Abstract: A fuel injection pump for internal combustion engines having a cup-shaped pump housing and a pump head enclosing the housing. The pump head has a cylinder in which a pump piston, which is set into simultaneous reciprocating and rotary motion by a cam drive, in the course of which it simultaneously acts as a distributor, encloses a pump work chamber that is filled with fuel upon an intake stroke and communicates with one of a plurality of injection lines upon the supply stroke. The resultant reaction forces and moments are supported according to the invention via a roller race supported directly on the pump head, and as a result the induction of force to the pump housing can be avoided.

Abstract: 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.

Abstract: A monolithic integrated power transistor chip includes a plurality of transistor cells arranged in two opposite and mutually spaced rows. Each cell has emitter- and collector connection spots arranged side-by-side and connected to corresponding branch conductors directed by rows of connection points extending along opposite edges on the upper surface of the chip.

Abstract: 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).

Abstract: An electronic circuit device having a monolithic integrated power transistor is disclosed that comprises a parallel connection of a plurality of individual partial transistors (1, 2, 3, . . . , n). In order to stabilize the distribution of the sum current to the individual partial transistors (1, 2, 3, . . . , n) resistors (41, 42, 43, . . . 4n) are provided in their emitter lines. At least one of the resistors (41, 42, 43, . . . 4n) in the emitter lines of the partial transistors (1, 2, 3, . . . , n) serves as measurement resistor for producing a signal voltage proportional to the current to provide an electronic circuit device having current regulation or current limiting, as shown in FIG. 2.

Abstract: 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.

Abstract: The invention relates to a method and an apparatus for optimizing thermal treatment processes of fabrics, preferably textile fabrics, in tensioning, drying and setting machines. According to the invention, the apparatus for the thermal treatment of fabrics comprises individual sections, to which is conveyed heated air. The air leaves each section via outgoing air slits, which are provided with at least two measuring locations per section. The measuring locations enable determination of the difference of the outgoing air temperature of the sections. After determining the location of the dryness point by comparing the outgoing air temperatures with the predetermined temperature, the measuring point at which there exists no difference, or only a minimal difference, is determined. The characteristic point for reaching the predetermined temperature of the fabric is thus found which, together with the found maximum, determines the adjustability of the speed, the energy supply or the outgoing air temperature.

Abstract: 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.
