A vehicle number identification device includes a registration-number-information acquisition part configured to acquire registration number information associated with an identification media installed in a vehicle; a number-plate-image acquisition part configured to acquire a number-plate image of the vehicle; an OCR processing part configured to acquire OCR resultant information representing a result of an optical character recognition with respect to the number-plate image; an estimation processing part configured to input the number-plate image into a machine-learning model and to acquire estimation result information output from the machine-learning model; and a matching determination part configured to determine whether at least two types of information out of the registration number information, the OCR resultant information, and the estimation result information indicate a same vehicle number and to identify the same vehicle number as a vehicle number of the vehicle.

A number plate information specifying device includes an image acquisition unit that acquires a number plate image, a feature point extraction unit that extracts a feature point from the number plate image, a degree of similarity calculation unit that references a learning data set in which a plurality of feature points are recorded in association with a plurality of pieces of number plate information and calculates degrees of similarity for the feature points recorded in the learning data set that correspond to the feature point extracted from the number plate image, a vote value calculation unit that, on the basis of the degrees of similarity, calculates vote values for the pieces of number plate information recorded in the learning data set, and a specifying unit that specifies the piece of number plate information that has the highest vote value as the number plate information displayed in the number plate image.

A map matching device includes: a candidate spot extraction unit that extracts candidate spots onto a link based on position measurement points; a movement cost determination unit that determines the movement cost of a combination of links connecting one of first candidate spots extracted based on one position measurement point to one of second candidate spots extracted based on another position measurement point, the movement cost determined separately for each combination of a first and a second candidate spot; a movement possibility judgment unit that judges, for each combination of first and second candidate spots, whether a moving body can move from the first to the second candidate spot, based on the movement cost; and a matching spot determination unit that determines, as the position of the moving body on the map, one of the candidate spots included in a combination for which movement was determined to be possible.

A thermal assisted magnetic recording head of the present invention has an air bearing surface (ABS) opposite to a magnetic recording medium, a core that can propagate laser light as propagating light, a plasmon generator that includes a generator front end surface facing the ABS, and a main pole that faces the ABS and emits magnetic flux to the magnetic recording medium. The plasmon generator is opposite to a part of the core and extends to the generator front surface, is coupled with a portion of the propagating light that propagates through the core in the surface plasmon mode to generate a surface plasmon, propagates the surface plasmon to the generator front end surface, and generates near-field light (NF light) at the generator front end surface to irradiate the NF light to the magnetic recording medium. The ABS has a protrusion that is closer to the leading side than the generator front end surface in the down track direction, and that protrudes more toward the magnetic recording medium than the generator front end surface upon operation of the thermal assisted magnetic recording head.

A magnetic head includes a main pole, a write shield, and a return path section. The write shield includes first and second shield portions located on opposite sides of the main pole in the track width direction. The return path section includes first and second yoke portions located on opposite sides of the main pole in the track width direction. The first yoke portion is connected to the first shield portion. The second yoke portion is connected to the second shield portion. A coil surrounds at least part of the entire outer periphery of the main pole when viewed from a medium facing surface.

Magnetic head for perpendicular magnetic recording having a write shield

A trailing shield is provided on a trailing side of a magnetic pole with a non-magnetic gap layer in between, and an intermediate layer having negative uniaxial magnetocrystalline anisotropy is provided between the non-magnetic gap layer and the trailing shield. The intermediate layer has a magnetic property in which an easy axis of magnetization is provided in an in-plane direction and thus magnetization is likely to occur in that direction, whereas a difficult axis of magnetization is provided in a direction intersecting the in-plane direction and thus magnetization is less likely to occur in that direction. Accordingly, magnetic flux becomes difficult to excessively flow from the magnetic pole into the trailing shield.
