摘要:
A spindle motor comprises a stationary shaft, a rotor hub rotatably mounted by ball bearings to the stationary shaft, and annular sealing members disposed between the outer surface of the stationary shaft and the inner side of the rotor hub axially outwardly of the ball bearings. The sealing member is directly fitted onto the outer race of the corresponding ball bearing. The outer race of each ball bearing is high precision finished so that the sealing member is definitely coaxial with the stationary shaft regardless of the finishing accuracy on the inner side of the rotor hub. Accordingly, the radial distance between the inner side of the sealing member and the outer surface of the stationary shaft can be minimized with high precision offering an excellent labyrinth effect.

摘要:
A promoter for a polycondensation reaction used together with a catalyst in a polycondensation reaction, the promoter for a polycondensation reaction comprising a pyrogallol compound having a benzene ring of which three hydrogen atoms adjacent to each other are substituted by hydroxyl groups; and a polycondensation resin obtained by polycondensing raw material monomers using the promoter as defined above and the catalyst. A polycondensation resin can be produced using the promoter of the present invention together with a catalyst in a polycondensation reaction, and the polycondensation resin can be used in various applications including, for example, films, sheets, fibers, toner materials for electrophotography, and the like.

摘要:
A content storage device is in a content storage processing system, which includes a plurality of content storage devices connect to one another via a network. The content storage device transmits metadata corresponding to a specified original content and collects metadata that is relevant to the metadata corresponding to the original content from other content storage devices. The content storage device adds information included in the collected metadata to the metadata corresponding to the original content to enrich information included in the metadata corresponding to the original content.

A content playback device includes: a video playback unit which plays content having plural scenes; an object appearance information acquisition unit which acquires, for each of the plural scenes, object appearance information of each of one or more objects which appear in the content by analyzing metadata which includes appearance scene data for identifying the one or more objects appearing in at least one of the scenes, the object appearance information indicating whether the object appears at least in or after the scene; and a display unit which presents the object appearance information acquired for a scene being played, when the video playback unit is playing the content.
摘要:
An information classification device of the present invention includes a classifying unit (3) classifying two or more content items into groups, each including a capturing time information item and a capturing location information item. The number of the groups is indicated in the number-of-groups information. Based on the capturing location information items, the classifying unit (3) merges each of the content items into the groups to generate first groups. In the case where there is a second group found among the generated first groups and including content items of which temporal continuity is not ensured, based on the capturing time information items, the classifying unit (3) divides the second group into sub-groups each including a content item of which temporal continuity is ensured, and adjusts the distance between each of two or more of the content items included in the sub-groups so that the sub-groups become distant from each other.
