摘要： Proposed are a resonator which can easily establish coupling with input/output means, an external circuit, etc., and a filter, duplexer and communication apparatus each having a wide-band frequency characteristic. Electrodes having polygonal openings defined therein are formed in both principal planes of a dielectric substrate such that the openings are positioned to face each other. The dielectric substrate is arranged with the aid of spacers between a metal-made upper conductor case and a lower conductor case having a shield conductor formed therein, the upper and lower conductor cases being positioned to face each other with gaps left relative to the dielectric substrate. Portions of the dielectric substrate between pairs of the openings facing to each other serve as resonance areas and are coupled respectively with input/output electrodes.

摘要： The invention provides a dielectric resonator for example in the TE010 mode characterized in that electrodes are formed on both principal surfaces of a dielectric plate in such a manner that influence of spurious waves propagating in a space between the electrodes and a conductive plate is prevented thus preventing the reduction in Qo and degradation in the attenuation characteristic in the frequency ranges outside the passband. The inner diameter of the cavity is selected such that when the cavity is regarded as a waveguide the cutoff frequency of the waveguide becomes higher than the resonant frequency of a resonance region and such that the inner diameter of the cavity is greater than a non-electrode part.

Electrodes are formed on both principal planes of a dielectric plate (3) with pairs of electrode non-formed portions (4a, 4b, 4c, etc.) defined in the electrodes in opposing relation so that areas positioned between the electrode non-formed portions serve as resonance areas. Microstrip lines (9, 10) are provided on an upper surface of a base plate (6), and an electrode (11) is formed in spaced relation from the microstrip lines (9, 10) by a predetermined distance. Through holes (13) for making electrical conduction between the electrodes formed on both principal planes of the base plate (6) are bored in the base plate in array.

摘要： Proposed is a novel synthetic route for the preparation of 1,4-anhydro-2-deoxy-D-erythropentitol, which is a useful material in the synthesis of antibiotics, starting from 2-deoxy-D-ribose via 2-deoxy-D-erythropentitol as an intermediate. 2-Deoxy-D-erythropentitol can be prepared by the hydrogenation of 2-deoxy-D-ribose with Raney nickel as the hydrogenating catalyst in a high efficiency and at low costs as compared with the prior art methods using, for example, sodium borohydride as the hydrogenating agent. 2-Deoxy-D-erythropentitol is subjected to a dehydration cyclization reaction to be converted into 1,4-anhydro-2-deoxy-D-erythropenti-tol under a substantially anhydrous condition which is accomplished by heating a reaction mixture containing 2-deoxy-D-erythropentitol suspended in an organic solvent capable of forming an azeotropic mixture with water such as toluene under reflux so as to azeotropically remove the water condensate.
