摘要： A hemispherical dielectric resonator is arranged on a conductive substrate with a flat surface of the resonator in contact with the conductive substrate and fixed by a pair of fixing blocks. The dielectric resonator is fed with a signal feeder at a position at one side of the resonator such that intensity of the electric field is higher at that position. The fixing blocks contact a portion of the dielectric resonator where the intensity of the electric field is of a local minimum.

摘要： A strip dual mode loop resonator includes loop-shaped strip line having a pair of straight strip lines arranged in parallel, an electric length of the loop-shaped strip line being equivalent to a wavelength of a microwave circulated in the loop-shaped strip line in two different directions according to a characteristic impedance of the loop-shaped strip line, and the straight strip lines being coupled to each other in electromagnetic coupling to change the characteristic impedance of the loop-shaped strip line. The microwave is transferred from an input strip line to the loop-shaped strip line through electromagnetic field induced by the microwave. Thereafter, the microwave is reflected in the straight strip lines of the loop-shaped strip line to produce reflected microwaves circulated in opposite directions. Thereafter, the reflected waves are resonated and filtered in dual mode in the loop-shaped strip line. Thereafter, the microwave formed of the reflected waves is transferred from the loop-shaped strip line to an output strip line through electromagnetic field induced by the microwave.

摘要： A transmitter apparatus wherein a simple structure is used to successfully suppress the degradation of error rate performance that otherwise would be caused by fading or the like. There are included encoding parts (11—1-11—4) that encode transport data; a mapping part (3304) that performs such a mapping that encoded data sequentially formed by the encoding parts (11—1-11—4) are not successively included in the same symbol, thereby forming data symbols; and a symbol interleaver (3301) that interleaves the data symbols. In this way, a low computational complexity can be used to perform an interleaving process equivalent to a bit interleaving process to effectively improve the reception quality at a receiving end.

摘要： Provided is a radio communication method capable of optimally using the wide-band communication enabled time while maintaining power saving in an ad hoc network. According to this method, in the ad hoc network using the wide-band communication and a narrow-band communication, transmission and output of the narrow-band synchronization tone signal and the resynchronization tone signal are controlled so that the reach radius of the narrow-band synchronization signal and the resynchronization tone signal exceeds the reach radius of the wide-band signal (milli-wave UWB signal). Thus, when radio communication devices pass by each other, super frame synchronization is completed before reaching the wide-band communication enabled range of the ad hoc network, thereby optimally using the wide-band communication-enabled time.

摘要： An electronic endoscope has an insert section to be introduced into a human body cavity. A distal portion of the insert section contains a CCD and a printed circuit board to which the CCD is bonded. In the insert section, a cable bundle being a bundle of coaxial cables extends. Each coaxial cable consists of a signal line, insulation surrounding the signal line, a braided wire surrounding the insulation, and an insulating jacket. The cylindrical braided wire is stranded into a single line, and is soldered as a ground line to a ground terminal of the printed circuit board. The signal line is pulled out of the coaxial cable with a length longer than the ground line. The signal line is soldered to an input/output terminal of the printed circuit board with a larger sag than the ground line.

摘要： A UWB transmission apparatus that, in a system using a mixture of amplitude and phase modulation schemes, can support both of the amplitude and phase modulation schemes, while preventing the signal powers of amplitude-modulated signals from degrading. In this UWB transmission apparatus, if the modulation mode is of QPSK, a mapping part (121) selects one of four signal points on the IQ plane in accordance with a 2-bit data, and outputs information related to the I- and Q-components of the selected signal point to a QPSK/ASK modulated signal forming part (122). If the modulation mode is of ASK, the mapping part (121) selects the origin point on the IQ plane when the data being ‘0’ and selects one of four signal points on the IQ plane, similarly to the case of QPSK modulation, when the data being ‘1,’ and outputs information, which is related to the selected signal point, to the QPSK/ASK modulated signal forming part (122).
