Title: Simultaneous metal salicide and local connection structure production
Inventor: NAEM ABDALLA ALY
IPC: H01L21/768
Filed: 1997-09-23
Abstract: A process is claimed for simultaneously forming metal salicide and a local connection structure in an integrated semiconductor structure, in which spaced source/drain regions are formed in an active silicon substrate region, defined by adjacent field oxide regions, to delimit a channel region above which a gate oxide layer and a gate region are formed, followed by forming oxide sidewall spacers on the gate oxide layer and applying a conductive element. The process involves (a) forming a high melting metal layer (10) and then a high melting metal nitride layer (12) on the structure; (b) carrying out rapid thermal processing to form high melting metal salicide on the source/drain regions and on the gate region; (c) forming a local connection mask for protecting part of the high melting metal nitride layer (12) and underlying high melting metal, this layer part extending from above a selected zone of a source/drain region to the conductive element and defining a local connection region; (d) removing the unprotected portion of the high melting metal nitride layer (12) and underlying high melting metal; (e) removing the mask; and (f) carrying out a second rapid thermal processing to convert the underlying high melting metal of the local connection region into high melting metal nitride.

Title: Generating electrical energy from rotary movement of stub axles carrying rail vehicle wheels
Inventor: RASTI MAHMUD KESCHWARI DIPL IN
IPC: H02K11/00
Filed: 1997-11-03
Abstract: Electrical energy is produced by a generator with the same axis. The generator has a stator fixed to the vehicle frame and a rotor located on the stub axle with permanent magnets distributed around the periphery. Apart from the generation of electrical output energy, electrical energy for the measurement of the speed of at least one wheel is generated.  The electrical output energy is generated exclusively via the induction between the rotor equipped with permanent magnets and the stator. The measurement energy for the speed measurement occurs by separate sensors that can be influenced by a constant magnetic field between the rotor and the sensors. An Independent claim is also provided for the electrical energy generating circuit.
Patent DE-19758185-A1 (DE)
Title: Flexible multilayer casting mold producing e.g. multicolor moldings
Inventor: PANIER BURKHARD DIPL ING
IPC: B29C33/38
Filed: 1997-12-30
Abstract: Individual mold sections for the model, enclose one or more flexible, internal, separate molds (1,2,4). Close inspection of the illustration, reveals a dolphin mold with inner sections entirely or partly enclosed by a flexible, outer, separately filled mold (3). The auxiliary molds rest close against the outer mold. Edges and centers of individual layers are entirely- or partly- bonded, especially adhered or welded. Surfaces to be joined offer mutual support or are only separated by a thin sheet. Preferred features: each sectional mold has at least one filling gate (5,6,7,8), for filling with various materials. These have diverse locations. They are sufficiently large, to be rolled up and closed. This enables pressure control inside each mold section. Filling gates of molds are arranged such that the mold can also be rolled up with them. Repeated opening and closure is possible. Layered post-filling is feasible, producing heterogeneous, especially multicolor models. There is a bead around the filling gate. A slotted rod or strand can be used for pinching-off and rolling; it is made of plastic or metal. Once rolled, this can be bent back to prevent unrolling. Sectional molds differ in elasticity and expansion coefficient, from the main mold. Material differences, thickness variation and inlays achieve reinforcement or constriction in the mold.

Title: Production of aldehydes and alcohols via catalyzed hydroformylation of olefins
Inventor: GEISLER BERNHARD DR
IPC: B01J31/20
Filed: 1998-01-16
Abstract: Aldehydes are produced by hydroformylation of olefins using a dissolved homogeneous catalyst comprising a special Group VIII metal-polyamine complex, followed by distillation of products with removal of high-boiling components from the sump and recycling of catalyst and excess ligand. A process for the production of aldehydes or aldehydes and alcohols comprises the hydroformylation of olefins at 50-100 deg C and 20-1000 bar in presence of a homogeneous (dissolved) complex catalyst. This catalyst contains a Group VIII metal and a phosphorus-free, multi dentate ligand consisting of a derivatized, essentially water-insoluble polyamine with an average mol.wt of more than 1000 and at least 10 nitrogen atoms. After the reaction, the catalyst complex and excess ligand are returned to the hydroformylation reaction after complete or partial removal of aldehydes and alcohols by distillation, and at least part of the high-boiling component is continuously or at least intermittently removed from the distillation sump. An Independent claim is also included for a hydroformylation catalyst complex with a Group VIII metal as central atom and, as ligands, at least one carbonyl group and at least one polyamine as above.

Filed: 1998-11-06
Abstract: The invention relates to a method for adjusting the transmission ratio in a continuous variable transmission that is provided with a variator. According to the invention, a minimal pressure force p1,min and/or p2,min is continuously calculated for the two variator discs on the basis of the relevant transmission and the relevant torque to be transmitted in order to press the continuous variable element. The primary and secondary discs are determined as controlled variable to be used for the variator transmission according to the calculated minimal pressure force, whereby the controlled variable is determined by comparing the necessary pressure values p1,soll or p2,soll to the calculated minimal pressure force values in such a way that if p1,soll </= p1,min the controlled variable changes from the primary side to the secondary side and if the condition p2,soll </= p2,min is fulfilled, the secondary side changes to the primary side, whereby the primary side is the controlled variable at the beginning of the procedure.
