摘要： A parallel link robot (10) provided with a base (11), a moving part (12), three links (20a to 20c) coupling the base and the moving part and having respectively single degrees of freedom with respect to the base, and three actuators (13a to 13c) respectively driving the links, each of the links comprised of a drive link (21a to 21c) coupled with the base and two driven links (22a to 22c, 23a to 23c) coupling the drive link and the moving part and parallel to each other, and further provided with a posture changing mechanism (15) which changes a posture of an element (19) attached to the moving part, an additional actuator (13d to 13f) arranged between the two driven links of at least one link in parallel to these driven links, and a power transmission shaft (39) which extends coaxially from the additional actuator and transmits rotational drive force to the posture changing mechanism. Due to this, it is possible to increase the degrees of freedom without reducing the possible region of operation and the acceleration/deceleration performance.

摘要： A piezoelectric power generator that includes a support body, a piezoelectric element, and a bias compressive stress applying member. The piezoelectric element is placed on the support body. The piezoelectric element has a piezoelectric plate that is polarized in the thickness direction, and first and second electrodes that are each provided on a surface of the piezoelectric plate. The bias compressive stress applying member is supported on the side above the piezoelectric element by the support body. The bias compressive stress applying member applies to the piezoelectric element a bias compressive stress acting in the thickness direction of the piezoelectric plate, so that the magnitude of a compressive stress in the piezoelectric plate changes with a change in externally applied stress.

摘要： A vibrator includes a vibrating body having a substantially quadrangular prism shape and including four side surfaces extending in the longitudinal direction of the vibrating body. A common electrode is formed on substantially an entire surface of one of the side surfaces of the vibrating body. Split electrodes extend in the longitudinal direction on another side surface opposite to the side surface on which the common electrode is formed, and are spaced from each other in the width direction of the side surface on which the split electrodes are formed. In the vibrating body, a first polarized section is polarized in a direction from the side surfaces of the vibrating body that do not have an electrode disposed thereon, toward the split electrodes. A second polarized section is polarized in a direction from the side surfaces of the vibrating body that do not have an electrode disposed thereon, toward the common electrode. Thus, the vibrator does not include a joint layer, and is polarized in opposite directions in the thickness direction.

摘要： The present invention provides a piezoelectric vibrator, in which there is no significant change in the characteristics even when depole occurs due to heat shock and the like. The piezoelectric vibrator includes a first piezoelectric substrate having split electrodes formed on one main surface thereof and a second piezoelectric substrate having a common electrode formed on one main surface thereof. The remaining main surfaces of both piezoelectric substrates are bonded to each other via an intermediate electrode. The material of the first piezoelectric substrate differs from the material of the second piezoelectric substrate. As a result, the difference (longitudinal DF) between a resonant frequency and an anti-resonant frequency in a longitudinal vibration of the piezoelectric vibrator substantially coincides with the difference (transverse DF) between a resonant frequency and an anti-resonant frequency in a transverse vibration thereof.

摘要： A method of detecting an angular velocity including generating a differential signal from a vibrator, the differential signal having a Coriolis force proportional to angular velocity if the vibrator is rotated; generating a timing signal based on the differential signal; and applying the differential signal to a voltage-time converter which, based on the timing signal, converts the differential signal to a pulse train having a duty cycle proportional to the angular velocity. The method is implemented in an angular velocity detector, such as a gyroscope.
