摘要:
A semiconductor device comprising at least one heat sink joined to a plurality of IC packages mounted on a mother board. Plural individual heat sinks are joined to respectively corresponding IC packages each comprising a central shaft joined to and extending in substantially perpendicular relationship from a respective said package and plural, parallel spaced fins extending outwardly from and in perpendicular relationship to the shaft. A common heat sink for plural IC packages comprises a base board portion, a heat conducting shaft portion arranged perpendicular to the base board portion and a plurality of heat dissipating fins arranged perpendicular to said heat conducting shaft portion and in parallel, spaced relationship to each other, the common heat sink having one or more slits which are formed parallel to and extending through the heat conducting shaft from the base board portion to midway of the height of the heat conducting shaft and defining a plurality of sections of the base board portion, respectively, joined to the plurality of IC packages.
摘要:
A nitrogen-containing heterocyclic derivative represented by the following general formula (I), or a hydrate or solvate thereof, which has a selective antagonistic action on the muscarinic M3 receptor and causes reduced cardiac side effect and thus is safe, and has superior pharmacological efficacy and prolonged action even by inhalation administration, and a pharmaceutical composition comprising the compound and a pharmaceutically acceptable carrier.
摘要:
An interactive graphic system is provided which introduces drawing data step by step in the form of interaction to describe figures, characters, numerical figures or the like with the aid of a microcomputer. The interactive graphic system consists of a keyboard for introducing drawing data, a plotter for recording the figures, a microcomputer, and a memory unit that are constructed as a unitary structure which features small size, reduced cost and enhanced operational performance. Further, the interactive graphic system is so constructed that application software packages can be freely exchanged to diversify the functions.
