摘要： A radio transceiver having improved impedance matching characteristics between a rod-like antenna and transmitting and receiving portions. An impedance matching circuit is provided between the antenna and a duplexer to impedance-match therebetween at a frequency within a desired signal frequency band. A transmitting signal and a receiving signal may have substantially different frequencies in which case the impedance matching circuit operates advantageously in a range between these signals, respectively. The impedance matching circuit includes a first inductor inserted between the antenna and the duplexer, a first capacitor inserted between the antenna and ground potential, and a parallel resonance circuit composed of a parallel circuit of a second capacitor and a second inductor inserted between the duplexer and ground potential.

摘要： A ceramics shaped article having a large wall-thickness and having a complicated shape, which can not be monolithically produced by a conventional molding, can be easily produced through a monolithical molding by the use of a ceramic batch containing water as a plasticizing medium and a small amount of an organic binder as a plasticizer. The ceramic shaped article can be fired into a ceramic sintered article in high dimensional accuracy and yield.
