Abstract: A liquid composition is formed into a coating layer state in which negative ions are steadily released. The liquid composition includes a finely powdered mineral that generates negative ions mixed with a binder liquid that is conductive and/or a binder liquid in which a conductive substance is dispersed.

Abstract: Longitudinal facing laid on a base between retainers at a prescribed spacing includes a central face plate, an inner riser along right and left edges of the face plate, an outer riser on an outer side of each inner riser, a drain channel formed between the inner and outer risers, an engaging portion at at least one of end and median portions of the outer riser and in resilient engagement with the retainers.

Abstract: A device for incorporating a layer member in a face construction of a building which is capable of employing a soft or flexible layer member as well as a rigid one, improving operation efficiency, ensuring safe operation at a height, and readily and precisely positioning and fixing a layer member in a face construction. The device comprises a base element, a connecting element mounted on the base element and a holding element mounted through the connecting element on the base element, the base element being adapted to be held on a supporting member of a building and hold a layer member in cooperation with the connecting and holding elements. The device may include a mounting member mounted on the holding element.

Abstract: A longitudinally assembled roof structure capable of exhibiting increased strength against a wind pressure and preventing rainwater from entering connection regions between the roof plates due to a capillary action and blowing of rainstorm against the connection regions. A plurality of the roof plates which are formed into a predetermined length in a longitudinal direction are longitudinally connected to each other, to thereby assemble the roof structure. The roof plates include a flat plate body, lateral rising connection sections provided on both lateral sides of the plate body, and longitudinal connection sections provided on both longitudinal ends of the plate body.

Abstract: A double roofing structure in which a water-proof drain plate is set on a backing. The rafter is fixed on the backing through the drain plate with a fixing member. Roof material or roof material holding member and inner layer material are placed and fixed on the rafter. A spacing layer communicating with an opening of the eaves is formed between the drain plate on the backing and the roof plate. The part communicating with the fixing member in the drain plate is formed with a projection.
