Abstract: A positioning device (10; 50; 60) for positioning wire ends (14) in the manufacture of an electrical machine (12) has a positioning unit (13) which has an alignment element (22a) and a counter-alignment element (22b) which are arranged one above the other in two parallel planes (16, 18) and can be displaced relative to each other along a displacement path (34), being at least partially superimposed or superimposable. Thereby, the alignment element (22a) has at least one through recess (24a) and the counter alignment element (22b) has at least one counter through recess (24b), which are arranged and designed in such a way that a clear positioning passage (99) perpendicular to the two planes (16, 18) of the alignment element (22a) and the counter-alignment element (22b), through which the at least one wire ends (14) can extend and the cross-sectional area of which can be varied by displacing the alignment and counter-alignment elements (22a, 22b) with respect to each other.

Abstract: A photovoltaic module has a number of solar cells, which respectively include a contact structure on a pre-processed silicon wafer, which has a number of linear contact fingers disposed in parallel in a first direction and at least one bus bar disposed perpendicular to the first direction. The bus bar extends over the contact finger in a second direction and has a respective contact surface in the region of the contact finger, which protrudes above the contact finger in the second direction and is electrically connected to the contact fingers. At least one cell connector is provided for connecting the solar cells, which extends over the bus bar of at least one solar cell and is electrically connected to the contact surfaces of the bus bar, wherein the width of the cell connector is smaller than the length of the contact surface in the first direction.

Abstract: A control unit for a machine tool or a coordinate measuring apparatus includes a control console having at least one operator-controlled element and a display screen. The operator-controlled element and the display screen are connected to a computer of the machine tool or the coordinate measuring apparatus. A converter expands or compresses a display screen signal outputted by the computer so that the entire content of the display screen on the control console is filled out with the display screen content of the computer independently of the image resolution of the display screen signal.
