摘要： A superconductor layer is formed on one side of a dielectric substrate, and with this superconductor layer as a conductor layer of the bottommost layer, superconductor layers and dielectric layers are alternately laminated with each other. Thus, a superconducting multilayer electrode is provided which is laminated with at least one TEM mode transmission line which is constituted of a pair of superconductor layers with a dielectric layer sandwiched in between, and the superconductor layer and the dielectric layer have film thicknesses which are set so that the maximum value of the current density flowing through each superconductor layer becomes the same. The resistance to electric power of the superconducting multilayer electrode is proportional to the number of laminated layers.

摘要： A transmitter-receiver whose overall size can be reduced by decreasing areas occupied by a bend portion and a coupler portion of a nonradiative dielectric (NRD) waveguide. The size is not restricted by the radius of curvature and the bending angle of the bend portion. In this transmitter-receiver, the NRD waveguide is adapted so that waves are transmitted in a single mode, namely, LSM01 mode. Further, an oscillator, an isolator, a mixer and a coupler are placed in the rear of a dielectric lens. Thus, the transmitter-receiver fits within the size of the antenna.

摘要： A In a noise suppression apparatus, an extractor extracts a noise component from an audio signal. A stationary noise estimator estimates stationary noise included in the noise component. A first noise suppressor removes a spectrum of the stationary noise from a spectrum of the audio signal to an extent determined by a subtraction factor. A non-stationary noise estimator estimates a spectrum of non-stationary noise by subtracting the spectrum of the stationary noise from the spectrum of the noise component. A factor setter generates a filtering factor for emphasizing a target sound component contained in the audio signal from the spectrum of the non-stationary noise. A second noise suppressor performs a filtering process using the filtering factor on the audio signal after processing of the first noise suppressor. An index calculator calculates a kurtosis change index representing an extent of change of kurtosis in a frequence distribution of magnitude of the audio signal between the kurtosis observed when processing of the first noise suppression part is performed and the kurtosis observed when processing of the second noise suppression part is performed. A factor adjuster variably controls the subtraction factor according to the kurtosis change index.

摘要： A transmission line having a slot line with a slot formed on a front surface electrode on a dielectric substrate, and two such slot lines are positioned with the front surface electrodes separated from one another with a gap therebetween. A slot resonator with one end open at the gap side is provided at the front edge side of each slot line, and these slot resonators are positioned so as to be capable of coupling to one another. A slot stub which is branched out from the gap side is provided on each front surface electrode. Thus, leakage of a high-frequency signal in the gap can be suppressed with the slot stub.
