Abstract: [Object] To provide a rolling apparatus that enables an operator to recognize the rolling status such as the behavior of the steel sheet entering the rolling stand and enables a stable rolling process. [Solution] A rolling apparatus 10 includes a plurality of rolling stands 11 each including a pair of rolling mills 12, and an imaging unit 15 provided between adjacent rolling stands 11A and 11B, the imaging unit 15 being configured to image a steel sheet 1 entering a pair of rolling mills 12B of the rolling stand 11B from an upstream side of the rolling stand 11A located on a downstream side in a rolling direction.

Abstract: A polyhedral IC package is provided with a plurality of pins for the purpose of connection to an semiconductor chip on each of the faces thereof, this IC package being stacked or arranged in a row by causing these pins to coincide with one another, thereby enabling three-dimensional arrangement of the IC package and in increase in the number of pins, without having to make the spacing between pins narrower. It is possible to provide an access hole on each face of the polyhedron for the purpose of enabling a physical interface.
