Abstract: The invention relates to an imaging system in which a diffractive optical element is used by both the illumination beam path and the imaging beam path. Said diffractive element operates in the reflection mode or transmission mode according to the specifications of the system design. At least one of the imaging optical elements provided in the beam path of the inventive diffractive beam splitter for imaging systems is used for both the illumination beam path and the imaging beam path. Said element represents a diffractive optical element (DOE) and requires no spatial separation between the imaging beam path and the illumination beam path in the object space by using different diffraction arrays. The number of reflective optical elements can be decreased by using diffractive optical elements, resulting in the cost of the system being reduced and the service life of the optical components being increased by using a low-power EUV source.

Abstract: A mixing head for a reaction injection molding machine includes a body including a mixing chamber formed with an injection bore. In addition to a charging assembly for introducing at least two reactive components into the mixing chamber, there is provided a feed assembly having at least two feeds for supply of different additional components to the mixing chamber. A moveable adapter selectively and detachably couples the feeds of the feed assembly to the injection bore for selective introduction of the additional components. The adapter is constructed for rotation in relation to the mixing chamber so that an exit port of each feed is connectable with the injection bore through rotation of the adapter.

Abstract: A molding apparatus for making molded plastic skins includes a housing shell, and a mold shell which is movably supported on the housing shell for movement thereto and has a wall which is determinative for shaping the contour of a plastic skin. The mold shell and the housing shell define together a hollow space for throughflow of a heat-transfer medium. Flow passageways for heat transfer medium may be provided by subdividing the hollow space between the mold shell and the housing shell by means of partition walls to thereby force the heat-transfer medium to flow along a predetermined path.
