Abstract

<B>APARELHO E MéTODO PARA A PREVENçãO DA MIGRAçãO DE ìONS MóVEIS EM UM GIROSCóPIO<D> Um aparelho e um método para a prevenção da migração de íons móveis em um giroscópio. Uma camada de material de barreira dielétrico é colocada entre um corpo do giroscópio e um ou mais componentes do giroscópio. A camada de material de barreira dielétrico reduz o campo elétrico formado no bloco do giroscópio, e assim reduz a migração iónica neste. O material pode impedir que os íons móveis alcancem o selo do catodo.
