摘要:
The present invention features a lead-frame package, having a first, second, third and fourth electrically conductive structures with a pair of semiconductor dies disposed therebetween defining a stacked structure. The first and second structures are spaced-apart from and in superimposition with the first structure. A semiconductor die is disposed between the first and second structures. The semiconductor die has contacts electrically connected to the first and second structures. A part of the third structure lies in a common plane with a portion of the second structure. The third structure is coupled to the semiconductor die. An additional semiconductor die is attached to one of the first and second structures. The fourth structure is in electrical contact with the additional semiconductor die. A molding compound is disposed to encapsulate a portion of said package with a sub-portion of the molding compound being disposed in the volume.

The present invention comprises a condiment shaker/crusher for crushing, holding and dispensing seasonings to add taste to edible food. The condiment shaker comprises a body member having an opening. The body member is made of a squeezable material and defines an interior space for holding the seasonings to be crushed and dispensed. A top is removably engaged about the opening of the body member.
摘要:
Resin compositions, layers, and interlayers comprising two or more thermoplastic polymers and at least one RI balancing agent for adjusting the refractive index of at least one of the resins or layers is provided. Such compositions, layers, and interlayers exhibit enhanced optical properties while retaining other properties, such as impact resistance and acoustic performance.
