  • Patent number: 10859708
    Abstract: A test signal generator generates a first test signal. A test signal transmitter transmits the first test signal. An RF receiver unit receives the first test signal and a first satellite signal through a receiving antenna, and generates a second test signal and a second satellite signal, respectively. Each of first and second demodulators calculates a correlation value between the second satellite signal and the spreading code to acquire a satellite. A first failure detector unit compares a signal intensity of the second test signal with a threshold to generate a first failure detection signal. A second failure detector compares the satellites acquired by the first and second demodulator to generate a second failure detection signal. A state determiner determines whether and where a failure exists, using the first and second failure detection signals.

  • Patent number: 8008040
    Abstract: An object of the present invention is to provide a process according to which 5-ene-3-one or 3,6-dione derivatives of sterols can be synthesized with a better yield, as well as a process for production of lipid metabolism improvers, foods, drinks, and animal feeds containing the 5-ene-3-one or 3,6-dione derivatives of sterols. The process for production of 5-ene-3-one or 3,6-dione derivatives of sterols of the present invention involves preparing a culturing solution containing an Arthrobacter bacterium, which is a microorganism exhibiting a cholesterol oxidase activity, and then, adding to the culturing solution an equivalent amount of hexane so as to prepare a bilayer solution consisting of an aqueous layer and a hydrocarbon-based solvent layer. Thereafter, sterol, or a derivative thereof, is made as a substrate contained therein, a reaction performed with cholesterol oxidase at 30° C. for 2 days, and, ethanol then added to separate a hydrocarbon-based solvent layer.
