Abstract: A cognitive function evaluation device includes: an obtainment unit that obtains utterance data indicating a voice of an evaluatee uttering a sentence as instructed; a calculation unit that calculates, from the utterance data obtained by the obtainment unit, a feature based on the utterance data; an evaluation unit that compares the feature calculated by the calculation unit to reference data indicating a relationship between voice data indicating a voice of a person and a cognitive function of the person to evaluate the cognitive function of the evaluatee; and an output unit that outputs the sentence to be uttered by the evaluatee and outputs a result of evaluation by the evaluation unit.

Abstract: In a monolithic LC filter, bent portions of external electrodes are formed by applying and firing a conductive paste in the areas of first to eighth bent segments that are formed by pattern printing, photolithography, or a thin-film forming method. The third, fourth, seventh, and eighth bent segments, which are used to form ground external electrodes, cover openings disposed between extensions of shield electrodes in the composite of the monolithic LC filter.

Abstract: An LC-included electronic component has a greatly reduced size, a greatly increased resonator Q, and outstanding reliability. Inductor via holes are successively connected in a direction in which insulating sheets are stacked to define columnar inductors. The inductor via holes each have a Y-direction dimension greater than an X-direction dimension on the X-Y plane of a section shape, and the shape has Y-direction ends of increased width. Specifically, each Y-direction end of the inductor via holes is substantially circular, and the other portions are linear.

Abstract: A monolithic conduct includes a laminated stack of insulator sheets and inductor via-holes that are connected to each other in the direction in which the insulator sheets are laminated, thereby forming columnar inductors. Coupling adjusting via-holes are also connected to each other in the direction in which the insulator sheets are laminated, thereby forming a columnar coupling adjusting conductor. The columnar coupling adjusting conductor is disposed between and substantially parallel to the columnar inductors.

Abstract: An LC resonator includes insulation sheets and inductor patterns that are electrically connected through long via-holes provided in insulation sheets, so that tubular structures each having an insulator material disposed therein and having a substantially rectangular cross section are produced. The tubular structures are laminated through sheets to define an inductor having a double structure. A capacitor pattern is opposed to the open ends of the inductor patterns, respectively, to produce a capacitor. That is, the capacitor pattern is arranged between the tubular structures. The capacitor and the inductor having the double structure define an LC parallel resonance circuit.

Abstract: A monolithic LC resonator includes insulation sheets and inductor patterns that are electrically connected through long via-holes formed in the insulation sheets. The long via-holes are arranged along the right edge and left edge of the inductor patterns, respectively. The inductor patterns and the long via-holes define an inductor having a tubular structure with a substantially rectangular cross-section and filled with an insulator therein. A capacitor pattern is opposed to the open ends of the inductor patterns through the sheets, respectively, to define a capacitor. That is, the capacitor pattern is laminated inside of the tubular structure of the inductor. The capacitor and the inductor having the tubular structure define an LC parallel resonance circuit.

The first and second three-stage band-pass filters are coupled through impedance matching patterns. An inductor of each of the resonators is defined by via-holes formed on insulator sheets which are connected in sequence in the laminating direction of the sheets.

Abstract: A band pass filter includes LC resonators defined by laminated layers and is constructed such that the resonant frequencies of the LC resonators shift in the same direction when laminated layers deviate from each other. In the arrangement of the band pass filter, the inductor pattern of a first LC resonator and the capacitor pattern of a second LC resonator are disposed on a surface of a first ceramic sheet. The inductor pattern and the capacitor pattern extend to the same side of the first ceramic sheet. In addition, the capacitor pattern of the first LC resonator and the inductor pattern of the second LC resonator are disposed on a surface of a second ceramic sheet. The capacitor pattern and the inductor pattern extend to the same surface of the second sheet.

Abstract: A compact multi-layer composite electronic component is such that electric couplings occurring between a plurality of high-frequency circuits are reduced. In this compact multi-layer composite electronic component, the axes of the inductors of LC resonators defining a first band pass filter circuit (BPF 1) are disposed substantially perpendicularly to the axes of the inductors of LC resonators defining a second band pass filter circuit (BPF 2). The inductors of the LC resonators defining the BPF 1 are constituted by joining via-holes disposed on insulating sheets. The inductors of the LC resonators defining the BPF 2 are constituted of inductor patterns provided on the surfaces of specific ones of the insulating sheets.
