Some spectral approximations for di erential equations in un-bounded domains

A hinged chassis arrangement in a television receiver which is especially adaptable to automated or semi-automated manufacturing and testing techniques. The hinged chassis arrangement utilizes a sub-chassis removably hinged to a principal chassis. During assembly the principal chassis and the sub-chassis are substantially coplanar such that all electrical and mechanical components are mounted from the top into terminal strips extending downwardly through the chassis. After dip-soldering and testing, the sub-chassis is rotated to position upwardly perpendicular to the principal chassis. Component module boards having electrical components mounted thereupon comprising electrical circuits are then affixed to the back of the sub-chassis by female connectors utilizing the extending terminal strips as male connectors.
