摘要： An object of the invention is to provide a dielectric porcelain composition with low rate of phase change of a cordierite phase as a primary crystal phase, in which as a result of the low rate of phase change the dielectric constant is from 4.5 to 6 and Q value is 1,000 or more at 60 GHz, and to provide a dielectric resonator and nonradiative dielectric strip using the same. The dielectric porcelain composition comprises, as a principal component, a complex oxide having a molar composition xMgO·yAl2O3·zSiO2 (wherein 10≦x≦40, 10≦y≦40, 20≦z≦80, and x+y+z=100), and a ratio of a (241) peak intensity βp(241) and a (222) peak intensity βp(222) of X-ray diffraction of a β phase of a 2MgO·2Al2O3·5SiO2 phase, which is a primary crystalline phase of the complex oxide, is 0.8≦βp(241)/βp(222)≦1.3.

摘要： A module equipped with a non-radiative dielectric waveguide in accordance with this invention comprises a pair of parallel flat conductors arranged at a space of 1/2 or below of a high frequency signal wavelength .lambda. and a dielectric strip extending between these parallel flat conductors. This dielectric strip is formed from a cordierite ceramic having a dielectric constant of 4.5 to 8, especially 4.5 to 6. Conversion of an electromagnetic wave of LSM mode to an electromagnetic wave of LSE is minimal. When the module has a dielectric strip having a steep curved portion having a small radius of curvature, the transmission is possible with a low loss, and the band width of a high frequency signal is broad.

摘要： For use together with a device for detecting a plurality of information positions where postal information pieces are described, an arrangement is for detecting one of the information positions that is described on an opaque label attached to a transparent envelope. Responsive to a regularly reflected beam from the opaque label, a label positon detector detects a label position where the opaque label is attached to the transparent envelope to produce a label position signal representative of the label position. Responsive to the label position signal, a selector selects the above-mentioned one of the information position.
