摘要： In a liquid drip prevention valve, an input port is formed in the upper face of a flow passage block, and an output port is formed in the lower face, which opposes the upper face of the flow passage block. In addition, a valve chamber is formed on a side face of the flow passage block, and an air block abuts the side face. Furthermore, a diaphragm valve makes contact with a valve seat when pressure is applied with respect to a back side chamber of the diaphragm valve and separates from the valve seat when the back side chamber is brought to negative pressure, thus forming the liquid drip prevention valve.

摘要： There is disclosed a flow control valve which regulates a flow rate by determining a stop position of a piston by contact in an opened state, and which enables remote and high-precision flow rate regulation. In a closed state, an urging force of a return spring acts on a piston, bringing a diaphragm into close contact with a valve seat. In this state, when compressed air is supplied into a pilot chamber, moving the piston, the diaphragm is brought out of contact with the valve seat. Then, the piston comes into contact with a nut and the diaphragm is stopped providing a fixed clearance between the diaphragm and the valve seat. An opened state is established. Of course, the nut can be moved to any desired position by means of a serve motor or the like, so that a position at which the piston comes into contact with the nut can be changed.

摘要： An opening 22d of a supply/withdrawal passage 22b is positioned at the center part of the internal wall surface 22c of the operating chamber 26 (concave area 22a), and a pin 24 that protrudes toward the diaphragm 23 is provided in a position that is offset from the center of the wall surface 22c. When the diaphragm 23 is deformed toward the operating chamber 26 by the suction of an operation air into the operating chamber 26 during drawing in the chemical liquid, a part of the diaphragm 23 opposing to the pin 24 rides on the pin 24 and this part becomes a slightly convex shape toward the pump chamber 25. When the operation air is supplied from the opening 22d into the operating chamber 26 during the discharge of the chemical liquid, the deformation begins first from the part of the diaphragm 23 riding on the pin 24.

摘要： A chemical liquid supply system that prevents the generation of heat during operation in a pump and allows downsizing the discharge pump for instilling a chemical liquid from a tip nozzle. Compressed air is supplied to an upper space of a resist bottle and the chemical liquid is conferred positive pressure and sent out to a pump chamber of a discharge pump, thereby the pump chamber is filled with a resist liquid. This eliminates the need of a conventional construction where a spring or others are used to drive a flexible membrane of the discharge pump to the operation chamber side to take in the resist liquid. As a result, no electric motor is used, so there is obviously no risk of heat damage to a semiconductor wafer and the discharge pump itself can be further downsized.

摘要： An opening 22d of a supply/withdrawal passage 22b is positioned at the center part of the internal wall surface 22c of the operating chamber 26 (concave area 22a), and a cross-shaped venting groove 22e extending from the opening 22d of the passage 22b to the periphery of the wall surface 22c is formed in the wall surface 22c. Thus, an operating air in the chamber 26 is discharged (sucked) through the passage 22b during drawing in the chemical liquid. Since the opening 22d communicates with the venting groove 22e extending to the periphery of the chamber 26, if the center of the diaphragm 23 covers the opening 22d first, the operating air in the chamber 26 can be continuously evacuated (drew out) from the venting groove 22e positioned on the outside of the center part which first comes into contact with the opening 22d
