Abstract: A magnetic coupling is provided having two rings that are arranged concentrically in relation to one another, which are each mounted to be rotatable in relation to one another. An arrangement of at least three magnetic dipoles is respectively arranged on both rings, the magnetic dipoles facilitating magnetic coupling of the rings and a transmission of torque from a driving ring to a driven ring of the two rings. The magnetic dipoles of the arrangements at the driven ring and/or at the driving ring is/are aligned such that two like magnetic poles, which adjoin one another on the respective other ring, are always followed by an unlike magnetic pole, and the magnetic poles adjoining one another at the respective other ring are arranged in a manner corresponding to one another such that the two rings are magnetically coupled in an equilibrium position.

Abstract: An endoscope (1) with an endoscope shaft (3) in which an illumination device (11) and a rotatably mounted image sensor (12) are arranged in a distal region (8) is provided, and includes a handle (2) in which a rotatably mounted heat sink (16) is arranged, wherein the image sensor (12) is thermally connected to the heat sink (16), for conjoint rotation therewith, via a heat transmission element (15).

Abstract: A high-frequency transmission of data between functional units, which are mounted rotatably with respect to each other, of an endoscope, is permitted in which the functional units can be electrically insulated from each other. For this, an electric connecting element which, in a central flexible portion, is rolled up transversely with respect to the direction of transmission and is fastened by its respective end portions to the functional units is provided. An uninterrupted electrical connection with consistent quality of the signal transmission can therefore be obtained even when the functional units are rotated in relation to each other. By the rolling up of the central portion to form a winding, which is preferably configured in a self-supporting manner, a long term stable rotary degree of freedom is created in a very simple manner for the connecting element, with this degree of freedom permitting complex mechanical adjustment functions in the endoscope.

Abstract: A diode, e.g., a press-fit power diode for a rectifier in a motor vehicle, includes a semiconductor chip which is connected to a head wire and a base via solder layers. A plastic sheathing, which is situated at least in the chip area and includes a plastic sleeve, enables a hard casting compound to be used and establishes a mechanical connection between the base and the head wire and forms a housing together with the base. An undercut, which extends into the casting compound, and a gap between the sleeve and the edge of the base achieve a compact design. Bevels provided on both sides enable the diode to be pressed into the rectifier from two sides.
