Abstract: In the manufacture of packaging containers, for example blown plastic bottles, a circular material blank is, in certain cases, fixedly welded to the end of a sleeve-shaped casing portion. It is advantageous from amongst other energy viewpoint if the welding can take place using ultrasound, but in this instance it has been proved that the central region to the circular blank absorbs ultrasonic energy to such an extent that it is deformed or breaks. A method of using ultrasound to fixedly weld a circular material blank without such drawbacks occurring is proposed according to the present invention in that the oscillations caused by the ultrasound are reduced by a mechanical stabilization of the central region of the circular blank, which is put into effect with the aid of a vacuum and a relief pattern provided in the central region of the circular blank.

Such welding is conducted by vibrating two fiber reinforced thermoplastic parts under pressure along their common interface to generate frictional heat to melt and fuse their surfaces together.

Abstract: A connecting pad of a magnetic head element is bonded to a signal conductor of a supporting beam. As a result of the bonding, the magnetic head element is mechanically coupled to the supporting beam and the connecting pad is electrically connected to the signal conductor. Also an auxiliary pad of the magnetic head element is bonded to the signal conductor. This bonding improves the mechanical coupling strength of the magnetic head element to the supporting beam. When the magnetic head element is to be bonded to the supporting beam, one of the pads is bonded to the signal conductor, and thereafter the other pad is bonded to the signal conductor. During the process of the latter bonding, a groove which is previously disposed in the signal conductor blocks heat given for the bonding from being transmitted to the former bonding portion in which bonding has been already completed, thereby preventing the bonding of the former bonding portion from being broken.
