Abstract:
The invention relates to a plasma generation device comprising a plurality of plasma modules for generating a plasma. Each plasma module has a module housing with at least one gas inlet for supplying a process gas. Furthermore, a discharge device for generating the plasma from the process gas and a plasma outlet are provided. The plasma generation device has at least two plasma modules for generating a plasma. Each plasma module has at least one gas outlet for some of the process gas, wherein the at least one gas outlet of at least one plasma module issues into a respective gas inlet of another plasma module.
Abstract:
A piezoelectric actuator of a multilayer design includes outer electrodes that are fastened by means of a bonding layer applied by thermal spraying. For example, the outer electrodes are formed as a woven wire fabric. Furthermore, a method for fastening an outer electrode in a piezoelectric actuator is specified.
Abstract:
The invention relates to an air-conditioning device for a space to be air-conditioned. The air-conditioning device has a housing including an air supply and an air discharge. In the housing, a flow path is formed between the air supply and the air discharge. In the flow path, at least one heat exchanger, a blower, and a means for generating an excited gas are provided. Furthermore, a surface coating is provided in the flow path, which is configured for the catalytic decomposition of the ozone content of the excited gas, and which is arranged downstream of the means for generating the excited gas.
Abstract:
An apparatus for producing a plasma including a control circuit which is electrically connected to a piezoelectric transformer in order to excite the piezoelectric transformer. A hand-held device that uses the apparatus. The piezoelectric transformer is constructed of several layers. The control circuit is implemented on a circuit board, and the piezoelectric transformer is held over the circuit board by means of a region of a first end. A high voltage is applied to a second free end of the piezoelectric transformer. The plasma is produced at atmospheric pressure.
