Abstract: There is provided a distribution apparatus in which transmission losses at the connections between ends of transmission lines and input and output terminals of a mother board are reduced. These ends of the transmission lines are positioned on resin support pieces. A resin support piece (19) is provided at a dead end of each groove (6a) formed in a housing (1). An end portion of a metal rod (6b) is placed on the support piece (19). The end portion of the rod (6b) has a threaded hole (20) formed therethrough. The mother board (11) is provided with two first lands (22,23) each surrounding a screw hole (21). A screw (22a) is tightened in each threaded hole (20), which is part of a main line connection terminal (5b), thereby bringing the head of the screw (22a) into firm contact with the first land (22) and establishing an electrical connection between the first land (22) and the conductive rod (6b).

Abstract: A dot printing wire is provided at its tip with a wear-resistant contact made of an alloy selected from the group consisting of alloys composed of two or more platinum group metals, alloys of platinum group metals and transition metals and alloys of platinum group metals, transition metals and boron.
