Abstract: A first AC/DC converter circuit is coupled via two transformers to a second AC/DC converter circuit, the first AC/DC converter circuit having a symmetrical configuration of two switching elements performing complementary opened/closed switching, to alternately connect positive and negative terminals of a DC source to a junction between transformer primary windings. Each primary winding alternates between a condition of transferring electrical power to a secondary winding and a condition of serving as a choke coil which temporarily stores electromagnetic energy when a current flows through that primary winding and a primary winding of the other transformer.

Abstract: Aspects of the invention provide solder compositions which include two different fluxing agents. One of the fluxing agents promotes melting of a metal of the solder at a first activation temperature and the other fluxing agent promotes melting of the metal at a second activation temperature that is higher than the first activation temperature. This dual-flux solder may be used in manufacturing microelectronic components and microelectronic component assemblies. In one specific application, the solder may be used to manufacture a flip chip or other microelectronic component which includes self-fluxing solder balls. This can obviate the need to apply another flux composition to the solder balls prior to a subsequent component attach reflow operation.

Abstract: A vehicle body panel having a honeycomb sandwich structure in which a honeycomb core is sandwiched between a first and a second plate includes a subhoneycomb panel formed by adhering the first plate to one major surface of the honeycomb core beforehand. The subhoneycomb panel is pressed against the second plate which is constituted by a part of a structural panel of a vehicle body with the intermediary of an adhesive layer, the other major surface of the honeycomb core being adhered to the second plate. The connection of the subhoneycomb panel to the second plate is performed after the structural panel has been connected to a strength member of the vehicle body, e. g. after a washing stage. Such a vehicle body panel with a honeycomb sandwich structure is achievable without resorting to any substantial modification of an existing vehicle body assembly line.
