Abstract: An electrical connecting terminal has an elongated flat base portion. A female contact portion is formed on one end portion in the longitudinal direction of the base portion. A terminal portion is formed on the other end portion of the base portion. The contact portion has a pair of opposing elastic contact segments and a pair of opposing support segments. The segments are supported by the segments and extend toward the terminal portion. A pair of engaging segments, which restrict outward deformation of the contact segments, are formed on an intermediate portion of the base portion. A wrinkle portion is formed on an arbitrary portion of the base portion corresponding to the contact segments, thereby contracting the base portion in its longitudinal direction. Consequently, the distal ends of the contact segments are positioned between the engaging segments. One surface of the wrinkle portion is projected, and the other surface thereof is recessed.

Abstract: To form a multi-layer fiber web (34), especially of paper or cardboard, at least one of the two outer layers (34',34) is from a fiber material with at least one additive at the fiber surfaces. For a multi-layer paper/cardboard web, the additive is deposited on the surfaces of hollow fibers and, in addition, within the hollow fibers and at their walls. The additive includes a filling material, and the outer layers of the web have a higher filling material content than a center layer. Calcium carbonate is used as the additive or filling material at the wet fibers, or is used as a precipitate. To apply the calcium carbonate to wet fibers, a medium with calcium oxide and/or calcium hydroxide is used so that at least a portion associates with the water at the fibers. The treated fibers are exposed to carbon dioxide to give a chemical reaction with the calcium carbonate at the fiber surfaces. The calcium oxide and/or calcium hydroxide is used at a rate of 0.1-50.0 wt.% of the fiber dry weight. The fibers are treated with carbon dioxide in a closed vessel, as a gas under pressure, during a mixing phase where a high shear effect is applied to the fibers using an energy of at least 10-50 W/hr/kg based on the dry weight. The fiber material is derived in a pulper from cellulose or used paper materials, or it is a never-dried pulp. An Independent claim is included for a papermaking/cardboard production machine, to produce a multi-layer web, with stock inlet channels (36,40) charged with fiber materials where an additive is deposited on the fiber surfaces at least partially. Preferred Features: The multi-layer stock inlet assembly (28) is structured to form a web with two outer layers or a sandwich with an intermediate layer, where the pulp for the outer layers has fibers with an additive on their surfaces.
