摘要： An improved process for synthesizing a sterically unhindered trifunctional primary amine is provided. This process includes the steps of slowly adding a particular unsaturated diester to a solution of a certain diamine in an aromatic organic solvent, and recovering the desired compound. The trifunctional primary amine is useful as a crosslinking agent.

摘要： A method is provided for manufacturing a double hetero-structure of InGaAsP/InP, or, alternatively of InGaAs/InP, for use in lasers and LEDs by means of liquid phase epitaxy. The resulting structures emit optical radiation up to a wavelength of about 1.7 .mu.m. As a result of growing the InP cover layer from an Sn-In-P solution, the meltback of the active layer at gap wavelengths .gtoreq.1.5 .mu.m is avoided, and, thus, no anti-meltback layer is needed. By employing an inverted format for the layer structure with respect to the doping of a starting p-InP substrate, the necessarily highly n-doped InP cover layer has the correct conductivity type. The so-produced double hetero-structures are composed of only three epitaxial layers.

摘要： For use as an emusifier for emulsion polymerization of acrylate monomer mixtures, there is provided a novel mixture of soluble salts of sulfosuccinate half esters of two or three alcohols, each selected from a different class defined and each respective half ester being present in a defined range of proportions in the mixture. The defined emulsifiers, even when used at concentrations less than usual for emulsion polymerization, produce acrylate latex products having a favorable combination of several advantageous properties, particularly good mechanical stability and low viscosity, even when a cross-linking monomer is included in the monomer mixture to be polymerized.

摘要： A generator for producing a low-noise, high-frequency signal has a monomode first laser connected via an optical isolator to a second laser so as to permit light generated by the fist laser to be injected into the second laser. The difference in the frequencies of the lasers and the intensity of the injected light is selected so as to prevent the second laser from locking onto the free-running frequency of the first laser.
