Abstract: An evaporative light scattering detector (1) has a solvent nebulizer (4) through which an atomised spray of solute solvent solution passes, a heated evaporation chamber (5) and a detector system (6). A diffuser trapping device (7), supported by fine wires, is positioned in the evaporation chamber(5) at about two fifths of the height of the chamber from the top. The diffuser trapping device (7) is made from randomly coiled stainless steel ribbon which gives it a large surface area. The detection system (6) is positioned at the bottom of the evaporation chamber through which a beam of collimated light passes and is scattered by the solvent and detected by a light sensitive device (14). The diffuser trapping device (7) aids evaporation of the solvent and prevents large particles from travelling further down the evaporation chamber (5).

Abstract: A magneto-optical recording apparatus for recording information in a magnetically induced super resolution medium (e.g., magneto-optical disk) comprising a magnetic head having a magnetic core whose sectional area along a plane parallel to a surface of the magnetically induced super resolution medium is larger than 0.08 mm.sup.2, a heating section for heating the recording layer of the magnetically induced super resolution medium, and a recording section for recording the information in the recording layer of the magnetically induced super resolution medium by driving the magnetic head and heating the recording layer using the heating section. Consequently, both the sensitivity to the recording magnetic field and reproductivity of high-density bits of the magnetically induced super resolution medium can be improved.
Abstract: The present invention has an object to eliminate viewing angle dependency in the upward, downward, and right- and left-hand directions, and compensate for optical retardation according to the viewing angle. The liquid crystal display device is provided with at least one optical retardation compensator plate inserted between a liquid crystal display element and polarizer plates. The liquid crystal display element is composed of a pair of electrode substrates and a liquid crystal layer sealed therebetween. The polarizer plates flank the liquid crystal display element. The optical retardation compensator plate has a negative refractive index anisotropy and an inclining refractive index ellipsoid.
Abstract: An image forming system, wherein a second digital copying machine stores image data temporarily on behalf of a first digital copying machine at its request and returns the stored image data upon receipt of a return request. When the second digital copying machine has not received any return request from the first digital copying machine within a predetermined period, the second digital copying machine erases the stored image data to utilize its own memory efficiently.
