Abstract: A panel connected body includes a plurality of flat panels arranged in a matrix of m rows and n columns, where m?3 and n?3; and a plurality of row-direction connection portions and column-direction connection portions which connect together panels that are adjacent in a row direction and column direction, respectively. A first type row satisfying relationships D1?2L and Dy?Dy?1?2L and a second type row satisfying relationships Dn?2L and Dy?Dy+1+2L are alternately included, where Dy is a length along the column direction of the column-direction connection portions in a y-th column, and L is a thickness of the panels. The relationship E?WC?L is satisfied, where WC is a length along the column direction of the panels and E is a length along the column direction of the row-direction connection portions.

Abstract: An occlusion compound of 2-nitroxymethyl-6-chloropyridine with .beta.-cyclodextrin is disclosed herein as well as a process for preparing the occlusion compound thereof. The occlusion compound of the present invention has a molar ratio of 2-nitroxymethyl-6-chloropyridine to .beta.-cyclodextrin of between about 1:1 and about 3:1. The present occlusion compound is nonvolatile, thereby overcoming the problems associated with the volatility of the 2-nitroxymethyl-6-chloropyridine for pharmacuetical preparations. The process of the present invention is carried out by reacting 2-nitroxymethyl-6-chloropyridine with .beta.-cyclodextrin either by kneading both compounds together with a small amount of a solvent or by mixing both compounds in an appropriate solvent, such as water. The occlusion compound is then precipitated, separated and further purified by conventional methods.
