    • Stable flow control is made possible even under high-temperature environments by relieving tensional force applied to a piezoelectric element when a piezoelectric actuator is retracted. Thus, a piezoelectric driven control valve includes: a body having a valve seat; a metal diaphragm to contact with and separate from the valve seat; an actuator box supported ascendably and descendably on the body; a split base fixed to the body; a disc spring pressing and urging the actuator box downward to bring the metal diaphragm into contact with the valve seat; and a piezoelectric actuator housed inside the actuator box and that extends upward with application of voltage to press the actuator box upward against the elastic force of the disc spring, and a precompression mechanism, for applying a compression force constantly to piezoelectric elements in the piezoelectric actuator, provided between the split base and the piezoelectric actuator.

    • A method for supplying a specified quantity Q of processing gas while dividing at a desired flow rate ratio Q1/Q2 accurately and quickly from a gas supply facility equipped with a flow controller into a chamber. When a specified quantity Q of gas is supplied while being divided at a desired flow rate ratio Q1/Q2 from a gas supply facility equipped with a flow controller into a reduced pressure chamber C through a plurality of branch supply lines and shower plates fixed to the ends thereof, pressure type division quantity controllers FV1 and FV2 are provided in the plurality of branch supply lines GL1 and GL2. Opening control of both division quantity controllers FV1 and FV2 is started by an initial flow rate set signal from a division quantity control board FRC for fully opening the control valve CV of the pressure type division quantity controller having a higher flow rate and pressures P3′ and P3″ on the downstream side of the control valve CV are regulated thus supplying a total quantity Q=Q1+Q2 of gas while dividing into the chamber C through orifice holes (3a, 4a) made in shower plates (3, 4) at desired division quantities Q1 and Q2 represented by formulas Q1=C1P3′ and Q2=C2P3″ (where, C1 and C2 are constants dependent on the cross-sectional area of the orifice hole or the gas temperature on the upstream side thereof).

    • A pressure type flow rate control apparatus (1) controls flow rate of a fluid in an environment where a ratio of P2/P1 between an absolute pressure P1 at an upstream side of an orifice and an absolute pressure P2 at a downstream side of the orifice is maintained at a value less than about 0.7. The apparatus comprises: a plate for forming the orifice (5); a control valve (2) positioned upstream of the orifice; an orifice corresponding valve (9) positioned downstream of the orifice (5); a primary pressure detector (3) positioned between the control valve (2) and the orifice (5); a secondary pressure detector (11) positioned downstream of the orifice (5); a calculation control device (6) for calculating flow rate Qc on the basis of the measured pressure P1 of the primary pressure detector (3) by a formula Qc=KP1 (K being a constant) and for outputting as a control signal Qy a difference between a flow rate command signal Qs and the calculated flow rate signal Qc to a drive unit (14) of the control valve 2; and a pressure comparing, calculating apparatus (10) for calculating the ratio of P2/P1 between the detected pressure P1 of the primary pressure detector (3) and the detected pressure P2 of the secondary pressure detector (11). The pressure P1 upstream of the orifice is adjusted by opening and closing the control valve by the control signal Qy, thereby controlling the flow rate downstream of the orifice.
