摘要： The invention relates to a computer tomograph provided with a charge-integrating read amplifier having a plurality of gain factors for a data acquisition system as well as a control circuit for the gain factor. In order to avoid noise in addition to the shot noise in computer tomographs of this kind and also to avoid degrading of the DQE (Detection Quantum Efficiency), according to the invention it is proposed that the control circuit automatically selects the gain factor in dependence on the expected integrated input signal of the next frame, the expectation being based on the maximum possible relative variation of the integrated input signal between two successive frames.

摘要： In order to regenerate an activated carbon filter which is seated in a tank vent line, during idling of the internal combustion engine the regeneration valve is brought into the maximum open position, and the throttle valve is simultaneously opened slightly. This produces a higher air mass flow in the intake tract of an internal combustion engine, and the proportion of hydrocarbons introduced by the regeneration remains constant. In order to keep the idling speed of the internal combustion engine constant, a torque reserve is built up, for example by adjusting the ignition angle.

摘要： A valve device for a catheter with a catheter hub. A tubular housing has one end provided with an outer cone for fitting into an inner cone of the catheter hub and has a valve body within acting as a locking member of an axial channel for the passage of an elongate object. The housing is provided with an axially directed protrusion forming a radial space together with the outer surface of the outer cone and has a locking member cooperating with a complementary member at the catheter hub projecting into the space so as to act as a disconnection lock. Thus, a valve device is provided that is suitable for use with a catheter system destined for venous applications according to the Seldinger method, and which ensures a reliable sealing of the extracorporal end of the catheter.
