摘要:
At a time of transmitting a packet from a node connected with one logical network to another logical network, a control message is transmitted to a network interconnection apparatus connecting the one logical network and the another logical network, when a new node is activated beyond the network interconnection apparatus, the control message including information for a registration in the network interconnection apparatus of a correspondence relationship between a first virtual path to be used in receiving a packet from the one logical network and a second virtual path to be used in transmitting the packet to the another logical network.

A method of controlling data transmission in the ATM network which establishes simple modes of a network control for a case in which a plurality of cell loss priority levels are involved within the cells of a single virtual channel. The method includes the steps of declaring the traffic characteristics for either the loss intolerable cells only, or the loss intolerable cells and the loss tolerable cells separately, and carrying out at the network a connection admission control by estimating a cell loss rate on a basis of the declared traffic characteristics, such that the cell loss rate for either the loss intolerable cells only, or the loss intolerable cells and the loss tolerable cells separately in the multiplexed virtual channels is secured by the network on a basis of the estimated cell loss rate.

A thermal transfer recording apparatus is disclosed and includes a recording medium sheet formed of a plastic film material having numerous minute voids therein, and a thermal recording sheet formed of a heat resistive base sheet with opposing surfaces and a thermal transfer layer coated onto one of the opposing surfaces of the base sheet. The thermal transfer layer comprises an ink material containing a binder material and being transferable to the recording medium sheet, and particles which are solid at room temperature and are mixed into the transfer layer in order to form minute protrusions on a surface of the thermal transfer layer. The apparatus also includes a heater for raising the temperature of the thermal transfer layer in a controlled manner so as to decrease the viscosity of the thermal transfer layer. The recording medium sheet can, alternatively, be provided with a coated layer coated onto the surface of the plastic film and comprises a coated layer material, and particles which are solid at room temperature and have a diameter greater than the thickness of the coated layer material, so as to provide a roughened surface to the coated layer.

摘要:
A scheme for controlling a congestion in the communication network, capable of realizing a recovery from the congestion state by the operation at the lower layer level for the communication data transfer alone, without relying on the upper layer protocol to be defined at the terminals. In a communication network including first and second node systems, a flow of communication data transmitted from the first node system to the second node system is monitored and regulated by using a monitoring parameter. On the other hand, an occurrence of congestion in the second node system is detected according to communication data transmitted from the second node system, and the monitoring parameter used in monitoring and regulating the flow of communication data is changed according to a detection of the occurrence of congestion in the second node system.
摘要:
An electroosmotic ink printer head comprising a dielectric support having a surface defined by longitudinal front and rear edges and a pair of transverse edges. A plurality of first electrodes is successively arranged on said surface extending rearward from the front side of the support. A porous member is provided to overlie the first electrodes in contact with said surface. On the porous member is a second, liquid-permeable electrode on which is provided a means for supplying ink thereto to allow it to permeate therethrough to the porous member. A third electrode is located adjacent to each outermost one of the first electrodes and to the longitudinal front edge. A potential is applied to the third electrode with respect to the second electrode to cause the ink in the porous member to electroosmotically move in a direction from the third electrode to the second electrode. The ink which might wet the front edge of the support is pulled rearward by the electroosmotic movement.
