摘要： 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.

摘要： An object of the invention is to obtain a magnetic resonance spectroscopic image to which the MAC summation is applied with high accuracy and in short time, even though a phase characteristic distribution of the MAC has a spatial non-uniformity, in the MRSI measurement using a magnetic resonance imaging apparatus provided with a MAC. Using a non-water-suppressed image signal with high SNR, obtained in the non-water-suppressed measurement (a reference measurement) without water suppression, a correction value for correcting the phase distortion for the MAC summation is calculated on each pixel in each coil. After correcting a phase on each pixel in each coil of a main-scan image signal measured under suppressing water (water-suppressed image signal) using the corrective value, signal adding operation (summation) is performed. Then, a phase correction in a spectrum-axis is to be performed on the summed spectrum signal.

摘要： When the nucleic-acid base sequence of A, C, G, and T (or U) is determined by interpreting fluorescent-light intensity waveform data acquired by measuring nucleic-acid fragments, it is desirable to determine, with a high-accuracy, the base sequence at a location at which the data interpretation is difficult. In order to accomplish this object, the data interpretation is performed by making reference to information acquired by performing the statistical processing to plural pieces of fluorescent-light intensity waveform data corresponding to already-known base sequences. This method allows the determination of the nucleic-acid base sequence at the above-described location.

摘要： The present invention provides a magnetic resonance imaging system capable of performing spectrum measurement even when a magnetic resonant frequency changes during MRS measurement. A time-varying rate of a water magnetic resonant frequency is measured in advance before the MRS measurement. The amount of change in water magnetic resonant frequency during the MRS measurement is predicted from the measured time-varying rate. With the predicted value as the reference, a transmission frequency of an RF magnetic field irradiated in a signal suppression pulse sequence, a transmission frequency of an RF magnetic field for excitation and inversion and a received frequency at the detection of a magnetic resonance signal in a sequence of the MRS measurement are respectively set. A high-precision spectrum measurement is hence enabled.

摘要： First, prior to the measurement of the magnetic resonance spectroscopic image, the gradient polarity of a gradient magnetic field to be applied to an object is inverted periodically. This makes it possible to measure a multi-gradient echo type magnetic resonance signal that has been subjected to the influence of an eddy current. Then, from the magnetic resonance spectrum obtained therefrom, a peak of the frequency component is extracted that corresponds to a hydrogen nucleus in the water molecule. Finally, using a static magnetic field homogeneity degree-adjusting unit, a shimming current to be flowed through a shimming coil and/or an offset current to be flowed through a gradient magnetic field generating coil are adjusted so that the width of the peak becomes narrow, thereby enhancing the degree of the static magnetic field homogeneity.
