A lamp holder that can receive a discharge lamp has an insulating body that can work with an electrically conductive junction box. An instruction dispatch circuit, coupled to the first instruction storing circuit dispatches L instructions stored in the first instruction storing circuit, wherein L is less than or equal to N. a structure formed by successive amphiphilic, lipophilic or inert matrices and finally inglobated or dispersed in hydrophilic matrices. Sensitive gas sensors can thus be placed at cooler positions of the exhaust-gas system that are less exposed to vibration and can nevertheless determine the pollutant concentration at another position. Moreover, this class of fire suppressant compounds hydrolyze or oxidize rapidly in the troposphere and as a consequence thereof, they have minimal ozone depletion potential. When the magnetic rotor is turned by the magnetic induction of the coil stators, the fixed solenoid turns in the inner solenoid base, and the inner solenoid base is limited by the limiting unit.
