According to one embodiment, a magnetic disk device includes a disk, a head including a write head configured to write data on the disk, a first read head, and a second read head each configured to read data from the disk, and a controller configured to detect a first error of each track pitch corresponding to each track of the disk on the basis of a first gap in a radial direction between the first read head and the second read head at each position in the radial direction of the disk, write a servo pattern on the disk on the basis of a first correction value used to correct the first error, and position the head on the basis of the servo pattern.

Magnetic disk device and head positioning method

Provided is a knowledge extracting apparatus for extracting knowledge information related to a knowledge-extraction target from an electronic document distributed continually in a state where the electronic document is not associated with the knowledge-information extraction target. A knowledge extracting apparatus according to one embodiment is a knowledge extracting apparatus including: an information receiving section for receiving an electronic document; a knowledge extracting section for extracting a concept from the electronic document based on a target word to extract knowledge information and a clue word to extract knowledge information and forming knowledge information in which the concept thus extracted and the target word are associated with each other; a storage section for storing the knowledge information thus extracted; and an information analysis section for, after the knowledge information is stored, analyzing the electronic document based on the knowledge information in the storage section.

Forming knowledge information based on a predetermined threshold of a concept and a predetermined threshold of a target word extracted from a document

A lock device includes a base, a first rotation member, a second rotation member, a first elastic member, and a second elastic member. Protrusions are provided on one of the base and one of the first rotation member and the second rotation member. The protrusions are protruded in a direction parallel to the rotation axis of the first rotation member. An end of one of the first elastic member and the second elastic member is fixed to the protrusions. The protruding length in the rotation axis direction of the protrusions is longer than the length in the rotation axis direction of one of the first elastic member and the second elastic member.

Lock device

A locking device provided with: a striker-contact member () which is positioned on a hook () and is abutted against a striker being entered the groove () of the hook () so as to sandwich the striker in cooperation with the groove () of the hook (); and a spring (hook-biasing member) () that urges the hook () in the unlocked position direction via the striker-contact member () and that urges the striker-contact member () in a direction a direction to be abutted against the striker.

Locking device

According to one embodiment, there is provided a charging management system. Based on an estimated duration from a time when an electric vehicle having arrived at each of a charging facilities starts charging until the charging is complete, the system determines the charging facility a charging facility utilization of which is to be recommended to be one of the charging facilities related to a path to a destination which has a shortest maximum wait time from a time when a plurality of electric vehicles arrive at the charging facility until the charging is complete, and reports information indicative of the determined charging facility to the electric vehicle not having arrived at the charging facility.

According to an embodiment, there is provided a consumed power amount estimation apparatus including an estimation unit configured to estimate a power amount necessary for an electric vehicle having a similar power consumption tendency to run, based on a parameter used to compensate for information affecting power consumption by running of the electric vehicle based on consumed power amount information of each of a plurality of electric vehicles having similar power consumption tendencies.

Characteristics of a magnetic material are improved without using a heavy rare earth element as a scarce resource. By incorporating fluorine into a magnetic powder and controlling the crystal orientation in crystal grains, a magnetic material securing magnetic characteristics such as coercive force and residual flux density can be fabricated. As a result, the resource problem with heavy rare earth elements can be solved, and the magnetic material can be applied to magnetic circuits that require a high energy product, including various rotating machines and voice coil motors of hard discs.
