    摘要: A communication control system using an ATM network and constructed by a small number of virtual connections. Fixed or semi-fixed virtual connection connect each user interface and a corresponding connectionless service processor and interconnect the connectionless service processors. A data packet received from a user terminal is converted into an ATM cell by the user interface and delivered to the connectionless service processor through the virtual connection. In the connectionless service processor, an ATM cell is transferred into a virtual connection located in the direction in which the destination user interface is provided to thereby carry out routine to the ATM cell.

    摘要: An electric melting furnace for vitrifying waste, having a melting tank having walls of refractory bricks, the melting tank being provided at the upper portion thereof with a supply port for a glass additive and waste and at the bottom portion thereof with a discharge port for molten glass containing the waste; at least a pair of side electrodes horizontally provided on opposite side walls of the melting tank; and at least one central electrode having a polarity opposite to that of the side electrodes, the central electrode being horizontally positioned in the interior of the melting tank at substantially the middle portion between the side electrodes. By such melting furnace construction, as described above, the heating current selectively flows through between the side electrodes and the central electrode, and does not flow electrically conductive substances deposited on the furnace bottom.
