摘要:
A prosthesis (10) including a support structure (22) for enhancing kink and/or crush resistance. The support structure (22) is connected to an outer surface (16) of the prosthesis (10) and includes at least two components (23, 24), one of which has a lower melting point than the other. The component with the lower melting point is used to connect the support structure (22) to the outer surface of the prosthesis (10).

Method and machine for joining two objects (1, 5) by anchoring an insert portion (6) provided on one of the objects in an opening (2) provided on the other one of the objects. The anchorage is achieved by liquefaction of a thermoplastic material and interpenetration of the liquefied material and a penetrable material, the two materials being arranged on opposite surfaces of the insert portion (6) and the wall of the opening (2). Before such liquefaction and interpenetration, an interference fit is established in which such opposite surfaces are pressed against each other, and, for the anchoring, mechanical vibration energy and possibly a shearing force (22) are applied, wherein the shearing force puts a shear stress on the interference fit.

The assembly (10) consists of at least one metal insert (14A, 14B, 14C) and one reinforcing sheet (12). The reinforcing sheet (12) contains reinforcing fibres longer than or equal in length to one centimetre. The metal insert (14A, 14B, 14C) comprises protrusions (22) shaped to traverse the sheet (12), passing between the reinforcing fibres, and to fold by plastic deformation, enclosing the reinforcing fibres when said protrusions are subjected to a longitudinal compression force.

摘要:
A holder intended for thin sheets, information sheets and the like, and comprising two parallel plastic panels (1, 2). The plastic panels are joined together along at least two joining lines (3, 4, 5) via spacer material, so as to form between the panels a slot-like space (6, 7) for receiving said thin sheets or information sheets (10, 11). The holder has the form of a one-piece structurre in which the spacing material (9) is formed of material obtained from the plastic panels (1, 2), this material being caused to flow out and from the spacing material that joins the panels together, by a high-frequency welding process. The invention also relates to a method of producing such a holder.
摘要:
Provided is a bonding method and device which can prevent destruction of a layer with low toughness when bonding a film including the layer with low toughness to a bonding target object. A bonding target object and a film including a layer having lower toughness than the bonding target object are disposed between a set of pressurization molds, which have pressurization surfaces disposed so as to face each other and in which opening holes are formed in the pressurization surfaces. A first edge on the opening hole side of the pressurization surface of a first pressurization mold, out of the set of pressurization molds, which faces the film is positioned further inside the opening hole than a second edge on the opening hole side of the pressurization surface of a second pressurization mold which faces the bonding target object. The pressing target portion of the film which is pressed by the set of pressurization molds is bonded to the bonding target object by sandwiching the bonding target object and the film with the set of pressurization molds to be pressed.
