The drive pulley has a drive shaft direction length less than a plurality of previously set belt widths of the endless belt and has the driving shaft direction length being set to a same length regardless of the plurality of previously set belt widths of the endless belt. Axial lengths of the first pulley and the second pulley are set to the same length as the axial lengths of the head pulley and the tail pulley. The support frame is rotatably attached to the first pulley and the second pulley. The drive motor hung from a lower surface of the support frame in order for the drive pulley to be positioned at an approximately center portion in a width direction of the endless belt.

Abstract: A belt junction belt conveyor in which a thick periphery edge of a belt is elastically held after the belt is rewound by upper and lower inclined pulleys so that the meandering tendency of the belt occurring from being rewound by the upper and lower inclined pulleys is effectively prevented.

Abstract: A road-ice detecting sensor includes: a temperature sensing member of T shape made of a highly heat conductive metal, having a temperature sensor to be grounded onto a road and a fin part erected from this temperature sensor; an optical fiber having an FBG bonded onto the fin part of the temperature sensing member; and a case having a heat insulating member surrounding the fin part of the temperature sensing member and the optical fiber. A plurality of number of the read-ice detecting sensors are installed on a road, connected to one another via an optical cable. Pulsed light is launched into one of the ends of the optical cable, and beams of reflected light from the respective road-ice detecting sensors are received to measure the road temperature.

Abstract: The object is to provide a construction method of an information-communicable underground pipe whereby communication cables can be readily laid in an underground pipeline having a main pipe and branch pipes branched therefrom thereby allowing the underground pipeline to be used as an information-communicable underground pipe, and to provide a construction structure and a construction member therefor.

Abstract: A method and a system for cleaning the glass surface of an object, such as a surface light, a run way guide light, or a reflector, installed on various pavements or roads, by propelling a cleaning agent from a blast nozzle to the glass surface. The blast nozzle is installed on the front end of an arm of a working robot mounted on a truck. A truck mounted with a cleaning agent blaster and a working robot (21) provided with a blast nozzle (23) and a CCD camera (24) at the forward end of a manipulator is stopped at a specified position in the vicinity of an object to be cleaned, i.e. surface light or a reflection mirror (30). Based on an image of the object taken by the CCD camera (24), dimensions are recognized from distance information through processing by a vehicle-mounted computer, the image shape of the object is collated with a stored shape and recognized, and then positional information of the recognized object is searched.
