Abstract: PURPOSE:To generate a desired specular surface without requiring polishing and rinsing by laying an undercoat layer of polyurethane resin, a metal evaporation film, and an overcoat layer one over another on the surface of a light metal casting, and masking the wheel body so that a specular surface part is formed. CONSTITUTION:A wheel body 1 is made by forming an undercoat layer 3, a metal evaporation film 4, and an overcoat layer 5 one over another on the surface of a light metal casting 2. An example of light metal casting 2 is of aluminum alloy which particularly excels in presenting good design. The undercoat layer 3 is particularly formed out of polyurethane resin, and its thickness ranges 5-100mum so that the micro-unevenness 2a on surface of the casting 2 is filled up. The metal evaporation film 4 is favorably prepared through evaporation of aluminum which is chiefly excellent in the reflectance. Example of overcoat layer 5 is of fluoric resin, which is favorable in not impairing the luster of the metal.

Title: Game machine
Inventor: WATANABE KANEHISA
IPC: A63F7/02
Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To obtain an interesting display mode for a game player by setting time until a pattern of a first pattern display part is stopped and displayed after pattern change started time shorter than a nonesuch case when a pattern stopped at and displayed on the first pattern display part is a preset pattern. SOLUTION: When a prize is won in an ordinary motor-driven generator (a pattern starting port) 7, first and second pattern display parts L1 and L2 start to change. Whether it is a big hit, a miss reach or a miss is judged, and when there is the possibility of becoming a big hit (a special game condition), after a patter change is started, for example, after 5 seconds, either of special patterns (an odd number) is stopped at and displayed on the first pattern display part L1. On the other hand, when it is a miss, an even number pattern is stopped and displayed after the pattern change is started, for example, after 5.5 seconds. Therefore, when there is the possibility of a big hit, since time until a pattern of the second pattern display part is stopped becomes long, an interest can be given to a game player.
