A device for producing sealing rings made of an endless-material. The device includes a feeder unit which conveys and positions the endless-material in a cutting position, a cutting unit which cuts off a section of the endless-material, a gripper unit which grips and displaces the endless-material or the section of the endless-material and which controls a displacement of at least one free end of the section of the endless-material along a predefined path of motion in and/or out of a wetting position, a control device connected with the feeder unit, the at least one gripper unit and/or the cutting unit, and a feeding device for a bonding fluid. The feeding device is connected with the control device and is arranged so that the bonding fluid is deposited in a controlled manner on the at least one free end of the section of the endless material in the wetting position.

[Object] To provide a tube joining device in which the degree of freedom of device design is improved.

[Solving Means] A tube joining device 1 includes a delivery mechanism 500. The delivery mechanism includes a first pusher member 542 that is provided to perform forward movement and backward movement along a delivery direction and delivers a wafer WF to a first position PS2 that is set between a take-out position PS1 at which the wafer WF is taken out from a cassette WC and a stand-by position PS3, and a second pusher member 543 that is provided to perform forward movement and backward movement along the delivery direction in combination with the first pusher member, and delivers the wafer from the first position to the stand-by position. An operation of delivering the wafer by the first pusher member is capable of being switched to an operation of delivering the wafer by the second pusher member in synchronization with forward movement and backward movement of the first pusher member and the second pusher member.

[Object] Provided is a tube joining device which is capable of preventing occurrence of a joining failure caused by a setting error of tubes in advance, and in which tube holding and release of the holding are realized by a simple device configuration.

[Solving Means] A tube joining device 1 includes: a first tube holding portion 160 that is capable of holding a first tube T1; a second tube holding portion 230 that is capable of holding a second tube T2; a tube superimposing portion 30 that disposes the first tube and the second tube in a superimposed manner; and a switching mechanism 240 that is capable of switching holding of the second tube by the second tube holding portion and release of the holding. The switching mechanism applies a biasing force for maintaining a state in which the second tube is held to the second tube holding portion, and applies a biasing force for maintaining a state in which the holding of the second tube is released to the second tube holding portion in accordance with relative approaching of the tube holding portions.

Herein are disclosed apparatus and methods for impinging fluids, e.g. heated fluids, onto the surface of substrates and then locally removing the impinged fluid. The apparatus may comprise at least first and second fluid delivery outlets that are in diverging relation to each other. The apparatus may comprise at least first and second fluid capture inlets that are locally positioned relative to the first and second fluid delivery outlets, respectively. The apparatus and method may be used e.g. to impinge fluids onto two converging substrates and may be used to heat the surfaces of the substrates so as to facilitate melt-bonding the substrates to each other.

A joint structure comprising a light-absorbable member having at least one opening portion and a light-permeable member superposed on the light-absorbable member so as to cover the opening portion, wherein an annular weld part is formed so as to enclose the opening portion and join the light-absorbable member and the light-permeable member, and an area ratio of a portion at the side of the light-absorbable member to a portion at the side of the light-permeable member side is in a range of 12-35 viewing a section perpendicular to the extending direction of the annular weld part.
