摘要:
An electro-acoustic transducer for a component operating with surface waves, in particular for a surface wave filter, in which, to suppress interfering excitation ensuing in the gap region adjacent an end of a finger, a variation of the gaps is implemented with regard to at least one feature selected from transversal arrangement, size and shape. Due to the slight dimension change of the position of the gap in comparison to the finger length, the desired primary excitation in the transducer remains approximately unchanged, however the interfering excitation is displaced or divided, and made ineffectual.

A hydrodynamic coupling device, especially a hydrodynamic torque converter, includes a housing which is rotatable about an axis of rotation, a turbine wheel mounted for rotation with respect to said housing, and a bridging clutch for transmitting torque between the housing and the turbine. The bridging clutch includes a first friction element which is essentially fixed against rotation with respect to the housing, and at least one second friction element which is essentially fixed against rotation with respect to the turbine, the friction elements having respective friction surfaces which can be brought into contact with each other. A first channel, provided in one of the friction surfaces, has first channel sections with radially closed inner ends and second channel sections with radially closed outer ends. A circumferentially extending second channel, provided in the other friction surface, establishes a fluid conducting connection between the first channel sections and the second channel sections when the first friction surface contacts the second friction surface. For every part of the friction surface which is opposite the second channel in a first relative rotational position, a second relative rotational position is provided in which this same part is in contact with the friction surface having the second channel.

A sun visor (10.1) for a vehicle, having a holding unit (12.1) which can be fastened to the interior, and an antidazzle unit (14.1) which is arranged on the holding unit (12.1), has a visor body (16.1) of essentially planar design and can be moved, for antidazzle purposes, from a retracted position into a functional position, the sun visor being arranged in particular between a driver's sun visor and a front-passenger's sun visor, is distinguished in that the visor body (16.1) has at least one moveable surface unit (18.1) which increases the surface of the visor body (16.1), when the visor body (16.1) is moved from the retracted position to the functional position, and conversely reduces the surface of the visor body (16.1) when it is moved from the functional position into the retracted position.
摘要:
The invention provides a steering system comprising a controlled element which is movable in a neutral area comprising a neutral position and in areas on opposite sides of the neutral area based on a steering input and a handle for requesting a desired position for the controlled element. The handle is movable between set-points in a center zone comprising a center set-point and set-points on opposite sides of the center zone. Furthermore, a steering unit is arranged to receive set-points from the handle, to determine a corresponding controlled position of the controlled element, and to move the controlled element to said controlled position. In order to prevent or reduce jerks, the steering unit is adapted to vary a speed by which the controlled element is moved to the controlled position. The speed is variable in dependence of the received set-point.

摘要:
A torque transmission device of a motor vehicle which transmits torque from an internal combustion engine to a torque converter, wherein the torque transmission device includes transmission part connected to the torque converter in a first radius region having a quantity of fastening elements lying on a first radius and connected to the internal combustion engine in a second radius region having a quantity of fastening elements lying on a second radius. To reduce loading of the fastening elements, the transmission part is provided with recesses in the first radius region and/or in the second radius region that extend at least partially over the first or second radius region and lessen the axial rigidity of the transmission part.
摘要:
A SAW filter has two DMS tracks. Each DMS track includes six converters, with two converters each acting as input or output converters. The two DMS tracks are electrically connected in series by way of four pairs of coupling converters and the associated coupling lines. A common inner ground line is provided between the two DMS tracks, which extends over the entire length of the DMS tracks and crosses the coupling lines. The input converters of the first DMS track are connected to an asymmetrical port, while the output converters of the second DMS track are connected to a symmetrical port.
