External electrodes 12, 13 each have a second base conductor film 12a, 13a and a surface conductor film 12b, 13b, and the wraparound locations 12b1, 13b1 of each surface conductor film 12b, 13b have insertion parts 12b2, 13b2 that fill in the clearances CL. The multilayer ceramic capacitor can mitigate deterioration in moisture resistance.

Abstract: In an X-ray diagnostic apparatus of one embodiment, an image data generator sequentially generates X-ray images based on X-rays transmitted through a subject. An image processor executes: first processing where, in response to an instruction to start correction processing, a position of a target contained in a predetermined X-ray image is obtained as a reference position; and second processing where corrected images in which positions of the target are set at the reference position are sequentially generated from newly generated X-ray images. An image data storage unit stores therein information on a reference position with respect to each set of conditions of manipulation on the subject. Upon receiving the instruction to start correction processing, the image processor executes the second processing by using information on the reference position stored in the image data storage unit, in accordance with a set of the conditions of manipulation on the subject.

Abstract: An X-ray diagnostic apparatus of an embodiment includes processing circuitry. The processing circuitry acquires two medical images, a moving distance of a region of interest between the medical images corresponding to a distance derived from a parallax angle. The processing circuitry causes a display to display a stereoscopic image based on the medical images.

Abstract: According to one embodiment, an X-ray diagnostic apparatus includes an input circuit, an X-ray tube and an X-ray detector, and processing circuitry. The input circuit converts an input operation into an electric signal and output the electric signal. The X-ray tube and the X-ray detector image X-ray images of an object. The processing circuitry detects positions of feature points of devices from the X-ray images; generates corrected images by motion correction of the X-ray images when an electric signal corresponding to an input operation for selecting a predetermined device has been input from the input circuit; and displays the corrected images as the moving image in real time. The motion correction is performed based on positions of a feature point of the selected device. At least a part of the selected device nearly stops when the X-ray images have been displayed, by the motion correction.

Abstract: A laminated ceramic capacitor has a capacitor body of roughly a rectangular solid shape defined by the length, width, and height, as well as a concaved part formed at and along the edges of one side and the other side in the height direction. An external electrode has a base conductor layer whose height-direction wrap-around part is formed inside the concaved part, and a main conductor layer whose height-direction wrap-around part is formed continuously over the height-direction wrap-around part of the base conductor layer through the planar part, except for the concaved part, of one side and the other side of the component body in the height direction. The height-direction wrap-around part of the main conductor layer has a planar connecting area constituted by a surface area over the height-direction wrap-around part of the base conductor layer and a surface area over the planar part of the component body.

Abstract: An X-ray diagnostic apparatus of an embodiment includes an image generator, a detection unit, and an irradiation control unit. The image generator successively generates X-ray images based on X-rays emitted from an X-ray tube and transmitted through a subject. The detection unit detects a position of a predetermined target included in the successively generated X-ray images. The irradiation control unit identifies, based on the detected position of the predetermined target, a region in which the predetermined target can be visualized in the X-ray images, and performs control to reduce an X-ray irradiation dose to a region other than the identified region.

Abstract: According to one embodiment, a medical image diagnostic apparatus includes an X-ray tube, an X-ray detector, storage circuitry, slice image generation circuitry, a display. The X-ray tube generates X-rays from a predetermined focus. The X-ray detector detects X-rays which have been generated by the X-ray tube and passed through an object placed on a top plate. The storage circuitry stores volume data about the object. The slice image generation circuitry generates slice images corresponding to planes each including the focus based on the volume data and a relative position of the focus with respect to the top plate. The display displays the slice images.

Abstract: The magnetic material for magnetic refrigeration according to the present invention has an NaZn13-type crystalline structure and comprises iron (Fe) as a principal element (more specifically, Fe is substituted for the position of “Zn”) and hydrogen (H) in an amount of 2 to 18 atomic % based on all constitutional elements. Preferably, the magnetic material for magnetic refrigeration preferably contains 61 to 87 atomic % of Fe, 4 to 18 atomic % of a total amount of Si and Al, 5 to 7 atomic % of La. The magnetic material for magnetic refrigeration exhibits a large entropy change in a room temperature region and no thermal hysteresis in a magnetic phase transition. Therefore, when a magnetic refrigeration cycle is configured using the magnetic material for magnetic refrigeration, a stable operation can be performed.
