摘要:
O,S-dialkyl S-[carbamyloxyalkyl] dithiophosphates of the general formula (I) ##STR1## where, independently of one another, R.sup.1 and R.sup.2 are each alkyl of not more than 4 carbon atoms and R.sup.3, R.sup.4 and R.sup.5 are each hydrogen or alkyl of not more than 6 carbon atoms, or R.sup.4 and R.sup.5, together with the nitrogen atom to which they are bonded, form a saturated or olefinically unsaturated ring which contains not more than 6 carbon atoms and may or may not contain one or more oxygen, sulfur or nitrogen atoms, are used for controlling insects or mites.
摘要:
A method for the manufacture of optical components, at least one three-dimensional optical waveguide structure being produced in a light-sensitive substrate by locally subjecting the substrate to an exposure so that a difference in refractive index between the substrate and the at least one optical waveguide structure is created. Provision is made for an exposure to occur at least twice, at different angles of incidence for the light perpendicular to a light wave propagation direction of the optical waveguide structure; the substrate surrounding what will later be the optical waveguide structure thereby experiences a diminution in refractive index, the optical waveguide structure being defined using a mask.
