IPC: H02K7/116

Abstract: Powerful electric motors, especially for driving motor vehicles, require enclosed motor housings in order reliably to prevent ingress of dust and liquids into the housing interior. However, it is disadvantageous in this case that the temperatures produced because of the development of heat lead to pressure fluctuations in the housing interior, which can force oil out of the bearings of the rotor shaft. Rapid bearing wear caused by this can lead to rapid failure of the electric motor. This is prevented according to the invention by at least one opening (37) being arranged in the wall part (11) or base part (9) of the motor housing, which opening (37) is closed by a cover made of a material which is impermeable to liquid but is permeable to gas. In consequence, simple pressure equalization is achieved between the housing interior of the motor housing and the gearbox housing or between the housing interior of the motor interior of the motor housing and the outside air. According to the invention, high, constant efficiency of the electric motor is ensured for a long time since it is no longer possible for any pressure fluctuations, which have a damaging effect, to occur in the housing interior. <IMAGE>

Abstract: In the process for the preparation of a melt for the production of mineral fibres, the raw material (6) to be melted is introduced in the form of a pile of loose material so that it forms an inclined pile surface (7). In order to form a melt zone, at least part of the pile surface (7) is subjected to the melting temperature in at least one combustion chamber (8). The melt flowing out in the region of the pile surface (7), forming a melt surface crust (7a), is collected in a collection chamber (11) on the base of the combustion chamber (8) and transported out to the outside for further processing. In order to provide a process by means of which the melt output can be significantly increased, it is proposed that the melt surface crust (7a) of the pile surface (7) is broken up in at least one region from the inside outward. <IMAGE>

Abstract: A method of manufacturing semiconductor devices whereby first a Ti layer (8) and then a TiN layer (9) are deposited on slices of semiconductor material (20). The slices are placed on a support (30) one after the other in a deposition chamber (22), the support being positioned opposite a target of Ti (32) surrounded by an annular anode (31). Material is then sputtered off the target by means of a plasma (35) generated near the target. The plasma is generated in Ar during deposition of the Ti layer and in a gas mixture of Ar and N₂ during deposition of the TiN layer. After the deposition of the TiN layer, before a next slice is placed in the chamber each time, the target is cleaned during an additional process step in that material is sputtered off the target by means of a plasma generated in Ar. The additional process step is ended the moment the target has regained a clean Ti surface again. It is achieved by this that an extra Ti layer comprising nitrogen is indeed deposited on the TiN layer during this additional process step, but that this is as thin as possible and accordingly contains as little free Ti as possible. Undesirable chemical reactions between free Ti and the conductive layers deposited on the layer comprising nitrogen are suppressed as much as possible thereby.

Abstract: The assembled endoprosthesis is in a radially tensioned state in a cylindrical space (14) and lies with a proximal region (A) in a first external catheter (3) and with a distal region (B) in a second external catheter (30). In order to release the endoprosthesis (1), for example in a vessel (11), the second external catheter (30) is initially retracted. The endoprosthesis (1) is then still retained in the first external catheter (3) by friction and can be folded back by advancing the second external catheter (30), and can thus be repositioned. The endoprosthesis (1) is finally released by retracting the first external catheter (3). Since the friction is divided up over at least two external catheters (3, 30) it is also possible to release endoprostheses (1) which have a high friction on the outside to the external catheter, for example due to a coating, high expansion force or large length. <IMAGE>

Abstract: Hitherto, plastics have been removed from metallic microstructures by irradiation and, if necessary, subsequent treatment with solvents, by aggressive solvents or treatment at elevated temperatures; this can impair the quality of the microstructures, or the microstructure can be considerably modified or destroyed. The novel process allows the plastics to be removed under gentle conditions. The metallic microstructure is treated with a high-boiling fluid at above 140@C for from 10 to 90 minutes and subsequently rinsed with water. Suitable fluids are oligomers of ethylene glycol, short-chain diols or dicarboxylic acid esters. Such fluids do not attack the metal and do not allow swelling of the plastics to be removed. The production of metallic microstructures and the casting of microstructure elements from plastic by means of metallic microstructures can be carried out using plastics which are desirable per se, but which can only be used to a limited extent, or not at all, if the novel process is not used.
