Abstract: A low cost building is made of modular parts in the absence of special tools. Light-in-weight wall blocks having a facade of conventional appearance include a thick, insulating mixture of a cementitious material, polystyrene, and organic fiber aggregates capable of retaining water. The blocks have interlocking top and bottom surfaces so that they are easily stacked to form walls. A floor is built by spanning foundation beams with floor trusses that have a key along their respective tops and by sliding modular floor panels between contiguous floor trusses, each floor panel having opposite edges that slidingly engage the keys of the floor trusses. A roof is made in a similar manner by sliding modular roof panels between contiguous roof trusses. Tensioning rods are extended from a top surface of the walls to the building foundation to compress the walls.

Abstract: An image recording method is disclosed, which uses a substrate such as paper, a synthetic film, a metal plate, and an earthenware plate and an adhesive layer of a delayed-tack adhesive and activates the adhesive layer in accordance with image information, for example, by a step of endowing a tackiness to the adhesive layer by ejecting an organic solvent which renders the adhesive tacky from an ink jet printer cooperated with a computer in accordance with image information or a step of selectively heating the adhesive layer by a thermal printer to endow the adhesive layer with tackiness, and develops the latent image borne in the activated portion with powder selected from organic pigment powder, inorganic pigment powder, water-soluble dye powder, water-insoluble dye powder, metal powder, ceramics powder, plastics powder, magnetic powder, and microcapsules.
