  • Patent number: 8744043
    Abstract: A radiation image capturing device includes a radiation image capturing unit, a diaphragm unit, and a control unit. The radiation image capturing unit captures a radiation image based on radiation transmitted through a subject. The diaphragm unit has an opening region that is configured to transmit a part of the radiation emitted from a radiation source and an area thereof is changeable, and the diaphragm unit is configured such that a transmission dose of the radiation decreases as a distance from a circumferential part of the opening region increases. The control unit controls the diaphragm unit such that direct rays of the radiation are irradiated onto a predetermined region of the subject.

  • Patent number: 8400727
    Abstract: According to one embodiment, a recording device comprises: a recording medium, an arm, a positioning module, a self-servo write clock generator, and an on-track module. The positioning module positions the arm at a position at which the electromagnetic transducer detects a rotational synchronization component of an intermediate pattern comprised in the recording medium. The self-servo write clock generator generates a self-servo write clock based on the detected rotational synchronization component. The on-track module positions the electromagnetic transducer to the intermediate pattern serving as a position for starting self-servo write based on the generated self-servo write clock. Until the on-track module appropriately completes the positioning, the self-servo write clock generator sequentially changes a decoding gate interval corresponding to the intermediate pattern in accordance with the rotational synchronization component, and captures a spiral reproduction waveform.
