Abstract: A control lever for the pitch angle of a blade in a turbomachine, said lever having a first end intended to be mounted on a blade pivot so as to rotate it and a second end comprising a cylindrical peg for mounting on a control annulus, this peg being fixed by crimping of one of its ends in an orifice of the second end of the lever and comprising an annular flange to which is applied the second end of the lever, wherein stress distribution means are interposed between the second end of the lever and the crimped end of the peg.

Abstract: The invention relates to a compressor blade for a rotary disk of a turbine engine, the blade presenting orthogonal axes that are longitudinal, tangential, and radial, said blade extending radially between a root and a tip, and longitudinally between a leading edge and a trailing edge, said blade being for rotating inside an outer stator shroud having its surface covered in an abradable material. In the invention the tip of the blade presents at least one chamfer in order to reduce the area of contact that can exist between the tip of the blade and the abradable material.

Abstract: An epoxy resin composition for encapsulating semiconductors including (A) an epoxy resin, (B) a phenol resin, (C) an inorganic filler, (D) a curing promoter, and (E) a surface-treated coloring agent, wherein the coloring agent before the surface treatment is a carbon precursor with a carbon content of 90 wt % or more or carbon black having a DBP absorption of 100 cm 3/100 g or more, and a semiconductor device encapsulated with the epoxy resin composition. The epoxy resin composition can produce semiconductors which are free from electrical failures such as a short circuit, a leak current, and the like, do not induce wire deformation, and exhibits excellent laser marking characteristics.

Abstract: Control lever for the angular setting of a stator blade, comprising a first end intended to be fitted in a fixed manner on a blade pivot, a second end comprising a cylindrical pin for fitting on a control ring, and a flat intermediate part connecting the first and second ends having shapes and dimensions determined in order to increase the natural frequencies of the lever in flexion and in torsion above the vibratory frequencies of the turboshaft engine upstream of the lever and in order to retain the stiffness of the lever.
