    Abstract: A pump unit (100) includes a plurality of piezoelectric pumps (1), a flow path-defining member (50), and a heat-dissipating part (60). The plurality of piezoelectric pumps (1) each include a first flow path for sucking and discharging of fluid. The flow path-defining member (50) includes a second flow path for connection to the first flow paths in the plurality of piezoelectric pumps (1). Heat generated in the plurality of piezoelectric pumps (1) is dissipated through the heat-dissipating part (60). The heat-dissipating part (60) is disposed between the flow path-defining member (50) and each of the plurality of piezoelectric pumps (1). The heat-dissipating part (60) has through-holes through which the first flow paths are connected to the second flow path.

    Abstract: A piezoelectric blower (100) includes a housing (17), a vibrating plate (41), and a piezoelectric element (42). The vibrating plate (41) forms a column-shaped blower chamber (31) together with the housing (17). The vibrating plate (41) and the housing (17) are formed so that the blower chamber (31) has a radius a. The piezoelectric element (42) causes the vibrating plate (41) to concentrically bend and vibrate at a resonance frequency f. A recessed portion (26) is formed in the housing (17) on the side facing the vibrating plate (41). The recessed portion (26) defines a cavity (25), which constitutes the blower chamber (31) and communicates with the vent hole (24). The radius a of the blower chamber (31) and the resonance frequency f of the vibrating plate (41) satisfy a relationship of 0.8×(k0c)/(2π)≦af≦1.2×(k0c)/(2π).

    Abstract: A forward check valve and a fuel cell system are provided which include a valve portion including a valve body, a supporting portion, a hole, and a fixation portion. The valve body contacts a valve seat when the valve portion is accommodated in an opening. The supporting portion supports the valve body so that the valve body is movable in directions in which the valve body moves towards and away from the valve seat. The fixation portion contacts an inner peripheral surface defining the opening of a valve housing to fix the supporting portion when the valve portion is accommodated in the opening. The fixation portion includes protruding portions that protrude from a mount surface of the valve housing when the valve portion is accommodated in the opening. By fitting the valve portion to the opening, the valve portion is accommodated in the opening of the valve housing.

    Abstract: A processor obtains a body temperature and patient condition information of a patient via a communication device. The processor calculates a comparison result by comparing the body temperature with a reference temperature obtained by the communication device and outputs a risk related to the health status of the patient based on the comparison result. The processor performs at least one of a process of correcting the body temperature based on the patient condition information when comparing the body temperature with the reference temperature, a process of setting the reference temperature based on the patient condition information when comparing the body temperature with the reference temperature, and a process of increasing or decreasing the comparison result based on the patient condition information.

    Abstract: A fluid control device includes piezoelectric pumps and a substrate. The substrate includes dielectric base members. Each of the dielectric base members has a recess and a through-hole. Each of the dielectric base members is laminated such that the recesses of the dielectric base members partially overlap and communicate with each other. A portion of the recesses not overlapping with the dielectric base member serve as a first opening and a second opening, respectively, to the outside. The first opening and the second opening open in opposite directions in the lamination direction. The first opening and the second opening have shapes that may be fit to each other. The piezoelectric pump is on the dielectric base member to communicate with the through-hole, and the piezoelectric pump is on the dielectric base member to communicate with the through-hole.
