Abstract: In a linear actuator, a slide table is attached to a cylinder body via a guide mechanism so as to be movable along the longitudinal direction of the cylinder body. The slide table includes a table body arranged above the cylinder body and extending in the longitudinal direction, and an end plate joined to an end of the table body in the longitudinal direction so as to be substantially orthogonal to the table body.

Abstract: According to one embodiment, in general, an information processing apparatus includes one or more processors. The one or more processors receive from an onboard device of a probe vehicle an image showing a vehicle group of one or more vehicles stopping on the same lane, imaging time of the image, and a position of the probe vehicle at the imaging time. The one or more processors select vehicle groups according to the imaging time and an imaging position. The one or more processors identify the selected vehicle groups as a vehicle queue. The one or more processors calculate a stopping vehicle-queue evaluation value. The one or more processors calculate a parking vehicle-queue evaluation value. The one or more processors determine whether the identified vehicle queue is the stopping vehicle queue or the parking vehicle queue.

Abstract: According to one embodiment, generally, an information processing apparatus includes a vehicle detector, a stopped-vehicle evaluator, a parked-vehicle evaluator, and a determiner. The vehicle detector detects a vehicle from a captured image by an imaging device mounted in a probe vehicle. The stopped-vehicle evaluator calculates a stopped-vehicle evaluation value based on one or more stopped-vehicle conditions. The parked-vehicle evaluator calculates a parked-vehicle evaluation value based on one or more parked-vehicle conditions. The determiner determines whether the vehicle is stopped or parked based on both the evaluation values.

Abstract: A cylinder guide mechanism includes a floating bush, a holding part that holds the floating bush, and a linear guide. When a working fluid is supplied in a tube and a piston rod moves back and forth, the floating bush and a guide member of the linear guide move back and forth in the same direction. At this time, a slider of the linear guide is displaced relative to the guide member by retaining the same position. The slider is connected to the tube via an L-bracket.

The search unit obtains features of a first face image and a second face image of a predetermined person and searches for the predetermined person based on a similarity between the features of the first and the second face images when an inhibiting factor is not detected, and generates a third face image that is a composite image of the second face image and the inhibiting factor, obtains features of the first and the third face images, and searches for the predetermined person based on a similarity between the features of the first and the third face images when the inhibiting factor is detected. The display displays the search result of the predetermined person obtained by the search unit.
