Abstract

This air conditioner comprises a housing in which an air intake port and a blow-out port are respectively disposed on one surface and another surface opposite thereto which cross the horizontal surface. A heat exchanger and a cross flow fan are disposed in a row in the housing. The cross flow fan is driven so that the upper half side thereof rotates in a direction from the heat exchanger toward the blow-out port. Bending of an in-machine flow passage which is an air flow passage inside the housing is indispensable for a blowing operation by the rotation of the cross flow fan. In this air conditioner, an air flow adjustment part is provided to achieve the bending of the in-machine flow passage, an air flow going toward the cross flow fan from oblique lower side is generated on the air intake port side, and an air flow going from the cross flow fan toward the oblique lower side is generated on the blow-out port side.

A road embankment 10A is configured by layering a plurality of crushed, surface compacted soil layers 12A. The crushed, surface compacted soil layers 12A are formed by adding a solidifying agent to sediment from which non-soil material has been removed, mixing and curing the result, then crushing the resulting initial solidified soil manifesting a prescribed strength before complete solidification to a prescribed particle diameter so as to form embankment material. The embankment material is scattered and leveled, compacted, cured after compaction, and then completely solidified. Soil deposited by tsunamis or dredged soil that is dredged from sedimentation deposited on the bottom of harbors, rivers, canals, and the like are used as the sediment.

Abstract

A bank (12) is formed into a trapezoid cross-sectional shape by an embankment, in order to provide a seawall (10) having sufficient erosion resistance to overflow caused by a tsunami, and whereby the time until the seawall is destroyed or collapses even if the tsunami has overflowed the seawall is increased, thereby reducing the effects of natural disasters. A concrete wall section (14) is formed along a slope (18A) in the bank (12), said slope facing the water side (ocean side, river side). All of the top (16) and land-side slope (18B) of the bank (12), except the concrete wall section (14), is covered in a reinforcing layer (20) comprising crushed/compaction-rolled soil. The reinforcing layer (20) comprising crushed/compaction-rolled soil is provided by spreading, leveling, compaction rolling, and curing embankment soil having a variety of particle diameters and produced by an initial solidification soil being crushed to no more than a prescribed particle diameter, said initial solidification soil comprising a solidification material added to sedimentary gravel that is then agitated, mixed, and cured, and exhibiting a prescribed strength.

Abstract

[PROBLEMS] A roll-up shutter having excellent fire protection performance, capable of being quickly opened and closed, and capable of using a large-sized shutter curtain. [MEANS FOR SOLVING PROBLEMS] Each slat (18) of the shutter curtain (12) of the roll-up shutter (10) is an aluminum alloy profile member having a predetermined cross-sectional shape. The profile member has a pair of side face walls, an upper edge section for connecting together side edge sections on the upper side of the pair of side face walls, and a lower edge section for connecting together side end edges on the lower side of the pair of side face walls. A labyrinth (50) is formed by and between the lower edge section (42) of the upper of two vertically adjacent slats and the upper edge section (40) of the lower. Also, when vertically two adjacent slats have different amounts of bending deformation caused by a temperature difference between both side faces of each slat, no gap is formed between the two slats because the lower edge section of the upper slat and the upper edge section of the lower slat are engaged with each other.

Abstract

[PROBLEMS] To provide an obstacle detector of an electric shutter exhibiting high sensitivity and high operation reliability and not permitting blow-through of flame from one side to the other side of the shutter upon occurrence of a fire, and to provide an electric shutter equipped with such an obstacle detector. [MEANS FOR SOLVING PROBLEMS] The obstacle detector comprises a flexible edge member (24) fixed to the bottom edge of a shutter curtain (12) and extending substantially over the entire length thereof. In the vicinity of one end of the edge member, a laser beam projector (34) projecting a laser beam in the longitudinal direction of the edge member through a hollow space (30) defined by the edge member is arranged, and a photosensor (40) for receiving that laser beam is arranged in the vicinity of the other end of the edge member. When the edge member is deformed elastically by external force and crushed, the laser beam is intercepted by the edge member and prevented from entering the photosensor. The edge member is made of a flame retardant elastomer material.
