A fan has an electronically commutated external-rotor motor serving to drive it. The motor has an internal stator (20) having a stator lamination stack (64) and a winding arrangement (66; 164, 166, 168, 170) associated with the stack. The internal stator has a central opening (149) for journaling a shaft (42). The fan further has a permanent-magnet rotor (28) separated from the internal stator (20) by a magnetically effective air gap (99). The internal stator (20) has a plastic coating (56, 58) that surrounds the stator windings, forms a bearing tube for journaling the shaft (42), and defines a wall element (62), implemented integrally with the plastic coating (56, 58), forming a compartment or cavity (108) for electrical components (112) of the motor. The plastic coating, bearing tube and compartment are preferably molded in a single working step.

The invention relates to a method for monitoring the wear of a pair of hand pliers with which crimping elements can be pressed onto a workpiece and a particular degree of crimping mp, to be obtained by actuating the pliers, set using a presetting device. An arrangement is described for carrying out this method, as is a pair of hand pliers implementing the method. The method includes: counting each actuation of the hand pliers and linking to the degree of crimping mp that has been set; reading out a wear prognosis value Vt, from a memory, for the degree of crimping that has been set; determining a total wear value V by adding up the wear prognosis value Vt for each actuation; verifying whether the total wear value reaches or exceeds a defined threshold value VG, and issuing a calibration request if necessary.

A circuit arrangement for a data processing system is configured to process data in a plurality of modules. The circuit arrangement is configured such that each module is provided with at least one clock pulse, a time base and a base of at least one additional physical variable. The circuit arrangement also comprises a central routing unit to which the plurality of modules are coupled and via which the plurality of modules can periodically exchange data amongst themselves, based on the time base and/or the base of other physical variables. Each module is configured independently and parallel to other modules of the plurality of modules in order to process data. The circuit arrangement is employed in a corresponding method.

The invention relates to a method for the riveted fastening of an accessory to a plastics fuel tank (11, 12), the riveted fastening taking place at the time of the production of the tank by extrusion blow-moulding of a split tubular preform or two web-like extruded preforms made of thermoplastic material by using a multi-part die after or during the moulding of two complementary shells. The accessory (4) has been provided or is provided with at least one opening. The method according to the invention is characterized in that the riveted fastening takes place by means of at least one prefabricated rivet pin (9) made of thermoplastic material. The rivet pin has been obtained in a separate production process, for example by injection-moulding.

The image to be superimposed is imaged into the beam path of the aiming optics by the at least one diffractive optical coupling element and the least one diffractive optical decoupling element.
摘要:
Semiconductor layer material, e.g., for use as an emitter material for a heterojunction solar cell, is formed as a stack made of multiple first layers and second layers alternatingly situated one on top of the other. The first layers is made of an elementary, polycrystalline semiconductor, and the second layer is made of a substoichiometric electrically insulating compound, e.g., an oxide, carbide, or nitride, of the semiconductor. The interfaces between the first layers and the second layers are irregularly structured by a temperature treatment in such a way that microcontact areas are formed between adjacent first layers, which are separated from one another by a second layer.
摘要:
A method and arrangement reduce an interference which is caused in a received signal from a reception antenna by a transmitted signal with transmitted data which are distributed stochastically over time from a transmission antenna which is physically close by. The transmission of the transmitted signal from the transmission antenna is activated and deactivated by a control signal from a control circuit over time such that reception dropouts in the received signal which are caused by the interference are corrected by an error correction unit for the received signal.
