Abstract: A configuration and method for bonding a thin metal layer to two workpieces, e.g. solar cells and film-backed/reinforced small contact strips including: (i) the backing film is removed from the solar cell; (ii) the two films/layers are pressed together; and (iii) the two parts are irradiated from the side of the rear contact of the thin-film solar cell. Preferably two or three laser treatment steps are used for removing the backing film of the thin-film solar cell in an ablation process by means of a short-pulse laser and riveting the first metal layer to the second metal layer by irradiating the same by means of a long-pulse laser.

Abstract: The invention relates to a displacement sensor (1a; 1b; 1c) with at least one magnetoelectric transducer element (5) and a magnetic circuit composed of at least one flux conductor (3, 4; 9, 10; 14, 15) and at least one magnet (2; 11), which is small in size and with which the influence on the magnetic flux caused by the movement of an element is capable of being measured with the transducer element (5). During the displacement measurement, the flux conductors (3, 4; 9, 10; 14, 15) and the transducer element (5) are situated in an unchanged position in relation to each other, whereby these parts (3, 4, 5; 9, 10; 14, 15) and the at least one magnet (2; 11) are capable of being moved relative to each other. A change in the magnetic field that is capable of being evaluated by the transducer element (5) is induced by a change in the air gap (d) in the magnetic circuit while the magnet (2; 11) moves.

Abstract: A device for restoring a rotary member into a defined normal position, with a spatially stationary fixed catch, which predetermines the normal position, and a driver catch, which is coupled to the rotary member and can be moved past the fixed catch, each of which has stop surfaces embodied on each of its opposing sides, and with a clamping spring, which encompasses the catches in a prestressed fashion with two bent spring legs, in order to prevent a rotary play between the clamping spring and the catches in the normal position, and an elastic spring element in at least one leg section of the spring legs extending across the stop surfaces of the catches, which spring element is supported against the associated stop surface with a spring force that is less powerful than the prestressing force of the clamping spring.

Abstract: A measuring instrument (10) for contactless ascertainment of a rotation angle is made up of a support plate (12) that is comprised of magnetically nonconductive material and serves as a rotor. A permanent magnet (15), which is embodied as planar, is disposed on the support plate (12) and its polarization direction is aligned diametrically to the axle (11). If the Hall element (20) is asymmetrically disposed, i.e. if the Hall element (20) describes an elliptical rotary motion in relation to the permanent magnet (15), then a steeply decreasing region and a flat region are produced in the curve of the output signal. No magnetic flux conducting parts are required in the measuring instrument (10). Furthermore, it is very small and relatively easy to incorporate into systems and devices.
