    摘要: One inertial sensor detects an acceleration in a driving direction as well as an angular rate about one axis and an acceleration in a detecting direction at the same time. A driving-direction acceleration detecting unit is provided to members vibrating in mass members on the left and right via an elastic body. In this manner, when an acceleration is applied in the driving direction, the mass members on the left and right normally vibrated with a same amplitude and in opposite phases have displacement amounts in a same phase, and the driving-direction acceleration detecting unit detects the displacement amounts in the same phase as a capacitance change, thereby detecting the acceleration in the driving direction.

    摘要: This invention is directed to provision of high-performance inertial sensor that can sustain SNR even in an environment where vibration disturbance exists. A vibration type inertial sensor comprises: two deadweights (2, 3); means (C1, C2, C3, C4, +vd, −vd) for displacing the two dead weights in the anti-phase; two sets of electrodes (C5, C6, C7, C8) for detecting, as capacitance changes, the displacements of the two dead weights; and a C/V converting unit (53) for converting the capacitance changes of the electrodes to electric signals. In the vibration type inertial sensor, a set of electrodes (e.g., C5 and C8), which exhibit an increased electrostatic capacitance therebetween in the case where the two dead weights (2, 3) are displaced in the anti-phase, are electrically connected to each other, and a set of electrodes (e.g., C6 and C7), which exhibit a reduced electrostatic capacitance therebetween in the foregoing case, are electrically connected to each other, and further these sets of electrodes are connected to the C/V converting unit (53).

    摘要: Reliability and accuracy of a sensor are secured while adjustment cost of a sensor module is suppressed. A signal component analysis part 10 receives a signal output from a signal processing part 7 before passing through a low-pass filter 8, analyzes whether or not application of a fragile frequency with respect to a physical quantity is equal to or more than a threshold level, if the application of the fragile frequency is equal to or more than the threshold level, outputs output stop signals to output signal control parts 9, 16. The output signal control parts 9, 16 receive control signals output from the signal component analysis part 10, and outputs an acceleration signal and a physical quantity signal from which noise has been removed by the low-pass filters 8, 15 through the signal processing parts 7, 14.

    摘要: A high-performance angular rate detecting device is provided. A driving part including a drive frame and a Coriolis frame is levitated by at least two fixing beams which share a fixed end and are extending in a direction orthogonal to a driving direction, thereby vibrating the driving part. Even when a substrate is deformed by mounting or heat fluctuation, internal stress generated to the fixed beam and a supporting beam is small, thereby maintaining a vibrating state such as resonance frequency and vibration amplitude constant. Therefore, a high-performance angular rate detecting device which is robust to changes in mounting environment can be obtained.
