  • Publication number: 20110254744
    Abstract: Disclosed is a portable wireless apparatus that can be miniaturized and that can achieve high antenna performance even when the antenna and circuit board overlap in the vertical direction. In this apparatus, a second case (102) is mounted so as to be slidable with respect to a first case (101). An antenna (106) is provided on the second case (102). A circuit board (104) is provided on the first case (101) and has a slit (108) that extends in the direction intersecting the sliding direction, at the boundary of a region (r1) including a region opposite the antenna (106) in the vertical direction and a region (r2) other than this region (r1), when the first case (101) and second case (102) are overlapping and closed.

  • Publication number: 20110169712
    Abstract: When three or more antennas and a plurality of wireless circuits using wireless frequency bands near to each other are installed on a cabinet whose size is limited, degradation of characteristic caused by electromagnetic coupling between antennas is suppressed. When a first antenna 21 and a second antenna 22 are connected to a first wireless circuit 31, a third antenna 23 is connected to a second wireless circuit 32, and an operation frequency band of the second wireless circuit 32 is near in a higher band than an operation frequency band of the first wireless circuit 31, a feeding point 23a of the third antenna is placed at a position nearer to a feeding point 21a of the first antenna than the feeding point 22a of the second antenna.

  • Publication number: 20110037676
    Abstract: To make it possible to suppress degradation in characteristics by electromagnetic coupling between plurality of antennas and to cope with miniaturization of a housing even if a plurality of radio circuits operate simultaneously. In a mobile radio apparatus in which a circuit board 102, a first antenna 111 and a second antenna 112 are mounted in a housing 101, a first radio section 121 and a second radio section 122 are mounted in the circuit board 102 and the first radio section 121 and the second radio section 122 can operate simultaneously, a reactance element 131 for influencing an operating frequency of the first radio section 121 or the second radio section 122 is disposed in at least one of the first antenna 111 and the second antenna 112 when an electric length of the circuit board 102 is configured to be shorter than one-fourth a wavelength of at least one of the operating frequencies of the first radio section 121 and the second radio section 122.

  • Publication number: 20100240424
    Abstract: There is adopted an enclosure dipole antenna structure including antenna elements respectively provided in a lower enclosure and an upper enclosure. There is also adopted a structure in which the lower structure and the upper structure are rotatably joined together along two axes of hinges. The enclosures thereby become openable and closable in two directions including a vertical direction and a horizontal direction. There can be implemented high antenna performance without use of an external antenna even regardless of whether the enclosures are opened in the vertical direction or the horizontal direction. A feeding section and a connection section are separated from each other by a distance of 1/20 or more of a wavelength corresponding to an operating frequency. Power can well be fed to the antenna elements.

  • Patent number: 5559333
    Abstract: A non-dispersive infrared analyzer and method for analyzing a concentration in a gas utilizes an infrared light source and a cell configured to have a gas flow therethrough. The cell also has an infrared light passage through which a sample gas stream and an infrared light beam can travel. A sector has at least two filters for filtering infrared light, and is provided with the apparatus. The sector alternately inserts the at least two filters into the infrared beam. A detector detects wavelengths of the infrared light beam which corresponds to an absorption band of the gas to be measured, and a second wavelength which corresponds to an absorption band of the preselected reference gas. The detector receives the infrared light beam after the light beam has traveled through the sample cell.

  • Patent number: 5334463
    Abstract: A hybrid fuel cell system including a fuel cell for generating electric power by reacting fuel gas and oxidant gas, current restricting structure for restricting an output current of the fuel cell, a storage cell connected parallel to a series circuit comprising the fuel cell and the current restricting structure for helping the fuel cell to supply electric power to an external load, external load fluctuation detecting structure for detecting a fluctuation in the current demanded by the external load and current limitation adjusting structure for following the fluctuation in the current demanded by the external load by changing the restriction of the output current of the fuel cell which is made by the current restricting structure, with the passage of time.

  • Patent number: 5271894
    Abstract: In a chemiluminescent analyzer for measuring a concentration of an object gas in a sample gas by mixing the sample gas with 5 a reaction gas and measuring light generated in a chemical reaction between the object gas and the reaction gas, the two gases flow through a double tube composed of an outer tube and an inner tube, and are mixed at the end of the tubes. The end of the inner tube is closed, and one or more outlets are provided at the side wall of the inner tube near the closed end. The flow of the gas coming out of the inner tube through the outlet or outlets crosses the flow of the gas in the outer tube, which enhances the mixture of the two gases and increases the chance of reaction between the object gas and the reaction gas.
