Abstract: A game system correlates games played on cellular phones with games played on arcade game machines.

Abstract: To detect a variation of capacitance in a path of a piping and enable to decide a fluid state of a fluid substance flowing through the path in the piping, a capacitance sensor (15) includes a measuring electrode (33) and a grounding electrode (35) made of a conductive metallic film and wound around a path in the piping (1), with an insulator (17) in between. A shield member (23) covers the measuring electrode and grounding electrode, with an insulator in between. The grounding electrode is narrower than the measuring electrode, and the measuring electrode and the grounding electrode are alternately disposed and are wound to be spiral along a flow direction.

Abstract: A game system using tokens allows a user to play a game on a mobile communication terminal at a location remote from a game hall. The game system includes a game hall (1) to lend tokens to a player so that the player may play game machines (3) installed in the game hall with the tokens, keep tokens deposited by the player after the play, and return the kept tokens to the player so that the player may play the game machines with the tokens, a management unit (7) provided for the game hall, connectable to the Internet and having a database (9) to store and update data on the kept tokens, a mobile communication terminal (13) connectable to the Internet to receive game content and allow the player to play a game on the mobile communication terminal, and a game content provider (11) to provide the game content to the Internet.

Abstract: A money changer management system enables an easy inventory of a money changer (1) and prevents accidents. The system includes the money changer and a management unit (3). The money changer has a cabinet (5) having a lockable door (7), a lockable change unit (25) installed in the cabinet, to hold money and dispense money of equal value in exchange for money deposited into the money changer, the held, dispensed, and deposited money being at least one of paper money and hard money, and a circulator-counter (31, 33, 35) to count the money in the change unit while once circulating the money in the change unit. The management unit manages the money in the money changer according to information about the amount of the money in the money changer and information from the circulator-counter.

Abstract: An apparatus surely and easily controls articles kept in, for example, a safe.

Abstract: A content delivering system allows easy acquisition of content upon personal authentication.

Abstract: A measuring apparatus correctly measures the purity, mixing ratio, and the like of an insulative (nonconductive) fluid such as ultrapure water flowing through a passage.

Abstract: The program for personal authentication in a mobile phone enables the mobile phone user to buy a commodity without cash and a card, and without entering a password.

Abstract: A fermentation controller correctly controls fermentation and produces a required material by fermentation.
