Abstract: The present invention relates to a method for manufacturing processed cork chips, and a floor construction method using the same. The processed cork chips are manufactured by the method, including: crushing and drying cork chips; adding polyurea to the dried cork chips to prepare a mixture; heating the mixture to cure the same; and cooling the cured mixture. Further, the floor construction method includes: laying the processed cork chips on the surface of a floor formed of concrete, a water-permeable base layer or crushed stone with a solidified top surface; and flattening the processed cork chips and pressing the same by means of a roller at a fixed temperature.

Abstract: The invention provides a gas fuel supply kit for the existing vehicle (vehicle mounting a gasoline engine, or a diesel engine), in order to use a gas fuel such as hydrogen after wards. A post-installable type gas fuel supply kit to be installed in the existing vehicle such as a gasoline vehicle, comprising a gas fuel injector for supplying the gas fuel such as hydrogen to an intake path; an injector installing means for installing said gas fuel injector to a location which is a different location where a gasoline injector is installed; and a control unit for controlling at least an injection amount, and an injection timing of the gas fuel at the hydrogen fuel injector.

Abstract: To prevent a skid panel attached with wear resistance material of porcelain tiles or the like on its surface from warping in a longitudinal direction of laying the skid panel, a warp amount of a skid panel is predictively calculated from shrinkage strain, shrinkage force and upper and lower edge stresses of concrete, reverse camber is provided in the longitudinal direction of a mold of the skid panel with tensioning devices to nullify the final warp amount and concrete is fed to the mold to thereby fabricate the panel.

Abstract: Efficient paving operation requires that the levelling operation of asphalt be carried out accurately along a reference line which follows a given direction along a roadside. A simple and effective automatic control device for controlling the steering direction in conjunction with adjustments of the screed for an asphalt finisher (shortened to finisher) is presented. The control device automatically regulates the extension or retraction of the screeds on both sides of the finisher in reference to a visual display of the reference line following some objects along the roadside. The visual detection system of control is simple and economical and provides an accurate control over the direction of paving.

Abstract: A method of and an apparatus for heating a road surface, in which hot air controlled to a predetermined temperature is blown against the road surface so as to heat the road surface. The apparatus includes a hot air generator provided with a burner and a thermal control unit, and a duct formed with blowing pores for blowing the hot air against the road surface.

Abstract: A regenerative heating and melting device is disclosed for treating asphalt concrete rubble for the recovery of an asphalt coated aggregate suitable for reuse. The apparatus includes a vertical cylindrical casing, an inlet for hot gas and an outlet for exhaust gas, conveyor means for conveying the rubble to the top of the casing and means for recovering the regenerated paving material from the casing. The internal space of the cylindrical casing is divided into a plurality of tier sections by partition plates. Each of the plates has an opening means to communicate with the adjacent lower tier section. A rotary shaft is provided in the cylindrical casing, the axis of which coincides with the axis of the cylindrical casing and extending through the tier sections and partition plates.
