Abstract: A magnetic field generator includes: an upper layer coil composed of a first conductive material and forming a loop circuit having a coil portion; a lower layer coil composed of a second conductive material and forming a loop circuit having a coil portion arranged opposite to the coil portion of the upper layer coil at a predetermined distance; and a substrate supporting the upper layer coil and the lower layer coil and having a dielectric material between the upper layer coil and the lower layer coil. High-frequency currents of opposite phases are passed through the upper layer coil and the lower layer coil, respectively, and a length per loop of the coil portion in the upper layer coil and the coil portion in the lower layer coil is matched to one wavelength of the high-frequency current.

Abstract: A biological sound detection device includes a housing, a medium, a transducer unit, a detection unit, and a pressure adjusting unit. The medium has an acoustic impedance closer to water than air. The transducer unit is arranged in the housing, and converts a biological sound transmitted through the medium into an electric signal. The detection unit provides, together with the housing, an accommodation region that accommodates the medium, detects the biological sound, transmits the biological sound to the medium, and is deformable in a direction approaching the transducer unit according to a load of a physical body. The pressure adjusting unit adjusts a pressure of the medium so as to suppress an increase in the pressure of the medium due to deformation of the detection unit.

Abstract: A magnetic field generator includes: an upper layer resonance coil composed of a first conductive material and forming a loop circuit having a coil portion; a lower layer coil composed of a second conductive material and forming a loop circuit having a coil portion arranged opposite to the coil portion of the upper layer coil at a predetermined distance; and a substrate supporting the upper layer coil and the lower layer coil and having a dielectric material between the upper layer coil and the lower layer coil. A high-frequency current is supplied to the lower layer coil and a high-frequency current having a phase opposite to that of the high frequency current supplied to the lower layer coil flows through the upper layer coil. A length per loop of the coil portion in the upper layer coil and the coil portion in the lower layer coil is matched to one wavelength of the high-frequency current.

Abstract: A radar device including a transmission antenna; a reception antenna; and a controller detecting target information about a target by transmitting a transmission wave from the transmission antenna in multiple transmission/reception modes and by receiving a reception wave by the reception antenna. The multiple transmission/reception modes include: a scanning mode performing beam scanning within a detection angle range; a provisional tracking mode irradiating the transmission wave from the transmission antenna to each of the targets detected in the scanning mode for provisionally detecting target information; and a main tracking mode decisively detecting the target information of each of the targets by irradiating the transmission wave to the target using a transmission wave irradiation time that is set based on the target information provisionally detected in the provisional tracking mode.
