Description
Patentkrav 1. Ultralydstransducer (1) til brug ved udsendelse af lyd i en gas eller en væske, hvor transduceren består af et hus Indeholdende en piezoelektrisk skive (11), der virker som svingningselement, og hvor der foran den piezoelektriske skive er anbragt en beskyttende plade kendetegnet ved at den beskyttende plade (4) og huset (5) er fremstillet af elektrisk ledende materialer, og at plade og hus er føjet sammen i en termisk proces under brug af en mekanisk kraftpåvirkning samt en elektrisk strøm, der ledes gennem pladen og huset. 2. Ultralydstransducer ifølge krav 1 kendetegnet ved at den beskyttende plade eller huset er forsynet med et overfladebelægning (16). 3. Ultralydstransducer ifølge krav 2 kendetegnet ved at overfladebelægningen (16) i det væsentlige består af nikkel eller en kombination af nikkel og fosfor. 4. Ultralydstransducer ifølge krav 1 kendetegnet ved at det materiale, som huset er fremstillet af, er forskelligt fra det materiale pladen er fremstillet af. 5. Ultralydstransducer ifølge krav 4 kendetegnet ved at huset består af en kobberlegering, særligt messing, og at den beskyttende plade består af rustfrit stål. 6. Ultralydstransducer ifølge krav 2 kendetegnet ved at både hus og plade består af en kobberlegering, særligt messing. 7. Ultralydstransducer ifølge krav 1 kendetegnet ved at der mellem hus og plade er anbragt et middel såsom en loddering, loddepasta eller flusmiddel til at fremme sammenføjningsprocessen. 8. Ultralydstransducer ifølge krav 2 kendetegnet ved at den beskyttende plade udviser en eller flere fremstående ø'er (15) af overfladebelægningen på den side af pladen (4), der vender ind mod den p[e2oelektriske skive (11). 9. Ultralydstransducer ifølge krav 8 kendetegnet ved at ø'eme har en højde der giver optimal lydtransmission til væsken eller gassen. 10. Ultralydstransducer ifølge krav 1 kendetegnet ved at den beskyttende plade på den side der vender ind mod den piezoelektriske skive udviser fremspring. 11. Ultralydstransducer ifølge krav 1 kendetegnet ved at der mellem den piezoelektriske skive og den beskyttende plade er anbragt et fedtlag, i hvilket der er Iblandet metalpartikler af en størrelse på 1 - 50 μτη. 12. Fremgangsmåde til at sammenføje en ultralydstransducer til brug ved udsendelse af lyd i en gas eller en væske, hvor transduceren (1) består af et hus Indeholdende en piezoelektrisk skive, der virker som svingningselement, og hvor der foran den piezoelektriske skive er anbragt en beskyttende plade kendetegnet ved at den beskyttende plade (4) og huset (5) er fremstillet af elektrisk ledende materialer, og at plade og hus og føjet sammen i en termisk proces under brug afen elektrisk strøm, der ledes gennem pladen og huset. 13. Ultralydstransducer (1) til brug ved udsendelse af lyd i en gas eller en væske, hvor transduceren består af et hus indeholdende en piezoelektrisk skive, der virker som svingningselement, og hvor der foran den piezoelektriske skive er anbragt en beskyttende plade kendetegnet ved at den beskyttende plade (4) er udstyret med fremspring (15) på den side der vender Ind mod den piezoelektriske skive (11).
