摘要： Protrusions made of an electrically conductive material such as a metal or ceramic are formed around a node point or a node line of vibrations of a piezoelectric plate on two principal planes thereof by a spraying process. The piezoelectric plate is held at the protrusions with leaf springs on the two principal planes. Thus, protrusions of a small surface area are formed without deteriorating the piezoelectric plate. The piezoelectric plate can be held stably without deteriorating the vibration characteristics. An alternating voltage is applied to electrodes of the piezoelectric plate through the electrically conductive protrusions. Because a spraying process is used, the protrusions can be thickly and precisely formed in a small area and held surely and reliably, with a good mechanical strength of the protrusions.

摘要： A thin film micromechanical resonator (resonator) having improved drive efficiency, a resonator gyro having improved sensitivity in detecting an angular velocity, and a navigation system and an automobile using the resonator gyro. The resonator includes a tuning fork structure made of a non-piezoelectric material, and a first electrode and a second electrode disposed respectively at the inner side and the outer side of the tuning fork arm. On the first and second electrodes, a first piezo film and a second piezo film are provided respectively, and a third electrode and a fourth are respectively provided electrode thereon. When an alternating voltage is applied to the third and fourth electrodes at the opposite phases each other, the tuning fork resonates in the direction perpendicular to the center line. The resonator gyro detects, at the sensing section which is formed of another electrodes and another piezo film, the Coriolis force generated in proportion to angular velocity given to the resonator.

摘要： An electronic circuit is manufactured by the following method. Elements are formed on a front surface of a substrate, and then, a recess is formed around each of the elements in the front surface of the substrate. Then, a portion of the substrate is removed from a back surface of the substrate until reaching the bottom of the recess. In the method, the elements are separated at once by removing the portion of the substrate from the back surface, and thus, the elements are manufactured efficiently.
