摘要： A crystal resonator comprises a first vibrating region provided on a crystal wafer, a second vibrating region provided on the crystal wafer, the second vibrating region having a different thickness and positive/negative orientation of the X-axis from those of the first vibrating region, and excitation electrodes which are provided respectively on the first vibrating region and the second vibrating region for causing the vibrating regions to vibrate independently. Frequencies that change by different amounts from each other relative to a temperature change can be retrieved from one vibrating region and the other vibrating region. Thus, based on an oscillating frequency of the vibrating region in which a clear frequency change occurs relative to the temperature, the oscillating frequency of the other vibrating region can be controlled. Thereby, increases in the complexity of the crystal oscillator can be suppressed.

摘要： Provided is a device capable of easily and accurately detecting a vibration period when, for example, an earthquake occurs. When a quartz-crystal plate bends upon application of a force, capacitance between a movable electrode provided at its tip portion and a fixed electrode provided on a vessel to face the movable electrode changes, so that an oscillation frequency of the quartz-crystal plate changes according to this capacitance. Therefore, when the vessel is vibrated, there appear a first state where the quartz-crystal plate ends to approach the fixed electrode and a second state where the quartz-crystal plate is in an original state or bends to be apart from the fixed electrode. Accordingly, an oscillation frequency corresponding to the first state and corresponding to the second state alternately appear, and therefore, it is possible to find the period (frequency) of the vibration.

摘要： In an external force detection apparatus, a crystal plate is cantilevered within a container. Excitation electrodes are formed on the top surface and the bottom surface of the crystal plate. A movable electrode is formed on a distal end on the bottom surface of the crystal plate and is connected to the excitation electrode on the bottom surface via an extraction electrode. A fixed electrode is provided on the bottom of the container to oppose the movable electrode. The excitation electrode on the top surface and the fixed electrode are connected to an oscillating circuit. When an external force acts on the crystal plate to bend it, the capacitance between the movable electrode and the fixed electrode changes, and this capacitance change is captured as a change in the oscillating frequency of the crystal plate.
