    Abstract: A transmission or communication system, wherein plural individual elliptical orbits are so defined that an individual right ascension of a north-bound node is established with a designated angle. An artificial satellite is travels on a respective ones of the plural individual elliptical orbit and a group of artificial satellites arranged on respective ones of the plural individual elliptical orbits are used so that at least one of the artificial satellites having a communication system is always viewable within a pre-defined range of operational elevational angle in a zenith direction from a service area. The group of artificial satellites are on respective orbits obtained by combining an inclination angle and an eccentricity squared of the individual elliptical orbit so that a right ascension of north-bound node is a designated angle and a time period during which respective ones of the group of artificial satellites is viewable from ground is substantially identical.

  • Publication number: 20020111802
    Abstract: A lead consonant buffer stores a feature parameter preceding a lead voiced sound detected by a voiced sound detector as a feature parameter of a lead consonant. A matching processing unit performs matching processing of a feature parameter of a lead consonant stored in the lead consonant buffer with a feature parameter of a registered pattern. Hence, the matching processing unit can perform matching processing reflecting information on a lead consonant even when no lead consonant can be detected due to a noise.

  • Patent number: 5334837
    Abstract: Microanalytical methods and associated apparatus for detecting and quantifying organic compounds with very high sensitivity utilize reflected or refracted infrared radiation. By depositing microliter sized quantities of the sample containing solution in a drop-by-drop manner on a water-repellent thin film and rapidly evaporating a solvent, a coherently condensed concentric sample is produced having enhanced sample thickness. This sample is irradiated with infrared radiation which is either reflected or transmitted by the material underlying the thin film. Measuring the spectrum of the infrared radiation passing through the sample detects the existence and concentration of the organic compound. The water-repellent thin film may be provided with multiple small scale depressions, pinholes or zones of reduced surface tension for condensing the sample.
