Abstract: An antireflection structure includes an antireflection film provided on a front surface of a substrate. The antireflection film has a plurality of holes that are spatially and periodically arranged and pass through front and back surfaces of the antireflection film. A thickness and a relative dielectric constant of the antireflection film are set according to a relative dielectric constant and a thickness of the substrate and an incident angle ? of an electromagnetic wave. The thickness and the relative dielectric constant of the antireflection film are set for an electromagnetic wave incident at the angle ? so that, for example, an electromagnetic wave reflected by the antireflection film provided on the front surface of the substrate and an electromagnetic wave reflected by a back surface of the substrate deviate from each other by a half wavelength and cancel each other.

Abstract: A radar apparatus includes: a transmitting portion including transmitter elements that emits a transmitting signal as a radar wave toward an object; a receiving portion including receiver elements receiving a reflection signal; and an estimation portion. The estimation portion generates a virtual receiving array including virtual receiver elements. The estimation portion divides the virtual receiving array into identical sub-arrays. The estimation portion generates covariance matrix data for each of the sub-arrays. The estimation portion averages the covariance matrix data for each of the sub-arrays to decorrelate a direct reflection signal from the object and multipath reflection signal among the reflection signal and spatially smooths the reflection signal. The estimation portion resolves the direct reflection signal from the object and the multipath reflection signal. The estimation portion determines the direction of the object.

Abstract: A catheter of the invention includes an elongated flexible tubular main body; a plurality of manipulation wires inserted through the tubular main body and having tips connected to a distal part of the tubular main body; a manipulation-part main body provided at a base end of the tubular main body; and a bending manipulation part. The bending manipulation part has an engagement part engaging with base ends of the manipulation wires, and individually applies pulling force to the plurality of manipulation wires through pulling operations so as to bend the distal part of the tubular main body. The bending manipulation part is provided so as to be movable with respect to the manipulation-part main body. The path lengths of the plurality of manipulation wires from the tips thereof to the engagement part are simultaneously increased or decreased when the bending manipulation part and the manipulation-part main body move relative to each other.

Abstract: A radar apparatus includes a transmitter, a receiver, and a signal processor. The transmitter outputs a radar wave. The receiver includes a plurality of receiving antennas and a plurality of receiving devices. Each of the receiving devices mixes a reception signal from the corresponding receiving antenna with a local signal and outputs a beat signal. The signal processor samples the beat signal while selecting one of the receiving devices in order with a selecting period that is less than a half of a sampling period. The signal processor samples the beat signal with the sampling period and derives position information of a target by pair matching of peaks of a rising-modulation signal and a falling-modulation signal of the beat signal.

Abstract: A radar system for detecting positions of targets using a high resolution algorithm is presented. The number of incorrect target detections due to incorrect estimation of the number of radar reflections is reduced. A two-dimensional (azimuth and distance) peak having maximum power is detected, and a virtual beam formed centering on that peak. If that two-dimensional peak is buried in the virtual beam it is assumed to be a noise peak and removed. This is repeated for all two-dimensional peaks, thereby removing noise peaks and reducing the number of unnecessary target detections. The system can also correctly detect peaks that are close together at a certain resolution but have a power larger than the virtual beam.

Abstract: Provided is a medical instrument which can reliably protect a sub-lumen and a method of manufacturing the medical instrument. In such a medical instrument, a catheter includes a resin tubular main body (sheath), in which a main lumen and a sub-lumen which is disposed on an outer peripheral side of the main lumen and extends along a longitudinal direction of the main lumen, are formed; a reinforcement layer which is disposed between the main lumen and the sub-lumen and surrounds the main lumen; and a wire which is disposed further on an outer peripheral surface side of the tubular main body than the sub-lumen and is disposed so as to surround the outer periphery of the main lumen. The wire is embedded in the tubular main body and supports the outer peripheral surface of the tubular main body.
