Abstract: An information processing apparatus (10) includes a time and space information acquisition unit (110) that acquires high-risk time and space information indicating a spatial region with an increased possibility of an accident occurring or of a crime being committed and a corresponding time slot, a possible surveillance target acquisition unit (120) that identifies a video to be analyzed from among a plurality of videos generated by capturing an image of each of a plurality of places, on the basis of the high-risk time and space information, and analyzes the identified video to acquire information of a possible surveillance target, and a target time and space identification unit (130) that identifies at least one of a spatial region where surveillance is to be conducted which is at least a portion of the spatial region or a time slot when surveillance is to be conducted, from among the spatial region and the time slot indicated by the high-risk time and space information, on the basis of the information of the

Abstract: A portable electric vacuum cleaner according to the present invention includes a body (23), and a suction nozzle (27) provided unitarily with the body (23) at a front lower portion of the body (23) and projecting forward from the body (23) as having a predetermined length. The suction nozzle (27) is, for example, a tubular member of a fixed shape composed of a resin and tapered toward a distal end thereof. The suction nozzle (27) has a nozzle suction port (271) provided at the distal end thereof. The portable electric vacuum cleaner is generally used with a floor brush (3) attached to the suction nozzle (27). When the floor brush (3) is detached from the body (2), the suction nozzle (27) appears. Thus, the portable electric vacuum cleaner is conveniently used. Further, the suction nozzle (27) is hardly missing.

Abstract: An apparatus for adjusting a timing of a needle and a looptaker of a sewing machine provided at a zigzag sewing machine having an upper shaft for driving a needle bar, a lower shaft for driving a looptaker, a machine frame, and a timing belt for connecting and synchronizing the shafts includes a cam member including a first cam surface and a second cam surface, a first arm member and a second arm member supported by the machine frame and a first pulley and a second pulley mounted to the first arm member and the second arm member respectively and always contacting the timing belt, the first pulley following the first cam surface and the second pulley following the second cam surface.
