    • The invention relates to an electronic ballast comprising a step-up converter for operating a discharge lamp. The electronic ballast is embodied in such a way as to disconnect a switching element (T1) in the step-up converter when a maximum current value of the current flowing through the switching element is reached. The electronic ballast comprises a holding circuit (HS) which is provided with a time-function element (R27, C23) and is embodied in such a way that it sets the time-function element (R27, C23) when the switching element (TI) is disconnected and reconnects the switching element after a time interval defined by the time-function element (R27, C23).

    • A circuit comprising a voltage-controlled transistor (T4), comprising a first (+) and a second (−) supply potential (+,−); a first (Ti) and a second transistor (T2); and an impedance (R4). A series circuit (R4, Ti) is formed by a switching path of the first transistor (T1) and the impedance (R4) is coupled between the first supply potential (+) and a control input of the voltage-controlled transistor (T4). The impedance (R4) is connected in a manner facing the first supply potential (+). The first supply potential (+) is coupled to a control input of the first transistor (T1) via to a switching path of the second transistor (T2). A control input of the second transistor (T2) is coupled to a connecting node (Vi) between the impedance (R4) and the switching path of the first transistor (T1) in such a way that a potential change at the connecting node (VI) can switch the second transistor (T2). The circuit is configured in such a way that as a result of the first transistor (T1) being switched on in a manner mediated by means of a control signal, a first current flows through the series circuit (R4, T1) and starts to subject the control input of the voltage-controlled transistor (T4) to charge reversal in a first sense, the first current through the series circuit (R4, T1) brings about a first potential shift at the connecting node (V1), the second transistor (T2) is switched on by this first potential shift and a second current therefore flows through the switching path of the second transistor (T2) into the control input of the first transistor (T1), which amplifies the first current, the increasing charge reversal of the control input of the voltage-controlled transistor (T4) brings about a second potential shift at the connecting node (VI), the second transistor (T2) is switched off by this second potential shift, and the first transistor (T1) remains switched on, however, and holds the voltage-controlled transistor (T4) in its new switching state.

    • The invention relates to an endoscopic-surgery apparatus for argon-plasma coagulation (APC) to treat biological tissue. The surgery apparatus comprises a tube, a tubular probe or similar working device that can be inserted into an endoscope, with a first channel such that by way of the first channel, as a first working means, there can be guided to the tissue an electrode connected to an HF generator in order to generate a high-frequency current, as well as argon or a similar inert gas. This endoscopic-surgery apparatus is further developed in order to simplify endoscopic interventions employing argon-plasma coagulation, while simultaneously increasing the efficiency of a treatment. To this end, the working device comprises at least one second channel through which at least one second working means is guided to the tissue.
