Patent JP-H11171263-A (JP)
Title: Simple container
Inventor: HATSUSE HIDEAKI
IPC: B65D3/22
Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To obtain a thermal insulation container which is relatively small in amount of the use of paper, simple in structure, and low in cost, by joining a paper sheet with a plurality of recesses or projections formed on it onto the external surface of the body. SOLUTION: Since a paper sheet 20 with hemispherical projections 22 formed on it is stuck to the outside of paper container whose internal surface is laminated with a thin film of polyethylene, most of the container is made of paper, therefore the low-cost, disposable type simple container can be obtained. Also, because the paper sheet 20 with the hemispherical projections 22 is joined to only the upper part of the body of the container, an amount of the use of the paper sheet 20 is very small, which reduces an amount of the use of base paper, and hence the cost. Furthermore, the part of such a paper sheet 20 where the hemispherical projections 22 are formed can be gripped with hand, and drink in it can, therefore, be taken without directly touching the body 10 with the hand.

IPC: G01N21/95
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To optically inspect vias in a wafer stack by allowing a dielectric layer disposed on a metal layer to have a plurality of vias etched with an etchant, which is configured to etch the metal layer at a faster rate than the dielectric layer. SOLUTION: A wafer stack 200 has a plurality of bias 210, 212, 214, 216, 218, and 220 etched in a dielectric layer 208 disposed on a conductor layer 206. The conductor layer is made of, for example, a metal. For this structure, since vias 210, 214, 216, and 220 are under-etched, some dielectric substances of the dielectric layer 208 exist between the vias 210, 214, 216, and 220 and the metal layer 206. As an etchant, one which has a higher etching selectivity of the metal layer 206 with respect to the dielectric layer 208 is selected. In other words, the etchant etches the metal layer 206 at a substantially faster rate than the dielectric layer 208.
