| 20080318606 | WIRELESS TRANSMISSION METHOD, AND WIRELESS TRANSMITTER AND WIRELESS RECEIVER - A wireless transmitter controls the number of transmission beams to be formed for transmitting a data stream depending on the number of data streams to be transmitted, and a wireless receiver selectively receives any one or more of the transmission beam from the transmission beams. In this manner, by changing the number of transmission beams (the original number of beams selectable on the receiving side) to be formed depending on the number of transmitting data streams, high throughput characteristics by a low interbeam correlation at the time of the multistream transmission and a large directional gain at the time of a single stream may be achieved. | 12-25-2008 |
| 20090016461 | BASE STATION AND MIMO-OFDM COMMUNICATION METHOD THEREOF - When performing communication with a mobile station using MIMO-OFDM communication, a base station uses multiple input multiple output (MIMO) communication, which is multiple data stream transmission, to transmit data and pilot signals in a case where the communication environment of the mobile station is good, or uses single input multiple output (SIMO) communication, which is single data stream transmission, in a case where the communication environment of the mobile station is poor. When performing that SIMO communication, the base station performs control so that pilot signals from a specified cell that are used in channel estimation in single data stream transmission and pilot signals from adjacent cells that are used in channel estimation in single data stream transmission do not overlap in the frequency direction and/or time axis direction. | 01-15-2009 |
| 20090048477 | Hydrocracking Catalyst, and Method for Production of Fuel Base Material - A hydrocracking catalyst that solves the above-described problem comprises a carrier containing ultra-stable Y-type zeolite obtained by the ultrastabilization of NaY-type zeolite and a metal from group VIII of the Periodic Table supported on this carrier, and is characterized in that the NaY-type zeolite has a peak in its X-ray diffraction pattern in the range of 2θ=28.0° to 28.5° and 2θ=15.0° to 16.0°, and the intensity ratio I | 02-19-2009 |
| 20090159490 | METHOD OF HYDROGENOLYSIS OF WAX AND PROCESS FOR PRODUCING FUEL BASE - The hydrocracking method of wax of the invention is a hydrocracking process wherein crude wax is subjected to hydrocracking and the untreated wax fraction that is produced after the hydrocracking is re-supplied for hydrocracking, and wherein hydrocracking of the mixture of the crude wax and untreated wax fraction is carried out in such a manner for a conversion ratio of 50-85% by mass from the wax fraction with a boiling point of 360° C. or above to the light fraction with a boiling point of below 360° C. in the presence of a hydrocracking catalyst. It is thereby possible to simultaneously achieve both an increased heart-cut fraction yield (as the product of the hydrocracking) and a reduced normal paraffin content in the heart-cut fraction when the untreated wax is hydrocracked by a bottom recycling system. | 06-25-2009 |
| 20090166265 | HYDROREFINING METHOD - The hydrorefining method of the invention is characterized by contacting, in the presence of hydrogen, a fuel stock comprising normal paraffins and oxygen-containing compounds, with a hydrorefining catalyst comprising a support containing USY zeolite and at least one solid acid selected from among silica-alumina, alumina-boria, silica-zirconia, silica-magnesia and silica-titania, and at least one metal selected from among metals of Group VIb and metals of Group VIII of the Periodic Table supported on the support. | 07-02-2009 |
