摘要： An apparatus for separating fibers from a fiber aggregate comprises a hollow cylindrical apparatus housing defining therein a dissolving chamber. A partition is disposed in the internal space of the apparatus housing and forms the bottom of the dissolving chamber. The partition defines a plurality of through openings, through which fibers separated from the aggregate passes. The apparatus housing has an aggregate inlet to introduce the aggregate to be dissolved with pressurized air. The pressurized air carrying the aggregates is discharged toward the partition and forms swirl flow in the dissolving chamber. By the swirl flow of the air, the aggregate flows to collide onto the partition with an impact. This impact serves as an energy for causing dispersion or dissolving of the aggregate. The partition is preferably formed with elastically or resiliently deformable material for absorbing impact upon the collision of the aggregate thereonto so as not to cause destroying of each individual fiber. Further preferably, a contact plate is suspended on the elastically or resiliently deformable partition. The contact plate opposes the aggregate inlet so that the aggregate introduced into the dissolving chamber will collide onto the contact plate.

摘要： A technique for evaluation of the strength of a spot welded portion of a panel is provided. A stress value at the welded portion of the panel is calculated by a stress analysis according to a FEM using the elements, and then the strength of the welded portion is evaluated based on the stress value at the welded portion. A portion in the proximity of the spot welded portion is divided, with a central portion of the spot welded portion registered with a nodal point of the elements, into a central element and plural concentric ring-like elements from the center side provided by the central portion of the spot welded portion. Thereafter, the plural concentric ring-like elements are individually divided in a circumferential direction each into a plurality of portions to form the elements. Then, the strength is evaluated based on the stress value of the second ring-like element.
