Abstract

Patente de Invenção: <B>"INICIADOR PIROTéCNICO COM FILAMENTO FOTOGRAVADO PROTEGIDO CONTRA AS DESCARGAS ELETROSTáTICAS"<D>. A presente invenção refere-se ao domínio dos iniciadores eletropirotécnicos comportando um circuito com folhas em camadas espessas. O circuito elétrico é fotogravado sobre um suporte isolante (16). Ele é constituído por uma primeira folha resistiva, apresentando uma parte mediana (17) de largura constante. Essa primeira folha é recoberta, salvo sobre a parte mediana (17), por duas camadas condutoras (28, 29) em cobre. O circuito (18) tem um contorno constituído de linhas curvas cujo raio é superior a 7x10^ -4^ m e cuja menor distância em relação à borda do suporte (16) é pelo menos igual a 35x10^ -5^ m. Esse iniciador apresenta uma resistência reforçada às descargas eletrostáticas.
