Abstract: A waste processing system includes a pyrolysis apparatus that pyrolyzes a combustible waste, a melt-and-mold apparatus that generates an ingot of resin and combustible gas from a synthetic-resin waste, and an oil extraction apparatus that generates combustible oil and combustible gas from the ingot of resin. The melt-and-mold apparatus has a melter that melts the synthetic-resin waste using heat produced by the pyrolysis apparatus, the oil extraction apparatus has a pyrolyzer that pyrolyzes the ingot of resin using the heat produced by the pyrolysis apparatus, and at least one of the combustible gas generated at the melt-and-mold apparatus and the combustible gas generated at the oil extraction apparatus is supplied to the pyrolysis apparatus.

Abstract: A grass cutter blade of the present invention inclines: a connection part for connection to a grass cutter; and a peripheral part extending from the connection part as a center and having an outer periphery that is inclined downwardly. The peripheral part is provided with a plurality of cutouts, each of which has an opening at the outer periphery. The peripheral part includes a region located further away from a rotation axis of the blade than an edge portion of each of the plurality of cutouts. There exist, in the edge portion, a first and a second end sections which extend to a deepest section, the first and second end sections pass through respective regions during rotation of the blade, and a distance exists between the respective regions in a direction orthogonal to the rotation axis with respect to a predetermined range in an up-and-down direction.

Abstract: A mixed fuel generation method comprises a step of mixing a fuel oil and at least one additional fluid other than the fuel oil, wherein one of the additional fluids is water, and a specific ratio that is a ratio of a volume of the water to a volume of the mixed fuel is 6% or less.

Abstract: Provided is a mixer including a ring-shaped swirl chamber; an inlet port which is connected to the swirl chamber in a direction tangential to the outer circumference of the swirl chamber to suck a fuel; a cylindrical vortex chamber coaxially and more inwardly formed with respect to the swirl chamber; a passage which connects the swirl chamber to the vortex chamber; and a taper port which is coaxially connected to the vortex chamber and is configured so that the inner diameter thereof is decreased from the vortex chamber-side end toward the opposite side end; and a supply port which is in communication with the taper port to suck a desired fluid.

Abstract: A mixer for a fuel feeding device comprises a swirl flow chamber having a doughnut-shaped space, an inflow hole connected to the swirl flow chamber from the outer peripheral side of the swirl flow chamber, a cylindrical section which is formed concentrically to the swirl flow chamber and which has a cylindrical space area, a tapered hole formed concentrically to the swirl flow chamber, diverged toward the swirl flow chamber, and connected to the swirl flow chamber and the cylindrical section, and an outflow hole which is formed concentrically to the swirl flow chamber and which communicates with the cylindrical section on the opposite side thereof to the side where the cylindrical section is connected to the tapered hole.

Abstract: An efficient internal combustion engine jointly using hydrogen obtained by dehydrogenation of a hydrogen supply mass. There is disclosed a hydrogen supply unit for internal combustion engine comprising hydrogen separating means, storage means for storage of separated hydrogen, means for storage of dehydrogenation products and means for addition supply of produced hydrogen to a fuel source.
