    • In order to reduce an unnecessary handover process incident to a sudden change in communication quality, a collection circuit collects information as to the signal quality between a mobile station and respective base stations. A learning circuit learns data for judging handover, based on the signal quality. A determination circuit determines matching between the data for judging the handover and the signal quality collected by the collection circuit. A handover control circuit performs control on handover between the mobile station and a base station brought to a handover additional or deletion candidate of the mobile station, based on the result of determination by the determination circuit.

    • An ink jet print head has nozzles and ink passages each communicating with one of the nozzles. The head includes piezoelectric actuators each for changing one of the passages in volume to eject ink from the associated nozzle. The actuators include leading electrodes extending through the thickness of the body of the head. Because the electrodes are exposed in a surface of the body, an actuator drive IC can be connected directly to the head, and therefore the electrical connections of the head can be simple. A process for making the head body includes the step of laminating green sheets together in which predetermined areas are replaced with materials for forming the leading electrodes of actuators, and the step of sintering the laminate.

    • An ink jet apparatus offers enhanced print quality and is highly conducive to mass-production. The apparatus has a piezoelectric ceramic arrangement including a plurality of ink channels filled with ink. The ink channels are defined by walls and correspond to nozzles. The walls are deformed selectively by a piezoelectric effect to vary the volumes of the selected ink channels to jet out the ink through the corresponding nozzles. The center position of each of the nozzles is allowed to deviate from the middle between one wall of the corresponding ink channel and the other wall opposite thereto by half the distance between the two walls minus half the diameter of the nozzle within the half distance. This arrangement reduces the number of defective ink jet printer heads in the manufacturing phase and allows the ink jet apparatus to offer enhanced print quality. Such an apparatus is also highly conducive to mass-production with no need for specialized adjustments of individual nozzles.
    • 喷墨设备提供了增强的打印质量,并且非常有利于批量生产。 该装置具有包括填充有墨的多个墨水通道的压电陶瓷装置。 油墨通道由壁限定并对应于喷嘴。 壁通过压电效应选择性地变形,以改变所选择的油墨通道的体积,以通过相应的喷嘴喷出油墨。 允许每个喷嘴的中心位置偏离相应油墨通道的一个壁和与其相对的另一个壁之间的中间,两个壁之间的距离减去一半距离内的喷嘴直径的一半。 这种布置减少了在制造阶段中有缺陷的喷墨打印头的数量,并允许喷墨装置提供增强的打印质量。 这种设备也非常有利于批量生产,而不需要专门调整各个喷嘴。

    • A water-repellent film includes a fluorocarbon resin and a surface active agent. The surface acting agent serves as an antistatic agent. The water-repellent films is applied to a nozzle plate substrate by spray coating. Nozzles are then formed by drilling with a laser beam emitted from an excimer laser device. At this time, although the nozzle plate substrate and the antistatic film are processed at the same time, the laser drilling is smoothly performed without any trouble because the antistatic agent of the water-repellant film is a surface active agent. Thereafter, the nozzle plate substrate is attached, via an adhesive, to an actuator member in which ink paths are formed. Since the antistatic agent is mixed in the water-repellent film, the antistatic effect does not deteriorate due to wiping the nozzle surface to remove ink dust and the like from the nozzle surface.
    • 防水膜包括氟碳树脂和表面活性剂。 表面活性剂作为抗静电剂。 通过喷涂将斥水膜施加到喷嘴板基材上。 然后通过用从准分子激光装置发射的激光束钻孔来形成喷嘴。 此时,虽然喷嘴板基板和抗静电膜同时被处理,但由于防水膜的抗静电剂是表面活性剂,所以激光钻孔顺利地进行而没有任何麻烦。 此后,喷嘴板基板经由粘合剂被附着到形成油墨通道的致动器构件。 由于防水剂在防水膜中混合,所以由于擦拭喷嘴表面以从喷嘴表面除去油墨灰尘等,所以抗静电效果不会降低。

    • An ultrasonic motor uses a piezoelectric transducer for effectively transmitting vibration energy and achieving high output. The piezoelectric transducer comprises elastic members, first and second piezoelectric elements, electrodes, and ceramic insulators inserted between the electrodes or between the electrodes and the elastic members. The first and second piezoelectric elements excite the vibration surfaces of the elastic members to vibrate in two modes and to generate approximate elliptical vibration by synthesizing the two vibration modes. The electrodes are provided for applying alternating current signals to the first and the second piezoelectric elements. The first and second piezoelectric elements are polarized such that they cause shear vibration in the same direction. The piezoelectric transducer is fixed in a motor case via a fixing plate.
