Abstract: A method is provided for producing deep substantially vertical structures in silicon substrates, wherein in a first step, the silicon substrate is anisotropically plasma etched to a first predetermined depth, thereby creating a first structure. Subsequently, the surface of the substrate is covered conformally with an etch-resistant coating, and the horizontal parts of said coating are selectively removed. Following this removal, the substrate is anisotropically plasma etched at low temperatures to a second predetermined depth with a mixture of SF.sub.6 /O.sub.2, whereby a second structure is created. Finally, the vertical parts of the coating are removed.

Abstract: A dual-mass flywheel comprises a primary mass (7) which is adapted to be fastened to a crankshaft (3) of an internal-combustion engine concentric to an axis of rotation (1) and a secondary mass (9) which is mounted for rotation relative to the primary mass (7) around the axis of rotation (1).

Abstract: The torsional shock absorber which is preferably suitable for a dual-mass flywheel comprises an input part (1) and an output part (21) which is rotatable round a common axis of rotation. Between control edges (43) of the input part (1) and control edges (41) of the output part (21), long load springs (23) designed for load running are arranged in an annular channel (15) which surrounds the axis of rotation and couples the output part (21) torsionally elastically to the input part (1). The output part (21) or optionally spring pots (25) provided at the face ends of the load springs (23) carry a peripherally resilient intermediate element (45) which projects beyond the control edges (41) of the part guiding the intermediate element (45) and rests on the control edges (35) of the other part. The control edges of these two parts are spaced from one another in the rest position of the torsional shock absorber, this spacing forming the operating range of the idling suspension.

Abstract: A process or apparatus can control thread provision in a warp knitting machine by means of a computer (6). The computer operation involves pattern data (MD) supplied as a sequence of numbers. These numbers are provided to a recognition routine (ER), which for every warp course (line W) determines the lapping type (LA) that should be formed and the shogging distance (SW) prescribed. Tables are stored for providing a thread provision value (FZ) for each combination of lapping type (LA), thread take-off value (WA), and a shogging distance (SW). Based upon (a) the determined lapping type, (b) the inputted fabric take-off value, (c) the inputtable external operating parameters or influences, and (d) the determined shogging distance, the thread provision value for this warp course is read out and utilized for controlling thread provision.

Abstract: The invention relates to a method for removing a motor vehicle friction clutch of modular design and to friction clutches suitable for this method. The arrangement of openings in the clutch plate and the use of specific tools for venting the friction clutch enable the clutch plate to be orientated such that the fastening screws may be opened by corresponding screwdrivers through the slots of the spring tongues of the diaphragm spring and through the openings in the clutch plate. This enables a clutch module to be exchanged completely after damage or normal wear.

Abstract: The invention comprises a PECVD method for the deposition of refractory metal layers or layers containing refractory metal by the in situ formation of refractory metal fluorides. For this purpose, an etch gas, such as CF.sub.4, NF.sub.3, SF.sub.6 etc., is introduced into a plasma deposition chamber which comprises a cathode, with a refractory metal sheet electrically connected thereto, and an anode carrying wafers.In a preferred example, CF.sub.6 is introduced into the chamber and, via a gas shower, into a cathode region. After ignition of a plasma, the ionized etch gas acts on a tungsten sheet, generating WF.sub.x ions that diffuse towards a target with wafers. The WF.sub.x ions thus produced are suitable for the deposition of a tungsten layer or a layer containing tungsten on silicon wafers.

Abstract: The magnetic disc comprises a magnetizable layer (1) to which an adhesion promoting layer (4) and thereto a lubricant film (5) are applied. Onto the substrate of the magnetic head (2) an adhesion reducing layer (9) is deposited. The apparatus can also show only one adhesion-influencing layer. The layers (4) and (9) are formed by the reaction of a sililating agent with reactive groups on the surface of the magnetizable layer (1), or of the substrate of the magnetic head (2), respectively. The sililating agents used differ in their terminal groups of which one category produce van der Waals bonds to the lubricant molecules, and the other is chemically indifferent relative to the lubricant molecules.The two layers (4) and (9) are made e.g. by the spin-coating of a solution of the sililating agent, and subsequent drying.The apparatus ensures a homogeneous coating of the magnetizable layer (1) with lubricant, and it prevents the pick-up of lubricant by the substrate of the magnetic head (2).
