摘要： A cooling arrangement with a housing for receiving electronic printed circuit boards or plug-in modules, and with an air-conditioning device which is connected via a coolant-conducting feed line and a return-flow line with at least one electronic component, to be cooled, on the respective printed circuit board or the plug-in module. The feed line is coupled with at least one component feed line assigned to the electronic component. The return-flow line is coupled with at least one component return-flow line assigned to the electronic component. The printed circuit board or the plug-in module has an area for fitting electronic components and a coupling area for coupling the feed line with the component feed line and for coupling the return-flow line with the component return-flow line.

摘要： A multi-layer circuit board which includes at least two boards carrying conductors and a shielding foil interposed between the two boards. The circuit board is provided with a through hole including a metallic lining in electrical connection with the shielding foil. The lining includes an insulating layer on which a conductive metal layer is disposed. The metal layer, electrically separated from the lining by the insulating layer, is in electrical connection at respective ends thereof with the conductors. By virtue of this arrangement a coaxial design of a through hole results thereby permitting a total decoupling with respect to adjacent or neighboring through hole connections.

摘要： An electronic musical instrument comprises a sound generator connected to a loudspeaker by way of several parallel channels including respective delay lines constituted by charge-transfer devices of the bucket-brigade type stepped by different high-frequency pulse generators. Each pulse generator comprises a voltage-controlled oscillator whose output frequency is varied by a composite periodic signal obtained from a respective stage of a chain of operational amplifiers each provided, except possibly for the first stage, with an RC network acting as a frequency-dependent phase shifter for a nonsinusoidal modulating signal consisting of at least two sub-audio-frequency components. The modulating signal may be synthesized from a plurality of stepped waveforms generated by the concurrent readout, at different sampling rates, of a set of amplitude values stored in a read-only memory.
