摘要： A circuit arrangement for igniting and operating a discharge lamp (La), provided withinput terminals (K1,K2) for connection to a DC voltage source,a commutator (COM) coupled to the input terminals and provided with terminals (K3,K4) for connecting the discharge lamp (La), for cornmutating a current through the discharge lamp (La),a branch A which is conducting in both directions at least for alternating current, of which branch a first end is connected to an input terminal (K2) and a further end is connected to the commutator (COM), and which branch comprises an inductive element L shunted by a branch B which comprises a unidirectional element (D),a branch C which connects a further input terminal to the commutator (COM), andan ignition circuit (S) for igniting the discharge lamp. According to the invention, the unidirectional element (D)is so included in the branch B that the branch B conducts a current at least immediately after ignition of the discharge lamp (La). It is achieved thereby that a lamp operated by means of the circuit arrangement has good take-over properties.The invention relates to a circuit arrangement for igniting and operating a discharge lamp, provided withinput terminal for connection to a DC voltage source,a commutator coupled to the input terminals and provided with terminals for connecting the discharge lamp, for commutating a current through the discharge lamp,a branch A which is conducting in both directions at least for alternating current, of which branch a first end is connected to an input terminal and a further end is connected to the commutator, and which branch comprises an inductive element L shunted by a branch B which comprises a unidirectional element,a branch C which connects a further input terminal to the commutator, andan ignition circuit for igniting the discharge lamp.

摘要： An integrated circuit having logic circuits and a logic output buffer, which circuit includes the following sub-circuits: a memory circuit and a logic output circuit, in which no tri-state occurs at the output during a sequence of data signals at the input, wherein the drive of the circuit by means of control signals is not critical over time because the first data signal from the sequence switches off the tri-state mode, the tri-state mode again being introduced if a control signal is furnished, and in the absence of this control signal, the last data signal is retained.

摘要： The electric lamp has a vacuumtight seal (4) on the longitudinal axis (2) of a glass lamp vessel (1). An internal (12) and an external conductor (13) each have an end (14) inside the seal (4) and extend through a common axial region (5) of the seal (4) in a spaced apart manner. Several metal foils (11) arranged in a flat plane of the seal (4) extend parallel one to the other, in a transversal direction thereof. They have knife-shaped transversal edges (15) and are welded to the internal (12) and the external (13) conductors. The current conductors (10) constituted by the foils (11), the internal (12) and the external (13) conductors are able to conduct rather high currents. The lamp, nevertheless, is of a simple, strong and reliable construction.
