    摘要: A liquid-drop discharge device is provided including a float cell provided with a valve and communicating to a liquid storage tank, a liquid discharge mechanism for discharging liquid within the float cell, and a reaction cell provided with a space into which fluid is discharged from the liquid discharge mechanism for collecting the discharged fluid. Air is supplied to the reaction cell for collecting liquid or minute particles, and an internal pressure P1 of the liquid storage tank or the float cell and an internal pressure P3 of the reaction cell are set such that a relationship of P1=P3, in which the pressures are identical to atmospheric pressure, or P1>P3, to supply stronger air, is satisfied.

    摘要: A mass sensor including: a connecting plate having one or more slit(s) and/or opening portion(s) formed therein and/or having a thin-walled portion and a thick-walled portion formed therein; a diaphragm joined with the connecting plate at respective side surfaces; a piezoelectric element; a sensing plate with the piezoelectric element being provided at least at one part on at least one surface of the sensing plate, which has its side surface joined with a side surface of the connecting plate in the direction perpendicular to the joining direction of the diaphragm and the connecting plate; and a sensor substrate with which at least a part of side surfaces of the connecting plate as well as the sensing plate are joined, and the diaphragm, the connecting plate, the sensing plate, and the piezoelectric element form a resonating portion. The mass sensor can conveniently be used for determining the mass of a substance to be sensed by measuring changes in resonant frequencies caused by changes in the mass of the diaphragm on which a catching substance for catching a substance to be sensed by reacting only with the object of sensing is applied.
