Abstract: In a slot machine island wherein gaming medals can be distributed into juxtaposed slot machines and medal lending machines by a distributing conveyor belt extended in a horizontal direction; a medal distribution apparatus characterized by being so constructed that shafts each of which is rotated forwards and reversely by a reversible motor or a rotary solenoid are stretched across the conveyor belt inwards of respective release ports which are provided at predetermined intervals sideways of the conveyor belt, and that a guide valve is fixed to each of the shafts so as to fall, when its lower edge has approached the top surface of the conveyor belt in parallel therewith, into a shape in which the guide valve is located aslant the widthwise direction of the conveyor belt and is inclined relative to the corresponding release port.

Abstract: A token management system for a slot machine has a buffer tank communicating with a token counter and a collection conveyer, and also has a token polisher for continuously raising tokens in the buffer tank to a hopper while polishing the tokens. A main tank receives overflow tokens from the hopper, and supplies the tokens to the buffer tank when the hopper is empty.

Abstract: This invention provides a lead alloy foil comprising 0 to 4 wt % of tin, 0.5 to 7.0 wt % of antimony, and the balance being lead, wherein Sn/Sb ratio is 3 or less. It also provides a lead laminated tape for covering cables, comprising a lead alloy foil comprising 0 to 4 wt % of tin, 0.5 to 7.0 wt % of antimony, and the balance being lead, wherein Sn/Sb ratio is 3 or less, and an electrically conductive plastic film laminated at least one of the surfaces of the lead alloy foil and having a volume resistivity of 10.sup.6 .OMEGA.-cm or less.
