摘要： There is provide a mobile radio apparatus capable of suppressing a mismatching loss, and increasing a transmission/reception sensitivity by means of instantly and adaptively matching the impedance between the antenna and the transmission/reception circuit whatever situation a mobile radio apparatus, such as a mobile phone or the like, may be. In a mobile radio apparatus (1), when starting control of the matching circuit (102), a control section (105) evaluates an initial chromosome stored in a storage section (106), and if there is an initial chromosome for providing an impedance matching, controls the matching circuit (102) so as to have a load value corresponding to this initial chromosome. If there is no initial chromosome for providing the impedance matching, the control section (105) evolves the initial chromosome with a genetic algorithm, derives a chromosome for providing the impedance matching, and controls the matching circuit (102) so as to have a load value corresponding to the derived chromosome.

摘要： In an apparatus for measuring a specific absorption rate (SAR), a first near magnetic field distribution of a radio wave radiated from an array antenna of a reference antenna including a plurality of minute antennas is measured, and an SAR distribution with respect to the radio wave radiated from the array antenna is measured with a predetermined phantom. Then a distribution of a transformation coefficient α is calculated by dividing the measured SAR distribution by a square of the measured first near magnetic field distribution, a second near magnetic field distribution of a radio wave radiated from a measured radio communication apparatus is measured, and an SAR distribution with respect to the radio wave radiated from the radio communication apparatus is calculated by multiplying a square of the measured second near magnetic field distribution by the calculated distribution of the transformation coefficient α.

This apparatus connects variable capacitance capacitors VC1 and VC2 for impedance adjustment to transmission antenna element TA1, connects variable capacitance capacitors VC3 and VC4 to reception antenna element RA1 respectively, provides beforehand capacitance values of respective variable capacitance capacitors which are impedance matched in a table in a one-to-one correspondence with the distances between the antenna elements and human body and stores the table in storage section (106). The apparatus completes adaptive control processing for any one of transmission antenna element TA1 and reception antenna element RA1, reads other capacitance values corresponding to the capacitance value at that moment from the table and performs adaptive control processing on other antenna elements using the read values as initial values.

摘要： The invention aims to reduce the size of a disk clamp mechanism to be built into a disk player. The clamp mechanism comprises: a disk clamp portion formed integrally with a turntable; a clamper; and a damper holder for holding the damper via a damper mounting shaft adapted to hold the damper in rotatable fashion, wherein a flange portion provided at an end of the damper mounting shaft is placed within a space formed inside the clamper. The damper comprises a peripheral portion and a chamber portion in which the space is formed, and the disk clamp portion has a recessed groove portion engageable with the chamber portion, the structure being such that, when the disk is clamped, the end portion of the chamber portion is accommodated into the disk clamp portion, thus achieving a size reduction by reducing the height in a direction perpendicular to the disk.

The N antennas are provided respectively at vertexes of a polygon of the same number as the number N of the antennas, so that each pair of antennas of the plurality of pairs of antennas opposes to each other. An adaptive control circuit takes an adaptive control over radio signals using one pair of antennas opposing to each other among the N antennas. In the adaptive antenna apparatus, the each pair of antennas is provided to oppose to each other so that axes of directions of main beams of the directional characteristics of the each pair of antennas substantially coincide with each other.

摘要： A top conductor 11, a ground conductor 12, and side conductors 13 form an antenna box having two openings 22 and 23. Antenna elements 14 and 15 are placed inside of the antenna box, and are connected to power supply points 16 and 17, respectively. A power supply control circuit 20 has a switching function of connecting either one of the power supply points 16 and 17, to an external connecting terminal 21. Depending on the antenna element 14 or 15 being operated, the antenna has a directivity biased to a desired direction. The power supply control circuit 20 may have a signal combining/separating function, a phase shifter 26, or an amplitude adjusting circuit 27. With this, it is possible to provide a small, slim antenna capable of biasing the directivity to a desired direction and controlling the directivity even after installation.

摘要： A transmitting unit of a portable telephone apparatus transmits radio signals by using at least two antennas and simultaneously energizing those antennas with a predetermined amplitude ratio and a predetermined phase difference so that the direction of the main beam of a radiation pattern has a direction substantially opposite to that of the audio radiating direction from a speaker, and so that the mean effective gain is larger than that of when a single antenna is energized. The above energization of at least two antennas is formed only for transmission of telephone speech. A receiving unit of the portable telephone apparatus receives radio signals by using at least two antennas, and selectively receives, by the diversity receiving system, the radio signal having the highest level of those radio signals received by those antennas.
