Abstract: An X-ray diagnosis apparatus according to an embodiment includes: an X-ray generator configured to emit X-rays; an X-ray detector having a detection surface parallel to a first direction and being movable in the first direction and in a second direction orthogonal to the first direction and parallel to the detection surface; and processing circuitry configured to set a plurality of imaging ranges touching each other on the basis of reference information, to cause the X-rays to be emitted from the X-ray generator to each of the plurality of imaging ranges while sequentially moving the X-ray detector, and to generate X-ray images respectively corresponding to the plurality of imaging ranges, on the basis of a detection signal resulting from the X-ray detector detecting the X-rays.

Abstract: The present invention prevents a failure from occurring in an electric vehicle. This electric vehicle is driven by power obtained from a power line via a collector, an energy source mounted on the electric vehicle, or using both thereof, and causes power generated, for example, during braking to be regenerated to the power line via the collector or to be consumed in a load mounted on the electric vehicle. The electric vehicle is characterized by having a function of electrically separating the collector from the power line when the voltage of the power line or a circuit voltage within the electric vehicle deviates from a predetermined range.

Abstract: An information processing system providing a service by using a video captured by an imaging device includes a processor; and a storage storing instructions causing the processor to execute processes of: acquiring video data from the imaging device, estimating an installation angle of the imaging device based on the video data, generating a detection model for detecting a predetermined target from the video based on the installation angle, and providing the service by inputting the video data to the detection model.

Abstract: A pseudo defect sample for adjusting an ultrasonic flaw detection measurement condition to inspect a defect within a target material, the pseudo defect sample comprising a substrate which has a first surface and a second surface opposed to the first surface, the substrate having a counterbore which is formed therein from a side of the first surface to a first depth, and a flat-bottomed hole which is formed from the bottom surface of the counterbore to a second depth and formed in a part of a bottom surface of the counterbore, and a ratio ?/d of an equivalent circle diameter ? of the flat-bottomed hole to the second depth d of the flat-bottomed hole being: 0.08 or more and less than 0.40 when the equivalent circle diameter ? of the flat-bottomed hole is less than 0.3 mm; 0.1 or more and less than 0.60 when the equivalent circle diameter ? of the flat-bottomed hole is 0.3 mm or more and less than 0.4 mm; and 0.11 or more and less than 1.60 when the equivalent circle diameter ? of the flat-bottomed hole is 0.
