  • Patent number: 9460679
    Abstract: A display driving circuit having a shift register is formed on the display panel. The shift register includes a first stage having first and second transistors and a second stage having a third and fourth transistor. A voltage of a control electrode of the first transistor is boosted by a voltage of a first pulse line changing from low to high. In an On state, the second transistor connects the control electrode of the first transistor and a constant voltage line. A voltage of a control electrode of the third transistor is boosted by a voltage of a second pulse line changing from low to high. In an On state, the fourth transistor connects the control electrode of the third transistor and a constant voltage line. The fourth transistor is switched on by a signal from the first stage.

  • Publication number: 20160269616
    Abstract: An imaging apparatus moves a lens in the optical axis direction with respect to the initialization position, and images a subject. The imaging apparatus includes a first lens, a second lens, a driving unit, a first position detection sensor, a second position detection sensor, a third position detection sensor, and a control unit. The driving unit moves the first lens and second lens in the optical axis direction. The first position detection sensor detects the position of the first lens. The second position detection sensor detects the position of the second lens. The third position detection sensor detects the position of the first lens and the position of the second lens. On the basis of the output from the third position detection sensor, the control unit executes the initializing processing of determining the initialization positions of the first lens and second lens.

  • Publication number: 20160155526
    Abstract: Provided is a scintillator panel realizing reduced image unevenness and the like by virtue of having a cushioning layer between a support and a phosphor. The cushioning layer absorbs irregularities on the phosphor layer when the scintillator panel is compression bonded to a planar light-receiving element and thereby allows the phosphor layer to be in contact with the planar light-receiving element without any gaps in the interface. The scintillator panel includes, in the order named, a support, a cushioning layer disposed on a surface of the support, and a phosphor layer deposited on the surface of the cushioning layer, the cushioning layer having a specific thickness, the phosphor layer being configured to be placed into uniform contact with a surface of a planar light-receiving element when the phosphor layer is pressed against the planar light-receiving element by the application of a pressure from the support side.
