摘要： Disclosed is a method for manufacturing a horological component according to which a silicon-based piece having the desired shape of the horological component is produced and the piece is subjected to a thermal oxidation and deoxidation treatment to remove a predetermined thickness of silicon in order to increase the mechanical strength of the piece. This method is characterized in that the thermal oxidation and deoxidation treatment is carried out in several steps, each step including a thermal oxidation phase followed by a deoxidation phase.

摘要： A pivot mechanism for guiding in rotation comprises a mobile element connected to a fixed element through flexible connections; with the flexible elements being configured to guide the mobile element according to a rotational movement in a plane, around a pivoting axis perpendicular to the plane; with each of the flexible connections comprising an intermediary junction provided with an expansion slot, the expansion slot being configured to expand during the rotation of the mobile element, so that the mobile element can pivot according to a second angular amplitude that is greater than a first angular amplitude achieved without said expansion slot; with the intermediary junctions being connected to one another by a coupling member; each of the coupling members being configured so as to prevent a movement out of the plane and a lateral movement in the plane of the mobile element. The pivot mechanism has a very high rotational amplitude.

摘要： There is disclosed a timepiece resonator having an inertia element suspended from a flexible strip deformable in a plane XY parallel to a longitudinal direction Y, and whose transverse extension along a transverse axis X, in projection onto the plane XY, is variable and of positive value on at least one side of the neutral axis (FN) of said strip, which includes, at a distance from its embedments, at least one rib extending along an axis Z perpendicular to the plane XY, each having at least one generatrix which is farther from the neutral axis (FN) than the external surfaces of the sections of the strip located outside the ribs, and the longitudinal extension (LN) of each rib of the strip, along the longitudinal axis Y, is less than one fifth of the length L of the strip between its embedments.

摘要： A timepiece regulator includes a detached lever escapement mechanism, and a resonator with a quality factor Q including an inertia element comprising an impulse pin integral with an inertia element and cooperating with a fork of the lever. This inertia element is subjected to the action of elastic return means directly or indirectly fixed to the plate and is arranged to cooperate indirectly with an escape wheel set comprised in the escapement mechanism. This resonator mechanism is a resonator with a virtual pivot rotating about a main axis (DP), with a flexure bearing subjected to the return force of at least two flexible strips attached to the plate, defining together a virtual pivot with a main axis (DP), the lever pivoting about a secondary axis (DS).

摘要： The oscillator for a regulator of a timepiece mechanism comprises a frame, a rigid body and a mechanism) for connecting the rigid body to the frame enabling oscillations of the rigid body relative to the frame. The connecting mechanism comprises at least one first and one second rigid parts, and a first and a second flexible elements, in the form of angular sectors of rings. The first and second flexible elements extend mainly in separate non-parallel planes. The first and second flexible elements are concentric. The first and second flexible elements each connect the first and second rigid parts together.

摘要： A flexible guide assembly for a rotating resonator mechanism, the assembly including a fixed support and two flexible guides extending in substantially the same plane or in two different parallel planes, the first flexible guide including a first element movable with respect to the fixed support, a first pair of flexible strips connected to the first movable element, such that the first movable element can move by bending the strips of the first pair in a circular motion about a first centre of rotation, the second flexible guide includes a second element movable with respect to first movable element, a second pair of flexible strips connecting the second movable element to the first movable element, such that the second movable element can move with respect to the first movable element by bending the strips of the second pair in a circular motion about a second centre of rotation. The first centre of rotation and the second centre of rotation are offset by a first predefined distance belonging to a plane of the assembly.
