Dielectric resonator antenna for a mobile communication

Abstract: A hemispherical dielectric resonator is arranged on a metal substrate to make a flat surface of the hemispherical dielectric resonator contact with the metal substrate, and a dielectric wave-guiding channel is connected with a curved side surface of the hemispherical dielectric resonator. Therefore, a dielectric resonance antenna in which the hemispherical dielectric resonator and the dielectric wave-guiding channel are placed on the same metal substrate is obtained. A signal transmitting through the dielectric wave-guiding channel is fed in the hemispherical dielectric resonator, the hemispherical dielectric resonator is resonated, and an electromagnetic wave is radiated. Therefore, the dielectric resonance antenna functions as a wave radiation device.

Battery and maintenance service system for power supply device

Abstract: A portable personal computer (2) accesses a service handling server (1) established on the Internet (5) to transmit data from a power supply monitor unit (4). The service handling server (1) checks, by referring to a power supply information database (22), for abnormality data received with a type of a portable personal computer (2) specified, and, when it is not abnormal, sends back an OK answer, but e-mails abnormality handling information when it is abnormal.

Structural basis for the fast phase change of Ge2Sb2Te5: Ring statistics analogy between the crystal and amorphous states

Abstract: The three-dimensional atomic configuration of amorphous Ge2Sb2Te5 and GeTe were derived by reverse Monte Carlo simulation with synchrotron-radiation x-ray diffraction data. The authors found that amorphous Ge2Sb2Te5 can be regarded as “even-numbered ring structure,” because the ring statistics is dominated by four- and six-fold rings analogous to the crystal phase. On the other hand, the formation of Ge–Ge homopolar bonds in amorphous GeTe constructs both odd- and even-numbered rings. They believe that the unusual ring statistics of amorphous Ge2Sb2Te5 is the key for the fast crystallization speed of the material.

Power transmitting apparatus, power receiving apparatus, and power transmitting method

Abstract: Provided is a electric power transmitting apparatus ( 300 ) that has sub-electric power transmission mode, and main electric power transmission mode for transmitting power larger than that transmitted in the sub-electric power transmission mode. A power transmitting unit ( 310 ) transmits power in a wireless manner. A electric power transmission control unit ( 320 ) controls, in sub-electric power transmission mode, power to be transmitted by means of the power transmitting unit ( 310 ) and transmission timing of the electric power transmission such that at least power that the electric power receiving apparatus needs to transmit power request notification is transmitted at random intervals. A electric power transmission control unit ( 320 ) performs switching to the main electric power transmission mode, in the cases where a communication unit ( 350 ) acquired the power request notification transmitted from the electric power receiving apparatus.

Bar-code reader permitting selective use of a whole or a part of an image sensor

Abstract: A bar-code reader includes a selection circuit which selects one of two operating modes of reading a bar code label by using the whole section or partial section of an image sensor.
