Abstract: A bottle washing nozzle which is capable of washing bottles having openings of different diameters and which is capable of washing bottles having projections, indentations, and a square cross-section, or the like, with good efficiency. The nozzle includes a central jet tube a first jet orifice which jets in a vertical direction, second jet orifices which jet in an oblique upward direction in the base section of the central jet tube, and an discharge controlling means in the outer circumferential section of the nozzle main body, below the second jet orifices.

Abstract: A treated pigment and a dispersion composition thereof having preferable dispersion stability and fluidity in a dispersion medium even the pigment has no functional group reactive with a carbodiimide group on the surface thereof, and further to provide a resist composition exerting very excellent developing characteristics when forming color filters, black matrices and the like patterns. Furthermore, the invention also provides a compound for pigment treatment suited for the treatment of such pigment. A treated pigment which is producible by the treatment with a carbodiimide-based compound having at least one side chain selected from the group consisting of polyester side chains, polyether side chains and polyacrylic side chains and at least one basic nitrogen-containing group within the molecule.

Abstract: The present invention provides a treated pigment produced by treating at least one pigment selected from the group consisting of organic pigments and carbon black each having a functional group reactive with a carbodiimide group with a carbodiimide compound having one or more carbodiimide groups, said carbodiimide compound having, within the molecule thereof, at least one side chain selected from the group consisting of polyester side chains, polyether side chains and polyacrylic side chains, with a carbodiimide equivalent of 100 to 50,000.

Abstract: Disclosed herein is an improved method for forming a double wall container by laminating a thermoplastic resin sheet for a container main body and a breathable thermoplastic resin sheet or film for an inner body with a low-melting adhesive, heating the laminate sheet at a forming temperature, and forming the heated laminate sheet by using a male and female molds arranged with a certain space, characterized in that the container main body and the breathable inner body are separated with a prescribed distance from each other by vacuum suction through the female mold or by air pressure through the male mold. On account of the double wall structure, the container prevents the content from becoming sticky and deteriorated and keeps the content fresh.

Abstract: A method for producing cross-linked polyethylene resin foams which comprises mixing a polyolefin resin, a blowing agent and, optionally, a surface active agent containing hydroxyl groups or an acid amide compound under pressure, said polyolefin resin containing a cross-linkable ethylene polymer having on the side chains thereof silyl groups which effect cross-linking upon contact with water; extruding the mixture into a low pressure zone where the extrudate is allowed to expand; and bringing the expanded extrudate into contact with a silanol condensing catalyst so that the expanded extrudate is cross-linked on contact with water.

Abstract: A blow molding method and machine and more particularly a method and machine for extruding a multi-layer parison for blow molding, wherein at least two layers of molding plastics, each plastic compensating the poor or undesirable physical and chemical properties of the other plastic and/or each having a different color are forced to flow through different passages having an annular cross sectional configuration, and are joined at the junction of a short passage to be extruded into a multi-layer parison.
