Abstract: To provide a heating apparatus for a gas chromatograph, and a heating method for a gas chromatograph, wherein vapor phase components can be analyzed at an arbitrary temperature and can be instantaneously heated and pyrolized at a set temperature, thereby enabling analysis to be carried out with good reproducibility. The heating apparatus for a gas chromatograph 10 is structured in that the ceramic heater 33 is disposed around the periphery of the sample tube 31 to heat the sample 1 housed in the sample tube 31, the temperature of the sample 1 is incrementally elevated, and the high-frequency coil 35, disposed around the periphery of the ceramic heater 33, heats the pyrofoil 32 wrapping the sample 1 to the Curie point, and the sample 1 is instantaneously heated and pyrolized.

Abstract: A fault monitoring apparatus for a mobile communication system is capable of quickly detecting a fault and will prevent a radio wave level measurement test from being carried out unnecessarily. A call loss information collecting unit detects the numbers of outgoing and incoming calls and the numbers of base-station-disconnected calls in respective components of base stations, and accumulates and stores the detected numbers in corresponding memory areas of a call loss information table. A test region determining unit reads the accumulated numbers of outgoing and incoming calls and the accumulated numbers of base-station-disconnected calls from the call loss information table, and calculates call loss probabilities in the respective components. The test region determining unit also specifies a component of the base stations which is to be automatically tested for fault detection, based on the calculated call loss probabilities.
