Abstract: To provide a positioning system, a positioning method, and a positioning server, which are capable of improving accuracy in detection of a position. In a positioning system, three or more access points connected to a terminal station by wireless communication are connected to a positioning server through a network, the access points transmit, to the positioning server, information regarding times of having received a signal transmitted from any one of the access points or the terminal station, and the positioning server measures a position of the terminal station based on the information regarding the times, the information having been received from the access points.

Abstract: The cost of a receiving unit is reduced by simplifying its structure and the receiving unit structure further reduces the unit from being influenced by noises and the like generated by the main body of the television receiver. A digital television signal receiving unit includes of a metallic case, a frequency conversion circuit housed in the metallic case for converting a frequency of a received digital television signal into an intermediate frequency signal or a base band signal and an OFDM signal processing circuit for processing either the intermediate frequency signal or the base band signal and outputting an MPEG bit stream signal. Operations of the frequency conversion circuit and the signal processing circuit are controlled by a control signal outputted from a control circuit arranged outside the metallic case.

Abstract: The present invention relates to new nucleic acid sequences, which code for a geranylgeranyl reductase, a method for producing new plants which contain the new DNA sequence and the content of tocopherol and/or chlorophyll of which is altered in comparison to wild-type plants, these new plants, parts and products thereof and plant cells as well as the use of the DNA sequences for the manipulation of tocopherol, chlorophyll and/or vitamin K1 content in transgenic plants, parts and products thereof and plant cells.
