  • Patent number: 7803545
    Abstract: Heteroduplex band resolution is found to be improved by modifying the induced heteroduplex generator (IHG) molecule such that the identifier is spaced apart from the nucleotide position immediately adjacent to the site of the polymorphism which is to be genotyped. Unexpectedly, it is found that, when such modified IHG molecules are used, the resolution of the induced heteroduplexes is significantly improved.

  • Patent number: 7797016
    Abstract: A method for mobile communication includes arranging a plurality of access points in a wireless local area network (WLAN) to communicate over the air with a mobile station using a common basic service set identification (BSSID) for all the access points. Upon receiving at one or more of the access points an uplink signal transmitted over the WLAN by the mobile station using the common BSSID, messages are sent and received over a communication medium linking the access points in order to select one of the access points to respond to the uplink signal. The selected one of the access points transmits a response to the mobile station.

  • Patent number: 7792176
    Abstract: A narrow-band laser device for exposure apparatus that allows to reduce damage to, and to hence extend the life of, optical elements such as chamber windows, output coupling mirrors or the like. A ring resonator is provided in an amplification stage laser of the narrow-band laser device for exposure apparatus that comprises an oscillation stage laser and an amplification stage laser. An OC, a high reflection mirror and a high reflection mirror are arranged to be offset, for instance, relative to a longitudinal direction axis of discharge electrodes. As a result, the beam width of laser light injected through the OC of the amplification stage laser becomes wider as the beam shifts inside the ring resonator, in each round trip within the ring resonator. The energy density of laser light in the optical elements of the amplification stage laser becomes reduced thereby, thus prolonging the life of the optical elements.

  • Patent number: 7767020
    Abstract: A method for manufacturing a single crystal semiconductor, in which, in a process of pulling up the single crystal semiconductor from melt for growing it, an impurity is incorporated more uniformly into the single crystal semiconductor so that a variation in impurity concentration across the semiconductor wafer surface can be reduced, and thus, the planarity of the wafer can be improved. In the process of pulling-up the single crystal semiconductor (6), fluctuation in a pulling-up speed is controlled, whereby the variation in concentration of the impurity in the single crystal semiconductor (6) is reduced. Especially, a width of speed fluctuation (?V) in 10 seconds is adjusted to less than 0.025 mm/min. Furthermore, in carrying out the control for adjusting the pulling-up speed such that a diameter of the single crystal semiconductor (6) becomes a desired diameter, a magnetic field having strength of 1,500 gauss or more is applied to the melt (5).

  • Patent number: 7718792
    Abstract: A method to stereospecifically prepare a steroidal sapogenin or a derivative thereof by reducing a 3-keto,5?-H steroidal sapogenin with a hindered organoborane or an organo-aluminium hydride. A 3?-hydroxy,5?-H steroidal sapogenin or derivative thereof may be prepared by reducing the 3-keto,5?-H steroidal sapogenin using as reducing agent a relatively highly hindered organoborane reagent or by SN 2 inversion of a 3?-hydroxy,5?-H steroidal sapogenin or derivative thereof.

The dipoles may be arranged as a dipole box around a central region, typically in a generally circular or square configuration. Further elements may be placed in the dipole box or in the gaps between dipole boxes. The antenna may be a single-band antenna, or a multi-band antenna with the further elements operating in a different frequency band to the dipole boxes. The further elements may be concentric dipole boxes. The invention is particularly suited for use in a cellular base station panel antenna. A novel coaxial to microstrip transition is also described.
