Title: Sorting device for radioactive waste and decontaminating device utilizing it
Inventor: HETA KATSUTOSHI
IPC: B07B4/02
Filed: 1990-09-26
Abstract: PURPOSE:To enable more complete sorting of abrasives and grinding dust by providing a plurality of sorting plates at each different height and with a constant tilting angle so as to have sufficient gravity sorting function for both of horizontal flow sorting and vertical flow sorting. CONSTITUTION:Radioactive waste consisting of abrasives and grinding dust to be sorted out, is thrown into the device from a hopper 1 and large sized waste is removed, for the first place, by a sieve 4. Then, guide plates 7a and 7b descend to drop the waste onto a sorting plate 5-1 from an end tip of the guide plate 7b. During the dropping down, the radioactive waste encounters with clean air flow supplied from a clean air feeder duct 2 toward an exhaust nozzle 10 via a lower opening of a partition plate 11. Light weighed grinding dust is transported toward the nozzle 10 via the lower opening of the partition plate 11 and heavy weighed abrasives climb down along the sorting plates 5-1 and, after encountering with a collision plate 6-1, climb down again toward a sorting plate 5-2. In the same manner, gravity sorting consisting of horizontal and vertical sorting is conducted at sorting plates 5-2 to 5-4 and finally the sorted waste is discharged out of a discharge hole 8.

Inventor: YOSHIOKA KAZUHIKO
IPC: B65H45/12
Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To favorably expand an air bag by forming a belt-like body extended in a direction crossing the cross direction of a vehicle so as to ride over a case opening part, and folding one end and the other end of this belt-like body so as to be housed in a case. SOLUTION: A belt-like body 20 is extended in a case opening part 3a in the fore and aft direction of a vehicle so as to ride over the case opening part 3a, and a ratio of a distance from the center in the fore and aft direction of the case opening part 3a to a front end 22a of the belt-like body 20 and a distance from the center to a rear end 24a is decided by positional setting of the predetermined position. Since both side parts of an air bag in the cross direction of the vehicle are folded inside of the air bag so as to form a bellows part 26 in both sides of the belt-like body 20, expansion of the air bag in both sides thereof is promoted. Expansion of the air bag housed in a case 3 in the folded condition in the cross direction of vehicle is promoted so as to delay the expansion of the air bag rearward of the vehicle. The air bag is thereby favorably expanded.
