Turbomachine, comprising at least one thrust reverser and means for actuating this thrust reverser which comprise at least one hydraulic engine supplied with pressurised fluid by a fuel circuit of the turbomachine.

A propulsion system for an airplane having an integrated pylon includes a bypass turbojet and a nacelle. The nacelle has a downstream cylindrical part which is rigid and is attached at its upstream end to an intermediate case of the engine. This downstream cylindrical part also includes a longitudinal beam for attaching rods to secure the engine to the airplane.

A control panel including a cover which is provided with at least one tactile pressure detection zone forming a control button, in which a force sensor is arranged between the cover and a support, behind the detection zone, in which a spacer made of elastically compressible material is mounted between the force sensor and the cover so as to take up the mechanical plays between the force sensor and the cover, characterized by the fact that the spacer is at least partially translucent and by the fact that the control panel includes at least one main light source and a light collector which permits injection of the light produced by the said main light source into the thickness of the spacer so that the spacer produces a backlighting beam directed towards a zone to be illuminated of the detection zone.

A vibration damping device for a motor vehicle, features a first movable element (13, 14) and a second movable element (15, 16) both rotatable around an axis X, at least one group of elastic members (25, 26) mounted between the first movable element and the second movable element and acting against rotation of the first movable element and second element with respect to one another, and a phasing member (32, 33) rotationally movable around the axis X. The first movable element (13, 14) and the second movable element (15, 16) are coaxial and capable of transmitting a torque. The phasing member (32, 33) includes a first portion (32) and a second portion (33), for arranging the elastic members of the at least one group in series so that the elastic members of each group deform in phase with one another.

The system is based on placing on the façade a suitably anchored metal structure to which is fixed a plastic panel supporting geomesh layers that constitute support for the plants. At the top of these geomesh layers drip irrigation nozzles are arranged, supplied by a water recirculation pipe, and excess water is collected in a channel, which is then filtered, analysed, supplemented with fertilizer and acids, all under computer control. There is also the option to empty the recirculation circuit and add new water treated by reverse osmosis from a tank.

A vibration damping device (330) for a motor vehicle, having:a first element (13, 14) and a second element (15, 16) that are rotationally movable around an axis X and capable of transmitting a torque;at least one group of elastic members (25, 26) mounted between the first element and the second element and acting against rotation of the first element and second element with respect to one another;a phasing member (32, 33), rotationally movable around the axis X and constituted by a first portion (32) and a second portion (33), for arranging the elastic members of that group in series so that the elastic members of each group deform in phase with one another.

A simple, effective and economical method to improved the yield of CMOS devices using contact etching stopper liner, including, single neutral stressed liner, single stressed liner and dual stress liner (DSL), technology is provided. In order to improve the chip yield, the present invention provides a method in which a sputter etching process is employed to smooth / flatten (i.e., thin) the top surface of the contact etch stopper liners. When DSL technology is used, the inventive sputter etching process is used to reduce the complexity caused by DSL boundaries to smooth / flatten top surface of the DSL, which results in significant yield increase. The present invention also provides a semiconductor structure including at least one etched liner.

Fan (16), in particular for an aircraft cooling unit, having a wheel (128) comprising a hub (138) and an annular array of blades (140), a shaft assembly (136) for driving the wheel about an axis (A), and fusible means for connecting the hub of the wheel to the shaft assembly, said fusible connecting means comprising a first mounting sleeve through which the shaft assembly extends and which is surrounded by the hub, and fusible safety elements (174) which extend parallel to the axis (A) and are configured to break and to disengage the wheel from the shaft assembly when said wheel rotates and a driving torque of the wheel transmitted by the shaft assembly exceeds a certain threshold, characterised in that the connecting means comprise a second wearing sleeve (143) which is inserted between the first sleeve and the hub and through which the fusible elements extend, the second sleeve being made of a material which is different from that of the first sleeve and subject to wear by friction and / or by heating if the shaft assembly continues to rotate following the aforementioned disengagement.

A clutch release bearing (17), in particular for a motor vehicle, having: a tubular body (30) through which at least one input shaft (11) of a gearbox is intended to pass; at least one actuator having a part, movable in translation along the axis (X) of the body (30), intended for actuation of a clutch diaphragm; a target (28a, 28b) whose position is representative of the position of the movable part of the actuator; and a detector (29a, 29b) capable of detecting the position of the target (28a, 28b). The target (28a, 28b) is offset angularly from the detector (29a, 29b) with respect to the axis (X) of the body (30).
