Abstract: An object of the present invention is to provide a salt water thickener that uniformly (favorably) disperses ultrafine cellulose fibers even in a liquid containing a salt (electrolyte). The salt water thickener comprises ultrafine cellulose fibers and a water-soluble polymer and can thereby uniformly disperse the ultrafine cellulose fibers even in a liquid containing a salt. The salt water thickener of the present invention is uniformly dispersed even in a liquid containing a salt and therefore exerts a high viscosity. The salt water thickener of the present invention can also be used as an additive for a fluid. The salt water thickener of the present invention can be used for purposes, for example, subterranean formation processing.

Abstract: In an illumination system, a plurality of cameras and a plurality of illumination devices that are installed in a sidewalk where a person moves are connected to a control device through a network. Each of the plurality of cameras transmits detection information including a position and a movement direction of the person to the control device. The control device selects the illumination device that illuminates a front of the person in the movement direction of the person, from among the plurality of illumination devices, based on the detection information which is transmitted from each of the cameras, and further instructs the selected illumination device to light up.

Abstract: A camera is covered with a camera housing. The camera and the camera housing form a shooting window portion of a double structure having a clearance. A blowing tunnel communicated with the clearance of the shooting window portion is arranged on each of both sides of the shooting window portion. A blower sends a wind to the shooting window portion through the blowing tunnel. Further, a heater for heating the air sent to the shooting window portion is arranged in the blowing tunnel. Thus, dew condensation preventing ability can be improved by such a construction.
