  • Patent number: 10640867
    Abstract: The present disclosure provides a method for manufacturing a metallized film, the metallized film including: a dielectric film; a vapor-deposited metal electrode formed on a surface of the dielectric film. The vapor-deposited metal electrode includes a plurality of parts which have mutually different resistance values. The method includes a step of letting oil adhere to a region in the surface of the dielectric film on which the vapor-deposited metal electrode is to be formed and then bringing a vapor of metal into contact with the surface of the dielectric film. A quantity per unit area of the oil adhering to a part of the region on which a part of the vapor-deposited metal electrode having a relatively low resistance value is to be formed is smaller than a quantity per unit area of the oil adhering to another part of the region on which another part of the vapor-deposited metal electrode having a relatively high resistance value is to be formed.

  • Patent number: 9915594
    Abstract: Herewith disclosed is a sample analyzer comprising: a measurement section configured to perform a measurement on a sample and generate a measurement value according to the concentration of an analyte in the sample; a memory storing a calibration curve; an analysis section; an output section; and an instruction receiver. When the instruction receiver receives an instruction to perform a diluting measurement on a calibration sample, the measurement section dilutes the calibration sample by a predetermined ratio and performs a measurement on the diluted calibration sample, and the analysis section determines the concentration of the analyte in the diluted calibration sample by applying a measurement value obtained from the diluted calibration sample to the calibration curve. Information generated based on the determined concentration and the known concentration is output.
