摘要： In the present invention, a lens driving device has appropriate offset for miniaturization, excellent linearity of driving current versus displacement, and good displacement sensitivity. A casing holding a yoke with at least one permanent magnet mounted on an inner circumference thereof is connected with a lens holder having a driving coil installed on an outer sidewall thereof between an upper spring member and a lower spring member. When the driving coil is not powered, the lens holder props against the casing at a side opposite to an imaged object. When the lens holder props against the casing, the position of the driving coil along Z axis causing a magnitude of driving magnetic field intersecting with the driving coil is 50%˜90% of a maximum value of the driving magnetic field intersecting with the driving coil while the lens holder moves toward the imaged object.

摘要： A vibration control apparatus that can impart stabilized self-induced vibration without amplitude changes even under changes in ambient temperature is disclosed. When the apparatus is used with a vibrating gyroscope, detection accuracy is increased without temperature dependence of detection sensitivity on input angular velocity. The vibration control apparatus imparts self-induced vibration to a vibrator which has a pair of piezo-electric elements on the side surface of a vibration member having a resonance point. The vibrator is given self-induced vibration while the combined current value of the respective currents flowing through the pair of piezo-electric elements is held fixed. A drive signal output circuit outputs a drive signal applied to the pair of piezoelectric elements and has a voltage gain with a temperature dependence corresponding to the temperature dependencies of the equivalent resistances of the vibrator. The automatic gain control circuit holds the combined current value of the currents flowing through the pair of piezo-electric elements fixed. The drive signal output circuit may have a voltage gain contrary to the temperature dependencies of equivalent resistances of the vibrator.

The pickup member includes a layer of piezoelectric material polarized in the direction of the Z-axis and at least one pair of electrodes disposed on surfaces of the support member which are in parallel to the Z-axis. At least one of the electrodes is positioned to one side of a center line on its respective surface, the center line being parallel to the Z-axis. In one embodiment, the pickup member itself constitutes the support member of the tuning fork. In another embodiment, the pickup member is a separate unit which is affixed to a surface of the support member of the tuning fork.

摘要： An angular velocity detection circuit is capable of detecting angular velocity at good efficiency, while also being capable of suppressing the formation of offset to very low amounts even when differences arise in the equivalent resistances of a piezo-electric pair. The vibrator has at least one pair of piezo-electric elements on the side surface of a vibration member having a resonance point. A detection circuit detects differences in the currents flowing through the piezo-electric elements under the resonance state of the vibrator. A sample and hold circuit samples and holds the output of the detection circuit at a time where the displacement velocity of the vibrator becomes zero. The angular velocity is detected based on the output of this sample hold circuit.
