  • Patent number: 10624592
    Abstract: An X-ray diagnosis apparatus according to an embodiment includes a calculating unit and a control unit. The calculating unit that calculates an angle between a specified position specified in an ultrasonic image generated through transmission and reception of ultrasonic waves by an ultrasound probe and a predetermined position in a radiographic space where a subject is radiographed based on information on a relative position between the radiographic space and a scanning space where the subject is scanned by the ultrasound probe. The control unit that controls an arm to move so that the subject is radiographed at the angle calculated by the calculating unit.

  • Patent number: 9871152
    Abstract: To provide a solar cell that reduces occurrence of a defect and has high photoelectric conversion efficiency. The solar cell includes a silicon substrate such as an n-type single-crystal silicon substrate single crystal with pyramid-shaped irregularities P formed thereon, and an amorphous or microcrystal semiconductor layer formed on the single-crystal silicon substrate. A flat part F is formed in a valley portion of the pyramid-shaped irregularities P provided on a surface of the single-crystal silicon substrate. With this configuration, a steep angle of 70° to 85° of a concave portion formed by a substantially (111) surface can be widened to between 115° and 135°. Accordingly, a change of atomic step morphology attributable to a rounded shape can be eliminated, thereby enabling to reduce epitaxial growth and defects in the amorphous or microcrystal semiconductor layer.

  • Patent number: 5892244
    Abstract: The present invention relates to a field effect transistor (FET element) in which a .pi.-conjugated polymer film serving as a semiconductor layer is manufactured by first forming a .pi.-conjugated polymer precursor film using a .pi.-conjugated precursor which is soluble in a solvent and then changing the precursor polymer film to the .pi.-conjugated polymer film. A liquid crystal display apparatus uses the FET element as an active drive element. A large number of the FET elements can be manufactured on a large area substrate at the same time at lost cost and operate stably. A large current flow between the source and drain can be significantly modulated by a voltage applied to the gate of the FET element.
