Abstract: A tubular elastic linkage device for axle beam for elastically linking a truck frame and an axle beam including: an inner axial member; two outer segments opposed in axis-perpendicular direction peripherally outside the inner axial member for attachment to a housing part on an axle-beam side; and a main rubber elastic body elastically connecting them. A pocket part opens in an outer peripheral face of the main rubber elastic body onto outside via a window penetrating one outer segment. A stopper supported by the inner axial member is disposed in the pocket part to face the housing part distantly via the window. Contact of the stopper with the housing part constitutes a displacement limitation mechanism between the inner axial member and the outer segments. The other outer segment has an aperture having the main rubber elastic body exposed outside via it.

Abstract: Each of an assembly for air spring, an air spring, and a carriage for vehicle includes: a first supporting member; a second supporting member arranged to be spaced away from the first supporting member in a main load direction; and an adjusting member connected to the first supporting member and the second supporting member in a plane crossing the main load direction, the adjusting member having anisotropy in elastic property in the plane crossing the main load direction.

Abstract: A first bearing casing accommodates a first spherical bearing while restricting a displacement of the first spherical bearing in an axial direction, and a second bearing casing accommodates a second spherical bearing while allowing a displacement of the second spherical bearing in the axial direction. The second bearing casing includes a protruding portion interposed between each of second oil sealing members and the second spherical bearing so as to be spaced apart from the second spherical bearing in the axial direction.

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: A hydrophobic plastic support which has a layer thereon comprising a copolymer, said copolymer consisting essentially of an acrylic monomer selected from alkyl esters of acrylic acid and alkyl esters of methacrylic acid, and an ethylenically unsaturated monomer having a group of the formula--COXROHwherein X stands for an oxygen atom or ##STR1## in which R' stands for a hydrogen atom, a substituted or unsubstituted alkyl group or a hydroxy group, and R stands for a substituted or unsubstituted alkylene group.

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.
