A radar apparatus includes a detection unit to detect objects within a scan range based on a reflected wave received with respect to a transmission wave and to output detection results of the objects, and an adjusting unit to narrow the scan range so as not to detect an object other than a target object, when the detection results include the object other than the target object detected in the scan range within a predetermined time. The adjusting unit judges an object having a velocity less than a first value as the object other than the target object.

Radar apparatus and computer-readable storage medium

The present invention relates to an antenna apparatus capable of multifrequency resonance and realizes downsizing and multifrequency resonance. The present invention relates to an antenna apparatus capable of multifrequency resonance or a radio communicating apparatus (e.g., portable phone) including the antenna apparatus; toward a feed element connected to and supplied with electricity from a feeding unit of a circuit substrate (printed circuit substrate), a non-feed element is disposed with over the circuit substrate or outside the circuit substrate; and the feed side or the open side of the feed element is electromagnetically coupled to the non-feed element to enable resonance in the frequency band of the non-feed element in addition to resonance in the frequency band of the feed element.

Antenna apparatus and radio communicating apparatus

An antenna that provides three resonance frequencies includes a dielectric, and an electrically conductive antenna element arranged on a dielectric, the antenna element branches into three parts and being connected to a single feeding point, and at least two of the three parts being electromagnetically coupled with each other.

Antenna and wireless apparatus

A digital X-ray apparatus forms a latent image of an object on a photostimulable phosphor plate as an energy distribution pattern using X-ray energy and reads the latent image using an excitation light beam. A plate, of a material which does not transmit the excitation light beam, has holes formed therein with photostimulable phosphor positioned in the holes, the photostimulable phosphor emitting a fluorescent light when irradiated by the excitation light beam, the emitted light beam gathered and a corresponding signal produced. The excitation light beam reflected from the photostimulable phosphor plate is also gathered and a signal responsive thereto also is produced. A method of production by stacking and bonding plural metal sheets having appropriate patterns of holes therein with the photostimulable phosphor and a transparent protection film layer thereon provides the structure of the photostimulable phosphor plate.

Photostimulable phosphor plate and photostimulable phosphor reader

In a digital X-ray apparatus for exposing an X-ray transmitted through an object onto a photostimulable phosphor plate, for scanning the photostimulable phosphor plate by an excitation beam, and for obtaining an X-ray image, the digital X-ray apparatus includes a switch unit connected to a storage unit and switching between a standard photographing mode and an actual photographing mode; a correction coefficient conversion unit converting the X-ray image data to an image data having a standardized lightness; a first storage unit storing an initial correction coefficient after standardization in the correction coefficient conversion unit; a second storage unit storing a correction coefficient after standardization in the correction coefficient conversion unit; a detection unit comparing a value of the correction coefficient from the second storage unit with a value of the initial correction coefficient from the first storage unit, and detecting whether or not a difference between the value of the correction coefficient at each picture element and the value of the initial correction coefficient at each picture element exceeds a predetermined threshold value; and a generation unit displaying a number of abnormal picture elements detected by the detection unit and generating an alarm message when the number of abnormal picture elements exceeds a predetermined number, the predetermined number being defined by a ratio of the number of abnormal picture elements to the number of all the picture elements.
