Abstract: A video slot machine starts spinning display of video reels upon detecting a spin operation, and performs a lottery to determine a special position in symbol stop positions in a reel display area. A character appears behind the video reel in such a manner that a displayed range of the character includes the symbol stop position determined to be the special position. When the video reels stop with a chance symbol stopped in front of the character, a replacement target is selected from the change symbol and other symbols in its periphery in accordance with a section of the character stopped by the chance symbol. Then, outcome of the reels is determined with the replacement target symbols replaced with a reward symbol, and payout is performed.

Abstract: A game device includes a processor implementing a character process that performs a character control process; a game process that performs a game parameter calculation process; and a display process that displays a game image based on results of the game process. The processor implements the character process that performs a process that controls a master character that is operated by a player, and a process that controls a plurality of subordinate characters that are subordinate to the master character. The processor implements the game process that performs a process regarding a game event that involves a first subordinate character and a second subordinate character based on a first relationship parameter between the first subordinate character and the second subordinate character, a second relationship parameter between the master character and the first subordinate character, and a third relationship parameter between the master character and the second subordinate character.

Abstract: It is possible to prevent an unauthorized read-out from both active tags and passive tags. Antenna emission is turned on and off by using a switch, or attenuated by using a resistor. A part of the antenna may be chipped. With these configurations, it is possible to lower the emission level of the antenna thus preventing an unauthorized read-out of important information from a remote reader.

Abstract: An optical sensor apparatus capable of accurate measurement without using a filter circuit, and therefore being further capable of pulse driving an LED and thus reducing power consumption, is provided. To achieve such an optical sensor apparatus, when an optical current sensor 10 is not sensing the current to be measured, an optical current sensor signal processing circuit 11 first supplies dc light of a specific intensity to the optical current sensor 10, and then adjusts the intensity of the light so that the intensity of light returned from the optical current sensor 10 to the signal processing circuit 11 is a specific predetermined value. When the optical current sensor 10 is sensing the current, the signal processing circuit 11 electrically processes the optical signal from the optical current sensor 10 to measure the current.
