A solar cell includes a waveguide core for receiving light, a first layer formed on the waveguide core, a second layer formed on the first layer, a third layer formed on the second layer, first metalization coupled to the first layer, and second metalization coupled to the third layer. The first layer comprises a first optical film which varies in an index of refraction in a lateral direction between a first input end where the light is received and a first output end where the light is emitted. In some embodiments, wherein one or more of the first, second, or third layers has a tapered lateral thickness. In some embodiments, the first, second, and third layers form a PIN device. In some embodiments, the waveguide core has a first index of refraction that is lower than respective indexes of refraction for the first, second, and third layers.

The invention relates to a spindle drive for an adjusting element of a vehicle comprising a drive motor with a spindle-spindle nut gear arranged downstream for producing a drive force along a geometric spindle axis, wherein two connectors for transferring the drive force are provided, wherein an internal housing connected to the one connector and an external housing connected to the other connector are provided, and wherein during the motorized adjustment, the internal housing runs in a telescopic manner. It is proposed that at least one of the two housings, is designed to be at least in two parts and is provided via a first axial housing portion of a first housing part made of a first material and via a second axial housing portion of a second housing part made of a second material.

An actuator (100) for a molding system (900) is disclosed. The actuator (100) includes a linear actuator (102). The linear actuator (102) is configured to move a payload (160) relative to a support structure (170). The linear actuator (102) is connectable to the support structure (170) and the payload (160). The actuator (100) also includes a first compensator (104). The first compensator (104) is configured to compensate for a relative misalignment between the linear actuator (102) and the payload (160). The actuator (100) further includes a second compensator (106). The second compensator (106) is configured to compensate for a relative misalignment between the linear actuator (102) and the support structure (170).

A drive device serves for adjusting an operating element for a valve, a throttle, a blow-out preventor or the like, in particular in the field of gas and oil production, the operating element being actively connected to at least one driving motor via a drive train, and at least one transmission changing unit being arranged in the drive train for converting a revolution of the driving motor into a revolution of the operating element and/or a revolution/linear motion converter being arranged for converting the revolution of the driving motor into a linear motion of the operating element. In order to also have a very compact design in case of a high possible performance and to simultaneously permit a good thermal distribution within the drive device, so that separate cooling devices for carrying off the generated lost heat are superfluous, the drive train comprises at least one essentially disk- or wheel-shaped revolution introducing device which is actively connected with at least two drive shafts driven by separate driving motors.

A linear actuator comprises a motor having an output. An end block is connected to a casing and to the motor and has a counterbore at a distal end with a bearing seated and retained in the counterbore. A coupling assembly couples the output shaft of the motor to a threaded shaft for transmission of the rotational output to the threaded shaft. A sliding tube is in sliding arrangement with the inner cavity of the casing for moving in translation relative to the casing.
