Title: Game machine
Inventor: ISHIZUKA KEITA
IPC: A63F7/02
Filed: 2021-03-01
Abstract: To provide a game machine capable of increasing dynamic display time of one identification information while enhancing interest in a game without causing a player to get tired.SOLUTION: When false variation performed during one variation display is executed for five times (in the case of "five" false variation times), a "role" where it is determined that a special ready-to-win results and a jackpot results, and a "role" where it is determined that a ready-to-win does not result and complete losing results are at least granted. When the number of false variation times is five, it is configured that a degree of expectation toward a jackpot is the highest in the case where the ready-to-win is satisfied. Thus, a player can increase a degree of expectation toward satisfaction of a ready-to-win and a jackpot by repetition of false variation in a process reaching complete losing even if the complete losing results through five pseudo variations. Thus, interest in a game is enhanced without causing the player to get tired, and false continuation is allowed to occur frequently, thus increasing one average variation time.SELECTED DRAWING: Figure 8

IPC: H01M10/48
Filed: 2021-03-15
Abstract: To estimate the CCV of a battery in a shorter time interval than a voltage sampling cycle when the sampling cycle of a voltage sensor is longer than the sampling cycle of a current sensor.SOLUTION: A cell ECU 40 estimates a CCV at a mismatch timing where a voltage value is not acquired from a voltage sensor 22 although a current value is acquired from a current sensor 21.
