    Abstract: In a phase-locked loop comprising a phase detector (1), a loop filter (5) and a controlled oscillator (17) which are arranged on a common integrated circuit, interferences coupled into the substrate of the integrated circuit by other parts of the circuit are suppressed. In a first embodiment of the invention, this object is achieved in that the controlled oscillator (17) is preceded by a capacitive voltage divider (9) which comprises at least two capacitances (10, 12), the controlled oscillator (17) is controlled in dependence upon the output signal of the capacitive voltage divider (9), and the capacitive voltage divider (9), together with the phase detector (1), the loop filter (5) and the controlled oscillator (17) is arranged on an integrated circuit. In accordance with a second embodiment of the invention, the reduction of interference is achieved in that the controlled oscillator (17) has a differential structure and comprises at least two voltage-controlled current sources (18, 19) whose circuits are coupled to a power supply potential and to a substrate on which the integrated circuit is arranged, the controlled oscillator (17) has an output stage (20) which is arranged behind the voltage-controlled current sources (18, 19) and generates two differential digital signals in dependence upon the differential signals applied thereto, which differential digital signals are generated with a high edge steepness by means of switching between two potentials and are applied to amplifier stages (56, 57) which are arranged between power supply potential and reference potential and supply two differential output signals operating at reference potential.

    Abstract: Electrode and specifically a transparent electrode for an electrolytic cell and specifically an electrolytic display cell constituted by a transparent conducting layer having a configuration suitable for display purposes and deposited on an electrically insulating transparent support. The transparent conducting layer is coated with a thin transparent conducting film made from a material different from that of the conducting layer, so that under the operating conditions of the cell it is possible to limit the overvoltage on the electrode to such a value that there can be no secondary reactions liable to bring about a transformation of the materials forming said layer and said film. The layer is made from tin-doped indium oxide and the film from tin oxide doped with antimony or cadmium.

    Abstract: The turbomachine has a ring of radial blades which are connected to an annular end wall. Situated on the end wall upstream of each blade is a deflector wedge with two divergent guide surfaces. The deflector wedge generates pressure-side and suction-side vortices of which the vortices caused by the blade cascade are altered such that the transverse flow and backflow areas on the blade are reduced, and therefore the edge zone losses are decreased.
