Abstract: A ceramic chip antenna for use in ultra-high frequency communications. The ceramic chip antenna according to the present invention comprises a main body, first and second helical conductors, and a single power supply section for supplying power to the first and second helical conductors. The main body is produced by laminating a plurality of ceramic sheets made of a dielectric material. The first and second helical conductors are formed inside the main body by a screen-printing method. The first and second helical conductors have the same axis of helical rotation, as view from the power supply section.

Abstract: Disclosed are a system and a method for controlling a data transmission adapted for a grid computing and a computer readable recording medium of recording a process thereof, in which efficiently perform a grid computing using an ultrahigh speed communication network from an ultrahigh speed communication network in a non-congestion state to a communication network in a congestion state. TCP state information-providing section stores and provides TCP state information of a network. TCP state information-initializing section initializes TCP state information. Transmission mode-judging section judges a transmission mode of data to be transmitted according to the TCP state information. Packet processor generates and transmits traffic corresponding to each transmission mode classified according to the judgment result from transmission mode-judging section.

Abstract: A micro-robot for colonoscope with motor locomotion comprises an information detecting unit for obtaining information of the interior of the colon and a driving unit for generating its own locomotion and moving the information detecting unit without causing any damages to the walls of the colon.

Abstract: A high-sensitive micro cantilever sensor and a method for fabricating the same which is able to reduce size of a system greatly using a functional thin film has a structure in which an upper substrate comprising one or two piezoelectric cells including a cantilever, a piezoelectric layer formed on lower or upper surface of the cantilever, and electrodes formed on upper and lower surfaces of the piezoelectric layer is attached to a lower substrate including a cavity of an even depth by contacting the lower surface of the piezoelectric cell on the upper substrate with the cavity surface of the lower substrate.

Abstract: A catalyst of the formula (1) for the synthesis of alkylene carbonate by reacting alkylene oxide and carbon dioxide

Abstract: Disclosed herein is a process for purifying hirudin from a solution containing hirudin and other substances, characterized in that the process comprises a step of subjecting the solution to a metal ion affinity chromatography wherein copper ion (Cu.sup.++) is used as a metal ion and a phosphate buffer is used as an eluent.
