摘要： A circuit arrangement for current supply in processes of electrochemically initiated plasma-chemical layer production. It is preferably applied in the plasma-chemical conversion of electrochemically pre-formed layers, e.g. on light metals. The output of the adjustable three-phase transformer with subsequently connected 6-pulse rectifier circuit is branched twice, wherein a first bridge circuit comprises a capacitor connected in parallel to a voltage sensor. A second bridge circuit contains a freewheeling diode parallel to the current limiting choke and the bath for process implementation. A pulse analyzer is arranged parallel to the latter, and the two bridge circuits are separated by a switch element. An optoelectronic sensor which is connected with the control unit, as is the pulse analyzer, the voltage sensor and a current sensor, is introduced for indicating the pulsed plasma discharges controlled by the circuit arrangement, wherein the control unit influences the switch element with the three-phase transformer in a directed manner to optimally adjust the pulse frequency and duty factor.

摘要： A device is described for generating operating states characterized by dirences in height in actuators arranged in a matrix. In order to enable operating states which are characterized by differences in height to be produced in mechanical actuators in close matrix-type arrangement which are controllable selectively and independently from one another in a simple manner in a suitable device a reservoir filled with electroviscous liquid has an over-pressure chamber and a negative-pressure chamber and these chambers are connected via separate control ducts with hydraulic cylinders of the actuators, the connection to the two chambers of the reservoir being opened or blocked alternatively by the two control ducts of an actuator via a first electrode and a second electrode and a controllable center electrode common to both. The pressure variation formed in this way changes the vertical adjustment of a mechanical pin via an elastomer diaphragm. The device is used primarily for adaptive circuit board testers and for representing braille text.
