A method for joining two objects by anchoring an insert portion provided on one of the objects in an opening 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 and the wall of the opening. 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 are applied, wherein the shearing force puts a shear stress on the interference fit.

There is provided a method for producing a metal-resin composite which includes a resin member and a metal member having a roughened surface in at least a portion of the surface thereof, the resin member being joined so as to be in contact with at least a portion of the roughened surface. The method includes a step of joining the resin member and the metal member by melting the resin member with the frictional heat generated in the surface of the metal member on its side opposite to the resin member in a state where the metal member and the resin member are superposed. The method includes making adjustment so that when the roughened surface is measured at arbitrary five points by using a confocal microscope according to ISO 25178, the developed area ratio (Sdr) is 5 or more in terms of number-average value.

The present invention relates to poly(aryl ether) polymers which can for example be used in lithographic processes for the photofabrication of three-dimensional (3D) articles. The invention further relates to compositions including these poly(aryl ether) polymers. Still further, the invention relates to lithographic methods to form 3D articles or objects that incorporate the aforementioned polymer compositions.

The present application provides an ultrasound probe comprising a housing that includes a coupling interface having a sinusoidal geometry. The housing is formed by a first body (300) and a second body having opposite and corresponding sinusoidal geometries. The first body includes a first proximal portion (105) and a first distal portion (107). The first proximal portion comprises a first sinusoidal shape (326). The second body includes a second proximal portion and a second distal portion. The second proximal portion comprises an opposite second sinusoidal shape. The first body and the second body are coupled to form a handle having a sinusoidal interface. Further, the first distal portion and the second distal portion form a head portion at which the ultrasound transducer assembly is disposed.
