The invention relates to a device (10) for accommodating an electric motor (30), particularly a blower motor for a heating or air-conditioning system, comprising an essentially pot-shaped accommodating housing (12) serving as a motor housing and having an accommodating opening (32) in which the pole casing (46) of an electric motor (30) can be inserted while at least partially projecting inside. The inventive device also comprises a retaining flange (14) mounted on the accommodating housing (12) and serving to fasten the motor housing (12) to a supporting element, and comprises a control and regulating unit (20) mounted on the retaining flange (14) and serving to operate the electric motor (30). The invention provides that the accommodating housing (12) has, in the peripheral direction, at least one flattened area (36,40), which differs from a circular shape while corresponds with at least one flattening (54) of an outer contour of the control and regulating unit (20). The invention also relates to an electric motor (30), particularly a direct-current motor having at least two permanent magnetic poles (44) and a pole casing (46) serving as a magnetic return ring and having at least one flattening (55) on the periphery of the pole casing, for use in a device (10) of the aforementioned type.

A heating unit for a vehicle features a radial fan (100) having a housing (110), which housing has an air inlet (116) and an air exit opening (118). The heating unit has an air-directing device (140) that guides an air flow in a pressure chamber (115) of the housing (110) to the exit opening (118). Arranged in the housing (110) is a radial fan wheel (130) that serves to generate a flow from the air inlet (116) via the pressure chamber (115) to the air exit opening (118). Also provided is an electrical heating element, e.g. a PTC (Positive Temperature Coefficient) heating element (125), that serves to transfer heat to the air flow generated by the fan. Air-directing elements (632, 634, 636, 638) are provided between the exit opening (118) and the heating element (125), in order to generate an air flow having a more uniform (680) velocity distribution.
摘要:
A semiconductor wafer has a front surface and a back surface and flatness values based on partial areas of a surface grid on the front surface of the semiconductor wafer, which has a maximum local flatness value SFQRmax of less than or equal to 0.13 &mgr;m and individual SFQR values which in a peripheral area of the semiconductor wafer do not differ significantly from those in a central area of the semiconductor wafer. There is also a process for producing this semiconductor wafer, wherein the starting thickness of the semiconductor wafer is 20 to 200 &mgr;m greater than the thickness of the carrier and the semiconductor wafer is polished until the end thickness of the semiconductor wafer is 2 to 20 &mgr;m greater than the thickness of the carrier.

Described is a cosmetic pencil (10) having a casing shank portion (12) and a casing front portion (14). A cosmetic stick (24) is displaceable by of a drive element (22) in relation to the front casing opening (40) of the casing front portion (14). In order to be able to move the cosmetic stick (24) both out of the casing and also back into the casing, the drive element (22) is in the form of a tubular stick holding member (26) which is arranged in the casing front portion (14) movably axially in opposite directions. The cosmetic stick (24) which projects out of the stick holding member (26) is fixed with a rear fixing portion (42) in the stick holding member (26). In order to ensure freedom from play at any time between the cosmetic stick (24) and the casing front portion (14) or the casing opening (40) thereof, the peripheral surface (34) of the cosmetic stick (24) is steplessly aligned with the outside surface (32) of the stick holding member (26), wherein the outside diameter of the peripheral surface (34) of the cosmetic stick (24) and the outside diameter of the outside surface (32) of the stick holding member (26) corresponds to the inside diameter of the casing opening (40) of the casing front portion (14) of the cosmetic pencil (10).
