  • Publication number: 20100113621
    Abstract: A water-in-oil (W/O) emulsion which is stable even with a high water content is provided. The water-in-oil (W/O) emulsion is obtained by a three-phase emulsification using a reverse vesicle of an amphiphilic compound as an emulsifier. As the amphiphilic compound, a sucrose fatty acid ester is preferable, and a sucrose fatty acid ester with an HLB value of 6-12 is more preferable. The reverse vesicle can be prepared by mixing an amphiphilic compound with a non-polar solvent. The water-in-oil (W/O) emulsion can be formed by using the prepared mixture containing the reverse vesicle as an oil phase and adding water thereto for emulsification. As the non-polar solvent, an alicyclic hydrocarbon solvent such as cyclohexane is preferable. The reverse vesicle preferably has a particle diameter of not more than 1 ?m.

  • Patent number: 7706249
    Abstract: A method and apparatus is provided for transmitting an orthogonal frequency domain multiple access (OFDMA) signal including a synchronization channel signal transmitted within a localized portion of a bandwidth of the OFDMA signal (818), the synchronization channel signal having predetermined time domain symmetry within the localized portion of the bandwidth (816). The synchronization channel signal enables an initial acquisition and cell search method with low computational load which provides OFDMA symbol timing detection and frequency error detection by differential processing of sequence elements of the synchronization channel signal (1112) and frame boundary detection and cell specific information detection (1114) in an OFDMA system supporting multiple system bandwidths, both synchronized and un-synchronized systems, a large cell index and an OFDMA symbol structure with both short and long cyclic prefix length.

  • Publication number: 20100032127
    Abstract: In a mold for casting a billet with a curved type continuous casting apparatus, D0 (m) is an inner diameter at a lower mold edge and R0 (m) is a curvature radius of an outer curvature side at the lower mold edge. When a rate of change Tp (%/m) in mold inner diameter per unit length along a casting direction is Tp=(1/D0)×(dD/dx)×100 (%/m), and when a rate of change Rp (%/m) in curvature radius of an outer curvature side per unit length along the casting direction is Rp=(1/R0)×(dR/dx)×100 (%/m), the rate of change Tp in mold inner diameter and the rate of change Rp in curvature radius satisfy a relationship expressed Rp=(Tp/2)×(D0/R0), where D is a mold inner diameter at a distance x away from an upper mold edge and R in Formula 2 is a curvature radius of the outer curvature side at the distance x.

  • Publication number: 20100032129
    Abstract: A method for continuously casting a billet with a small cross section in which a curved type or vertical type continuous casting machine is used while oscillating the mold upward and downward is characterized in that the casting machine is provided with a mechanism for withdrawing speed oscillation. The mechanism has structural play in the directions of driving and reverse driving in such a manner that the amount of a play-incurred displacement from the neutral position of the structural play in the direction of billet driving or reverse driving is ±2 to ±30 mm in the direction of driving on the pinch roll circumferential length equivalent basis. The mechanism produces a returning force toward the neutral position and operational parameters such as the billet length, the specific amount of secondary cooling water, the casting speed as well as the oscillation amplitude and frequency are optimized.

  • Publication number: 20100025004
    Abstract: Continuously casting a billet with a small cross section by pouring molten steel into a mold using a cylindrical immersion nozzle is characterized by measuring the molten steel level in the mold using an eddy current sensor. The level is controlled based on the thus-measured value, motion of steel in the mold is adjusted by electromagnetic stirring, a cooling zone during the final period of solidification is disposed within a certain region ranging from the meniscus to the specific site, and casting speed is adjusted so that the region in which the solid phase ratio at the billet center is 0.3-0.99 may be included in the cooling zone during the final period of solidification. The secondary cooling water amount and the billet surface temperature at the entrance to the cooling zone the density of cooling water in the cooling zone during the final period of solidification are optimized.

  • Publication number: 20090060003
    Abstract: A cellular communication system employs a plurality of bandwidths. The cellular communication system comprises a plurality of base stations (101, 103) each of which transmits a reference signal comprising a Generalised Chirp-Like, GCL, sequence. The length of the GCL sequence is dependent on the bandwidth employed by the base station (101, 103). A sequence generator (105) provides a first subset of GCL sequences for a first bandwidth selected from a set of possible GCL sequences for the first bandwidth in response to properties of a sub-sequence of GCL sequences. The sub-sequence has a length corresponding to a different bandwidth. Sequence processors (107, 109) select GCL sequences for base stations (101, 103) employing the first bandwidth from the first subset of GCL sequences. The invention exploits characteristics of GCL sequences to enable, facilitate or improve multiple bandwidth operation.
