Abstract: Three-axis acceleration component data from an acceleration sensor is split into three stationary components and three movement components. The axial direction of movement is detected based on the movement component having the maximum value. A shake duration is detected based on a time period from when this maximum movement component exceeded a an upper limit value of a specific range until it once again reaches a value in the specific range after falling below a lower limit value, or on a time period from when the movement component fell below the lower threshold value until it once again reaches the specific range after exceeding the upper threshold value. The magnitude of movement is determined by comparing the shake duration to a certain period, or by comparing the vector integral value over the shake duration to a certain threshold value.

Abstract: In exemplary embodiments, first and second parameters are obtained for each of different temperatures of the magnetic recording layer. The absolute value of the first parameter for each magnetic grain has a minimum value when the temperature of each magnetic grain reaches a predetermined temperature that increases as the Curie temperature increases, and decreases as the Curie temperature decreases. The second parameter is related to the standard deviation of the coercivity distribution of the magnetic grains divided by the coercivity of the magnetic recording layer. The method calculates a value where the absolute measurement value of the first parameter has a minimum value and the temperature of the magnetic recording layer at which the standard deviation of the coercivity distribution of the magnetic grains divided by the coercivity of the magnetic recording layer has a maximum value.

Abstract: The present invention aims at providing a method and apparatus for analyzing a mass spectrum on which multivalent ion peaks originating from a target compound appear, and calculating the mass of the target compound. First, each peak on the mass spectrum is analyzed to detect isotopic clusters, and the valence and the representative point (m/z value) of each isotopic cluster are obtained (S1 through S3). Since the range of the m/z value of the component which is added to or desorbed from the compound is limited, by using this factor, the isotopic clusters originating from the same compound are deduced. By combining the deduced isotopic clusters, the candidates for the m/z value of the added/desorbed component are deduced (S5).
