Abstract: A multiple regression analysis apparatus capable of accurately performing a multiple regression analysis is provided. A multiple regression analysis apparatus includes a determination unit, a division unit, an analysis unit, and a regression equation acquisition unit. The determination unit determines one of a plurality of explanatory variables that is effective as a parameter when stratification of a plurality of data sets is performed to be a stratification explanatory variable. The division unit divides the plurality of data sets for each layer using the stratification explanatory variable. The analysis unit performs a multiple regression analysis on each of groups of the plurality of data sets that have been divided. The regression equation acquisition unit acquires an integrated multiple regression equation in which results of the multiple regression analysis are integrated.

Abstract: A vehicle bottom surface imaging system is equipped with a housing above which a vehicle can pass, first and second reflecting mirrors provided inside the housing and sequentially arranged along a passing direction of the vehicle, and first and second cameras provided inside the housing and arranged apart from each other in a vehicle width direction. The first reflecting mirror reflects the light incident from above the housing onto the first camera. The second reflecting mirror reflects the light incident from above the housing onto the second camera. The first reflecting mirror is so provided as to be changed over between a service state where the light incident from above the housing is reflected onto the first camera and a folded state where the reflected light from the second reflecting mirror onto the second camera is not blocked.

Abstract: One aspect of the present disclosure relates to a method for analyzing mass spectrometry data of an analysis target substance comprising: acquiring mass-to-charge ratios and relative intensities of one or more detected ion peaks; preparing mass data of the analysis target substance consisting of the relative intensities, the mass-to-charge ratios, and differences in the mass-to-charge ratios of the one or more ion peaks; and determining an identification candidate for the analysis target substance or partial structure thereof. Another aspect of the present disclosure relates to a computer program medium storing a computer program for executing the method for analyzing mass spectrometry data of an analysis target substance, and a device for analyzing mass spectrometry data of an analysis target substance.

Abstract: The present invention provides a non-aqueous electrode secondary battery supplied with a non-aqueous electrolyte comprising an overcharge additive. The positive electrode material layer constituting the positive electrode in the non-aqueous electrolyte secondary battery is characterized by having a differential pore volume peak A as well as a peak B located on the smaller pore diameter side than the peak A in a pore diameter range of 0.05 ?m to 2 ?m in a pore size distribution curve measured by a mercury porosimeter, wherein the pore size distribution curve has a minimum C corresponding to a minimum differential pore volume between the peak A and the peak B, such that a ratio (XC/XL) of the minimum C's differential pore volume XC to a differential pore volume XL, which is the larger between the peak A's differential pore volume XA and the peak B's differential pore volume XB is 0.6 or larger.

Abstract: A method of manufacturing a negative electrode plate for a non-aqueous secondary battery is disclosed, in which it is possible to assess whether or not a binder is localized in an electrode surface without lowering the productivity of the negative electrode plate. The method includes coating an electrode mixture containing at least a negative electrode active material and a binder to a current collector and drying the coated electrode mixture. The method includes an inspection step of measuring a reflectance of a coating surface of the negative electrode plate to thereby determine the quality of the negative electrode plate. If the reflectance of the coating surface of the negative electrode plate falls within a range of 15 to 35% when an incident angle and a light receiving angle each fall within the range of 80° to 90°, the negative electrode plate is determined to be excellent.
