  • Publication number: 20040133805
    Abstract: A mark issuing server operated by a mark issuer manages mark information collectively. A terminal of a user sends an information providing request to an information providing server of an information provider, and issues a mark issuing request to the mark issuing server on the basis of the information providing request. The information providing server searches for information corresponding to the information providing request from the terminal of the user, and provides the terminal of the user with information including requested information and location information of the mark issuing server. The mark issuing server determines validity of information provided from the information providing server on the basis of the mark issuing request, and sends a mark to the terminal of the user when the validity is verified, and the terminal of the user displays the mark with the information provided from the information providing server.

  • Patent number: 6256293
    Abstract: Efficient methods for rerouting failed channels on to spare channels in a multichannel transmission system are described. One method uses a minimal amount of rerouting to reroute all the channels if one or two line cards fail. Another set of methods reroute up to two failed channels on to spare channels in the event of channel failures. With this method only the failed channels are rerouted. However the failed channels may have to be routed through a slightly larger, but minimal, number of additional hops than with the first method.

  • Patent number: 5441577
    Abstract: A method for producing a thin-film solar cell having a thin-film active layer on a graphite sheet substrate includes the steps of adhering two sheets of graphite together, forming semiconductor thin films serving as active layers on second main surfaces of the two sheets of graphite, and separating the two sheets of graphite from each other. In this structure, stress caused by a difference in expansion coefficients between the upper sheet and the semiconductor thin film is cancelled by stress caused by a difference in expansion coefficients between the lower sheet and the semiconductor thin film. Therefore, curvature of the substrates is prevented whereby subsequent process steps are easily carried out. In addition, the number of products per unit time is doubled, thereby increasing productivity.

  • Patent number: 5397400
    Abstract: A thin-film solar cell includes a thin active layer of high purity material having opposed front and rear surfaces for light-to-electricity conversion, a structure for supporting the thin active layer, and a rear electrode in contact with the rear surface of the active layer. The supporting structure includes a supporting substrate of a low purity material having opposed front and rear surfaces, on the front surface of which the rear surface of the active layer is disposed, and an insulating barrier layer interposed between the front surface of the supporting substrate and the rear surface of the active layer. The barrier layer prevents impurities in the supporting substrate from diffusing into the active layer. Since the supporting substrate comprises a low purity material, the quantity of the expensive high purity material can be reduced by reducing the thickness of the active layer, resulting in low production costs.

  • Patent number: 5360745
    Abstract: A thin-film solar cell includes a thin-film active layer with a p-n Junction and a heat-resistant substrate for mechanically supporting the active layer, which substrate is formed by a plasma coating method. In the plasma coating method, a source material of the substrate is melted with a high-temperature plasma and sprayed onto a base plate by a high-speed gas jet. Since the substrate formed by the plasma coating method is porous, even if an inexpensive material including a lot of impurities is used as a material of the substrate, the impurities are collected in pores of the substrate and never sprout out of the substrate breaking through the thin-film active layer.

  • Patent number: 5312761
    Abstract: The present invention relates to a method and an apparatus for measuring trace quantity of oxygen in a gas by reacting yellow phosphorus vapor and oxygen in a sample gas, and measuring the intensity of the light emitted by the reaction. Together with the sample gas, a constant amount of oxygen is continuously supplied to a reaction chamber so as to react with the yellow phosphorus vapor, and the intensity of the light emitted is measured. The oxygen concentration in the sample gas is determined from the difference between the value measured as above and the intensity of the light emitted by the reaction between the yellow phosphorus vapor and the added oxygen, or from the oxygen concentration obtained from the measured value and the concentration of the added oxygen.
