摘要： A noncontact transmitting apparatus includes first and second noncontact transmitting units mounted on a main device and an attachment device, respectively. The second noncontact transmitting unit is removably attachable to the first noncontact transmitting unit for enabling noncontact signal transfer between the main device and the attachment device. Each of the noncontact transmitting units includes a power coil and a signal coil. The power coil is wound on a first core to supply power from the main device to the attachment device by electromagnetic induction. The first cores of the first and second noncontact transmitting units face each other at a first position when the attachment device is loaded on the main device. The signal coil is wound on a second core for signal transfer between the main device and the attachment device by electromagnetic induction. The second cores of the first and second noncontact transmitting units face each other at a second position when the attachment device is loaded on the main device. When the attachment device is rotated about the first core by a specified angle, the signal coil of the second noncontact transmitting unit is moved from the second position. This makes it possible for the main device such as a cellular phone, and the attachment device, such as a camera, to transfer power and signals between them with a simple configuration with high reliability when the attachment device is loaded on the main device.

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： 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).

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： 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.
摘要翻译：在喷嘴板上没有改进地控制液滴的粒径。超声波使得在比开口中的液面的基本振动周期短的周期内，对开口间歇地施加放射线压力。然后在开口中的液面处产生高阶驻波，以使多个液滴同时发射。由于多个液滴同时从高阶驻波的多个丘发射，所以液滴的直径小于开口的直径，并且垂直向上发射。液滴的直径由要产生的高阶驻波的顺序控制。通过缩短对开口施加辐射压力的周期来增加驻波的顺序。

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.
