摘要： An insert section of an insert member is inserted into a tube member in a state in which the insert member is detached from a recess to form a diametrally expanded section on the tube member. Subsequently, the insert member is fitted to the recess to install the tube member to the recess. At this stage, an outer circumferential surface of an expanded section of the insert member tightly contacts with an inner circumferential surface of the recess to effect the sealing function. Subsequently, a tapered section and an outer circumferential surface of the tube member are resin-welded by using a welding material. Thus, the tube member is prevented from disengagement from a body.

摘要： A suck back valve is proposed which prevents displacement of a diaphragm due to pressure of a supply fluid, together with alleviating concern of changes in the amount of supply fluid which is to be sucked, and enabling ease of installation by making compact the system which employs the suck back valve. A diaphragm is displaced in the direction of arrow A under an activation operation of a linear voice coil type luffing device. Compressed air is introduced into a chamber, wherein the diaphragm is supported under an applied pressure. A coating liquid which is introduced through a fluid passage is supplied onto a semiconductor wafer from a nozzle. When an ON/OFF valve is activated and supply of the coating liquid is prevented, together with activating the linear voice coil luffing device and causing displacement of a plunger in the direction of arrow B, a poppet valve is displaced so that compressed air inside the chamber is output from a fluid output passage. Upon further displacement of the plunger the diaphragm is displaced, whereby the coating liquid is sucked, and any coating liquid in the nozzle is returned in the direction of arrow D.

摘要： When an insert member is inserted into a fluid passage of a fluid tube, the fluid tube is diametrically enlarged by a tapered section. When a female thread of a nut member is meshed with a male thread of a main body section, first and second edge sections are engaged so that they bite into the outer circumference of the fluid tube diametrally enlarged by the tapered section. Accordingly, various fluid tubes, which are identical in outer diameter size but which are slightly different in wall thickness, are reliably prevented from disengagement from a tube joint.
