This semiconductor device is a semiconductor device in which a semiconductor element is flip-chip mounted onto a circuit substrate and the semiconductor element is covered and sealed with a sealing resin. A recess portion is formed in the sealing resin on a surface opposite to the mounting surface of the semiconductor element. Warping of the semiconductor device is reduced by the action of this recess portion.

A composition for diagnosing amyloid-related diseases, which comprises a flavone derivative, a chalcone derivative, a styrylchromone derivative, or a coumarin derivative, is provided. These compounds have high binding specificity to an amyloid β protein, high permeability to a blood-brain barrier, and ability to rapidly disappear from sites other than cerebral senile plaque. Accordingly, the composition of the present invention using these compounds enables the diagnosis of amyloid-related diseases with high precision.

It is intended to provide novel amine compounds which are efficacious against diseases such as infection with HIV virus, rheumatism and cancer metastasis. Namely, amine compounds represented by the following general formula (1): In a typical case, A1 and A2 represent each an optionally substituted monocyclic or polycyclic aromatic heterocycle; W represents cyclic C3-10 alkylene, an optionally substituted monocyclic or polycyclic aromatic heterocycle, a monocyclic or polycyclic aromatic ring or a partly saturated polycyclic aromatic ring; X represents O, CH2, C(═O) or NR11; and D is a group represented by the following general formula (4) or (6). In the formula (6), Q represents a single bond, S, O or NR12; and Y is a group represented by the following general formula (7). z represents an optionally substituted monocyclic or polycyclic aromatic ring. In the formula (6), B represents NR25R26. In the above formulae, R1 to R26 each represents hydrogen, alkyl, alkenyl or alkynyl.

A packet transfer apparatus includes a packet classifying section and scheduler. The packet classifying section identifies a connection used for transfer of data between a transmission terminal and a reception terminal from not less than one field contained in a header of a reception packet received from the transmission terminal and detects establishment and release of the connection. The scheduler performs transfer control on a reception packet for each connection on the basis of the connection information of each connection identified by the packet classifying section. A packet transfer method and a program are also disclosed.
