The device for welding thermoplastic parts includes a matrix for positioning the parts to be assembled, the matrix including an amagnetic insulating insert that defines joining zones in which the welds must be produced, a bladder defining a sealed volume and means for producing a partial vacuum in the sealed volume, and means for moving a magnetic induction head to near the joining zones and without making contact with the bladder. The welding process includes positioning at least one first part, then of placing metal inserts on areas of the first part corresponding to the joining zones that must be welded, and then positioning at least one second part. A bladder is put in place covering the parts and a partial vacuum is created in the volume defined by the bladder. The magnetic induction head is moved to produce the weld bead without contact while the partial vacuum is maintained.

A laminating device includes a first jig on which a first member is seated, a second jig facing the first jig, and a second member between the first jig and the second jig. The second jig includes a pad part having a top surface on which the second member is seated, the pad part having elasticity, a pad deformation part configured to support a rear surface of the pad part, and a support part to support the pad deformation part. The pad deformation part couples the pad part to the support part, and a portion of the pad deformation part has a recessed plate shape with respect to the pad part to correspond to a position thereof coupled to the support part.

A method for manufacturing a liquid supply member that supplies a discharge port with liquid includes preparing a transparent member and an absorption member, at least one of both members having a groove for a supply path; bringing both members into contact; and forming the supply path by emitting laser beams simultaneously from a plurality of laser beam sources, toward a contact portion, which is provided in a vicinity of the groove and at which both members are in contact, to weld both members. Laser beams are emitted during the forming such that a total laser-beam irradiation amount per unit area for a first portion included in the contact portion and located in a vicinity of an end in a longitudinal direction of the groove is larger than that for part with a smallest irradiation amount of a second portion other than the first portion of the contact portion.

A protective film includes an adhesive material configured for dry application to a surface that is to be protected, such as the surface of an electronic device. An installation assembly that includes the protective film is configured to minimize or eliminate contact with the protective film as it is applied to the surface that is to be protected. Methods for manufacturing a protective film and an installation assembly that includes the protective film may be effected in contaminant-free conditions. Methods for applying the protective film are also disclosed, as are devices (e.g., electronic devices, etc.) with at least one surface covered with a protective film.

A method for quickly applying and spreading adhesive between substrates without leaving air bubbles. The method includes holding two substrates apart from each other with adhesive sides facing, a second substrate being positioned above a first substrate. The second substrate is suspended in a manner so as to cause a portion to warp towards the first substrate. After a liquid filler is applied between the two substrates, rollers are lowered onto the second substrate and moved so as to disperse the liquid filler between the first and second substrates. In accordance with the rolling of the rollers, end portions of the second substrate are lowered towards the first substrate.

A sheet pasting device EA includes: a sheet feed unit 10 that feeds an adhesive sheet AS; and a press unit 20 that has a press roller 22 for pressing the adhesive sheet AS against a work WK and that pastes the adhesive sheet AS on the work WK by pressing the adhesive sheet AS against the work WK moving relative to the press roller 22, the press unit 20 bringing the press roller 22 into contact with an attachment surface WK1 of the work WK and rotating the press roller 22 on the attachment surface WK1, at a stage before pressing the adhesive sheet AS against the work WK using the press roller 22.

An induction welding assembly and inductive welding method is disclosed. A tooling block includes a workpiece zone, a conductive heat generation and transfer member, and a heat shield, with the conductive heat generation and transfer member being disposed between the workpiece zone and the heat shield. A first workpiece and a second workpiece may be disposed within the workpiece zone such that the first workpiece is disposed between the conductive heat generation and transfer member and the second workpiece. The heat shield, conductive heat generation and transfer member, first workpiece, and second workpiece may be pressed together. An induction coil may be positioned in spaced relation to the heat shield and may be operated to heat the conductive heat generation and transfer member. Heat is conductively transferred by the conductive heat transfer member to the first workpiece to weld the first workpiece and the second workpiece together.

A device for joining a first component to be welded to a second component to be welded, the joining device having at least one electrically conductive, resistive heating film which comprises a central connection portion and two lateral electrical connection portions. The joining device comprises at least one first electrical insulation member which is positioned in contact with the first face of the heating film, and at least one second electrical insulation member which is positioned in contact with the second face of the heating film, the two electrical insulation members being configured to allow the transfer of heat and to prevent the flow of electric current between the heating film and each component to be welded.

A method and apparatus for deploying a tubular body onto a surface. The apparatus includes a main body movable in an advancing direction. The apparatus includes a deployment mechanism that deploys a tubular body directly onto a surface. The apparatus includes at least one container that stores an uncured protectant. The container is mounted on the main body. The apparatus may include a second container that stores a second protectant. The second protectant is different than the uncured protectant. The apparatus includes at least one curing device, which can cure the uncured protectant after the uncured protectant is applied to surface.
