chamber of the non-drive channel is increased by the influence of the drive channel adjacent thereto, and thereby undesired ejection of the ink drop occurs. To solve this problem, a drive energy set for ejecting the ink drop is applied to the piezoelectric elements of the drive chambers n−1, n+1 and a reduced drive energy set for not ejecting the ink drops is applied to the piezoelectric element of the non-drive channel n.

    摘要： A surface-emission laser array comprises a plurality of surface-emission laser diode elements arranged in the form of a two-dimensional array including a plurality of columns of the surface-emission laser diode elements, each column including therein at least two surface-emission laser diode elements in a first direction. The surface-emission laser diode elements in a column are disposed with an equal interval in the first direction. The plural columns arc disposed in a second direction which is perpendicular to the first direction. An interval between two adjacent columns is larger in a central part than in a peripheral part of the two-dimensional array of the surface-emission laser diode elements in the second direction.
