摘要： A lead frame having a body with oppositely facing, substantially planar, first and second surfaces respectively facing in first and second directions and residing in first and second substantially parallel reference planes. The body defines a support for a semiconductor chip and a plurality of leads. The support has a third surface facing in the first direction to which a semiconductor chip can be mounted, and a fourth surface facing in the second direction. At least a part of the fourth surface is spaced from the second reference plane towards the first reference plane.

摘要： A method is disclosed for constructing a dual-sided chip package onto a leadframe having a die pad and a set of lead fingers corresponding to the die pad. Integrated circuit dies are disposed onto each side of the die pad while the leadframe is supported with support blocks having cavities that accept the integrated circuit dies and that support each lead finger and that provide clearance for stitch bonds of the previously formed wire bonds. Thereafter, a one step plastic mold is formed around each assembly comprising the dual integrated circuit dies, the die pads, and the wire bonds.

摘要： An object of the present invention is to provide a combustion chamber shape of a direct injection type diesel engine in which a black smoke generation amount can be suppressed during no-load operation while suppressing NOx and fuel consumption. The combustion chamber 5 is formed in a recessed shape in a piston top wall 3 and injecting fuel at a predetermined nozzle hole angle α into the combustion chamber 5 from a nozzle hole 20 of a fuel injection valve having a nozzle hole center O1 substantially on a cylinder center line. A wall face of the combustion chamber 5 includes: a conical mountain portion 12 formed at a central portion in the combustion chamber and having such a slope angle and skirt end diameter D2 that fuel spray does not collide with the mountain portion; a slope portion 14 that inclines downward and outward from a skirt end of the mountain portion 12 at a smaller angle than the slope angle of the mountain portion 12 and with which the fuel spray collides; and a saucer portion 15 which rises in an arc shape from an outer peripheral end of the slope portion 14 to reach an outer peripheral end of the combustion chamber and with which the fuel spray collides.

摘要： A diesel engine including a shallow-dish type combustion chamber on the top face of a piston. A fuel injection valve projects toward the combustion chamber, where a plurality of first nozzle holes are arranged in the same circumference of the fuel injection valve. A plurality of second nozzle holes having a diameter smaller than that of the first nozzle holes are provided in a circular side wall of the fuel injection valve, the circular side wall locating opposite to the tip part of the valve with respect to the first nozzle holes. The first nozzle holes and the second nozzle holes are staggered so that the sprays of the fuel ejected from the first nozzle holes and the second nozzle holes do no cross one another.
