Title: Radio atm communication system
Inventor: MURATA TAIICHI
IPC: H04W84/12
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To improve transmission efficiency in radio section by temporarily using burst that is already allocated and a place where an empty cell (unused area) is included in the burst for cell transmission for another user. SOLUTION: A base station 40 manages a user channel that can be used by a terminal station 10-1. If it is detected that throughput is needed more than a user channel that is allocated to the station 10-1 when data is transferred, it is supervised whether the space of an ATM cell unit exists in a user channel that is used by another user. When there is space, a control channel notifies the station 10-1 of the other user channel slot position specification in a control channel and the station 10-1 recognizes the channel. After that, an ATM cell is multiplexed in the empty channel and sent, and the terminal 10-1 decides from the header information of the ATM cell, extracts the cell for its own station and receives it.

Abstract: PURPOSE:To feed a large-sized waste material to be ignited into a fluidized bed and continue a stable combustion of the waste material without cutting and breaking the same by a method wherein a height of each of air nozzles which are present in a bottom plate of the fluidized bed is alternately varied. CONSTITUTION:A fluidizing air 8 passes from an air box 5 through air nozzles 2 to cause a fluidized medium 4 to be flowed and then a fluidized bed is formed. A large-sized material 7 to be burned out may descend in the fluidized bed and reach onto the air nozzles 2.
