摘要:
The invention relates to novel ionic compounds which can be incorporated in polymers whose monomer units include at least one hetroatom, particularly oxygen or nitrogen adapted to form bonds of the donor-acceptor type with the cation of the ionic compound, the solid solutions obtained being utilizable to form the electrolyte of an electrochemical generator. These ionic compounds are represented by the formula(C.sub.n X.sub.2n+1 Y).sub.2 N.sup.-,M.sup.+in which : X is a halogen, n varies from 1 to 4, Y is a CO or SO.sub.2 group and M is an alkali metal.
摘要:
There is provided a combined variable resistor assembly provided with position indicator means for indicating positions of individual variable resistors by respective bright spots adapted to be moved by manipulating the associated variable resistors. This variable resistor assembly may find use mainly for electronic tuners, and with which the present states of the individual variable resistors for volume control, balance control, sound quality control and so forth can be known at a glance at the indicator means.
