Abstract: A distillation assembly which, with the aid of solar energy, continuously evaporates a feed liquor. The distillation assembly includes a container which contains the feed liquor, a container in which the distillate is collected, these containers being in thermal contact, and a compressor. The compressor compresses the vapor which is produced by boiling the feed liquor using the concentration of solar energy and/or using negative pressure, into the distillate container such that the vapor condenses there, and the evaporation enthalpy and thermal energy is returned to the feed liquor by the thermal contact.

Abstract: The invention relates to an opto-electronic integrated circuit which is optically connected by holograms. An optimum arrangement for as high an integration density as possible of the light sources, detectors, or other opto-electronic components is achieved by light emanating from some of these components of the circuit is reflected back repeatedly and in a point reflected manner onto the circuit by one or more holograms and, selectively and in addition, by optical lenses, with an intensity defined by the hologram, and that the reflected back light impinges partially or totally on components. It is also possible to manufacture a chip which in its interior incorporates a plurality of such structures. On its surface there are provided light sources (2), which radiate light downwardly through the light pervious substrate.

Abstract: An optical vector multiplier can perform linear algebra calculations by using electro-optical modulators of sandwich-type construction or in liquid crystal fields such as occur, inter alia, in the case of neural networks. It can calculate linear algebra operations as rapidly as possible, although the matrix is represented by slow liquid crystal fields. In addition, it can also use the transposed matrix, can calculate the vector product of two vectors and store the resultant matrix of the vector product directly in the region of the matrix modulator cells. To this end, two rapid electro-optical modulators of sandwich-type construction, representing a vector, are disposed offset by 90.degree. and a matrix-shaped optical modulator that represents the matrix follows this arrangement. The vector modulator arrangement that is offset by 90.degree. can form the vector product of two vectors, the result being determined by a detector matrix whose detectors are located on the matrix modulator of each modulator cell.
