摘要： PROBLEM TO BE SOLVED: To make performable a sterilization process with high sterilizing quality using electron beams without waste even in small enterprises by picking up materials to be sterilized from plural shippers, collectively sterilizing the materials to be sterilized by electron beams, storing the same in a shipping part, and delivering the materials to be sterilized to plural distribution destinations according to the shipper's instruction. SOLUTION: Materials to be sterilized are picked up from plural enterprises as shipper 1, and stored in a carry-in part 3 of a joint sterilization physical circulating center 2. The materials to be sterilized stored in the carry-in part 3 are sequentially carried in a sterilizing processing part 4 for sterilizing by electron beams to sterilize by radiation with the electron beans. The material to be sterilized which has been sterized by a sterilization processing part 4 are stored in a forwarding part 5. The materials to be sterilized stored in the forwarding part 5 are sorted at need, to be distributed to each distribution destination 6 according to a shipper's instruction. Thus, the respective shippers, that is, the respective enterprises have not to posses an electron beam sterilized, no problem is caused in sterilization, and electron beam sterilization processing with high sterilizing quantity is applied to the materials to be sterilized.

摘要： PROBLEM TO BE SOLVED: To prolong a device life and ensure safety even under severe working conditions, by providing a female part constituting a part of a clutch, a male part capable of separating from and fitting to the female part, a rotation rod having the female part or the male part at a tip thereof, and a moving mechanism which moves a drive source connected to the rotation rod forward to or backward from the female part. SOLUTION: When opening adjustment is needed, a slider 69 moves forward by a hydraulic cylinder 71, and a rotation rod 57 supported by the slider 69 moves forward to an opening adjustment mechanism 9 of a nozzle 7 of a bottom surface of a ladle 1. At this time, when there is an error in an installation position of the ladle 1, a position of a female part 53 of a clutch 51 is displaced. However, when the forward moving is continued, a male part 55 of the clutch 51 at a tip of the rotation rod 57 comes into contact with an inside of a bell-mouthed guide 143, is introduced toward the female part 53 along the guide 143, and comes into contact with the female part 53. Normally, since a hydraulic motor 63 as a drive source can keep backward, it can avoid exposure to high temperature atmosphere. Further, the hydraulic motor 63 is not adversely affected by sparks from molten steel delivered from the nozzle 7. Accordingly, a device life can be prolonged.

摘要： PROBLEM TO BE SOLVED: To effectively utilize waste plastics as inexpensive fuel and to reduce the production cost by providing a firing furnace for firing raw ores, such as lime stone and dolomite, with a waste plastic blowing lance having a specific lance diameter. SOLUTION: The firing furnace is provided with the waste plastic blowing lance 6 having a lance diameter D1 satisfying the equation. In the equation, D1 is the diameter of the waste plastic blowing lance; Fp is a waste plastic supply rate (kg/sec); t is a waste plastic firing time (sec); θ is an angle of repose of the raw ores ( deg.); Pp is a waste plastic bulk density (kg/cm ). Namely, the slope of the angle of repose (θ) on which the raw ores glide down diagonally along a direction toward the center from the peripheral edge is formed at the front end portion of the waste plastic blowing lance 6 entering in a raw ores packed bed 5 and a gap 7 is formed above this slope. The gaps among the adjacent lime particles and the spacing at the bottom of the lance in addition to this gap part also contributed to the combustion of the waste plastic. The volume twice the volume of this gap part is used as the gap part volume effective for combustion.
