摘要： Characteristics of a droplet ejection apparatus are change depending on the shape or cone angle of the main ink ejection chamber of the apparatus, or on the diameter of the ejection aperture of main ink ejection chamber. Accordingly, operation of the droplet ejection apparatus varies with the shape, angle, or diameter of main ink ejection chamber. The shape of the aperture according to the present invention is circular or regular polygonal so that surface waves are synthesized at the central portion of the ejection aperture. Moreover, the cone angle of the main chamber is set to 65° or less from the plane vertical to the droplet ejecting direction and the diameter of the ejection aperture is set to a value 1.25 times or more larger than a desired droplet diameter.

摘要： In an ink jet head, in order to make the occupying area of a chamber associated to each nozzle as small as possible, while maintaining a discharge ink drop volume, and on the other hand, to locate a number of nozzles with a high density, the plan view shape of a pressure plate provided to each chamber is so configured to fulfill the relation of 1:≦A≦2, where “A” is the ratio of an circumscribed circle diameter of the plan view shape of the pressure plate to an inscribed circle diameter of the plan view shape of the pressure plate. For example, the pressure plate is formed to have the plan view shape of a substantial square or a substantial rhombus. The chambers having such a feature are located in the form of a matrix. Thus, a stably driven, highly reliable ink jet head can be realized.

摘要： Disclosed herein is a piezoelectric actuator comprising a plurality of driving columns separated by grooves in which the width of each driving column in the direction of the groove width widens from the displacement output surface to the substrate. The widening of the diving column width toward the substrate realizes a piezoelectric actuator having a high strength and a high reliability capable of stably and effectively generating an output displacement.

摘要： A pressurizing unit for pressurizing ink filling a pressure chamber in response to an electric signal is constructed with a beam and a support portion. The support portion is preferably formed integrally with the beam and supports the beam at opposite end portions thereof. The support portion receives a bending force and a shearing force, with are generated at the opposite end portions by a buckling deformation of the beam when the beam is expanded in its longitudinal direction by an application of the electric signal.
