摘要： A semiconductor package includes a print circuit part, a lower chip, an upper chip, a thermal conductivity part, and an encapsulation resin. The lower chip and the upper chip are mounted on the print circuit part through wire bonding connection. The thermal conductivity part efficiently dissipates heat from the chips to the outside of the package. The encapsulation resin entirely seals the package while exposing the thermal conductivity part. A adhesive sheet is hardened to form a bonding layer between the thermal conductivity part and the upper chip, a bonding layer between the semiconductor chips, and a bonding layer between the semiconductor chip and the wired component. The configuration contributes to miniaturization, high integration, and heat resistance reduction of a semiconductor package using high-heat-generating ICs.

摘要： A transverse fan in which a plurality of blades are disposed between disk- or ring-shaped end plates in a circumferential arrangement at fixed mounting pitches in a ring-shaped configuration. Partitions plates are disposed at intermediate portions in the longitudinal direction of the blades such that each of the blades is inclined at fixed angles with respect to a fan axis and mounted at unequal pitches. The transverse fan includes a plurality of multi-bladed impeller units disposed between the disk-shaped end plates. Each of the multi-bladed impeller units has one disk-shaped partition plate having one surface on which a plurality of blades are integrally disposed along a circumferential direction thereof at unequal pitches and inclined at predetermined angles so as to extend along the axial direction of the transverse fan. A plurality of the multi-bladed impeller units are integrally stacked coaxially with each other to form the transverse-fan. The multi-bladed impeller units are integrally stacked one by one in an arrangement such that the units are displaced at predetermined angles with respect to each other around the fan axis.

The prebuffer circuit and the replica buffer circuit are disposed in parallel. The driver circuit temporarily increases input bias current to be supplied to output-stage transistors of the output buffer circuit on the basis of output current of the replica buffer circuit during transition of an input or output signal.
