Abstract: L'outillage (20) est destiné à former un article (66) possédant un cadre périphérique (52) moulé par injection et définissant une ouverture fermée par une feuille mince rapportée (48, 140). Ladite feuille est forgée dans un matériau en feuille (40) et, conjointement avec un poinçon associé (36), coopère avec un moule composite (24, 26) pour définir complètement une empreinte (30) en vue du moulage par injection de l'article. La feuille mince rapportée forme une partie des parois de l'empreinte (30) et est automatiquement thermosoudée au cadre lors de l'opération de moulage. La feuille mince rapportée peut être pelée sur le cadre à l'aide d'une languette d'arrachement (76, 142). La languette d'arrachement (76) peut être formée par le poinçon (36). La languette d'arrachement (142) peut être formée séparément à l'extérieur du moule dans le matériau en feuille, puis pliée et recourbée, après quoi la feuille mince rapportée (140) est découpée dans le matériau en feuille de sorte que la languette d'arrachement soit simultanément coupée à sa forme préférée.

Title: Electrically conductive compositions and methods for the preparation and use thereof
Inventor: CAPOTE MIGUEL ALBERT
IPC: H05K3/46
Filed: 1992-10-01
Granted: 2004-09-14
Abstract: Electrically conductive adhesive compositions and methods for the preparation and use thereof; in which a solder powder, a chemically protected cross-linking agent-with fluxing properties and a reactive monomer or polymer sue the principal components. Depending upon the intended end use; the compositions comprise three or more of the following: a relatively high melting metal powder; solder powder; the active cross-linking agent which also serves as a fluxing agent; a resin; and a reactive monomer or polymer. The compositions are useful as improved conductive adhesives, such as for attaching electrical components to electrical circuits; the compositions comprising metal powder are ideally suited for creating the conductive paths on printed circuits. The compositions for forming conductive-paths may first be applied to a substrate in the desired pattern of an electrical circuit, and then heated to cure it. During heating, the action of the cross-linking agent and optional reactive monomer or polymer within the mixture fluxes the metals, enabling sintering to occur between the metal powder and the solder powder.

Abstract: In an acceleration detector fox detecting three-dimensional components of acceleration applied thereto independently with respect to three axes X, Y and Z of an orthogonal coordinate system, a plurality of resistance elements having a piezo resistance effect are formed in a thin-sheet resilient member with an unique arrangement thereof fox improving the sensitivity of the detector. Electric resistance of the resistance elements is varied in response to strain of the resistance elements accompanied with an elastic deformation of the resilient member. The resilient member is fixed at its periphery on a frame of the detector. A weight is connected with a center portion of the resilient member such that the elastic deformation is caused when the weight is displaced by receiving acceleration. When the X- and Y-axes is defined on the resilient member, all of resistance elements for detecting the components of acceleration with respect to the X- and Y-axes are limited within an inner area adjacent to a circumference of the center portion. The inner area is capable of causing a larger elastic deformation than an outer area adjacent to the frame when the weight is displaced by receiving the acceleration. Therefore, an improved sensitivity of the detector is accomplished by the arrangement of the resistance elements.

A slidable second cylindrical tubular member reciprocates within the first tubular member along the axis thereof and is provided with a gasket at the top thereof in sealing contact with the inner surface of the first tubular member. A permanent filter is provided at the top of the second cylindrical tubular member. A fixed piston head is located within the second cylindrical tubular member and is fixed relative to the first tubular member.

Abstract: A storage and retrieval crane system that includes a tower having a pair of spaced columns and a tower drive mechanism for moving the tower horizontally along a floor between storage racks. A carriage is coupled to a carriage drive mechanism for vertical movement between the columns, and a shuttle is coupled to a shuttle drive mechanism on the carriage for moving the shuttle horizontally from the carriage in directions lateral to direction of movement of the tower along the floor. At least one of the drive mechanisms, and preferably all of the drive mechanisms, include primary and secondary drive arrangements, and facility for selectively alternately connecting one or the other of the primary and secondary drive arrangements to drive the tower, carriage or shuttle. Thus, in the preferred embodiment of the invention, each of the drive mechanisms is fully redundant, so that machine drive may be switched from primary to secondary mechanisms in the event of failure without significant down-time or loss of production.

Title: Optical pulse sequence generator
Inventor: LUCEK JULIAN KAZIMIERZ
IPC: H04J14/08
Filed: 1994-10-11
Granted: 2000-03-28
Abstract: An optical pulse sequence is generated by applying a repetitive optical signal to an optical modulator connected in the laser cavity of a mode-locked laser. The pulse sequence in the laser cavity is then ouput. The repeat period of the repetitive optical signal is set to be equal to, or an integer multiple of, the cavity round-trip time. The laser is thereby driven to output pulses in bit positions corresponding to the non-zero pulses of the input repetitive optical signal. In one example, he output pulse sequence is used to control an optical switch to provide an OTDM programmable multiplexer using optical signals.

Abstract: Sont décrit un système et un procédé perfectionnés pour transmettre des informations par des voies de transmission en phase (I) et en quadrature (Q) dans un système de transmission à spectre étalé. Dans un exemple de mode de réalisation, des premier et deuxième signaux d'information (a¿n?, b¿n?) sont transmis respectivement sur les voies de transmission en phase et en quadrature à l'aide de signaux de transmission à spectre étalé à séquences directes. Des signaux de bruit pseudo-aléatoire en phase (PN¿I?) et de bruit pseudo-aléatoire en quadrature (PN¿Q?), ayant des codes PN prédéterminés (178, 180), sont utilisés respectivement pour étaler le spectre des premier et deuxième signaux d'information (a¿n?, b¿n?). En particulier, les signaux PN¿I? et PN¿Q? sont respectivement combinés avec les premier et deuxième signaux d'information (a¿n?, b¿n?) et un signal de fonction orthogonale (174) pour donner des signaux de modulation de la voie I et de la voie Q (S¿I?, S¿Q?). Ces derniers sont utilisés pour moduler des signaux multiplex en phase (I) et en quadrature (Q) en vue de leur transmission à un récepteur par l'intermédiaire de voies de transmission I et Q, respectivement. Dans un mode préféré de réalisation, le récepteur agit pour produire une estimation d'au moins le premier signal d'information sur la base des signaux multiplex (R¿I?), R¿Q?) modulés sur la voie I et la voie Q et reçus sur les voies de transmission I et Q. Ces signaux multiplex (R¿I?, R¿Q?) modulés reçus sont démodulés et leur spectre est désétalé, les séquences résultantes étant corrélées pour donner des signaux de projection en phase (I) et en quadrature (Q). Un déphaseur sert à fournir une estimation d'au moins le premier signal d'information sur la base de signaux de projection I et Q et d'un signal pilote reçu.

Abstract: Method and apparatus for simplified heat-treatment to harden aluminum castings made from heat-treatable aluminum alloys, especially with a copper content of up to 5%, such as the 300-T6 series, for example those cast aluminum parts utilized in the manufacture of automobile motors: cylinder heads, engine blocks and the like; whereby the castings are directly quenched before cooling below 400°C (and preferably immediately after demolding) without undergoing the conventional steps of natural cooling followed by a re-heating "solution"  heat treatment (typically of at least 470°C for at least two hours, or for a shorter time at higher temperatures) which "solution" heat treatment requires excessive and expensive equipment, energy, and production time. This invention also has the unexpected beneficial effect of avoiding development of silicon spheroidization in the alloy matrix thereby resulting in improved machining properties.
