Abstract: It is the object of the invention to specify a method for the illumination of planes by means of radiation having an approximately Gaussian distribution with respect to its intensity, in which the radiation undergoes periodic deflections relative to the plane to be illuminated in two mutually perpendicular directions, as a result of which the plane to be illuminated is scanned line-wise by the radiation and illuminated as homogeneously as possible. According to the invention, a homogeneous illumination of the plane is achieved when the periodic deviations between the radiation and the plane to be illuminated are at a fixed ratio to one another, and the fraction 1.5 of the standard deviation of the radiation is larger than the spacing between two adjacent write tracks. Application in semiconductor components and integrated circuits (Fig. 1). <IMAGE>

Abstract: An air-cooled internal combustion engine equipped with a hydronamic retarder is combined with a cooling system for the hydronamic retarder fluid. The system comprises a cooling air shroud for directing cooling air past the engine in cooling relationship thereto and a cooling air fan for pushing air through the shroud. The system further includes a retarder oil cooler located upstream from the fan remote from the engine and circuit means are provided for circulating retarder oil through the cooler. Exhaust valves are provided in the shroud and are positioned for diverting at least a portion of the cooling air flow from the shroud when the valves are open. Thus, the overall pressure loss of the system may be decreased and the total flow of cool air through the cooler may correspondingly be increased to increase the cooling efficiency in the cooler.
