    • Providing a zoom lens system having excellent optical performance with a high zoom ratio, an imaging apparatus, and a method for zooming the zoom lens system. The system including, in order from an object, a first group G1 having negative refractive power, a second group G2 having positive refractive power, a third group G3 having negative refractive power, and a fourth group G4 having positive refractive power. An aperture stop S is disposed between the second group G2 and the fourth group G4. Upon zooming from a wide-angle end state to a telephoto end state, each group is moved such that a distance between the second group G2 and the third group G3 increases, a distance between the third group G3 and the fourth group G4 decreases, and the aperture stop S is moved together with the third group G3. Given conditions are satisfied.
    • 提供具有高变焦比的优异光学性能的变焦透镜系统,成像装置和用于变焦变焦透镜系统的变焦方法。 该系统从物体起依次包括具有负折光力的第一组G1,具有正屈光力的第二组G2,具有负折光力的第三组G3和具有正屈光力的第四组G4。 孔径光阑S设置在第二组G2和第四组G4之间。 在从广角端状态变焦到望远端状态时,各组移动使得第二组G2和第三组G3之间的距离增加,第三组G3和第四组G4之间的距离减小,并且 孔径光阑S与第三组G3一起移动。 给定条件满意。

    • A management system for managing storage systems, having first correspondence information concerned with correspondence of copy pairs with copy groups as setting of remote copying of data in logical volumes of the storage systems, and second correspondence information concerned with correspondence of physical paths and logical paths between the storage systems with the copy groups, wherein when failure information designating a certain physical path is received, a copy group affected by failure in the certain physical path is specified and displayed by referring to the first correspondence information and the second correspondence information. Consequently, physical paths can be monitored from the viewpoint of remote copying.
    • 一种用于管理存储系统的管理系统,具有与复制组的对应关系的第一对应信息作为存储系统的逻辑卷中的数据的远程复制的设置以及与物理路径和逻辑路径之间的对应关系相关的第二对应信息 具有复制组的存储系统,其中当接收到指定某个物理路径的故障信息时,通过参考第一对应信息和第二对应信息指定并显示受特定物理路径中的故障影响的复制组。 因此,可以从远程复制的角度监视物理路径。

    • In a bush (10) which relatively-rotatably supports a journal shaft (1) around its central axis by housing the journal shaft (1) in a formed bearing hole (11), the bush 10 includes an oil supply groove (16) formed spirally to supply lube oil to an inner surface of the bearing hole (11) which contacts to the journal shaft (1) when the journal shaft relatively rotates. A ratio of an area of the oil supply groove (16) to the inner surface area of the bearing hole (11) is equal to or less than 30%. A product of a distance in the central axis direction and a distance in the circumferential direction of the journal shaft (1) between the oil supply groove (16) in next to each other on the inner surface of the bearing hole (11) is within 50 to 300 mm2 range.
    • 在通过将轴颈轴(1)容纳在形成的轴承孔(11)中而相对地可旋转地支撑轴颈轴(1)的衬套(10)中,衬套10包括形成的供油槽(16) 螺旋地将润滑油供给到当轴颈轴相对旋转时与轴颈轴(1)接触的轴承孔(11)的内表面。 供油槽(16)的面积与轴承孔(11)的内表面积的比例等于或小于30%。 在轴承孔(11)的内表面上彼此相邻的供油槽(16)之间的轴心方向上的距离和轴颈轴(1)的周向距离的乘积在内 50至300 mm2范围。
