Abstract: A method for assembling an electric motor (10) having a stator (34) and a rotor (32). It is endeavored to keep the air gap (38) as narrow as possible, in order to achieve good efficiency of the motor (10). However, component tolerances and assembly errors require generous dimensioning in order to avoid possible contact between the stator (34) and the rotor (32). To improve the accuracy of assembly, is proposed, during the insertion into one another of the rotor (32) and the stator (34), a centering aid (40, 42) is introduced into the air gap (38) at at least three points, the rotor (32) and the stator (34) are subsequently fixed in relation to one another and finally the centering aid (40, 42) is pulled out through openings (48) in the motor housing (20, 30).

Abstract: The invention relates to an indicating instrument, in particular for a motor vehicle, having a housing with a front frame holding a cover pane, and an elastic spacing element arranged between the cover pane and front frame, and to a method for connecting the cover pane to the front frame. In order to ensure a reliable connection between the cover pane and front frame which is without play, the invention proposes the spacing element be placed in an axial cutout which is arranged in the region of the circumference of the front frame and faces the cover pane, and in which the cover pane can engage. The method consists in that in a first step the spacing element is inserted into the axial cutout in the front frame, and in a second step the cover pane is pressed into the axial cutout against the spacing element.

Abstract: A method for check the phase adjustment of a camshaft, in which the present phase angle of a variable phase camshaft can be detected reliably. A first value which corresponds to the actual noise level of the internal combustion engine is determined during a predetermined evaluation window and is compared with a second value, which corresponds to the actual noise level after phase adjustment of the camshaft, with the operation of the phase adjustment of the camshaft being assessed as a function of this comparison.

Abstract: The invention relates to a method for producing a housing (12) for a throttle valve connection piece (10), which housing is to have particularly high dimensional stability. For this purpose, the housing (12), which has a throttle orifice (16) for a throttle valve (20), is produced from plastic (14) by the injection molding method, plastic (14) being partially injected around a metal cylinder (28) which, at least in the region of the throttle valve (20), forms the throttle orifice (16). In this case, before the injection molding method, an expanding mandrel (50) is expanded against the inner face (33) of the metal cylinder (28). During the injection molding method, the inner face (33) of the metal cylinder (28) is supported at least partially by the expanding mandrel (50). After the injection molding method, a reduction in the outer circumference (80) of the expanding mandrel (50) is carried out in order to remove the expanding mandrel (50) from the interior (70) of the metal cylinder (28).

The moving element (6) is surrounded by a stub pipe (4), a functional element of the actuator (18) and the stub pipe (4) being connected to one another in a heat-conducting manner.

Abstract: In an indicating instrument, especially in a motor vehicle, having a cover glass (4) that appears dark and, under incident light, prevents any view of a dial (3) arranged at a distance behind it, and having at least one light source (8) arranged behind the dial (3) to transilluminate said dial (3) and therefore render the dial (3) visible through the cover glass (4). In order to prevent the dial (3) becoming visible when there is only incident light, the transmission of the dial (3) is matched to the transmission of the cover glass (4). To this end, in particular, the dial (3) is provided with a low transmission.

Abstract: A method for optically determining the position of a movement element optically includes introducing the light emitted by a light source into an optical conductor which causes attenuation of the light. A light output coupler that moves in accordance with the position of the movement element couples out the light from the optical conductor and feeds the attenuated light to a light detector. Using the ratio of the light intensity emitted by the light source and that registered by the light detector, the attenuation of the light is determined and the position of the movement element inferred therefrom. The sensor is usable in an aggressive environment or one susceptible to interference because of the light source and the light detector may be arranged remote from the movement element.

Abstract: In a pointer-type instrument (1) having a pointer with a pointer shaft (5) that deflects a pointer vane (2), power is supplied to a light source (3), which is connected to the pointer for rotation in common, by a flexible, spiral film (11) provided with conductor tracks (12, 13). For this purpose, the pointer shaft (5) has an enlargement (9), which supports the film (11) and secures it against sliding off axially. As a result, the film (11) can be made particularly thin, thereby making it possible to reduce the driving torque required to deflect the pointer shaft (5).
