Abstract: A filament winding apparatus includes a rail extending in a first direction, a core material support device that supports a core material, and a winding device that winds a fiber bundle onto an outer peripheral surface of the core material, the winding device including: a guide unit having an opening through which the core material passes, and guiding the fiber bundle; and a main frame on which the guide unit is mounted; wherein the main frame is movable relative to the core material in the first direction, the main frame is movable in a second direction orthogonal to the first direction, and the main frame is rotatable around a first rotational axis extending in a third direction orthogonal to each of the first direction and the second direction.

Abstract: A filament winding device includes a fiber bundle retainer that temporarily retains fiber bundles. The fiber bundle retainer includes: a reel member including an outer peripheral portion having pins movable in the axial direction relative to the fiber bundles supplied through fiber bundle guides and rotatable about the axis of the liner, the reel member capable of winding the fiber bundles onto the outer peripheral portion; a first cutting unit configured to cut a part of each of the fiber bundles in the circumferential direction, the part being between a part of the fiber bundle wound on the outer peripheral portion and a part of the fiber bundle wound on the liner; and a second cutting unit different from the first cutting unit and configured to cut a part of each of the fiber bundles in the axial direction, the part being wound on the outer peripheral portion.

Abstract: A photographic material comprising a light sensitive photographic layer and a support having thereon in order a layer containing alumina sol including colloidal particles and an electrolyte and a layer containing a hydrophobic polymer.

Abstract: A method of undercoating a polyester film of a light sensitive photographic material is disclosed in which one side of the film is pretreated such that the contact angle with water is below 58.degree.. Additionally, a layer of an aqueous dispersion containing no organic solvent is applied to said side of said film, said dispersion containing a copolymer containing up to 60% by weight of glycidyl methacrylate and 25-60% by weight of ethyl acrylate.

Abstract: The present application is directed to a process for subbing a photographic hydrophobic film which involves subjecting at least one surface of the film to a hydrophylizing pretreatment step, coating the pretreated surface with an aqueous dispersion containing a polymer which has particular comonomers in a combined amount of more than 76%, then coating the coated surface with a liquid containing colloidal silica.

Abstract: This invention relates to a development inhibitor-releasing compound of the following general formula: ##SPC1##Wherein Z is an atomic grouping necessary to form a carbocyclic ring; Y is a group which, when the sulfur atom of the thioether linkage is released, forms together with said sulfur atom a compound having a development-inhibiting action; and X is a hydroxyl group or a substituted or non-substituted amino group.
