Abstract: Provided is a polishing pad comprising a polishing layer made of a polyurethane resin foam containing an isocyanate-terminated prepolymer, and a curing agent, wherein the ratio (NC80/NC40) of a weight proportion (NC80) of an amorphous phase content in the polishing layer measured at 80° C. by a pulsed NMR method to a weight proportion (NC40) of the amorphous phase content in the polishing layer measured at 40° C. by the pulsed NMR method is between 1.5 and 2.5.

Abstract: In a conveyance equipment having a conveyance path which serves to convey paper or the like, and an introduction path which merges with the conveyance path, for guiding to the conveyance path the paper or the like to be introduced into the conveyance system, the paper or the like is conveyed in a state in which it is erected within the conveyance path while being sandwiched in between conveyance members; a conveyance equipment for paper or the like is so constructed that means for separating and excluding foreign matter is formed at a bottom of the conveyance path. Also, a paper money collection system in a game island is constructed using the conveyance equipment.

Abstract: In a reserve tank structure for supplying, to a collecting gutter mounted slantedly in a lower part of a pachinko island and communicating with a lower tank above which a polishing and lifting device is located, pachinko balls which have flowed over the polishing and lifting device, a reserve tank is divided into a plurality of tank parts arranged on a plane. These parts each have an inclined bottom surface and each includes, under a lower portion of the entire reserve tank, an inclined lower gutter communicating with the bottom surfaces of the individual tank parts and also communicating with the collecting gutter.

Abstract: A game token dispenser is equipped with a token hopper for dispensing, to a token receiving port, a predetermined number of tokens supplied from a token reservoir. The token hopper is divided into a sequentially operating preliminary hopper and a dispensing hopper. The preliminary hopper has a sensor for detecting whether or not there are any tokens received from the reservoir, and a conveying mechanism for conveying the tokens forwardly. The dispensing hopper has a sensor for detecting whether or not there are any tokens received from the preliminary hopper. A discharging mechanism is provided for discharging the tokens one by one to the token receiving port. The dispenser preferably includes a display, on a front surface of a housing, for displaying whether or not it is possible to dispense the tokens and the number of the tokens dispensed.

Abstract: In a ball conveying gutter system, a gutter (21), (26) for carrying pachinko balls in order to supply them to the individual pachinko machines and for storing the pachinko balls is supported by successive gutter supports mounted respectively between successive pairs of confronting posts. Each gutter support has at opposite ends a pair of hooks, and the confronting posts of each pair have a pair of holes for detachably catching the opposite hooks respectively.

Abstract: A curtain panel assembly, for an island of game machines, which enables any person of the amusement arcade to look into the island easily and quickly to check the states of game mediums in a distribution gutter situated in the upper part of a support frame of the island or for the purpose of maintenance of the interior structure of the island. In the curtain panel assembly, a curtain panel is mounted on the upper part of the support frame outwardly thereof and is pivotally connected at its upper edge to the upper frame edge. The curtain panel has on its inside wall surface a mirror on which the image of the interior, e.g. the distribution gutter, of the island is reflected so as to be observed from outside when the curtain panel is moved angularly about the upper panel edge to open as the lower panel edge is pulled upwardly.

Abstract: A unit support frame structure, for a game machine island, comprises a pair of parallel horizontal shelf plates adapted to be attached to a pair of rows of game machines in the island, a plurality of vertical partition frame plates disposed under the shelf plates, two pair of parallel vertical posts mounted on opposite inner ends of the respective shelf plates, and a pair of gate-shape upper support frames connected at opposite lower portions of each support frame to upper end portions of the posts of the respective adjacent pair.
