Abstract: An adjusting mechanism is provided for a basket used in a portion of a seat to adjust the shape of the seat. The mechanism includes a handle that is rotatably engaged to a shaft. The shaft is slidably engaged within a bore in a gear that is part of a gear mechanism. The gear mechanism is connected to a first end of the basket and a link is connected from the gear mechanism to a second end of the basket. The bore has a complementary cross sectional profile to the shaft to permit rotation thereby. The shaft is slidable along the axis of the bore to permit changes in the relative position between the handle and the gear mechanism.

Abstract: A semiconductor device having a reflecting layer consisting of unit semiconductors each consisting of two or more semiconductor films of different compositions. The thickness of the unit semiconductors varies continuously or in steps in the direction of thickness of the reflecting layer, preferably decreases in the direction toward the light incidence surface of the layer. For example, the reflecting layer has a varying-thickness portion whose unit semiconductors have a continuously varying thickness, and may include an iso-thickness portion whose semiconductors have the same thickness. The composition at the interface of the adjacent films preferably changes to mitigate a lattice mismatch which causes crystal defects of the layer.

Abstract: Méthode pour déformer de façon graduelle, en totalité ou localement un modèle stochastique de type gaussien ou apparenté d'un milieu hétérogène tel qu'une zone souterraine, contraint par un ensemble de paramètres relatifs à la structure du milieu. - La méthode comporte le tirage d'un nombre p au moins égal à deux, de réalisations indépendantes d'une partie au moins du modèle choisi du milieu, parmi toutes les réalisations possibles et une combinaison linéaire de ces p réalisations avec p coefficients tels que la somme de leurs carrés est égale à 1. Cette combinaison linéaire constitue une nouvelle réalisation du modèle stochastique et elle se déforme graduellement lorsque l'on modifie graduellement les p coefficients. La méthode peut comporter plus généralement plusieurs étapes itératives de déformation graduelle, avec combinaison à chaque étape d'une réalisation composite obtenue à l'étape précédente avec q nouvelles réalisations indépendantes tirées de l'ensemble des réalisations. La méthode donne la possibilité de déformer graduellement des réalisations d'un modèle représentatif du milieu tout en modifiant les paramètres statistiques relatifs à la structure du milieu. La méthode permet aussi des déformations graduelles individuelles de différentes parties du modèle tout en préservant la continuité entre ces parties. - Application à la construction de modèles stochastiques de réservoirs contraints à des données non linéaires (données liées à l'écoulement des fluides).</SDO AB>

Title: Hydrocarbon upgrading process
Inventor: TEITMAN GERALD JOSEPH
IPC: C10G65/04
Filed: 1998-05-12
Granted: 2008-04-01
Abstract: Low sulfur gasoline is produced from an olefinic, cracked, sulfur-containing naphtha by treatment over an acidic catalyst, preferably in intermediate pore size zeolite such as ZSM-5 to crack low octane paraffins and olefins under relatively mild conditions, with limited iromatization of olefins and naphthenes. This is followed by hydrodesulfurization over a hydrotreating catalyst such as CoMo on alumina.  The initial treatment over the acidic catalyst removes the olefins which would otherwise be saturated in the hydrodesulfurization, consuming hydrogen and lowering product octane, and converts them to compounds which make a positive contribution to octane. Overall liquid yield is high, typically at least 90 % or higher. Product aromatics are typically increased by no more than 25 wt.% relative to the feed and may be lower than the feed.

Abstract: A shaft seal having a high abrasion resistance is disclosed, by which the leakage of the gas from the high-pressure side to the low-pressure side can be reduced. In the shaft seal, flexible leafs are multi-layered to form a ring shape. The shaft seal is mainly arranged around the rotation shaft of a gas turbine or the like. The relevant turbine comprises a casing, a compressor, a rotation shaft, moving blades attached to the rotation shaft, and stationary blades attached to the casing in a manner such that the stationary blades face the moving blades, wherein the shaft seals are provided between a plurality of stationary blades and the rotation shaft wherein the leaves of each shaft seal contact the rotation shaft. Under the rated operating conditions, the top ends of the leaves slightly separate from the surface of the rotation shaft due to the dynamic pressure generated by the rotation of the rotation shaft. When the turbine is not operated, the top ends of the leaves contact the rotation shaft again due to the elastic restoring force of the leaves.

Abstract: A vertical cavity surface emitting laser, VCSEL, (2) with variable tuning layer (10) for adjusting the slope of the laser (2) and method for manufacturing the same are disclosed.      In practice, a VCSEL wafer is grown by any conventional technique, and fabricated into discrete lasers (2) while maintained in wafer form. The initial lasers (2) are then tested to determine characteristics, such as the slope efficiency distribution to within a target specification by altering the phase of the top facet reflectivity of the initial lasers (2).      The resulting change in transmission directly changes the laser slope in a predictable fashion.      The tuning step may be repeated, if necessary, to further refine. the slope to the desired value. The method produces VCSELs (2) with similar or consistent slopes from a plurality of wafers. Also disclosed are an optical subassembly (110) and optical transceiver (130) incorporating the improved VCSELs.
