摘要： 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.

摘要： 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.

摘要： The present invention provides a piezoelectric acoustic device 2 capable of preventing substantial deflection of a first side wall 17 opposite a piezoelectric vibrator 13 due to application of force to an integral cylinder 12 in a direction toward the first side wall 17. According to the invention, a piezoelectric vibrator 13 including a piezoelectric ceramic element is received in a two-part receiving casing 9 formed by fitting a first casing half 10 and a second casing half 11 together. The first casing half 10 includes a first side wall 17 opposite to the piezoelectric vibrator 13 and a first peripheral wall 18 extending from the first side wall 17. A front air chamber 30 is defined between the first side wall 17 and the piezoelectric vibrator 13. A cylinder 12 is integrally formed on the first side wall 17 so as to extend in a direction perpendicular away from the plane of the first side wall 17. The cylinder 12 is offset toward an outer periphery of the first side wall 17 so that a part 32 of the base 31 of the cylinder 12 is aligned with a part of the first peripheral wall 18 of the first casing half. An opening 23 is provided through the first side wall 17 for connecting the front air chamber 30 to a passage 29 defined by the interior of the cylinder 12. The opening 23 is situated such that a center 28 thereof is offset toward a center point 25 of the first side wall 17, and is preferably adjacent to the inner periphery of the cylinder 12. The opening 23 is covered with a damping cloth member 27 joined to an inner surface 26 of the first side wall 17 by means of a solvent which dissolves the synthetic resin from which the front casing half 10 is formed but not the damping cloth member 27.

摘要： 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.

摘要： A transfer machine is provided with a plurality of machining units disposed in positions to correspond respectively to machining stations which constitute parts of a transfer line. Each of programmable sequence controllers respectively associated with the machining units has a program memory storing a plurality of workpiece-dependent control programs and controls the operation of an associated one of the machining units in accordance with one of the workpiece-dependent control programs designated by a data processor. The data processor is provided with a memory which stores part numbers of the workpieces respectively held on the machining stations and the kinds of machining cycles in which each of the workpieces is scheduled to be machined respectively at the machining stations. Each time the transfer line performs one-pitch transfer of the workpieces therealong, the data processor rewrites the part numbers being stored in the memory so as to renew part numbers of the workpieces being respectively held on the machining stations. The data processor then outputs program designation data based upon the part numbers and the kinds of machining cycles scheduled in the memory, so that each of the sequence controllers controls the associated machining unit in accordance with one of the workpiece-dependent control programs selected by the program designation data.
