摘要： The present invention is directed to a tuning fork wherein a damping piece is provided, either integral with said tuning fork vibrator or a separate piece attached thereto, and wherein a damper member is intersected between said damping piece and a housing for accommodating the tuning fork vibrator.Since the (1/2)f.sub.O spurious response which is caused in the tuning fork vibrator to be spread within the damping piece is adapted to be absorbed by the damper member, the tuning fork is made smaller in shape.

摘要： An AT-cut piezoelectric crystal resonator having a plurality of contoured surfaces, two of these contoured surfaces being generated by translating contour lines parallel to the z-axis and perpendicular to the electric axis. At least one of these two surfaces is convex, and another two contoured surfaces are perpendicular to the z-axis and spaced apart by a length dimension z'.sub.0 which is 0.1 to 1.3 of the maximum thickness dimension representing the distance between the first mentioned two surfaces and measured along a line perpendicular to the x-axis. The resonator is adapted for performing a mode of vibration along the thickness forming either a fundamental standing wave or an overtone thereof of a thickness-shear vibration. The free ends of the vibration are positioned at the first mentioned two surfaces, and the amplitude of vibratory displacements appearing along the x-axis is maximum at the center of each surface of the first mentioned two surfaces. The last mentioned center is the midpoint of a length taken along the x-axis dimension which is 3 to 15 of the maximum thickness dimension, and constituting the span of arc of the convex surface. The amplitude becomes null at a point on each of the first mentioned two surfaces where that point approaches each end of the convex line generating the convex surface, and the distribution of the amplitude is uniform on any point taken along the length of the above mentioned z-axis dimension on each of the first mentioned two surfaces.

摘要： Piezoelectric microresonators with suspension arms, oscillating according to a vibration resulting from the superposition of a principal extensional mode of oscillation, of a first shear coupled mode of oscillation and of a second extensional coupled mode of oscillation. The suspension arms are attached to the active part of the resonator in a place which is the intersection of a nodal plane of the vibration resulting of the superposition of the principal mode and of the first coupled mode of oscillation. The other end of the arms is fixed on a stiff support in a location which coincide with a node of their vibration.

摘要： A mechanical vibrator for a timepiece in which a ceramic supporting substrate is rigidly secured to an inner wall of an evacuated housing. The supporting substrate is formed at its one surface with a pair of conducting metal layers serving as leads and at its other surface with a conducting metal layer over a substantially large area. A piezoelectric vibrating element having exciting electrodes is placed on the ceramic supporting substrate and rigidly connected thereto such that the electrodes of the piezoelectric vibrating element are electrically connected to the conducting metal layers formed on the one surface of the ceramic supporting substrate. The conducting metal layers are in turn connected to projecting leads extending outwardly of the evacuated housing and adapted to be connected to a printed circuit of the timepiece.
