摘要： In order to enhance the general purposeness of a time domain multiplexer for digital channel signals of unequal bit rates, the time domain multiplexer is constructed of a plurality of channel units which provide information signals and bit rate signals of input channel signals, a plurality of logic circuits which multiplex the information signals from the channel units, and a control circuit which selects and combines the logic circuits in accordance with the bit rate signal so as to construct a multiplexer conforming with the bit rate.

摘要： A two-level alternate mark inversion signal transmission system wherein binary pulses of "1" and "0" levels are converted into a pulse signal in which one coded information value has its polarity inverted at a period T and the other has its polarity reversed at a period T/2, and the converted signal is transmitted. In order to facilitate an automatic gain control operation and the proper and reliable extraction of a timing signal on the receiving side of the system even when the zero binary pulses have successively arisen in the signal processed on the transmitting side, the alternate mark inversion signal is converted into a specified code (zero substitution) signal when the zero binary pulses have succeeded one another for a predetermined number of times, while on the receiving side, a received signal is subjected to duobinary shaping, whereupon the zero substitution part is detected for removal by utilizing the rules of the zero substitution process and the alternate mark inversion signal.
摘要翻译：一种二电平交替标记反转信号传输系统，其中将“1”和“0”电平的二进制脉冲转换为脉冲信号，其中一个编码信息值的极性在周期T被反转，另一个的极性反转为周期T / 2，并且转换的信号被发送。为了便于自动增益控制操作，并且即使当在发送侧处理的信号中连续出现零二进制脉冲时，系统的接收侧的定时信号的适当可靠的提取，交替标记反转信号当零二进制脉冲彼此成功达预定次数时，转换为指定代码（零替换）信号，而在接收侧，对接收信号进行二进制整形，由此检测零替换部分以进行去除通过利用零替换过程和替代标记反转信号的规则。

摘要： In an optical fiber connector, the pair of optical fibers to be connected together are placed end-to-end in a linear groove which has been formed on a lateral surface of a central cylinder. They are held fixed by a holding member which is fitted in the groove and is moved towards the optical fibers according to the rotation of a hollow cylinder which externally touches the central cylinder, whereby the optical fibers can be connected with a precise alignment and accordingly with a low optical power loss.
摘要翻译：在光纤连接器中，要连接在一起的一对光纤被端对端放置在已经形成在中心圆筒的侧面上的直线槽中。它们由固定在槽中的保持构件固定，并且根据外部接触中心圆筒的中空圆柱体的旋转而朝向光纤移动，由此可以将光纤与精确的对准连接，并因此与光功率损耗低。
