  • Patent number: 9019609
    Abstract: An objective of the present invention is to alleviate streaky display unevenness that occurs in liquid crystal display elements when feeding optical function film from a continuous roll having score lines in the width direction thereof and bonding the optical function film on a liquid crystal panel. A continuous roll comprises an optical film laminate (15) that is in the form of a continuous web wound into a roll and comprises at least an optical function film (10) and a carrier film (13) releasably placed on the optical function film (10). The optical function film (10) is divided into a plurality of cut pieces by score lines (16) formed along a widthwise direction of the optical film laminate (15). It is possible to resolve the problem by making the bending rigidity per unit longitudinal length of the optical function film fall within a specific range.

  • Patent number: 8874959
    Abstract: A CPU I/F decodes a signal transmitted from a CPU to a target location, and transmits the decoded signal to a mediating module mediating with the target location and to an access log recording unit. The access log recording unit generates an access log using the signal received from the CPU I/F, and stores the access log in an internal RAM. A DMA stores the access log stored in the internal RAM in a nonvolatile RAM when a system controller detects any occurrence of an error in the CPU.

  • Publication number: 20140306703
    Abstract: An object of the present invention is to suppress artifacts generated by correction of spectral distortion induced by eddy currents in MRI devices with a simple method, and thereby improve accuracy of the correction. In the eddy current correction processing for correcting spectral distortion caused by an eddy current using phase values of FID signals of a substance showing higher signal intensities compared with a metabolite as an object of measurement, phase jumps of the phase values used for the correction are corrected beforehand. In the correction of the phase jumps, small phase change amount points are identified by using primary time differential values of the phase values, and the other points are identified as a phase jump generation region. Then, the primary time differential values corresponding to the identified phase jump generation regions are excluded.
