Abstract: A method of coating core having a metal surface with a uniform thickness, smooth, thin layer of fluorinated polymer calls for inserting the core into a sleeve of the polymer. The sleeve has an inner diameter slightly smaller than the outer diameter of the core so that the sleeve stretches to form a skin-tight fit over the core upon insertion. The assembly of sleeve and core is then subjected, in sequence, to aging under vacuum at a temperature below the softening point of the polymer prior, heating to a temperature above the softening point, and cooling below the softening point to thermally bond the fluorinated polymer to the metal surface. A firm bond is achieved without additional adhesive components or etching of the surface. A fuser roll for suitable for electrophotographic copy machine service can be prepared by this method without the need for a separate, post-bonding burnishing step to smooth the exposed surface of the fluorinated polymer layer.

Abstract: A drive system, in particular for a vehicle, includes an electric machine, by means of which a shaft can be driven to rotate and/or electrical energy can be obtained when the shaft rotates. The electric machine includes a stator arrangement with a stator interaction region and a rotor arrangement with a rotor interaction region. The rotor interaction region is coupled or can be coupled to the shaft for common rotation by means of a carrier arrangement. A torsional-vibration damper arrangement includes which is formed at least in part by said carrier arrangement, a primary side and a secondary side which can rotate, counter to the action of a damper element arrangement, about an axis of rotation (A) with respect to the primary side.

Abstract: An apparatus and process for the free-forming manufacture of three-dimensal components. A powder-binder mixture, or a material with a high melting point, is plasticized or made molten, by raising the temperature inside a process chamber. The resulting molten material is discharged under pressure through a nozzle which is arranged at the end of the process chamber. The material inside the process chamber is deposited in layers. The processing direction and processing speed of the nozzle are programmed. An embodiment of the invention is disclosed in which a non-molten powder is deposited and supported by the deposition of a second powder alongside the non-molten powder.

Abstract: Basic cells (GZ) that are composed of at least three p-channel transistors (TP) and of three n-channel transistors (TN) are employed for constructing a read-only memory. Only the outwardly disposed transistors (TP1, TP2) or, respectively, TN1, TN2) are employed for storing the information, whereas the inwardly disposed transistors (TN3, TP3) are not used. An information is stored in that the gate electrode (G) of one transistor (TP, TN) is connected to a word line (W), the drain electrode is connected to a bit line and the source electrode is connected to a fixed supply voltage (VDD, VSS) or is not connected thereto. The layout of the basic cell (GZ) is executed such that the gate terminals ensue in the inner region of the basic cell and the word lines (W) and bit lines (B) are conducted over the basic cell perpendicularly relative to one another. Read-only memories of arbitrary size can be realized by joining such basic cells in rows and columns.

Abstract: A gate array arrangement provides basic cells in a core region, with logic functions or storage functions being realized by wiring these basic cells. The basic cells are composed of six or seven transistors in CMOS technology, with three p-channel transistors (TR1) in a a first region (BE1) and three n-channel transistors (TR2) in a second region (BE2), with the terminals (GTA) of the gate electrodes (GT1, GT2) of the transistors being arranged between these two regions (BE1, BE2). A further transistor (TR3) that has a smaller channel width than the remaining transistors (TR1, TR2) is arranged outside of the region (BE2) for the n-channel transistors (TR2). The gate electrode (GT3) of the further transistor lies parallel to the electrodes (GT2) connected to the gates of the n-channel transistors (TR2) but is shorter. The terminal (GTB) of the gate electrode (GT3) of the further transistor (TR3) faces toward the line for the supply voltage (VSS).
