摘要:
A packet communication network is connected between a first external network and a second external network. The packet communication network includes a classifier, a parallel network that includes a plurality of physically or logically independent networks, and a multiplexing router. The classifier classifies a packet input from the first external network to one of the networks in the parallel network. Each of the networks in the parallel network transmits the packet to the multiplexing router. The multiplexing router multiplexes a packet received from the networks in the parallel network and outputs the multiplexed packet to the second external network.

Full-mesh WDM transmission units, each of which includes n number of interfaces and is capable of establishing a bidirectional full-mesh communication between all of the interfaces using wavelength paths based on a wavelength division multiplexing technique, are connected in a multistage tree-shaped structure by internetwork connection units through edge-packet transfer units connected to the respective interfaces. Therefore, it is possible to hold a direct communication between user terminals connected to the edge-packet transfer units of the same full-mesh WDM transmission unit, and to realize scalability by a multistage connection configuration.

A cost standard determination system and a cost standard calculation module are provided. The system enables the operational effort of a store operation by a store operator to be reflected in a commitment fee, thereby promoting the independence support of employees. A cost standard is a value serving as a basis for the calculation of a commitment fee paid by a store owner who owns the store to the store operator to whom the store operation is committed and is used as a reference value for evaluating the operation of the store by the store operator. The cost standard calculation module has five cost standard calculation processing functions corresponding to five cost attributes (controllable attribute, permittable attribute, controllable & permittable attribute, uncontrollable attribute, and uncontrollable-based-charge attribute) and calculates a proper cost standard for each of a plurality of accounts on the cost by selectively using the five cost standard calculation processing functions.
摘要:
A base member for use in manufacturing an ink jet recording head, which includes a supply port, an ejection outlet, a liquid flow path for directing liquid supplied from the supply port to the ejection outlet, and an ejection pressure generating element, disposed in the liquid flow path, for ejecting the liquid. The supply port is formed as a through-opening in a substrate on which the ejection pressure generation element is provided. The base member includes a recessed portion formed on the side of the substrate provided with the ejection pressure generation. The recessed portion extends from an edge of the supply port to a neighborhood of the ejection pressure generation element. A protection layer is provided at least on a portion of the substrate surface constituting the recessed portion.
摘要:
A data transmission and reception scheme capable of reducing required devices in the data transmission and reception system for an economical advantage, realizing the concurrent data delivery to a plurality of data reception devices, and allowing each one of a plurality of data reception devices to start the data reception at arbitrary timing. In a system for transmitting data from a data transmission device to unspecified many data reception devices that make asynchronous connections, the data transmission device carries out the repetitive transmission by repeating the operations of transmitting a prescribed amount of data to be transmitted by applying a prescribed signal conversion and then pausing the signal conversion processing for a prescribed period of time so as to provide a transmission pause state in the transmission signals which is to be utilized as a reception timing at each data repcetion device. At each data reception device, the transmission pause state in the transmission signals are detected at an arbitrary timing, and the reception of the transmission data is started by using the detected transmission pause state as the reception timing.
