摘要:
Modified natural graphite particles intended for forming a negative electrode material for a nonaqueous electrolyte secondary battery are characterized by having a circularity of at least 0.93 and at most 1.0 and a surface roughness of at most 1.5% with respect to the length of the particles. These modified natural graphite particles are obtained by a manufacturing method including a step of applying an impact force to natural graphite particles for pulverization and spheroidization to obtain intermediate particles having a circularity of at least 0.93 and at most 1.0, and a step of carrying out surface smoothing of the resulting intermediate particles by mechanical grinding treatment to obtain the modified natural graphite particles.

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.

As imaging devices are miniaturized, and optical devices are miniaturized, lens moving mechanisms are also miniaturized. Thus, position sensors for them are required to be miniaturized and have high accuracy at low cost. A magnet of a pillar shape and a yoke which move in the X axis direction with respect to a magnetic field detection element are provided, and a shape of a cross section of the yoke which is orthogonal to a longitudinal direction of the magnet changes along the longitudinal direction.

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.

摘要:
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.

Disclosed herein is an image processing apparatus including a color-flicker detection processing section configured to detect generation of color flickers from a plurality of images taken at different exposure times, wherein the color-flicker detection processing section: acquires a ratio of any specific one of a plurality of color signals of the taken images to another one of the color signals; obtains an evaluation value of the color flickers from the acquired ratio; and determines whether or not the color flickers have been generated on the basis of the magnitude of the evaluation value.
