    摘要： The invention intends to provide a dielectric porcelain composition for use in electronic devices, which has the dielectric characteristics such that the Qf value is high, the temperature coefficient τf of a resonant frequency is small and a value thereof can be controlled in a wide range in positive and negative directions in the vicinity where the relative dielectric constant ∈r is 39. According to the invention, when, in La—Pr—Al—Ga—Sr—Ti-based oxide dielectric porcelain, contents of the respective elements are limited to be within particular ranges and Sr is partially substituted by Ca, a structure having a (1-x)(La1-yLny)(Al1-zGaz)O3-x(Sr1-mCam)TiO3 solid solution as a main phase, in which a solid solution of Al—Ga—Sr-based oxide and/or a solid solution of Al—Ga-based oxide and a Sr oxide is/are precipitated in a grain boundary thereof, can be obtained, whereby the above-mentioned object can be achieved.

    摘要： An infrared radiation gas analyzer for determining the concentration of an ingredient in a sample gas has a sample gas container for containing a sample gas at a temperature at which the ingredient the concentration of which is to be determined will emit infrared radiation in a range characteristic of the ingredient and a window for allowing the infrared radiation to escape from the container. An optical chopper is positioned outside the container for interrupting the radiation escaping from the container. A filter is positioned in the path of the radiation escaping from the container and transmits only radiation in the range. An infrared radiation detector is positioned for receiving the radiation passed by the filter and emitting a signal representative of the radiation received by the detector and which is representative of the concentration of the ingredient the concentration of which is to be determined in the sample gas.
