Title: Non-powered waterproof door device
Inventor: ANAI TOMOOKI
IPC: E04H9/14
Filed: 2020-02-04
Abstract: To provide a waterproof door that can be operated without the need for manpower when a disaster occurs.SOLUTION: A non-powered watertight door system 30 includes: a set of waterproof doors 32, a waterproof door support device 34 that supports the waterproof doors 32 to rotate under their own weight from the face-to-face state to a direction away from each other, and a buoyancy force generator 38 that is activated by buoyancy. When water flows into a water reservoir 42 due to heavy rain or high tides with the result that buoyancy is generated in the buoyancy force generator 38, the waterproof doors 32 rise in conjunction with the rising of the buoyancy force generator 38. Under normal circumstances, the lower end of the waterproof doors 32 are inside the water reservoir 42 and theirs free rotations are restricted, but the restrictions are released when water rises to the outside of the water reservoir 42, their rotations by their own weights start to cause an above-ground opening 100 to be closed, thereby preventing water from entering an underground structure.SELECTED DRAWING: Figure 4

Filed: 2020-03-10
Abstract: To provide a game machine capable of normally performing main control of a game while achieving various kinds of control by determining contents relating to a lottery or the like.SOLUTION: In a Pachinko machine 10, apart from a jackpot lottery performed at the start of executing a variation performance, each counter value acquired and reserved upon trigger winning is read ahead, and read-ahead processing for determining a result of the jackpot lottery is executed. While the read-ahead processing is executed in main processing, the jackpot lottery or the like is executed in timer interruption processing to be executed more preferentially than the main processing. Thus, since the timer interruption processing is executed preferentially even during the execution of the read-ahead processing in the main processing, the jackpot lottery can be performed without any delay at the start time of the execution of the variation performance. On the other hand, even if the timer interruption processing is executed during the read-ahead processing, it is successively performed after completion of the timer interruption processing and thus the read-ahead processing can be completed reliably.SELECTED DRAWING: Figure 24
