    • When data of plural original images having different echo times are acquired to produce water/fat separated images by performing an processing operations in an MRI apparatus, a partial region of the original image data is specified and the specified region is subjected to the water/fat separation processing. Since noise components included in the specified region are fewer than those in the original image data, errors occurring due to noise components during unwrapping and other such processing operations can be reduced and image quality degradation be suppressed. Therefore, water/fat separated images having an excellent image quality can be produced. When echoes having different echo times are generated, rewind pulses are applied ahead of the readout gradient magnetic fields to equalize the polarities of the readout gradient magnetic fields. Consequently, influence of application of gradient magnetic fields on echo signals can be suppressed and the accuracy of water/fat separation can be improved.
    • 获取具有不同回波时间的多个原始图像的数据,以通过在MRI装置中执行处理操作来产生水/脂肪分离的图像,指定原始图像数据的部分区域,并且指定区域经受水/脂肪 分离处理。 由于包含在指定区域中的噪声分量比原始图像数据中的噪声分量少,因此可以减少由于解包过程中的噪声成分而产生的误差和其他这样的处理操作,抑制了图像质量下降。 因此,可以产生具有优异图像质量的水/脂肪分离图像。 当产生具有不同回波时间的回波时,在读出梯度磁场之前施加倒带脉冲以均衡读出梯度磁场的极性。 因此,可以抑制梯度磁场对回波信号的影响,并且可以提高水/油分离的精度。

    • In an inertia-press-fit method in which a kinetic energy is applied to at least one of two members in a direction which causes the two members to approach each other, and the two members are press-fitted with each other, an end surface 80 of the first member 10 and a bottom surface 82 of the second member 12 are caused, for stabilizing a relative position of the two members at a time when the press-fitting ends, to butt each other to define the relative position of the two members 10, 12 at the time when the press-fitting ends and, immediately after the butting, at least one of the two members 10, 12 is caused to plastically deform and thereby absorb a remaining kinetic energy of the one of the two members. Thus, the relative position of the two members 10, 12 when the press-fitting ends is stabilized. In the case where respective plastic-deformation capabilities of the two members 10, 12 are great, a maximal value occurs to a graph whose axis of abscissa represents kinetic energy and whose axis of ordinate represents amount of deviation of relative position of the two members. If the respective plastic-deformation capabilities of the two members 10, 12 are so chosen as to decrease the maximal value, then the amount of deviation of the relative position is decreased even though the accuracy of control of the applied amount of kinetic energy may be low.

    • An air belt that is smoothly passed through an anchor and is retracted directly by a retractor is provided. A belt of an air belt includes a single layer portion having a relatively small width, which is formed by a belt, a flat tubular multiple layer portion, and an intermediate portion. The width of the belt is gradually reduced from the multiple layer portion to the single layer portion. A bag is provided only in the multiple layer portion. A distal end of the bag is connected to a tongue, together with a distal end of the belt. The single layer portion is passed through a through anchor and is connected to a retractor. The retractor retracts and extends the belt. The belt is an integral body extending continuously from the single layer portion to a hardly expanding portion of the intermediate portion and the multiple layer portion. An easily expanding portion, which is provided along each side of the intermediate portion and the associated side of the multiple layer portion, is easily expanded sideward when the bag is inflated.

    • The invention is a warp-knitted fabric for an inflatable belt cover for covering an envelope-like belt which composes an inflatable belt that is folded into the shape of a band. The warp-knitted fabric comprises knitting yarns and insert yarns inserted among the knitting yarns. At least two continuous loops are formed by chain-stitching the knitting yarn to compose a base knit structure having multiple vertical loop arrays. Each insert yarn is twined to pass through three or more vertical arrays of loops, thereby significantly improving the fabric's resistance to “run”.
