Abstract: A cargo receiving facility includes a net and a transport mechanism. The net is suspended among supports. The net is configured to receive a cargo dropped from an unmanned aircraft in flight. The transport mechanism is configured to transport the cargo received by the net. The net has an elasticity corresponding to a mass of the cargo. The net has openings each having a size corresponding to a pressure of down-wash from the unmanned aircraft.

Abstract: Provided are urethane foam: which heightens toner charge amount (Q/M); by which toner is sufficiently absorbed in the surface layer of a toner-conveying roller to give a sufficient toner conveying ability; and by which a good image can be obtained with a low cost, and a toner-conveying roller using the same. Also provided are urethane foam in which substrate urethane foam is impregnated with one or more powders selected from the group consisting of silicone powder and silica powder, and a toner-conveying roller using the same. Preferred are urethane foam wherein said powder is bound with said substrate urethane foam via a binder, and a toner-conveying roller using the same.

Abstract: A sealing material is provided, which maintains excellent sealing property for a long period of time. The sealing material of the invention is characterized by being prepared by vulcanizing and foaming a mixture containing a rubber component containing a copolymer rubber of ethylene, an ?-olefin having 3 or more carbon atoms, and a non-conjugated diene, a vulcanizing agent, and a blowing agent, wherein the mixture contains a thermoplastic resin having a melting point of 80° C. or less.

Abstract: Provided are charge-controlled polyurethane foam by which the influence of electrification by friction between toner on the surface layer of a toner-conveying roller and a developing roller can be sufficiently prevented and by which a good image can be stably obtained with a low cost, and a toner-conveying roller using the same. The charge-controlled polyurethane foam is the one wherein the surface layer of the polyurethane foam is impregnated with a charge control agent which is on the negative side or on the positive side in the triboelectric series with respect to substrate polyurethane foam. The toner-conveying roller is the one which supports the charge-controlled polyurethane foam on the periphery of the axis of the roller.

Abstract: Provided is a sealing material having low hardness, low density, and excellent sealing properties. A sealing material, made by vulcanizing and foaming a blend containing: a thermoplastic resin; a foaming agent; a vulcanizing agent; and a rubber component containing a rubber copolymer of ethylene, a non-conjugate diene, and an ?-olefin with 3 or more carbon atoms; wherein the blend contains 2 to 4 mass parts of stearic acid and 5 to 7 mass parts of CaO in 100 mass parts of the rubber component, and the 50% compressive stress of the sealing material is 100 kPa or less.

Abstract: A sealing member is provided which has low permeability in the direction perpendicular to the compressing direction, has excellent water sealing capability, and can be elastically deformed at an increased rate. The sealing member is interposed between parts. The sealing member is composed of synthetic resin foam or rubber foam. The ratio of the permeability A in a compressing direction at non-compressed state to the permeability B in a direction perpendicular to the compressing direction at 50% compressed state in the compressing direction, that is A/B, is 1-40. The foam is punched to form needle holes from both sides in the compressing direction by needle punches 5, thereby manufacturing the sealing member.
