    • A buckle has a cover rotatably connected to an end of one of bands, a middle plate rotatably connected to the cover, and a bottom plate rotatably connected to the middle plate and rotatably connected to the other band. A guide housing is secured to an underside of the cover, and a pair of push plates are slidably mounted in the guide housing. A spring is provided between the push plates for outwardly urging the push plates respectively. A slant is formed on an engaging projection of the push plate. A pair of lugs are formed on the bottom plate. Each of the lugs has an engaging hole and is arranged such that the lug is engaged with the slant so as to inwardly move the push plate, and that the engaging hole engages with engaging projection of the push plate, thereby coupling the buckle. A leaf spring is provided for urging the cover in a disengaging direction.
    • 带扣具有可旋转地连接到一个带的端部的盖,可旋转地连接到盖的中间板和可旋转地连接到中间板并且可旋转地连接到另一个带的底板。 引导壳体固定在盖的下侧,一对推板可滑动地安装在引导壳体中。 在推板之间设置弹簧,用于分别向外推动推板。 在推板的接合突起上形成倾斜。 在底板上形成一对凸耳。 每个凸耳具有接合孔,并且布置成使得凸耳与倾斜部接合以便向内移动推板,并且接合孔与推板的接合突起接合,从而联接带扣。 提供了用于在分离方向上推动盖的板簧。

    • An X.25 protocol apparatus can communicate with another X.25 apparatus or a X.32 apparatus through a telephone network, an ISDN network, or a PBX network, by attaching protocol conversion system to the X.25 apparatus. The conversion system has a pair of signal identification portions (1, 6) for separating a receive packet to a data packet and a control packet, a call process portion (3, 12) for dial signal process, and an address table (4) and a packet edition portion (5) for address conversion of a control packet. A data packet is forwarded from one signal identification portion to another signal identification portion through direct path (53). A control packet is forwarded to a control packet identification portion (2) for control process which includes dial signal process, address conversion, and protocol sequences. This system is applicable to couple a data communication network which has a X.32 correspondence portion to another data communication network.
    • 通过将协议转换系统附加到X.25装置,X.25协议装置可以通过电话网,ISDN网络或PBX网络与另一X.25装置或X.32装置进行通信。 转换系统具有用于将接收分组分离成数据分组和控制分组的一对信号识别部分(1,6),用于拨号信号处理的呼叫处理部分(3,12)和地址表(4) 以及用于控制分组的地址转换的分组编辑部分(5)。 数据分组通过直接路径(53)从一个信号识别部分转发到另一个信号识别部分。 控制分组被转发到控制分组识别部分(2),用于控制过程,其包括拨号信号处理,地址转换和协议序列。 该系统适用于将具有X.32对应部分的数据通信网络耦合到另一数据通信网络。
