    摘要： The present invention relates to a new polyesterimide of the type containing ester repeat functional groups E=--CO--O--, imide repeat functional groups I: ##STR1## and at least one chromophore, characterized in that it contains a quantity of recurrent amide functional groups capable of ring closure to imides which is smaller than or equal to 5 mol % relative to the sum of the imide functional groups and of the amide functional groups capable of ring closure to imides, which are present, and in that the polymerization functional groups consist essentially of E functional groups. This polyesterimide is preferably free from amide functional groups capable of ring closure to imides. One of the processes for obtaining this polyesterimide constitutes another subject-matter of the invention. Such a polymer is advantageously capable of behaving like a material that is transparent and/or active in nonlinear optics. It therefore constitutes a raw material of choice for producing LO and/or NLO devices: filters, polarizers, waveguides, a modulator, directional coupler, optical flip-flop and photoconductive film.

    摘要： A radio receiver having an FM band tuner, an AM band tuner, a controller coupled to both said tuners, and a radio data (RD) decoder for providing radio data. The RD decoder is coupled for receiving radio data from at least one of the tuners which is tuned to a radio program. The RD decoder is coupled to the controller for switching the radio receiver from FM band to AM band or vice versa based on radio program frequency correspondence data included in the radio data. The radio receiver is advantageous since it allows for automated cross switching between different frequencies whereon a same radio program is broadcast. This is particularly advantageous if the radio receiver, such as placed in a car, leaves the broadcast coverage area. User intervention is thus obviated.
