摘要： A sleeve-like element (14) is arranged inside a hydraulic support element to secure against drainage. In axial direction, the sleeve-like inner element (14) bears a shoulder (13) of a piston (4), formed by a rolled-in step (12). In this manner, the inner element (14) can be secured while the piston (4) maintains a uniform wall thickness.

摘要： A valve actuating lever for a valve drive of an internal combustion engine, includes a main body formed therein with a bore and a shaft received in the bore of the main body and defining a pivot axis about which the main body pivots, to thereby control up and down motions of a gas exchange valve in response to travel of a cam mechanism. The shaft has an outer surface area formed with tangential undercuts oriented transversely to the pivot axis and formed through non-cutting shaping process.

摘要： For picture elements (pixels) having a luminance value in a mid-range of luminance magnitude and a color saturation smaller than a predetermined threshold value a correction signal is obtained by integration of the color saturation value followed by multiplication by the difference between an actual luminance signal and a gradation distorted luminance signal. Threshold values at the boundaries of the mid-range of the luminance signal are determined in a manner dependent upon the extreme values that appear from time to time in the luminance signal. The stored maximum and minimum values of the luminance signals are respectively decremented and incremented at frame intervals until replaced by a new maximum or minimum value establishing a new maximum or minimum.
