Abstract: An artificial snowseed in the form of granules of a super water-absorbing polymer already coated with a fluorine-containing material and/or a silicone oil. The granules can retain the original spherical form after absorption of water without sticking to each other. Further the present invention provides a method for making artificial snow comprising freezing the above artificial snowseed after absorption of water.

Abstract: A system for utilizing exhaust heat and the like from an internal combustion engine, in which at least a part of the internal combustion engine is immersed in a heat transfer medium contained in a vessel provided at the top thereof with an opening. The internal combustion engine is supported by a member secured to the opening of the vessel, an anti-vibration member or members are interposed between the member and the vessel and/or an anti-vibration casing covering the support member is provided, thereby facilitating the anti-vibration and sound arresting measures.

Abstract: A horizontal force resisting building structure having a steel building framework, a bearing wall member being placed outside the building framework so as to face a suitable structure plane of the framework, and an attachment for attaching the wall member to the framework. The attachment has less resistance to plastic deformation than the wall member, and may include a bracket and a connector for connecting the bracket to the wall member.

Abstract: A module for a modular building structure comprises a frame including a horizontal base member of a rectangular shape and four vertical corner posts of the same length secured at their lower ends to the four corners of the base member. A first wall member is attached to two adjacent ones of the four corner posts. A second wall member is attached to one of the two adjacent corner posts and the corner post disposed in diagonal relation to the other of the two adjacent corner posts.
