摘要： In an autonomous vehicle, position of a planar obstacle such as a wall or a fence having apertures is determined. A horizontal plane is scanned with a laser range tinder so as to acquire positional coordinates of a plurality of scanning points. An element vector is formed with each two scanning points so that one acquired former is used as a start point and the other acquired later as an end point of the vector. A plurality of continuous element vectors which satisfy predetermined conditions is selected among the element vectors, and a scanning segment vector is formed by composition of the selected element vectors. When a length of the scanning segment vector is equal to or longer than a predetermined length, it is possible to recognize that a planar obstacle exists along the scanning segment vector.

摘要： A fuel supply system has a cover, a pump unit, and metal pipes. The cover and the pump unit are connected through the use of the metal pipes so as to be moved relatively each other. A case cover, covering the pump unit, has supporting portions, each of which has a through hole. Each metal pipe is inserted through the through hole and thereby guided to be moved in its axial direction inside the supporting portion. The supporting portion has a plurality of grooves. Therefore, sliding resistance between the metal pipe and the supporting portion is reduced, that is, the pump unit can be smoothly moved relatively to the cover.

摘要： Emission gas recycling equipment includes a passage for recycling a part of an emission gas and a control valve for controlling an amount of the part of the emission gas. The control valve includes: a housing having a pipe portion; a butterfly valve accommodated in the pipe portion rotatable in a first direction and a second direction; a seal ring for sealing a clearance; and valve open/close operation means for stopping the butterfly valve at the valve full close position after the valve open/close operation means operates the butterfly valve to open and to close equal to or more than one cycle across the valve full close position at the time when the engine stops or after the engine stops.

摘要： An autonomous moving apparatus moving to a destination while detecting and avoiding an obstacle includes a radar device for scanning a horizontal plane in its travelling direction to thereby detect a position of an obstacle and an obstacle sensor for detecting an obstacle in a space different from the scanning plane of the radar device. The apparatus moves to the destination under such control as to avoid the obstacle based on detection information from the radar device and the obstacle sensor from a detection output provided by a specific-configuration detecting element for detecting a present specific configuration from scanning information by the radar device. By providing such a specific-configuration detecting element that detects a specific configuration based on the scan information by the radar device that can accurately know about position information, it is possible to guess an obstacle having an upper structure, thus providing efficient avoidance.

摘要： Intake passage in cylinder heads of an opposed six-cylinder engine. The cylinder heads are disposed on opposite sides of a crankcase including cylinder blocks.Three cylinders in each cylinder head are arranged in firing order. Intake valves and exhaust valves in each cylinder are disposed in the same arrangement at every cylinder so that the distance between the intake valves are equal to each other, and an intake passage in each cylinder head is so formed as to communicate intake valves with an opening. The opening is located at a position between two cylinders which are faster in firing order than the other cylinder.
