Abstract:
Provided are an opto-electric bus module and a method of manufacturing the opto-electric bus module. The opto-electric bus module includes an opto-electric interconnection unit where a concave-shaped micro structure is formed on a lower surface of a polymer structure and an optical bench where a convex-shaped micro structure is formed in a position corresponding to the concave-shaped micro structure, at least one second electric interconnection for electric connection with a semiconductor chip is formed, and the semiconductor chip and an opto-electric device can be mounted. Thus, automatic, efficient, high-speed, and high-integration optical communication and electric communication between multi-chips can be completed at the same time by using the opto-bus module which provides low-speed electric communication while manually maintaining solid optical coupling.
Abstract:
A digital roulette game provision system that has different betting methods is provided, with the system comprising a plurality of terminals, with each terminal being designed to provide a digitally processed digital roulette game that has different betting methods, to receive the bills and coins entered by a user who selectively uses a digital roulette game that has different betting methods, to display the bills and coins in a form of betting money and chips, to receive statistic information such as betting information, roulette information, probability information, etc. previously stored in a statistic server, to display the above information on a screen, to transmit statistic information such as betting information, roulette information, probability information, etc. to a statistic server through a network based on the operation of a user who selectively uses a digital roulette game that has different betting methods, to select a winning number using a digitally processed digital wheel and an electronic ball, to display a winning state, a payoff rate, dividends and a process result on a screen in accordance with the bet placed by each user with respect to a digital roulette game that has different betting methods, to sum betting money and dividends and provide the same to the user who won a certain amount of dividends as a result of the digital roulette game, and to change the summed money into cash based on a user's selection.

Abstract:
The present invention relates to a sodium-intervened superconductor and its manufacturing method and more particularly, to the sodium-intervened superconductor expressed by the following Formula 1 and its manufacturing method, wherein the superconductor, prepared from a stoichiometric mixture of Y.sub.2 O.sub.3, NaCuO.sub.2, BaCuO.sub.2, Ln.sub.2 O.sub.3 (Ln: lanthanide ion) and CuO under the atmosphere of oxygen, has some advantages in that a) through the use of NaCuO.sub.2, a ternary oxide, as a reactant, the formation of impurities and sodium evaporation may be prevent, and b) through partial substitution of a divalent barium by a trivalent lanthanide group ion, the superconductor is stable in air with a higher critical current density and critical temperature.Formula 1(Na.sub.1-x Y.sub.x)(Ba.sub.1-y Ln.sub.y).sub.2 Cu.sub.3 O.sub.6+.delta.wherein, Ln is a trivalent lanthanide ion other than Ce and Pr; 0.1
Abstract:
An optical pickup device having a simple structure due to many less components is disclosed. A laser beam generated in a laser diode is transformed into a parallel laser beam. The laser beam is irradiated onto a polarization beam splitter including a prism having a partially reflection coated layer on an oblique surface thereof, a mirror and a polarization beam splitting plane, the prism being formed at a first corner of a rectangle of a hexahedron, the mirror being formed at a second corner opposing the first corner, the polarization beam splitting plane being formed between the prism and the mirror on a line parallel with the partially reflecting coated layer, the line passing through a third corner, and the prism, the mirror and the polarization beam splitting plane being formed integrally in the hexahedron. The laser beam is irradiated onto a disc and the reflected light is split into a first polarization component and a second polarization component. The first and second polarization components are detected in a photo-detector to generate data signal. Compact optical pickup device can be manufactured. Also, the assembling work therefor is simplified to enhance the reliability of the optical pickup device.
