A terminal device for a multiplexed data transmission system has a decoder matrix having plural groups of function setting inputs for selecting plural types of functions such as interface, operation modes and other. One group of the function setting inputs are preferably address designating signals which are utilized for determining the interface. The other group of the function setting inputs determines various additional functions such as, for example, enabling/disabling of fail-safe function and automatic transmission function. Selection with the aid of the matrix allows selection of a large number of functions with a small number of input signals. Utilization of the address signals to this end allows the number of terminal pins to be decreased to a minimum.

A slide fastener stringer having a continuous zigzag-shaped thermoplastic molded coupling element strip. The strip includes a succession of spaced coupling elements, each having a pair of first and second legs extending from a head in a common direction, and a plurality of first and second solid connecting portions alternately disposed at opposite sides of the strip and extending one between each adjacent pair of the coupling elements. Each first connecting portion and each second connecting portion extend between an adjacent pair of the first legs and between an adjacent pair of the second legs, respectively. The connecting portions are thin or more slender than the legs. A pair of connector threads extends transversely of the coupling elements through the full length of the strip and they are embedded in the first and second legs, respectively, of each coupling element, each connector thread being disposed close to and extending along a respective one of such two series of the first and second connecting portions.

摘要:
Pulses of electromagnetic energy of appropriate peak power can form soliton pulses in monomode fiber. The width of such pulses changes during propagation, and can decrease for certain ranges of peak power, e.g., between about P.sub.o and 9/4 P.sub.o, where P.sub.o is the "balanced" peak power. Using this property, repeaterless transmission of soliton pulses is possible if the pulses are non-electronically amplified by appropriate amounts at appropriate intervals. Exemplary amplifying means are glass laser, Raman laser, semiconductor laser medium, and cw injection.
