摘要： A small-sized, low-profile fluid pump having high pumping capabilities includes an actuator and a planar section including a metal plate. The actuator includes a disk-shaped piezoelectric element attached to a disk-shaped diaphragm. As a result of application of a square-wave or sine-wave drive voltage, the actuator performs a bending vibration from the central portion to the peripheral portion. The peripheral portion of the actuator is not restrained. The actuator performs a bending vibration in the state in which it is in proximity to the planar section while facing the planar section. A center vent is provided at or in an area adjacent to the center of an actuator facing area of the planar section that faces the actuator.

摘要： A piezoelectric micropump in which a pump chamber is isolated by a diaphragm. A piezoelectric element is disposed on a back surface of the diaphragm, and the diaphragm is deformed by bending deformation of the piezoelectric element to change the volume of the pump chamber and transport fluid in the pump chamber. A support member for supporting a back surface of the piezoelectric element is provided so that the support member inhibits bending of a peripheral portion of the diaphragm in a reverse direction. The support member thus prevents the piezoelectric element from being floated. Accordingly, the displacement of the piezoelectric element can be reliably transmitted as the change in volume of the pump chamber, thereby enhancing the fluid transportation performance.

The vibrating plate unit includes a vibrating plate with first and second main surfaces, a frame plate surrounding the vibrating plate, and a link portion linking the vibrating plate and the frame plate and elastically supporting the vibrating plate against the frame plate. The driver is on the first main surface of the vibrating plate, and vibrates the vibrating plate. The flexible plate having a hole faces the second main surface of the vibrating plate, being fixed to the frame plate. At least a portion of the vibrating plate and the link portion are thinner than the thickness of the frame plate so that the surface of the portion of the vibrating plate and the link portion, on the side of the flexible plate, can separate from the flexible plate.

摘要： A fluid conveyance device includes a substrate, and a disk-shaped piezoelectric element arranged in a bendable manner on the substrate. A plurality of substantially circular concentric segment electrodes are provided on the piezoelectric element, and are provided with voltages with phases that are shifted. A wavy ring deformation is thus produced on the piezoelectric element. A pocket produced between the piezoelectric element and the substrate is moved in a radial direction so as to convey a fluid from an outer substantially circular portion to a central portion and to discharge the fluid from the central portion.

摘要： An overturn prevention control device for a two-wheel vehicle having a vehicle body, a front wheel, an actuator that steers the front wheel, a rear wheel, and a rear-wheel driving portion, includes an angular velocity sensor and a control unit arranged to output a steering angle command signal for controlling the actuator. The angular velocity sensor includes a detection axis, is mounted on the vehicle body such that the detection axis is downwardly inclined at a predetermined angle relative to a forward direction of the vehicle body, and detects an angular velocity about the detection axis. The angular velocity detected by the angular velocity sensor includes an angular velocity in a lateral direction of inclination and an angular velocity in an azimuthal direction. The zero-set error and offset noise are incorporated into the azimuth angle command. Thus, the two-wheel vehicle can be prevented from overturning.
