    摘要: A power transistor monolithic integrated structure produced by a bipolar-epitaxial technology includes a plurality of parallel connected transistor cellular structures each containing at least one component transistor. The base of each component transistor is coupled to a common base control conductor via a protective resistor and a fuse link which melts in the event of a defect in the transistor cell. Another fuse link is incorporated in the branch conductors leading from the collectors of respective component transistor to a common conductor web mounted on the surface of the transistor chip. All transistor cellular structures are electrically isolated one from each other during the manufacturing process.

    摘要: A monolithically integrated precision reference voltage source by the bandgap principle, suitable for a wide temperature range, is proposed, in which the parabolic course of the temperature response curve of the reference voltage is linearized by process means available in the monolithic integration, dispensing with additional active components such as transistors or diodes. The precision voltage reference source includes two resistors (21, 22), which are represented by the N-doped emitter diffusion zone.

    摘要: A current regulator, preferably constructed in accordance with monolithic integrated technology, for high currents is proposed, whose output current (I) is a function of an input quantity (E). In this case the output current (I) is less in a range of the input quantity (E) different from a value of zero than the value given in this range by the functional relationship between the input quantity (E) and the output current (I).

    摘要: In a process and apparatus for monitoring thread breaks without touching the thread, the stochastic electrical charge of the moving thread is detected without contact by means of a metallic plane electrode disposed at the textile machine close to the moving thread. The change of potential upon the occurrence of a thread break is amplified in a high input resistence amplifier. The output of the amplifier is connected to the threshold device directly or by a capacitor. A reference potential is connected to the threshold device input, and the threshold device outputs a binary signal for indicating the condition of the thread.

The device for activating and deactivating the transistor power end stage includes a comparator (16) for comparing a saturation voltage (U.sub.SAT) of the transistor power end stage (14) picked up between the transistor power end stage and the excitation winding with a reference voltage (U.sub.ref) to provide a comparison output and a pulse width modulation circuit (22) for controlling the transistor power end stage (14) to vary the predetermined pulse width of the pulsed excitation current according to the comparison output so that the transistor power end stage (14) is not damaged by short circuits.
