摘要:
To simplify fitting and sealing the crystal (4) to the casing (2, 6, 8), assembly is effected by means of ultrasonic welding. The casing (2, 6, 8) and the crystal (4) are made of synthetic materials which are thermo-weldable to each other. The mating faces (8a, 4b) of the peripheral wall (8) of the casing and the crystal (4) are formed for reducing the contact area between the two parts to permit thermo-welding by subjecting the assembly to high-frequency mechanical vibrations imparted by a tool (15).
摘要:
An electronic watch in which the inside face of the glass 6 of the watch comprises, on its periphery, conductor deposits (10, 16, 22, 32) forming the conductor tracks of a printed circuit, the insulating substrate of which is formed by capacitor 14, the resonator 20 or the integrated circuit 18 are fixed directly on the glass. Electrical contact means (12, 28, 30, 46) form the connections between the conductor tracks and other components which are housed in the watch casing. A deposit (8) forming a masking means on the outside face of the glass hides the printed circuit and the components.

The watch casing 102 is made of plastics material. The stator 2 of the motor serves at the same time as the support for the rotor 32 and as a plate for the spindles 18, 22, 24 for the hands and the gear train 48, 46, 47, 20. The printed circuit 304 is secured to the bottom 104 of the casing by heat-sealing. The cell is housed in a chamber 262 disposed in a thick portion of the bottom of the casing.

A cover 20 for a cell cavity 7 in a plastic watch case 2 is provided on its periphery with three lugs 28. The back surface 4 of the case is provided with three recesses 12 into which the lugs can enter freely. With the aid of a tool 38, the cover is rotated while ultrasonic or thermal energy is applied to the lugs. Thanks to this energy, the lugs themselves deform and move into the thermoplastic material in order thereby to form three undercuts. A bayonet joint closure assembly is thus formed. See FIG. 5.

摘要:
A suture anchor retaining a suture is fixated in hard tissue, in particular in bone tissue, using any per se known method and is then secured using a securing element including a material having thermoplastic properties, which is liquefied in situ and made to penetrate the hard tissue in which the suture anchor is fixated. The securing element is e.g. a thermoplastic plug or thermoplastic sleeve which is anchored above the suture anchor in a mouth area of the same hard tissue opening. Alternatively the securing element is a thermoplastic pin which is introduced into an inner cavity of the suture anchor, wherein the material having thermoplastic properties is liquefied in this cavity and, in a liquid state is pressed through passages connecting the cavity with outer surfaces of the anchor.

A first and a second object (1 and 2) are joined with the aid of a joining element (8) including at least in the region of its distal and proximal ends (8.1 and 8.2) a thermoplastic material. Two blind holes (5 and 6) facing each other are provided in the two objects (1 and 2) and the joining element (8) is positioned in the blind holes such that its distal and proximal ends (8.1) are in contact with the bottom faces of the blind holes and such that there is a gap (9) between the two objects (1 and 2). This assembly is then positioned between a support (3) and a sonotrode (4). The sonotrode (4) and the support (3) are forced towards each other, while the sonotrode (4) is vibrated, thereby liquefying at least part of the material having thermoplastic properties, there, where the joining element ends (8.1 and 8.2) are pressed against the bottom faces of the holes (5 and 6) and allowing the liquefied material to infiltrate into pores of the hole surfaces or unevennesses or openings provided in the hole surfaces.
摘要:
A method for joining bodies by melting down a joining element. The joining element acts on a surface of one of the bodies and penetrates the surface as a result of a directed force. Once in a penetrated condition, a mechanical excitation is generated such that during further penetration of the joining element into the one body, the advance is maintained through the directed force and the melting down is maintained through the mechanical excitation. Molten or melted material is hydraulically displaced into the bodies.

The invention is a medicament magazine having at least one medicament chamber for use in a powder inhaler, wherein the magazine is formed from two foil strips applied to one another and the at least one medicament chamber is formed between the foil strips. The medicament chambers have an internal structure (3) which comprises in its interior a space for receiving a powdered medicament and stabilises this inner space against external mechanical influences. In another embodiment in which the internal structure preferably also has a stabilising function, the structure has means for opening one foil strip. In addition, the medicament chamber contains a retaining device which holds the internal structure on the medicament magazine after the medicament chamber has been opened.

The invention concerns a medicine dispensation device, in particular a multi-dose powder inhalator, for the dispensing of individual doses of medicine as depicted in exemplary FIG. 1. Therein a number of medicine chambers are contained in a medicine magazine shaped like a continuous loop. The medicine chambers form groups in such a manner that a mouthpiece reaches the different groups by an essentially complete rotation of the medicine magazine. This enables several medicine chambers—typically one, two or three—to be situated between two successive intake positions, which allows for a high density of medicine chambers and thus creates an inhalation device, which can be handled comfortably even when containing a great number of individual doses.
