摘要： A fluid control device includes a vibrating plate unit, a driver, and a flexible plate. 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 pump (1) includes a vibrating plate (15) that has a central part (21), a frame part (22), and connecting parts (23 to 26), a piezoelectric element (16) that is stacked over the central part (21) and configured to cause flexural vibrations to occur concentrically from the central part (21) to the connecting parts (23 to 26), and an opposed plate (13) that is stacked over the frame part (22) and positioned facing each of the connecting parts (23 to 26) with a spacing therebetween. The vibrating plate (15) has such a resonant mode that an antinode occurs in each of the central part (21) and the connecting parts (23 to 26). The opposed plate (13) has, at positions facing the connecting parts (23 to 26), a plurality of channel holes (39 to 43) through which a fluid flows.

摘要： An analyzing device includes a heating device, a cooling device, and a controller. The cooling device includes a piezoelectric pump, a check valve, an exhaust valve, and an air tank. The analyzing device heats a subject by the heating device. The cooling device drives the piezoelectric pump while the heating device heating the subject. With this, the outside air is sucked through a suction port and the air that is discharged from the piezoelectric pump is accommodated in the air tank through the check valve. Then, the pressure in the air tank is increased. Thereafter, the cooling device stops driving of the piezoelectric pump. With this, the air in the air tank is discharged toward the subject via the exhaust valve so as to cool the subject.
