Abstract: A balance spring with two pairs each formed of adjacent coils respectively including a stopping device and a complementary stopping device defining together, for each pair, a respective, relative, maximum angular travel of the coils during the local coupling thereof. The stopping device and the complementary stopping device define different maximum angular travel values, to gradually limit the amplitude of pivoting between the ends of the balance spring during accelerations greater than desired values, one of the pairs cooperating in abutment before the other, to gradually modify the resulting rigidity of the balance spring by the successive deactivation or reactivation of the coils thereof.

Abstract: A component intended to be in friction contact with another component, the component being coated with an electrically conductive layer in one piece, at least partially covering every surface of the component, the friction occurring on at least one of these surfaces, called the functional surface, the functional surface being surrounded by a plurality of side surfaces, the component having on its functional surface a texture formed of a succession of troughs coated with the electrically conductive layer, the troughs each extending between two side surfaces such that the electrically conductive layer remains in one piece over the component despite the wear caused by friction on the functional surface. The invention also relates to the method for manufacturing the component by the DRIE (deep reactive ion etching) process, wherein surface defects on the sides machined by the DRIE process are used to form the troughs.

Abstract: A system including two components intended to be in friction contact with each other in a given direction, wherein the friction occurs in a functional area, wherein the system is at least one of the two components including, on a surface in the functional area, a texture formed of a series of troughs of rounded shape separated by peaks or a series of bumps of rounded shape separated by troughs, the troughs extending parallel in the given direction and allowing for the evacuation of debris produced by friction and serving as a reservoir for a lubricant. A method for manufacturing at least one component or a mold by the DRIE (deep reactive ion etching) process, wherein surface defects on the sidewalls machined by the DRIE process are used to form the troughs.
