    • A portable drilling machine includes a housing; a drill chuck positioned on a front surface of the housing; a drill bit detachably coupled to the drill chuck; a driver positioned inside the housing to provide either the drill bit or the drill chuck with a rotational driving force; an anti-dust cover having a rear anti-dust cover formed in a cup shape with a drill through-hole formed in a central region of a bottom surface of the rear anti-dust cover and a front anti-dust cover formed in a tube shape to be coupled to the rear anti-dust cover, the front anti-dust cover being adapted to move towards the bottom surface of the rear anti-dust cover when acted on by pressure towards the housing and return to original position when the pressure is removed; and a retainer for detachably coupling the rear anti-dust cover to an outer surface of either the housing or the drill chuck. The rotational motion of the drill bit is not interfered with by the anti-dust cover, and the dust collection space is increased.
    • 便携式钻孔机包括壳体; 位于所述壳体的前表面上的钻夹头; 可拆卸地联接到钻头卡盘的钻头; 位于壳体内部的驱动器,以向钻头或钻头卡盘提供旋转驱动力; 具有形成为杯状的后防尘罩的防尘罩,其具有形成在后防尘罩的底面的中央区域中的钻孔贯通孔和形成在管中的前防尘罩 形状被连接到后防尘罩上,前防尘罩适于当朝向壳体的压力作用时朝向后防尘罩的底表面移动,当压力为 删除 以及用于将后防尘罩可拆卸地连接到外壳或钻夹头的外表面的保持器。 钻头的旋转运动不会受到防尘盖的干扰,并且集尘空间也增加。

    • A floating cell removing device using a generic flow control includes a processor having a generic flow control processing logic for transmitting/receiving a signal cell, checking a generic flow control field of an operation and maintenance cell and removing a floating cell; a pair of cell relay and add/drop function units respectively connected to a subscriber and a network of the processor, for supporting an internal communication between subscriber terminals, temporarily storing the signal cell and transmitting it to a network device; a pair of asynchronous transfer mode hierarchical function processors for converting a cell header, inserting and extracting an operation and maintenance cell, and transmitting it to the processor and the cell relay and add/drop function units; and a plurality of buffers formed between the processor and the cell relay and add/drop function units and between the cell relay and add/drop function units, for temporarily storing data inputted therefrom.
    • 使用通用流量控制的浮动单元去除装置包括具有用于发送/接收信号单元的通用流控制处理逻辑的处理器,检查操作和维护单元的通用流控制字段并移除浮动单元; 分别连接到用户和处理器的网络的一对小区中继和分插功能单元,用于支持用户终端之间的内部通信,临时存储信号小区并将其发送到网络设备; 一对异步传输模式分级功能处理器,用于转换单元头,插入和提取操作和维护单元,并将其发送到处理器和单元继电器和加/放功能单元; 以及在处理器和单元继电器之间形成的多个缓冲器以及加/减功能单元之间以及在单元继电器和加/放功能单元之间,用于临时存储从其输入的数据。
