    摘要: A multilayer ceramic electronic component comprising an element body in which a dielectric layer and an internal electrode layer are stacked. The dielectric layer is constituted from a dielectric ceramic composition including; a compound having a perovskite structure expressed by a formula of ABO3 (A is at least one selected from Ba, Ca, and Sr; B is at least one selected from Ti, Zr, and Hf); an oxide of Mg; an oxide of rare earth elements including Sc and Y; and an oxide including Si. The dielectric ceramic composition comprises a plurality of dielectric particles and a grain boundary present in between the dielectric particles. In the grain boundary, when content ratios of Mg and Si are set to D(Mg) and D(Si) respectively, D(Mg) is 0.2 to 1.8 wt % in terms of MgO, and D(Si) is 0.4 to 8.0 wt % in terms of SiO2.

    摘要: A light-emission measuring apparatus which is capable of eliminating various secondary problems in addition to shutting off strong light from the external and preventing crosstalk. The light-emission measuring apparatus is equipped with a box-type carrier 9 having an open top surface and made to accommodate a microplate 7 comprising a plurality of wells. The box-type carrier is disposed to be movable horizontally. A light-obstruction plate having a light-receiving hole 11 is disposed above the box-type carrier to be movable vertically. The light-obstruction plate 5 is brought into tight contact with a circumference of the box-type carrier 9 to establish a black box when being moved downwardly. Further, the light-receiving hole 11 of the light-obstruction plate 5 has a cylindrical projecting bottom surface 12 so that its bottom surface side outer circumference comes into tight contact with a circumference 13 of an opening of a well top surface of the microplate 7.

    摘要: A flame ionization detector is used for carrying out a quantitative analysis of chromatographically-separated substances in thin-layer chromatography. The detector comprises a gas burner for forming a hydrogen flame. A thin-layer chromatographic element or a rod-like element which carries the chromatographically-separated substances is passed through the hydrogen flame so that the separated substances are burned and ionized. The detector further comprises an electrode which is disposed above the hydrogen flame and exposed to the ionized gas generated by the burning of the separated substances. A voltage is applied between the gas burner and the electrode so that the former is given a positive polarity and the latter a negative polarity. An electric current which is caused by the exposure of the negative electrode to the ionized gas is detected and amplified. A third electrode is disposed to surround the negative electrode so that an amount of each of the separated substances can be proportioned to the amplified output value thereof.
