摘要:
The invention relates to a closure and a method for connecting and opening saw cables (1), whereby the closure (4) is made up of several parts, which may be connected to each other, such as to rotate about at least two separate axes, by means of several bearings (13, 26, 27). The closure comprises two closure pieces (5, 6) with a separable rotating bearing (13) and a bearing lock (18) which may be opened, depending on the angular position of the closure pieces.
摘要:
An electrical machine, preferably a blower drive mechanism for a motor vehicle, having a shaft which is supported in at least two bearings with a specified axial play; a cylindrical bearing is secured in a bearing seat of an end shield and rests directly on the bearing seat. The cylindrical bearing has a cylindrical outer circumference, and the bearing seat is a sleeve with a cylindrical inside diameter, into which sleeve the cylindrical bearing is secured with a press fit on the outer circumference and is held axially in the bearing seat by the thus-attained frictional engagement. This has the advantage that more-precise adjustment of the longitudinal play of the armature is possible. Moreover, no additional components such as retaining springs are necessary.

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.
摘要:
A pencil, in particular for cosmetic purposes, is made by casting a stick composition into a tubular body, which forms the shaft of the pencil and is preferably seamless, in such a way that a ready-to-use exposed stick point is formed during casting.The shaft may be of wood or plastics. In the case of a wooden shaft, a solid wooden rod of twice the shaft length may be bored out and otherwise worked and then separated along a central plane transverse to the axis of the rod to form a pair of shafts into which the stick composition can subsequently be cast.

A DC motor (1), in particular for a blower device of a motor vehicle, having a pole housing (10), a plurality of contact elements (13) effecting the bonding to a collector (12), a pole housing opening (16) making it possible to feed electrical connection lines (18) through into the pole housing (10), and an interference suppressor (28, 28.1) serving to reduce and/or eliminate line-conducted electrical interference signals, in which the interference suppressor (28, 28.1) has at least one leadthrough capacitor (48), which is located in an electrical path of at least one connection line (18). The invention further relates to an electrical interference suppressor (28, 28.1) for an electrical device located in a housing, in particular for a DC motor (1) in a pole housing (10), as well as to the use of a leadthrough capacitor (48, 48.1) for interference suppression in a DC motor (1).
摘要:
An apparatus for measuring the viscosity of a fluid having a first rigid member extending from a body of semiconductor material and provided with a first conductive path and a second resiliently flexible member provided with a second conductive path and arranged in cantilever fashion over the rigid member. At least one of the conductive paths may be selectively energized to brig about relative movement between the rigid and flexible member. Subsequent deenergization of the path causes the resiliently flexible member to return to its initial position, the rate of return being measured to derive a signal representative of the viscosity. Also described are methods of carrying out the measurement and of fabricating the apparatus.
摘要:
A lipid-bearing preparation and method for preparing same in particular in the form of a stick or a workable paste, which is suitable for cosmetic uses, in particular in the field of decorative cosmetics for coloring and improving the appearance of the skin, the lips and the eyelids. The lipid-bearing preparation is in water-free form and contains in the lipid phase exclusively vegetable-base raw materials.
摘要:
A mini-fan (126) is implemented for installation in a recess (124) of a wall (122), which wall is equipped on the periphery of the recess (124) with a plurality of retaining members (128, 129). The fan has, for air guidance, a housing (136) that, in its installed position, projects with a housing portion (127) approximately complementary to the recess (124) of the wall (122) into that recess. Arranged on the periphery of that housing portion is at least one part (138) made of an elastomeric material, with which part the fan (126) is introducible, upon its installation with the part (138) made of elastomeric material with displacement along the wall (122), into the retaining members (128, 129), in order to bring that part (138), in the installed position, at least locally into sealing contact against the wall (122).
摘要:
A process is for material-removing machining, on both sides simultaneously, of semiconductor wafers having a front surface and a back surface, the semiconductor wafers resting in carriers which are set in rotation by means of an annular outer drive ring and an annular inner drive ring and being moved between two oppositely rotating working disks in a manner which can be described by means of in each case one path curve relative to the upper working disk and one path curve relative to the lower working disk, wherein the two path curves after six loops around the center have the appearance of still being open, and at each point have a radius of curvature which is at least as great as the radius of the inner drive ring.
