    摘要： Novel substituted polyamides of the general formula ##EQU1## wherein A and B, which may be identical or different, are the hydrocarbon backbone groups of the formula --(CH.sub.2).sub.n --, where n is an integer, R.sub.2 and R.sub.3 are the residues of an aldehyde R.sub.2 --CHO or of an isocyanide R.sub.3 --N.tbd.C, where R.sub.2 and R.sub.3 are aliphatic, aromatic or heterocyclic residues of the respective aldehyde or isocyanide, or where R.sub.3 is a chromophoric moiety. R.sub.2 and R.sub.3 can be substituted, and amongst the possible substituents there may be R.sub.3 designating --(CH.sub.2).sub.n --NHCO--CHR.sub.2 --N(CO)(R.sub.4)--X, where R.sub.4 is the residue of a monocarboxylic or dicarboxylic acid and X is the lysyl residue of a protein, which may be biologically active, or the residue of a low-molecular weight compound containing a primary amine moiety. Preferred polyamides are various types of nylons. Amongst proteins chemically bound to the polyamide there may be mentioned enzymes, antibodies and peptide hormones. When R.sub.3 is a chromophoric moiety, the product is a chemically dyed polyamide. The invention relates also to a process for the production of such novel substituted polyamides.

    摘要： The invention relates to a semi-conductor optical amplifier insensitive to the polarization of light. The active layer (20) of this amplifier is made up of an alternating series of solid sub-layers alternately under tensile stress (21) and compressive stress (22) and having the same forbidden band-width. The sub-layers under tensile stress (21) favour the propagation of the TM mode of polarization of light and the sub-layers under compression (22) favour the propagation of the TE mode of polarization of light. In addition, the thicknesses of the sub-layers have values which ensure equal gains G(TE) and G(TM) for the active layer.

    摘要： Primary molecules are formed by sublimation in a sublimation chamber (2), they are then transferred at a transfer flow-rate to a decomposition head (10) at a higher temperature, and they are transformed therein into secondary molecules that are lighter in weight to form molecular beams (16). In accordance with the invention, the transfer flow-rate is adjusted by adjusting an effective vector flow-rate which is the vector flow-rate of a vector gas inserted into the sublimation chamber via a feed tube (26) and sucked out via a suction tube (30). The invention applies, in particular, to making III-V type semiconductor components by molecular beam epitaxy.

    摘要： A vacuum evaporation device incorporates a main treatment enclosure connected to an auxiliary chamber containing a material evaporation cell. The cell is fixed to a tight bellows displacement member able to displace the cell between a first advanced position towards a main enclosure and a second retracted position. A sealing valve provided with a slide is provided for the main enclosure from the auxiliary chamber, whereby the material of the evaporation cell can thus be changed without placing the main enclosure under atmosphere again. A fixed heating tube, connecting the main enclosure to the auxiliary chamber, has a first end engaged in the main enclosure and a second end issuing into the auxiliary chamber. The second end is provided with an end piece made from a thermally insulating material ensuring mechanical continuity and thermal insulation with the support part and able to bearingly receive the evaporation cell when the latter is in the advanced position. The slide of the sealing valve is inserted between the end piece and the evaporation cell when the latter is in the retracted position, the travel of the cell between these end positions and consequently travel of the bellows being limited to the space necessary for closing the valve.

    摘要： A common corrective eyeglass lens blank and a common mirror, Plano or magnifying, are brought together in a “compact” (small sized) construction and assembly to provide the very thing long desired in mirrors and not elsewhere found—corrected vision and ample working room between the eyes and any lenses, at the same time, at reasonable cost, in an elegance of implementation.

    摘要： From a top face of a semiconductor structure of the III-V type, inter-diffusion of elements between the wells and the barriers of an internal quantum structure is hot induced. The inter-diffusion is performed in one segment of the structure only, namely a segment in which the characteristic wavelength is to be shifted so as to constitute an amplitude modulator, another segment of the structure including a Bragg grating so as to constitute a laser emitter. In accordance with the invention, the inter-diffusion is induced by a layer of indium maintained in contact with the top face by means of a dielectric encapsulation layer. The invention is applicable in particular to optical telecommunications.
