Abstract: A polygon retrieving method includes converting a random polygonal area indicating a shape of each lane of a road within a predetermined unit area on a map into polygonal information indicated using coordinates of vertexes of the polygonal area and storing the polygonal information in the storage in association with a unit area, specifying temporospatial information including positional information corresponding to coordinates within the predetermined unit area on the map, and extracting all temporospatial information including positional information corresponding to coordinates inside a polygonal area indicated by the polygonal information associated with the unit area among the specified temporospatial information, by processing circuitry.

Abstract: An engine-powered work tool includes an air-cooled engine having a crank shaft, an engine output controller, a wind governor including a governor plate, and a throttle-opening assisting mechanism. The engine output controller includes a throttle valve shaft angularly rotatable about its axis for controlling a rotation speed of the crank shaft based on the angular rotation of the throttle valve shaft. The governor plate is connected to the throttle valve shaft for receiving cooling air generated by a cooling fan connected to the crank shaft. The wind governor controls angular rotation of the throttle valve shaft based on an amount of the received cooling air. The throttle-operation assisting mechanism causes the throttle valve shaft to angularly rotate in a direction to increase the output of the engine within a prescribed rotation speed range, the operation by the throttle-operation assisting mechanism being predominant over the control by the wind governor.

Abstract: A 2-cycle engine has: a piston reciprocably housed in a cylinder bore; an intake opening, an exhaust opening, and a scavenge opening provided in an inner peripheral wall of the cylinder bore and opened/closed by the piston; and a scavenge passage connecting the scavenge opening and a crank chamber. A valve that opens/closes the scavenge passage is provided on the scavenge passage.

Abstract: A reciprocating tool (1) includes a housing (20, 30), a driving source (21), a reciprocation conversion unit (34, 36), —and a vibration reduction mechanism (30). The driving source is accommodated in the” housing. The reciprocation conversion unit (34, 36) is supported by the housing and is configured to convert a driving force of the driving source into a reciprocating motion for providing a tool bit (16) movably supported to the housing with a reciprocating motion. The vibration reduction mechanism (70) includes a shaft (72), a weight (71), a support member (73), and a urging portion (74). The shaft i(72)s supported by the housing and extending in a direction perpendicular to directions of the reciprocating motion of the tool bit (41) t and has an axis. The weight (71) is located away from the shaft (72) and is swingable in a swinging direction. The support member (73) swingably supports the weight (71) about the axis of the shaft (72).

Abstract: A power tool with a dust collection function has a motor, a dust collection fan, and a cover member. The dust collection fan is driven by the motor for collecting a dust. The cover member covers the dust collection fan. The cover member provides an air passage surrounding the dust collection fan in a circumferential direction of the dust collection fan. The cover member is configured and arranged to provide a lower pressure section and another section in the air passage when the dust collection fan rotates. The lower pressure section provides a lower static pressure than the another section. Accordingly, the power tool ensures highly efficiency for collecting a dust particle.
