An interrupt control apparatus and interrupt control method reduce situations in which the output of interrupt information is suspended and thus reduce stress caused in a user, without missing the appropriate output timing for interrupt information having a high priority level. The agglomerates, made by feeding wet chopped fiber strand segments into a wave chamber having a vibrating curved surface that produces a wave-like flow pattern in the segments and agglomerates, have a substantially higher bulk density and greatly improved flow characteristics than conventional chopped strand reinforcements. The lock comprises a lock body and a retainer. Each first solid metal post includes a base region adjacent the microelectronic element and a tip region remote from the microelectronic element, the base region and tip region having respective concave circumferential surfaces.
