Abstract: A reception system for motor vehicles having a diversity antenna system with a plurality of antennas and an antenna switch coupled to a receiver for the reception of digital, MPSK-modulated satellite and terrestrially broadcast radio signals containing phrase reference signals. The antenna diversity system optionally switches through at least one of two available antennas and has a signal level testing device with its input coupled to the receiver and its output coupled to the antenna switch. This is to provide an indication for the need for antenna switching to avoid signal loss by means of a signal at its output, whereby the phase reference signals occur repeatedly in a time sequence.

The first connecting portion includes a pair of coupling portions extending from a base portion and faced to each other and a pair of contacting portions extending from the coupling portions, respectively, and faced to each other. Each of the contacting portions includes a fitting portion coupled to the coupling portion and fitted to the first connection object and a free end extending on a side opposite to the fitting portion. The contact is designed so that, upon connection with the first connection object, a distance between the contacting portions is narrower at the fitting portions than that at the free ends.

Abstract: The invention relates to a lightweight piston comprising heat pipes. The aim of the invention is to simplify the structure of such a piston while at the same time allowing for an improved heat dissipation from the piston areas subject to heat load while avoiding thermal stress. For this purpose, a plurality of liquid-filled heat pipes each having an evaporator and a condenser end is used, whereby the evaporator end is configured by short pipe sections that are oriented in the thickness at bottom towards the focal point and that are interlinked by means of a composite heat pipe extending in parallel to the piston head. At least two pipe sections functioning as the condenser end are coupled with the composite heat pipe in such a manner as to configure, by way of a pipe connection arranged on the condenser ends, a closed coolant cycle between the evaporator end, composite heat pipe and condenser end of the heat pipe.
