摘要： The method for manufacturing a timepiece component is capable of thermocompensating a functional assembly including the timepiece component. The method includes at least the following actions: a) providing (e1) a substrate (1) of semiconductor or metallic material; b) proceeding with the deposition (e2) of a polycrystalline or monocrystalline silicon layer (5) on the substrate (1); c) releasing (e4) the timepiece component (10) from the substrate (1).

摘要： A method for manufacturing at least a part of a timepiece is disclosed. The method comprises a first step of assembling flat layers together to from a substantially flat multilayer structure, Wherein at least a first layer of said layers is designed to form one flexible blade in the timepiece. Then, the multilayer structure is deployed in a direction substantially normal to the flat layers. Then at least one mass is fixed to the flexible blade, the mass being more rigid than the flexible blade.

摘要： A timepiece resonator mechanism includes a structure carrying, via a flexible suspension system, an anchor unit to which is suspended an inertia element oscillating about a pivot axis extending in a first direction Z, in a first rotational degree of freedom RZ, under the action of the return forces of a flexure pivot including longitudinal elastic strips each fixed to this inertia element and to this anchor unit. The flexible suspension system includes, between the anchor unit and a first intermediate mass directly or indirectly fixed to the structure, a transverse translation table with a flexure bearing and including transverse strips or transverse flexible shafts which are rectilinear and extend in this second direction X orthogonal to the first direction Z and symmetrically around a transverse axis crossing this pivot axis.

摘要： Isochronous pivot for a resonator including two flexible strips joining attachment points of a first and a second element, defining two strip directions, and a pivot axis, at the intersection of their projections or at their intersection, each strip having a free length between its attachment points, and an axial distance between the pivot axis and the attachment point thereof farthest from the axis, the attachment point ratio X=D/L being greater than one for each strip, the strip directions defining with the axis a first apex angle whose value in degrees is comprised between f1(X)=108+67/(10X−6), and f2(X)=113+67/(10X−6).

摘要： A flexible guide for a rotary resonator mechanism, in particular of a horological movement, the guide including a first support, an element movable relative to the first support, a first pair of flexible strips connecting the first support to the movable element, so that the movable element can displace relative to the first support by bending the strips in a circular movement about a centre of rotation, the flexible guide being arranged substantially in a plane, including a prestressing device, the prestressing device being configured to apply a force for buckling the flexible strips by bringing the first support closer to the movable element, so that the flexible guide includes two stable positions of the element movable relative to the first support for which the return moment is zero, the two stable positions having a predetermined angle of rotation therebetween.

摘要： The present invention relates to a wristwatch comprising a mechanical clock movement with a tuning fork resonator. The oscillator preferably comprises a material A with a low internal friction. In the oscillator of the invention, the unwanted symmetrical oscillations are avoided, for example, by the choice of the materials from which the tuning fork is manufactured. According to preferred embodiments, the rod and/or fastening of the oscillator comprises a material having greater internal friction than that of said material A, such that the quality factor Q2 of the symmetrical oscillations is reduced, in contrast to the quality factor Q1 of the anti symmetrical oscillation mode.

摘要： A method for maintaining and regulating frequency of a timepiece resonator mechanism around its natural frequency, the method including: at least one regulator device acting on the resonator mechanism with a periodic motion, to impose a periodic modulation of resonant frequency or quality factor or a position of a point of rest of the resonator mechanism, with a regulation frequency between 0.9 times and 1.1 times the value of an integer multiple of the natural frequency, the integer being greater than or equal to 2 and less than or equal to 10, and the periodic motion imposes a periodic modulation of the quality factor of the resonator mechanism, by acting on losses and/or damping and/or friction of the resonator mechanism.

摘要： A timepiece mechanism comprising a regulator, an energy distributing member a pallet fork controlled by the regulator to alternate in locking and releasing the energy distributing member, and a decoupling member elastically connected to the pallet fork and to the regulator. The decoupling member is arranged so as to oscillate between two stop elements.
