Abstract: An arc detection means for detecting arcs in a plasma process includes at least one comparator to which an evaluation signal such as an output signal or an internal signal of an AC generator relating to the output signal and a reference value are supplied. The comparator is connected to a logic component that generates a signal for an arc suppression device.

Abstract: A plasma excitation system includes at least one DC current supply connected to a mains supply, at least one medium frequency (MF) unit connected to the at least one DC current supply for generating an AC voltage at its output, and a controller. The output of the MF unit is connected to electrodes of a coating chamber. The controller is connected to the at least one DC current supply for regulating and/or controlling an output value of the DC current supply, and is also connected to the at least one MF unit for regulating and/or controlling an output value of the MF unit. The controller includes at least one input interface for supplying a value describing an output value of the at least one MF unit, and at least one control output interface for connecting a control input of the at least one MF unit.

Abstract: New methods are used for detecting arcs in a plasma process that is fed by, for example, a freely oscillating AC generator with an output signal of the AC generator for supplying power. The method includes measuring or determining a reference value that is based on a time response of the output signal or of an internal signal of the AC generator relating to the output signal. The methods also include comparing the reference value with a threshold value and detecting an arc when a predetermined result of the comparison is obtained.

Abstract: What is proposed is a variator disk for a toroidal variator, in particular for a motor vehicle toroidal transmission. The variator disk has a curved running surface which is oriented coaxially with respect to a variator axis and on which rollers of the toroidal variator can roll. The variator disk having furthermore at least two partial disks which are designed as a traction disk, on which the running surface is formed, and as a supporting disk, respectively. The supporting disk is designed for supporting axial forces applied to the running surface. The traction disk is supported on the supporting disk in the radial direction to the variator axis.

Abstract: A method for regulating and/or controlling an engine-transmission unit in a motor vehicle includes prioritizing torque demands to obtain an only torque value, storing the only torque value as a current successful situation and retaining the torque value for the previous successful situation, and processing the torque value of the current successful situation as well as the torque value of the previous successful situation to comparable torque values in each case required for the implementation of the demands.
