Abstract: A condensation-curable resin composition which contains: (A) an organosilicon compound containing a structural unit (i) represented by the following formula (i) and a structural unit (ii) represented by the following formula (ii), having a SiOH group at both ends of the molecular chain, and having a weight average molecular weight of 10,000 or more and 10,000,000 or less; and (B) an organometallic compound having three or more condensation-reactive groups. In formula (i), each R1 is independently a hydrocarbon group having 1 to 8 carbon atoms. In formula (ii), each R2 is independently a hydrocarbon group having 1 to 8 carbon atoms.

Abstract: A blow-out air current guide used in an air current blow-out apparatus that has an air current blow-out portion that blows out an air current, which is supplied thereinto, in a predetermined blow-out direction. The blow-out air current guide includes an air current branching section and an air current deflecting section. The air current branching section causes a part of the air current that is blown out from the air current blow-out portion to branch as a branching air current, and the air current deflecting section substantially reverses the branching air current that is branched by the air current branching section and conducts this air current so that at least a part of the surface of the air current blow-out portion that does not face the air current flowing in the above-described predetermined blow-out direction in the air current blow-out portion is covered by the branching air current.

Abstract: A ventilator for buildings comprising a cylindrical main body which is open at both ends and provided with a plurality of seating members installed at attachment holes opened in the cylindrical circumferential wall of the main body. The seating members having surfaces conforming to the curvature of the cylindrical main body and also having perpendicular ends for holding the slats securely by screws.
