  • Patent number: 9477124
    Abstract: A display device includes a display panel, a flexible circuit board, a signal transmission board, a driver component, a frame-shaped member, and a heat dissipation member. The signal transmission board is configured to transmit signals to the flexible circuit board. The driver component is mounted on the flexible circuit board and configured to process the signals from the signal transmission board and supply the processed signals to the display panel. The frame-shaped member retains the liquid crystal panel by holding edges of the display panel on a display surface side. The heat dissipation member has higher thermal conductivity than the frame-shaped member and embedded in a portion of the frame-shaped member. The heat dissipation member includes a contact portion that projects toward the signal transmission board and a distal end that is in contact with a portion of the flexible circuit board on which the driver component is mounted.

  • Publication number: 20160108395
    Abstract: Chimeric single-stranded polynucleotides and double-stranded antisense agents useful for modifying the expression of a target gene by means of an antisense effect are disclosed. The chimeric single-stranded antisense polynucleotide and double-stranded antisense agents comprise a central nucleotide region flanked by a first 5?-wing region and a first 3?-wing region of modified nucleotides, which are themselves flanked by a second 5?-wing region and/or a second 3?-wing region of nucleotides that have a low affinity for proteins and/or that have higher resistance to DNase or RNase than a natural DNA or RNA and are missing in a cell when the chimeric polynucleotide delivered. The double-stranded antisense agent further comprises a complementary strand annealed to the antisense strand. The polynucleotide can be used to modify RNA transcription levels, miRNA activity, or protein levels in cells.

  • Patent number: 9279186
    Abstract: A metallic material containing both a second constituent and a third constituent having positive and negative heats of mixing relative to a first constituent, respectively, and including a compound, an alloy or a nonequilibrium alloy having a melting point that is higher than the solidifying point of a metal bath made of the first constituent is placed in the metal bath. The metal bath is controlled to a temperature lower than a minimum value of a liquidus temperature within a range of compositional variations in which the amount of the third constituent in the metallic material decreases down to a point where the metallic material becomes substantially the second constituent so that the third constituent is selectively dissolved into the metal bath.

  • Publication number: 20150367883
    Abstract: A control system calculates inputs to a control target that has m inputs and n outputs (m=n, each of m and n is a natural number that is more than one), while designating a plurality of combinations of the inputs and the outputs. A feedback controller calculates, with respect to each designated combination, a control input to a non-interference controller based on a difference between a target value and a current value of the control quantity to make the current value follow the target value. The non-interference controller executes, with respect to each designated combination, a non-interference control to reduce influence due to mutual interference between n control quantities. This reduces the number of combinations of the inputs and the outputs, the combinations whose mutual interference needs considering; thereby, the non-interference control may be easily achieved.

  • Publication number: 20150338903
    Abstract: Upon completion of rewriting of a page of a document, a display apparatus having a display unit with memory switches to a low power consumption mode without rewriting the display on a display unit, and stops power supply to the display unit. When a page updating operation is performed in the low power consumption mode, the display apparatus supplies power to the display unit, and rewrites the display screen with the screen of the next page.

  • Publication number: 20150333544
    Abstract: An electricity distribution device is connected to a system power supply and a battery pack, and includes: a primary power converter circuit converting DC electric power discharged from the battery pack into electric power supplied to the load; a first switch switching conducting and non-conducting states between the primary power converter circuit and the load; and a control circuitry controlling the first switch to switch the conducting and non-conducting states between the primary power converter circuit and the load. The primary power convertor circuit consumes DC electric power discharged from the battery pack, in a state where the first switch switches the non-conducting state between the primary power convertor circuit and the load, and a current value is acquired when discharging from the fully-charged state to an empty state. The fully-charged capacity of the battery pack is measured using the acquired current value.

  • Publication number: 20150317947
    Abstract: When an area to be rewritten includes a first area including a character and a second area including an image object, a control unit outputs, to a controller, a display update instruction and information indicating the second area. Upon acquisition of the instruction and the information indicating the second area, first, the controller updates the first area and the second area by a first method. Next, the controller updates the second area by a second method that requires a longer updating time than the first method.
