摘要： 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).

摘要： In a step motor driven cam valve a stem freely ascends and descends within a body having an in-flow passage, an out-flow passage, a valve chamber, and a valve seat. The stem is descended by an actuator, composed of a step motor and a cam mechanism located at a position above the stem, that changes a rotational motion of the step motor to a linear motion and transmits the linear motion to the stem. A diaphragm within a valve chamber or a valve body at a lower end part of the stem rests on the valve seat. A lift support mechanism that supports the actuator to freely ascend and descend is arranged at a bonnet that covers the valve chamber. A height fine-adjustment mechanism, arranged at the lift supporting mechanism, finely adjusts the height of the actuator relative to the stem so as to perform zero-point adjustment of the valve.
