Abstract: <P>PROBLEM TO BE SOLVED: To provide a technique of information processing for objectively determining the main cause of stock price fluctuaion, and reporting it to a customer.  <P>SOLUTION: It is determined that the main cause of fluctuation is related to a whole market when a stock price is moved up or down (fluctuation) by the same percentage, e.g., not less than 5%, in the same direction as in an A company, concerning 80% or more descriptions, for example. It is determined that the main cause of the fluctuation is related to the whole "industry" when there are not less than 80% companies belonging to the industry to which the A company belongs, where not less than 5% is moved in each description. When the rate of the companies with stock prices moved by not less than 5% in the same direction as the object description among the respective descriptions belonging to a theme to which the object description belongs is not less than a prescribed value, the main cause of a stock price gyration is determined to be related to the theme.

Abstract: <P>PROBLEM TO BE SOLVED: To provide a heating device which can quickly detect abnormally high temperature and prevent overheating effectively, even when the temperature of a object to be heated rises quickly due to electromagnetic induction heating, and to provide a fixing device which uses such a heating device.  <P>SOLUTION: An inverter circuit 28 switches a direct current with drive signals (pulse signals) from a drive circuit 41 and supply a high-frequency current to an exciting coil 22. The ON duty width is adjusted so that a prescribed electric power value, outputted from an electric power indicating device 42, is supplied to the exciting coil and a switching device 33 is ON/OFF converted 33 to make the drive signals. Thus, when a high-frequency current is being supplied, a voltage detecting device 36 detects flyback voltage generated at an LC resonance circuit, and a fault detecting device 37 compares it to a standard voltage value. The standard voltage value is outputted on the basis of the prescribed power value. Then abnormally high temperature of the exciting coil causes deterioration of the magnetic coupling of the inverter circuit, which results in the increase in the flyback voltage value and is detected as an abnormality.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
