Title: Lighting device
Inventor: MIYAHARA DAIKI
IPC: F21Y103/00
Filed: 2003-02-17
Abstract: <P>PROBLEM TO BE SOLVED: To provide a lighting device of constant-brightness illumination, high directivity in light beam, and high utilization of the light beam.  <P>SOLUTION: The lighting device comprises a light source 201, a lightguide plate 202, and a reflecting plate 203. The lightguide plate 202 is provided with multiple grooves 207 on its rear surface 202a which directs the light from an incident surface toward an exit surface. The multiple grooves 207 at the part closer to the incident surface and the part closer to the end on the side opposite to the incident surface have a narrow pitch P2 compared to a central part. The light quantity advancing toward the exit surface becomes larger at the lightguide plate at the part closer to the incident surface and the part closer to the tip end, thus brightness distribution is constant over the entire light emission surface.  <P>COPYRIGHT: (C)2004,JPO

Title: Game machine
Inventor: SATO SHOJI
IPC: A63F7/02
Filed: 2003-02-17
Abstract: <P>PROBLEM TO BE SOLVED: To suppress the occurrence of the situation that winning is hardly attained in a high probability state.  <P>SOLUTION: When a special pattern is variably displayed for 60 times in the high probability state (big winning probability of 1/60) (S330:YES, equivalent to a prescribed first condition), the big winning probability is increased to 1/36 (S340). Thus, the occurrence of the situation that the winning is hardly attained though the high probability state is suppressed. Also, while the opening time of a wing piece is shortened to 0.3 sec (S345), since entries before it is shortened are held, the special pattern is varied for that and the occurrence of the situation that the special pattern is not varied since it is hard to enter a first kind start port is prevented. In the case that a holding number still becomes zero (S370:YES), since the opening time of the wing piece is extended again (S305), a player is prevented from become too disadvantageous.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
