    • A communication apparatus which occupies small space and yet can be connected with numerous external cables and which permits a cooling arrangement to be constructed at low cost. An information processing device constituting the communication apparatus has external cable connection ports provided on both top and bottom surfaces thereof, and thus, more external cables can be connected than in the case of connecting the cables to the side surfaces. Also, the external cables connected to the ports are guided along the top and bottom surfaces toward the front of the communication apparatus with their heights restricted by external cable covers and, therefore, do not occupy substantial space above and below the device. Further, since the external cables are connected to the top and bottom surfaces, the front and rear surfaces of the device have spare space, making it possible to construct a ventilation arrangement such as vent holes and fans.
    • 一种通信设备,其占用较小的空间,并且可以与许多外部电缆连接,并且允许以低成本构造冷却装置。 构成通信装置的信息处理装置具有设置在其上表面和底表面上的外部电缆连接端口,因此可以连接更多的外部电缆,而不是将电缆连接到侧面。 此外,连接到端口的外部电缆沿着顶部和底部表面朝向通信设备的前部被引导,其高度由外部电缆盖限制,因此在设备上方和下方不占据实质空间。 此外,由于外部电缆连接到顶表面和底表面,所以装置的前表面和后表面具有备用空间,使得可以构造诸如通气孔和风扇的通风装置。

    • An ultrasonic motor capable of being accurately step-driven comprises a vibrating member piezoelectrically vibrated for driving and halting a movable member. A driving wave is generated for vibrating the vibrating member to drive the movable member, and a halting wave is generated for vibrating the vibrating member to halt the movable member. The driving wave can be either a travelling wave or a standing wave, and the halting wave is a standing wave. The movable member is divided into a plurality of portions, and when the vibrating member is driven by the halting wave, the portions of the movable member become centered at respective nodal portions of the standing halting wave, causing the movable member to stop rotating so that the ultrasonic motor can be accurately step-driven.
