Abstract: A resin-molded semiconductor device includes: signal leads; a die pad with a central portion elevated above a peripheral portion thereof; support leads, each including a raised portion higher in level than the other portions; and DB paste for use in die bonding. All of these members are encapsulated within a resin encapsulant. The lower part of each of these signal leads protrudes downward out of the resin encapsulant and functions as an external electrode. Each of the support leads is provided with two bent portions to cushion the deforming force. By forming a half-blanked portion in the die pad, the central portion is elevated above the peripheral portion, thus preventing the semiconductor chip from being hampered by the support leads. Accordingly, the size of the semiconductor chip mounted can be selected from a broader range and the humidity resistance of the device can also be improved.

Abstract: An ink ribbon is formed form a belt shaped sheet body, and is wound around a pair of tubes. Spools are detachably mounted at each end of the tube bodies. An ink ribbon cartridge includes side plates formed with supporting openings for supporting corresponding spools. Each supporting opening is formed with a cutout portion defined by edges. When the ink ribbon cartridge is mounted in a facsimile machine, the spools are freely rotatable within the supporting openings. On the other hand, when the ink ribbon cartridge is dismounted from the facsimile machine, engagement protrusions formed to the spools catch on the edges defining the cutout portions, thereby preventing the spools form rotating. As a result, the ink ribbon will not unintentionally greatly loosen.

Abstract: In producing polycarbonates through transesterification of a dicarbonate with a dihydroxy compound, a compound having a specific branched structure and serving as a chain terminator, such as 4-(1,1,3,3-tetramethylbutyl)phenol, is added to the reaction system.

The process provides polycarbonates having well-balanced fluidity and impact resistance, without requiring toxic phosgene as the starting material. The optical-disk substrates as obtained by molding the polycarbonates produced in the process have reduced birefringence and improved transcriptional ability.
