摘要： A gas determination method uses a sensor having a field-effect transistor structure including a gate electrode, an insulating film formed on the gate electrode, a source electrode and a drain electrode formed on the insulating film, and a graphene layer formed on the insulating film and connecting the source electrode and the drain electrode to each other. The gas determination method includes: supplying gas to the graphene layer; applying a first voltage to the gate electrode for a predetermined period of time; and thereafter measuring a change in a current flowing between the source electrode and the drain electrode when a sweep voltage is applied to the gate electrode, repeating the same current measurement with a second voltage different from the first voltage, and determining the gas based on the measurement results.

摘要： A multi-layer ceramic capacitor includes a multi-layer unit and a side margin. The multi-layer unit includes a capacitance forming unit and a cover. The capacitance forming unit includes ceramic layers laminated in a first direction and internal electrodes disposed between the ceramic layers and mainly containing nickel. The cover covers the capacitance forming unit from the first direction. The side margin covers the multi-layer unit from a second direction orthogonal to the first direction. The internal electrodes each include an oxidized area adjacent to the side margin and intensively including a metal element that forms an oxide together with nickel. The capacitance forming unit includes a first portion adjacent to the cover and a second portion adjacent to the first portion in the first direction and including the oxidized area having a smaller dimension in the second direction than that of the oxidized area of the first portion.

摘要： A multilayer piezoelectric element includes a ceramic base body, a pair of external electrodes, multiple internal electrodes, and surface electrodes. The ceramic base body is formed by a piezoelectric ceramic. The pair of external electrodes cover a pair of end faces. The multiple internal electrodes are stacked inside the ceramic base body along a thickness direction crossing at right angles with a longitudinal direction, and connected alternately to the pair of external electrodes in the thickness direction. The surface electrodes are provided on a pair of principal faces, respectively, and are each connected to the external electrode different from the one to which the internal electrode adjacent in the thickness direction is connected. The pair of external electrodes have a higher porosity than the surface electrodes.

摘要： One object is to provide a method and a device for calculating core loss accurately. A calculation method includes: calculating core loss characteristics of a magnetic part having no superimposed direct current flowing therein, the magnetic part being made of one or more magnetic materials; and calculating a value of core loss of the magnetic part by multiplying the core loss characteristics by a rate of change of the core loss of the magnetic part caused by a superimposed direct current.
