Title: Game machine
Inventor: TANAKA KOHEI
IPC: A63F7/02
Filed: 2019-06-25
Abstract: To provide a game machine capable of prompting a player to secure a reserved random number.SOLUTION: During a time-shortening state, when a V-winning second small winning is produced and a limiter reaches the limit in a second jackpot to be almost reliably produced after the small winning, a Pachinko machine transfers the game state to a normal state. Then, when there is a second reservation (a residual reservation), the Pachinko machine executes second winning determination and, when a second jackpot is produced sequentially to the V-winning second small winning, transfers the game state again to the time-shortening state. The residual reservation cannot be secured during the second jackpot but secured during a symbol variable game and a second small winning in the time-shortening state. Accordingly, in order to accelerate timing of executing residual reservation notification for further reliably securing the residual reservation, when performance symbols are stationarily displayed in a symbol variable game in which the V-winning second small winning is produced as a result of the second winning determination and the limiter may reach the limit in the second jackpot produced after the small winning, the Pachinko machine lights a guide LED for guiding a rightward shooting (T2).SELECTED DRAWING: Figure 21

Title: Hybrid vehicle
Inventor: TAKASAKI ASUKA
IPC: B60L1/00
Filed: 2019-07-17
Abstract: To further stabilize the power balance of a fuel cell vehicle even if a request power and a state of a power storage device change when surplus power is consumed by a power consumption device in a hybrid vehicle.SOLUTION: A hybrid vehicle includes a power generation device, a drive motor, a power storage device, a power consumption device, and a control unit. When the drive motor operates in a power generation mode during braking, the control unit calculates a vehicle power balance value not including respective amounts of charge and discharge by the power storage device. In a case where the vehicle power balance value exceeds a first threshold, the control unit exerts consumption increase control for increasing consumption power of the power consumption device. In a case where, after the start of the consumption increase control, the vehicle power balance value decreases below a second threshold smaller than the first threshold, the control unit cancels the consumption increase control. The first threshold and the second threshold used when the allowable discharge power of the power storage device is smaller than a first reference power value, are larger than those used when the allowable charge power is equal to or larger than the first reference value.SELECTED DRAWING: Figure 2
