Abstract: Stator of an electrical machine includes a stator lamination stack, having coil forms fastened thereto which each include an electrical coil. The coil forms are each pressed onto a tooth of the stator lamination stack. For the fastening of the coil forms to the teeth of the stator lamination stack, at least one fastening element is provided at the two end faces of the stator lamination stack, which fastening element includes a fastening arrangement which cooperate in a form-locking manner and/or force-locking with coil forms.

Abstract: Stator of an electrical machine are already known, having a stator lamination stack, having coil forms fastened thereto which each include an electrical coil. The coil forms are each pressed onto a tooth of the stator lamination stack, convex protuberances, which generate the dynamic compression, being provided on the teeth of the stator lamination stack. The inherent drawback here, however, is that the convex protuberances are expensive to manufacture. In the case of the stator according to the present invention, the fastening of the coil forms to the teeth of the stator lamination stack is simplified. It is provided in accordance with the present invention that at least one fastening element (9) be provided at the two end faces of the stator lamination stack (2) that includes a fastening means (10) which cooperate in a form-locking manner and/or force-locking with coil forms (6).

Abstract: A stator for an electric motor has phase potential bars and an insulating retaining element. The insulating retaining element includes a first component configured to accommodate the phase potential bars and to insulate the phase potential bars electrically from one another. The insulating retaining element additionally includes a second component which is separate from the first component. The second component, in conjunction with the first component, forms a trough that borders on the phase potential bars.

Abstract: A connecting arrangement for fluid-conducting tubes (1, 2) has a further fluid transporting component (16). The fluid-conducting tube (1, 2) has at least one collar (3, 4) facing radially outwardly which can be clamped against the further fluid transporting component (16) with the aid of a holder (5). The holder (5) has at least one U-shaped lateral receptacle (6, 7) formed by two arms (12). The predetermined length of the arms (12) is dimensioned such as to enclose more than half of the fluid-conducting tube (1, 2) during plastic deformation. The U-shaped receptacle (6, 7) has at least one relief region (13) in which holes, grooves, cavities or other material reductions are arranged. The cross section of the arms (12) changes little during deformation due to the relief regions because upset material can flow into the same.

Abstract: A mushroom-shaped semiconductor stripe laser, particularly with transversal, monomode light distribution and a double heterostructure comprised of a substrate, a laser-active zone, a cover layer and an electrically contacting metal layer for the cover layer with the cover layer being underetched such that a mushroom-shaped structure is formed in which the laser-active zone is constricted to a stripe-shaped region. The ratio of the width of the cover layer to the width of the laser-active zone lies in a range between two and five, and the cover layer is electrically conductively connected with the metal layer on its outer surface as well as on at least one of its side surfaces.

Abstract: A semi-conductor laser comprising a crystal having a sequence of layers forming a heterostructure diode and which includes a laser active zone interposed between a pair of semiconductor layers. Each of these semi-conductor layers has a band gap which is greater than that of the layers within the laser active zone. The laser active zone includes a first semiconductor layer having a given band gap, and at least second and third semiconductor layers each having a band gap which is greater than that of the first layer. The first layer is contiguous with and interposed between semiconductor layers each having a band gap which is greater than that of said first layer and forms a pn-junction with one of those contiguous layers. A strip-shaped region of a uniform conductivity type diffused from the surface of the crystal penetrates into at least one layer of the laser active zone but does not penetrate into the first layer.
