摘要： According to one embodiment, an X-ray computed tomography apparatus includes an X-ray tube, a detector, a first DAS, and a second DAS. The radiation detector includes a plurality of detection elements. Each detection element repeatedly detects X-rays generated by the X-ray tube and transmitted through a subject and repeatedly generates an electrical signal corresponding to the energy of the repeatedly detected X-rays. The first DAS acquires the electrical signal detected by part of the imaging region of each detection element in the integral mode. The second DAS acquires the electrical signal detected by the other part of the imaging region of each detection element in the photon count type mode.

摘要： A helical scan type digital recording/reproducing apparatus arranged such that data corresponding to m fields/frames are divisionally recorded in n tracks on a magnetic tape and a slow, still or frame advance reproduction mode is effected in response to an instruction from an external input. The apparatus is equipped with a signal processing circuit coupled to a rotary head for inputting data reproduced from the magnetic tape by the rotary head to store the reproduced data in a memory. In response to the instruction for the slow, still or frame advance reproduction mode, the signal processing circuit outputs a control signal when the data corresponding to one or more frames/fields are stored in the memory. Also included is a servo circuit coupled through a signal line to the signal processing circuit to be responsive to the control signal from the signal processing circuit. The servo circuit controls a capstan motor in accordance with the control signal and the reproduction mode instruction.

摘要： A method for manufacturing a magnetic recording medium including at least a non-magnetic substrate, a soft magnetic underlayer, an orientation control layer that controls an orientation of an immediate upper layer, and a perpendicular magnetic layer in which a magnetization easy axis is mainly perpendicularly oriented with respect to the non-magnetic substrate so as to be laminated one another on the non-magnetic substrate. The perpendicular magnetic layer includes two or more magnetic layers, and each layer is subjected to a crystal growth such that each crystal grain composing each magnetic layer forms a columnar crystal continuous in a thickness direction together with the crystal grains composing the orientation control layer. The orientation control layer, formed of a Co—Cr alloy, is formed by the reactive sputtering using a mixture of a sputtering gas and nitrogen.
