摘要： A piezoelectric frame includes a tuning-fork type piezoelectric vibrating piece having excitation electrodes on each of at least two vibrating arms extending in a first direction from one end of a base portion thereof. Respective supporting arms extend in a first direction from respective external edges of the vibrating arms. An outer frame portion surrounds the tuning-fork type piezoelectric vibrating piece. The connecting portions have designated widths and connect the respective supporting arms to the outer frame portion. During manufacture, the designated widths are trimmed (e.g., by a pulsed laser) until the desired vibration frequency is obtained.

摘要： The present invention provides an angular velocity sensor and a method of fabrication thereof that facilitates the work of affixing a tuning-fork-type crystal element and adjusting the same, preventing waste caused by scrapping defective products and also encouraging miniaturization of components. The angular velocity sensor comprises: a tuning-fork-type crystal element which is provided with a drive electrode for exciting the vibration of the tuning fork and a sensor electrode for detecting an electrical charge that is generated in response to an angular velocity that is being detected; an independent pedestal to which a main surface of a tuning-fork base portion of the tuning-fork-type crystal element is previously affixed to form an integrated unit; a main package for surface mounting, in which the tuning-fork-type crystal element is hermetically sealed and which has a cavity with an inner base surface to which the pedestal integrated with the tuning-fork-type crystal element is affixed; and an IC having an oscillation circuit for driving the tuning-fork-type crystal element and a signal processing circuit for creating a signal in correspondence to the angular velocity corresponding to the electrical charge, and which is also disposed either inside or outside the package. The pedestal has a weight and/or shape that ensures that the center of gravity of the tuning-fork-type crystal element that is integrated therewith moves towards the tuning-fork base portion side, maintaining the horizontal alignment of the tuning-fork-type crystal element.

摘要： Methods are disclosed for manufacturing piezoelectric devices. In an exemplary method, a base wafer is prepared that defines an array of multiple bases. Between each base on the wafer is a through-hole defined in respective parts by the respective edge surfaces of adjacent bases. A piezoelectric wafer is prepared that defines an array of multiple piezoelectric frames each having a piezoelectric vibrating piece and a surrounding frame portion. The vibrating piece includes an excitation electrode and extraction electrode. The extraction electrode extends to the through-hole. An adhesive is applied to a surface of the frame portion including a surface of the extraction electrode. The adhesive bonds the piezoelectric wafer to the base wafer. Excess adhesive is removed from the through-hole to expose a portion of the extraction electrode in the through-hole. An external electrode is formed on the outer surface of the base and extends to the through-hole in which the external electrode covers the edge surface of the through-hole, an edge surface of the adhesive, and the exposed portion of the extraction electrode.
