Abstract: An organic/inorganic composite is provided. The organic/inorganic composite comprises a silicon (Si) substrate formed with nanorods or nanoholes and three-dimensional networks of carbon nanotubes (CNTs) grown horizontally in parallel and suspended between the adjacent nanorods or inside the nanoholes. In the organic/inorganic composite, metal catalysts can be uniformly formed on the nanorods or inside the nanoholes, irrespective of the height of the nanorods or the depth of the nanoholes and the shape and aspect ratio of the nanorods or nanoholes. In addition, the carbon nanotubes grow in a three-dimensional network structure directly over the entire surface of the nanorods or the whole inner surface of the nanoholes and are directly connected to the base electrodes. With this configuration, the three-dimensional carbon nanotube networks are highly dense per unit volume, and the organic/inorganic composite is highly electrically conductive and has a large surface area.

Abstract: An electron beam irradiator capable of performing electron beam irradiation in a wide area at a high current density with a field emitter tip. The electron beam irradiator comprises: a vacuum chamber having a beam irradiation window formed longitudinally in an outer periphery of the vacuum chamber; a cathode placed centrally and longitudinally inside the vacuum chamber, and having a field emitter tip formed on the cathode, corresponding to the beam irradiation window; and a high voltage supply placed at one end of the vacuum chamber, and adapted to apply high voltage toward the cathode. The electron beam irradiation can be made in a wide area without using an electromagnet as well as in a high current density without using a heater such as a filament or an additional power supply, thereby to ensure a simplified structure as well as a reduced size.

Abstract: A data transmitting and receiving device, which transmits and receives ATM cells between the calculation processing modules is described. The ATM-based data transmitting and receiving device includes a transmitting means and a data receiving means. The data receiving means includes a memory controller for controlling storage of successively received ATM cells in corresponding cell buffers, and a memory controlled by it. The memory includes a linked cell buffer, a free cell buffer identifier queue, a receiving state table and a receiving completion state queue. Accordingly, a separate device (e.g., ASIC chip) can be used to transmit and receive ATM cells instead of the conventional calculation processing module so that the transmission efficiency of the ATM cell can be increased and the load of the calculation processing device can be reduced.

Abstract: A computer method and system capable of searching multiple heterogeneous datastores with heterogeneous data types by employing an object oriented data model to define a federated datastore object. The federated query object translates a generic query into the appropriate queries for each datastore, the federated datastore object acts as a virtual datastore for multiple heterogeneous datastores with the ability to map concepts between datastores, and the federated collection object represents results from a federated query in a hierarchy that maintains sub-grouping information from each datastore to allow accessing of results by datastore or as a single collection of results. The federated objects thus provide user applications with enhanced accessibility of different hierarchies of information, as well as more robust search capabilities.

Abstract: An ATM switching apparatus for a switch system is connected between a plurality of trunk connection units connected with a TDM network and an ATM connection unit connected with an ATM network. The ATM cell converting unit converts trunk data, inputted over the trunk connection units, to an ATM cell which is outputted to the ATM connection unit or converts an ATM cell, supplied from the ATM connection unit, to trunk data which is to be outputted to the trunk connection units. Accordingly, the ATM switching apparatus and method have an advantage of mutually operating the TDM network and the ATM network.
