摘要： A radio communication device of the present invention comprises a first antenna, a second antenna, a phase varying section which varies a phase of a first RF signal received by or transmitted from the first antenna, and a phase control means which causes the phase varying section to vary a phase amount which is a varied amount of the phase of the first RF signal received by or transmitted from the first antenna. Thus, it is possible to prevent that a size of a device configuration increases and avoid that a reception electric field level is lowered in a localized area.

摘要： Four antenna units arranged adjacent to each other are respectively connected to switches, and are connected to load impedance elements via the switches, or connected to an output terminal and a comparator via a switch. Another ends of the load impedance elements are grounded. The comparator judges which antenna unit receives a radio signal having the maximum signal level among the antenna units. A controller controls the switches and the switch so that the antenna unit that receives the radio communication signal having the maximum signal level is connected to the output terminal and the other antenna units are connected to the load impedance elements.

摘要： A dielectric antenna of the present invention includes a pillar-shaped dielectric section for radiating an electromagnetic wave being fed thereto. The dielectric section includes a depressed portion in an upper portion thereof. The vertical cross section of the depressed portion has such a shape that the height of the dielectric section gradually increases toward the side surface of the dielectric section. For example, the depressed portion is a notch having a V-shaped vertical cross section. Alternatively, the depressed portion includes a flat surface portion.

摘要： In case of performing so-called “PET acquisition”, a nuclear medical diagnosis apparatus according to the present invention does not set only gamma rays which imparted predetermined energy values (for example, energy values of and above a Compton edge), as subjects for coincidental counting acquisition (coincidence acquisition), but it discriminates also further gamma rays which caused a photoelectric effect after having undergone Compton scattering once in a radiation detection unit, so as to set them as subjects for the coincidental counting acquisition. Concretely, if the added value of energy values observed in two detection elements is “near 511 keV”, the existence of the further gamma ray is presumed, and the acquisition thereof is possible. Besides, that one of the two detection elements as to which energy near the Compton edge is observed can be specified as the incident position of the gamma ray on the radiation detection unit.
