摘要： The particle diameter of droplets is controlled without improvements on a nozzle plate. An ultrasonic wave causes a radiation pressure to be intermittently applied to an opening in a cycle having a period shorter than the fundamental vibration period of a liquid surface in the opening. A high-order standing wave is then generated at the liquid surface in the opening to cause a plurality of droplets to be emitted simultaneously. Since the plurality of droplets are simultaneously emitted from a plurality of mounds of the high-order standing wave, the droplets have a diameter smaller than the diameter of the opening and are emitted vertically upwardly. The diameter of the droplets is controlled by the order of the high-order standing wave to be generated. The order of the standing wave is increased by shortening the period for which the radiation pressure is applied to the opening.

摘要： A liquid ejector increases the density of acoustic energy to eject droplets efficiently. Acoustic waves are introduced in generally planar form from a piezoelectric transducer into a liquid ink in a reservoir and are reflected from a reflecting wall of the reservoir. The reflecting wall defines a parabola in cross section. An ejection opening is located near a focal point of the parabola, opposite the transducer. The acoustic waves focus at the ejection opening, increasing the density of the acoustic energy in the ink at the ejection opening. Thus, ink droplets are ejected efficiently from the ejection opening.

摘要： A nozzle hole of a conductive nozzle plate exposes the liquid surface of conductive ink. Ultrasonic generation means vibrates the ink for forming fine surface waves on the liquid surface so that the ink is sprayed from the nozzle hole as an atomized liquid particle group. A back plate provided on the opposite side of the nozzle hole in relation to a printing paper is supplied with a potential different from that for the nozzle plate, so that an electric field is formed therebetween. The sprayed liquid particle group is charged and hence urged by this electric field to adhere to the printing paper.

摘要： A reflector has an inlet opening toward a piezoelectric element, an outlet opening toward a nozzle plate and a reflecting wall connecting the same with each other. The nozzle plate has a nozzle located in the vicinity of the outlet. The piezoelectric element is provided with a through hole on a position opposed to the outlet, and applies ultrasonic waves to a liquid supplied into the reflector from the through hole. The ultrasonic waves are reflected by the reflecting wall and converged in the vicinity of the outlet for improving acoustic energy on this position so that the nozzle ejects droplets. Thus, the dimension in a direction perpendicular to that for ejecting the droplets is suppressed for providing a droplet ejector having a compact structure.

摘要： At a dot cycle (T3), a dummy burst signal as well as a jet burst signal are supplied for a vibration exciter to drive it so that the vibration exciter can provide liquid with a periodic radiation pressure. The dummy burst signal is so determined as to jet no droplet, with a smaller number of pulses and so on. That allows a stable motion of meniscus of ink and it is thereby possible to stably jet the droplets. With this control provided is a technique to improve a shape of an ink surface from which the droplets are created and stably jet the droplets when a liquid jet unit for jetting the droplets from a liquid surface is driven.

摘要： A longitudinal wave propagates in ink toward an opening. The surface of the ink is positioned at the opening and is curved. A surface wave is excited from an end of the liquid surface owing to a restoring force caused by surface tension of the ink. Assuming that the wavelength of the surface wave is &lgr;c, the diameter of the opening is established to be not smaller than 2m &lgr;c. The surface wave is generated from an edge of the opening and rapidly decreases due to the longitudinal wave. The surface waves caused by the longitudinal wave do not interfere with each other at the opening provided that certain conditions are established. Therefore, no complicated interference wave occurs on the surface of the ink, and the surface of the ink vibrates with a large amplitude in the vicinity of the edge of the opening.
摘要翻译： 纵向波在墨水中向开口传播。 墨水的表面位于开口处并弯曲。 由于由油墨的表面张力引起的恢复力，表面波从液面的端部被激发。 假设表面波的波长是lambdc，则开口的直径被确定为不小于2m lambdc。 表面波从开口的边缘产生，并且由于纵波而迅速减小。 如果建立某些条件，则由纵波引起的表面波在开口处不会相互干扰。 因此，在墨的表面上不会发生复杂的干涉波，并且墨的表面在开口边缘附近以大幅度振动。

摘要： A nozzle ejects molten metal in an ejecting direction. The nozzle has a solder-philic surface in a first region and a solder-repellent surface in a second region. The second region is located forward of the first region in the ejecting direction. Before molten metal is ejected, the peripheral edge of the liquid surface of the molten metal is held at a position located further forward in the ejecting direction than the boundary between the solder-philic surface and the solder-repellent surface. The peripheral edge of the liquid surface is thus held before being ejected so that solder drops can be ejected steadily with a uniform diameter, constant direction, and constant speed.

摘要： A reflection surface (1a) of a mirror (1) has a rotationally-symmetrical shape about an optical axis (110). The mirror (1) is rotatably supported by a pivot supporting portion (41) on the position of the optical axis (110) of the reflection surface (1a) or in the vicinity of the optical axis (110). Furthermore, the mirror (1) is slidably supported by slide supporting portions (42) at two positions on the upper part thereof. With such a configuration, the mirror (1) is supported at three points. Further, even when the mirror (1) expands and contracts due to the change in temperature or the like, the deformation of the reflection surface (1a) of the mirror (1) is prevented by the action of the slide supporting portions (42). As a result, it is possible to prevent the generation of distortion of an image projected on a screen (300).
