| 20130241363 | METHOD OF MANUFACTURING RESONATOR ELEMENT, METHOD OF MANUFACTURING RESONATOR, RESONATOR, OSCILLATOR, AND ELECTRONIC APPARATUS - A method of manufacturing a resonator element includes a process of forming a mesa substrate by disposing a first mask on a principal surface located on a +Y′-axis side of the quartz crystal substrate, disposing a second mask on a principal surface located on a −Y′-axis side so as to be located at a position shifted toward a +Z′-axis side from the first mask, and etching the quartz crystal substrate via the first and second masks, the mesa substrate including a vibrating section including a first protruding section protruding toward the +Y′-axis side from the quartz crystal substrate and a second protruding section protruding toward the −Y′-axis side, and a small-thickness section disposed along an outer edge of the vibrating section and having a thickness smaller than a thickness of the vibrating section. | 09-19-2013 |
| 20130307377 | PIEZOELECTRIC RESONATOR HAVING MESA TYPE PIEZOELECTRIC VIBRATING ELEMENT - A vibrating element includes: an element plate that has a vibrating portion that performs thickness-shear vibration, a peripheral portion that is integrally formed with the vibrating portion, and a protruding portion that is provided at the peripheral portion; and an excitation electrode that is provided at the vibrating portion. When a side length of the vibrating portion is Mx, when a side length of the excitation electrode is Ex, and when a wavelength of flexure vibrations of the element plate is λ, the relationship of (Mx−Ex)/2=λ/2, and Mx/2={(A/2)+(¼)}λ (where, A is a positive integer) is satisfied, and when a length of the protruding portion is Dx, and when a distance between the vibrating portion and the protruding portion is Sx, the relationship of Dx=λ/2)×m, and (λ/2)×n−0.1λ≦Sx≦(λ/2)×n+0.1λ (where m and n are positive integers) is satisfied. | 11-21-2013 |
| 20140354116 | COST-EFFECTIVE SINGLE CRYSTAL MULTI-STAKE ACTUATOR AND METHOD OF MANUFACTURE - This invention pertains to piezoelectric actuators made of single crystal active elements which not only exhibit uniform and superior displacement in the axial direction but also of lower cost to produce than full single crystal ring or tube actuators. Said multi-stake actuator is made up of multiple longitudinal (d33) or transverse (d3i or d32) mode piezoelectric single crystal active elements, bonded together by epoxy with the aid of shaped edge- and top and bottom washer-stiffeners which are configured to suit various application needs. | 12-04-2014 |
