A chip storing device includes a supporting frame, an elastic airbag and an airtight container. The supporting frame includes a loading tray having a receiving slot and a positioning portion. The receiving slot is used for containing a packaged chip. The positioning portion is disposed within the receiving slot, and used for limiting the elastic airbag. The airtight container is formed with an accommodating space therein. The supporting frame and the elastic air bag are completely received within the accommodation space. when the accommodation space is evacuated to be in a negative pressure environment, the volume of the elastic airbag is increased in the negative pressure environment, so that the elastic airbag that is inflated directly abuts against the packaged chip within the receiving slot.

A cassette for accommodating glass includes: a cassette main body for accommodating a plurality of glasses; a housing arranged on at least one side of the cassette main body and including a plurality of openings arranged side by side in one direction; and a plurality of doors configured to open and close the plurality of openings.

A separator bead is disclosed for separating layers of manufactured concrete products, wherein the separator bead is characterized in that: the separator bead is preferably fabricated from a biodegradable bead material; the separator bead is configured with a thickness selected from 2 mm to 5 mm, a width selected from 2 mm to 10 mm, a depth selected from 2 mm to 10 mm, and a thickness-to-width aspect ratio selected from 0.2 to 0.9; the separator bead is preferably configured with one or more nodules, each with a nodule diameter selected from 0.01 mm to 2 mm; and the separator bead is characterized by a thickness compression from 5% to 50%, under a load of 60 lb per bead at a temperature of 120 F. for 5 minutes. The disclosed separator beads overcome known problems in the art of manufactured concrete products. The optimized separator beads prevent surface scratches and defects.

A cassette for accommodating glass includes: a cassette main body for accommodating a plurality of glasses; a housing arranged on at least one side of the cassette main body and including a plurality of openings arranged side by side in one direction; and a plurality of doors configured to open and close the plurality of openings.
