  • Patent number: 8821233
    Abstract: A game machine determines the reference timing included in a predetermined time range and the crossing direction position corresponding to the reference timing based on the sequence data (30). And, the game machine causes an instruction path (R) extending from one end side (UP) in depth direction (TD) toward the other end side (DP) while passing through each crossing direction position corresponding to each reference timing at a position on the time axis corresponding to each reference timing and the reference line (TL), to be displayed on the game screen, and decreases a distance between each position and the reference line (TL) with a decrease in a time difference between the reference timing and the current time.

  • Patent number: 8721856
    Abstract: A gas sensor control system for a gas sensor having a first, a second, and a third cell. The second cell produces a second cell electric current indicating the concentration of oxygen in gas in which the amount of oxygen has already been controlled by the first cell. The third cell produces a third cell electric current indicating the concentration of a preselected component of the gas in which the amount of oxygen has already been controlled by the first cell. A second cell circuit converts the second cell electric current into a voltage as a second cell current-measured value. A current adjuster produces a flow of an adjustment current as a function of the second cell current-measured value so that a third cell circuit converts the third cell electric current minus the adjustment current into a voltage as representing the concentration of the preselected component of the gas.

  • Patent number: 8595256
    Abstract: To eliminate restrictions on the order of writing in an access control list. A permission rule and a prohibition rule are stored in advance. A rule is read out from an access control list accepted, and a determination is made as to whether the readout rule is contained in the permission and prohibition rules stored in advance. When the readout rule is not contained and when the readout rule is a permission rule, the readout rule is stored in the temporary storage unit. When the readout rule is not contained and when the readout rule is a prohibition rule, a determination is made as to whether the prohibition rule conflicts with the permission rule stored in the temporary storage unit. When the prohibition rule does not conflict, the prohibition rule is stored in the temporary storage unit.
