Title: Polarization state controlling device and program
Inventor: ANDO MICHINORI
IPC: G02B27/28
Filed: 2019-02-05
Abstract: To accurately control a phase delay amount of a retarder.SOLUTION: A light source light, having passed through a linear polarizer 12 for polarizing the light source light to linear polarization, is incident to a retarder 14. The retarder 14 changes a polarizing state of the incident light and emits the light, in accordance with an applied electric voltage. A mirror 16 causes a portion of the light source light having passed through the linear polarizer 12 to be reflected to an incident surface side in an emitting surface side of the retarder 14. The light that has been reflected by the mirror 16 and has passed through the linear polarizer 12 is received by a light amount monitor 18, and light amount data indicating the amount of the received light is output from the light amount monitor 18. A control part 20 controls the electric voltage applied to the retarder 14, on the basis of the amount of light obtained from the light amount monitor 18, so that light obtained by polarizing the incident light with a phase lag of λ/2 or 0 is emitted.SELECTED DRAWING: Figure 1

Title: Game machine
Inventor: IMOTO MASAHIKO
IPC: A63F7/02
Filed: 2019-02-13
Abstract: To provide a game machine capable of determining a degree of expectation toward winning in performance units under one variation performance while suppressing loss of interest in a game.SOLUTION: In a plurality of notice performances indicating degrees of expectation toward a jackpot under a variation performance, a rank of a degree of expectation indicated by each of the notice performances is separately determined. In this case, when a degree of expectation toward a jackpot of one rank is indicated in a notice performance under a variation performance, in a next notice performance (a subsequent notice performance), patterns which correspond to ranks having lower degrees of expectation toward a jackpot than that of the one rank are not selected in determination of the rank of the degree of expectation shown in the next notice performance. Thus, a decrease in degree of expectation toward a jackpot after a high degree of expectation toward a jackpot is shown can be prevented in the plurality of notice performances executed during one variation performance, thus suppressing the loss of player's interest.SELECTED DRAWING: Figure 36
