  • Patent number: 9935523
    Abstract: To maximize a power consumption reduction effect in a case of using a high-efficiency induction motor, when a conventional induction motor is changed to a high-efficiency induction motor, a mechanical device including an induction motor and a speed reduction mechanism related to the present invention increases the reduction ratio of the speed reducer such that the rotation speed of the mechanical device is equal to that in a case of using a conventional induction motor and thus the output of the mechanical device is made equal to that in a case of using a conventional inductor motor; therefore, the load conditions of the mechanical device such as a pump and a fan can be made equal to those in a case of using a conventional induction motor. Accordingly, the power consumption reduction effect by improving the efficiency of the induction motor can be maximized.

  • Patent number: 9897580
    Abstract: In a two-dimensional LC system configured to introduce components trapped in a trap column during a fractionation period T into a second-dimension column, separate components, and then detect the components using a mass spectrometer, a data collection unit receives a signal which indicates timing to delimit the fractionation period T, determines the first data item in the fractionation period T, adds measurement start point identification information to the first data item, and stores all the data in a data storage unit. A two-dimensional chromatogram creation unit recognizes the first data item in each fractionation period T from the read data, and create a two-dimensional chromatogram by aligning data so that the first data items will be aligned at the top along an abscissa.

  • Patent number: 9818536
    Abstract: A multilayer ceramic capacitor that includes an internal electrode containing at least one kind of metal A selected from the group consisting of In, Ga, Zn, Bi, and Pb and dissolved in Ni to form a solid solution. The internal electrode has a ratio of A of 1.4 atomic percent or more to a total amount of A and Ni in a near-interface region located to a depth of 2 nm from a surface of the internal electrode facing a corresponding ceramic dielectric layer. A relation between a value X of atomic percent representing the ratio of A in the near-interface region and a value Y of atomic percent representing the ratio of A in a central region in a thickness direction of the internal electrode is X?Y?1.0. Such a multilayer capacitor is formed by annealing a ceramic stack under a predetermined condition to increase the ratio of metal A in the near-interface region of the internal electrode.

  • Publication number: 20170271135
    Abstract: For a sample whose components are separated from each other, an MS2 analysis is repeatedly performed by an MS/MS unit to obtain MS2 spectra. Peak information is collected from the MS2 spectrum acquired for each micro area on a two-dimensional chromatogram. A principal component analysis processor performs a principal component analysis on the collected peak information to determine a principal component score reflecting an overall tendency of the peak pattern of the MS2 spectra. A factor loading calculator computes a factor loading for each m/z from the principal component score. A correlation information calculator computes the coefficient of correlation between each MS2 spectrum and the factor loadings. Since the MS2 spectra reflect the chemical structure of a contained component, a two-dimensional image created based on the coefficient of correlation shows the distribution of a component having a similar chemical structure to a component which is characteristically contained in the sample.

  • Patent number: 9741548
    Abstract: The mass spectrometer (1) provides an ionization chamber (11) therein with: a probe (15) having a sample to be measured flow path (155) for spraying a sample to be measured; and a standard sample flow path (255) for spraying a standard sample used for the calibration of the mass-to-charge ratio of the mass spectrum into the ionization chamber. The standard sample is intermittently introduced into the ionization chamber via a pulse valve (216). Thus, mixing of the sample to be measured and the standard sample can be prevented, while the timing according to which the standard sample is introduced can be appropriately controlled. It also becomes possible to acquire an accurate mass spectrum for each sample to be measured even in the case where a number of types of samples to be measured are introduced into the ionization chamber one after another over a short period of time.

  • Patent number: 9672330
    Abstract: A product ion spectrum is created on the basis of MS2 analysis data respectively obtained for a parent compound and a metabolite (S1 and S2). Additionally, a neutral loss spectrum, in which the mass of each product ion is replaced with a mass difference between the mass of the product ion and that of a precursor ion, is created (S3). Then, a common peak having the same mass on the neutral loss spectrums of both the parent compound and the metabolite is extracted (S4), and a complementary peak appearing on the product ion spectrum of the metabolite is extracted (S5); this peak appears at a position corresponding to the difference between the mass of the common peak and that of the precursor ion. The ion corresponding to the complementary peak is designated as a precursor ion for the next MS3 analysis (S6), and this MS3 analysis is performed (S7).
