Abstract: An information processing apparatus as one aspect of the present invention detects a predetermined behavior of a person, specifies first tracking information of a first person for which the predetermined behavior has been detected and second tracking information of a second person for which it is estimated that replacement has occurred during movement of the first person, generates third tracking information based on the first tracking information and the second tracking information, and determines whether or not the first person satisfies a predetermined condition based on a detection result of the predetermined behavior corresponding to the third tracking information.

Abstract: An information processing apparatus determines tracking information that is a target of collation processing for performing association with person information from among a plurality of items of tracking information corresponding to a plurality of persons detected from a video image frame based on a feature amount of each of the plurality of persons, and executes collation processing in which person information to be associated with the tracking information that is a target of the collation processing is identified based on a similarity between a feature amount of a person corresponding to a tracking information determined to be a target of the collation processing and a plurality of feature amounts stored in association with a plurality of items of person information in a storage device.

Abstract: A multi-plate clutch system includes an outer clutch member having a plurality of first clutch plates thereon, a central spool having a plurality of second clutch plates thereon interspaced with the first clutch plates. The clutch system also includes a cam mechanism including a protruding cam and a recessed cam. The protruding cam and the recessed cam respectively include first inclined faces and second inclined faces, which are inclined in the same direction with respect to the circumferential direction. The protruding cam is thus brought into a point contact with the recessed cam during clutch engagement. As such, the multi-plate clutch system can maintain constant variable characteristics of the clutch capacity even when there is a variation in processing accuracy at the time of the production.

Abstract: A clutch for effectively prevents a clutch outer from tilting at the time when torque is varied. The clutch includes damper springs for transmitting, to a clutch outer, torque inputted to a driven gear, and a thrust washer for regulating positional change of a position of the clutch outer with respect to the driven gear in a direction of the shaft axis. The thrust washer is disposed between the driven gear and the clutch outer in an axial direction. The thrust washer is disposed only outward of the damper springs in a radial direction.

Abstract: A relief valve includes a cylindrical valve housing attached to an engine body continuously with a relief passage and an outlet provided in an axially intermediate portion thereof. A valve body is slidably fitted to the valve housing so as to allow the relief passage to communicate with the outlet as an oil pressure in the relief passage becomes equal to and exceeds a predetermined oil pressure. A skirt includes an upper end portion fixed to the valve housing above the outlet for guiding oil discharged from the outlet downward. The relief valve exerts a reliable defoaming function in response to an increase in the oil discharged from the outlet and an increase in an ejection pressure thereof while avoiding an increase in the size of the skirt. An annular recessed portion is formed on an outer circumference of the intermediate portion of the valve housing below the outlet.

Abstract: A generator is provided inside the casings of a power unit which is fitted to the rear end of a crank shaft. The generator has a stator provided to a generator cover detachably fitted to cover a rear opening of the casing. A harness extends from the stator and is led outside through a grommet provided between the joining faces of the casing and the generator cover. A space is formed behind the generator cover to insert a tool such as an impact wrench with the power unit left mounted on the vehicle body. It is possible to detach and maintain the generator only by detaching the generator cover while leaving the power unit mounted on the vehicle body.
