Abstract: A fluid-impermeable composite hose has a laminated layer composed of an inner winding layer formed by winding a laminated sheet spirally in a single layer, leaving a gap between every two adjoining turns, and an outer winding layer formed by winding a laminated sheet spirally in a single layer over the gap in the inner winding layer, leaving a gap between every two adjoining turns. The gap of the inner wind layer gives the hose flexibility and prevents the folding of the spirally wound sheet which might result in the failure of the hose to maintain its fluid impermeability.

Abstract: A fluid-impermeable composite hose has a laminated layer having a high impermeability to a refrigerant, etc. and held between two resin layers having a thickness which is small enough to enable the hose to remain flexible. The resin layers secure and protect the laminated layer and protect a metallic foil in the laminated layer from any bending, deforming or stretching force acting upon the hose.

Abstract: A 3-(substituted phenyl)pyrazole derivative or a salt thereof, the derivative being represented by the general formula ##STR1## wherein, X denotes halogen, R.sup.1 denotes lower alkyl, R.sup.2 denotes halogen and R.sup.3 denotes lower alkyl, lower alkenyl or benzyl group, a process for producing said pyrazole derivative, a herbicidal composition containing said pyrazole derivative as an active ingredient, and a method of controlling weeds by applying said composition.

Abstract: A thermosetting resin layer covers the outer peripheral surface of the nipple portion of a joint provided on one end of a connecting pipe. A hose having a reinforcing layer between a single- or double-layer inner tube and an outer tube is inserted over the nipple portion of the joint, and tightened by a caulked sleeve or clamp encircling the hose to form a joint structure. This joint structure provides a satisfactory seal for a long period of time, as its resin layer does not undergo any crystallization, but maintains elasticity.
