US Classification:

438123

Abstract:

A method of producing a glass/metal package where a glass portion of the package is built up around a provided leadframe (10) using applications of solderable and glass pastes (20) which are subsequently fired (30). The glass paste and leadframe are chosen to have similar coefficients of expansion and the leadframe is pretreated to degasify and control oxidation of the metal to promote glass adhesion to the leadframe and prevent microcracking at a glass/metal interface. A seal ring is applied to the glass paste (40) and a lid is attached to the seal ring (50). The package is used to provide an sealed inert internal environment for sensitive electronic components such as a piezoelectric element. The package may be configured for leaded or surface mounting (60).

Abstract:

A carrying case for a portable cardiac pacer having physician-actuable controls on the top and front panels of its housing includes a body portion having front, rear, side and bottom panels forming an open-ended enclosure in which the pacer is received. A first hinge-mounted flap extending across the open-end of the enclosure and a second hinge-mounted flap extending across the front panel of the body portion are secured at their free ends by a snap-fastener to the front panel of the body portion so as to retain the pacer securely seated within the enclosure. each of the flap panels includes a rigid portion overlying the associated panel controls of the pacer to prevent inadvertent actuation of the controls by pressure applied externally to the carrying case.
