Abstract

Patente de Invenção: <B>"APARELHO DE IMPRESSãO POR JATO DE TINTA DO TIPO DEMANDA DE GOTA"<D>. Um aparelho de jato de tinta do tipo demanda de gota utilizando um atuador piezelétrico disposto de modo a defletir em um modo de cisalhamento. O aparelho é formado de uma pluralidade de placas laminadas dispostas de modo a definir uma câmara de tinta (22). O atuador forma um lado da câmara e deflete no sentido de um bocal (19), formado em uma placa de bocais (18), que proporciona o lado oposto da câmara. Uma camada de interligação (21) age como o substrato e tem orifícios (12), para permitir que feixes (13) passem através da microplaqueta controladora. Sobre o lado oposto da camada de interligação encontra-se a folha piezelétrica (4). Os eletrodos (24, 25) são proporcionados entre a camada de interligação e a folha piezelétrica. A folha piezelétrica é entalhada, furada ou moldada, de modo a proporcionar canais de tinta paralelos (15) e uma depressão circular com um reservatório central saliente (23). A folha piezelétrica é ligada à placa de interposição ou eletrodo terra que é, por sua vez, ligado à placa de bocais. Quando uma carga é aplicada entre os dois eletrodos, um atuador selecionado (10) da folha piezelétrica (14) deflete em um modo de cisalhamento no sentido da placa de bocais. Este movimento proporciona energia suficiente para ejetar uma gotícula do bocal. Poderiam ser aplicados vários pulsos curtos, de modo a aumentar o tamanho da gotícula ejetada. Várias câmaras de pressão distintas
