    • PROBLEM TO BE SOLVED: To increase a water collecting capability at the time of a heavy rain and to prevent the cracking of a cover outer edge by providing a notch section (stream port) on a top face closed type street gutter block, and fitting a cover having a grating at an end section. SOLUTION: A street gutter cover 2 fixed with a grating member 7 at an end section is inserted to the lock step section 1a of a gutter body 1 so that the rainwater falling on a road surface efficiently flows to a drain hole 4 from the grating member 7 and a notch section 10 provided on the gutter body 1 and a road D is not flooded even at the time of a heavy rain. The grating member 7 provided at the end section of the gutter cover 2 serves as a reinforcing material, and the cover 2 is prevented from being broken or cracked even when it is applied with loads by the travel of automobiles. The cover 2 can be simply removed when it is opened or closed for cleaning the drain hole 4, thereby the execution of the gutter cover 2 can be conducted efficiently.

    • PROBLEM TO BE SOLVED: To improve the cleanness of discharged air by storing and arranging multiple reaction bodies where photocatalystic materials are disposed on the front surface in the hollow part of a hollow vessel and generating an air stream inside the vessel while irradiating a light from a light source and permitting the reaction bodies to be brought into contact with air while they are floated and moved. SOLUTION: When an air purifying device 1 is operated, outer air is supplied to the center part 13 of the hollow vessel from a blow fan 20 through an air stream introducing part 16 while irradiating the reaction bodies 18 with the light from the light source 19 at first. Then a spiral stream is generated in the hollow part 13 by the air and the bodies 18 are intensely moved. That is, a light irradiation is uniformly executed to the multiple reaction bodies 18 by floating and moving the bodies 18 in the hollow part 13 by the irradiation of the light from the source 19. Then positions facing the light source 19 in the bodies 18 are changed during the continuous light irradiation from the source 19, most of the total area of the front surface are irradiated with the light in the bodies so that a purifying effect by a photocatalystic function is obtained on nearly the whole front surface of the bodies 18.

    • PROBLEM TO BE SOLVED: To improve the strength and rainwater draining performance and reduce the noise by the traveling load of an automobile by bolting a gutter lid formed of a reinforced concrete board and a grating member fixed to the end thereof to a gutter body. SOLUTION: This gutter lid 4 is formed of a reinforced concrete board and grating members 5 fixed to both ends thereof. The grating member 5 is formed of a punching metal having a number of pore parts 7, and fixed by burying anchor bars 11 fixed to the side surface in the reinforced concrete board. The gutter lid 4 is placed on the locking stepped part of an opening formed in a gutter body, and an insert bolt 9 is screwed to an insert member 8 buried in the gutter body through a mount par 10 formed on the grating member 5 to fix the gutter lid 4. An insert nut may be buried instead of the anchor bar 11 to fix the grating member 5. According to this, the strength and rainwater draining performance of the gutter lid 4 can be improved to reduce the noise by the traveling load of an automobile.
