Abstract: A settlement system using electronic money for accessible objects includes a recording medium for electronic money information and a controller. The recording medium has an electronic money memory storing the electronic money information and an accumulative information memory storing accumulative information for granting a privilege. The accumulative information is accumulated according to spending the electronic money. The controller converts the accumulative information into the privilege on the basis of a set requirement.

Abstract: A deposit monitor system for game tokens includes a deposit and payout machine installed in an amusement place for depositing and paying out game tokens based on input of user authentication information, a web server configured to acquire and store the user authentication information and deposit information of the game tokens, an unique code for the amusement place, a web page of the amusement place, and a mobile terminal configured to fetch the unique code to display the web page and allow the user to input authentication information, wherein the mobile terminal acquires a URL by fetching the unique code, and when the web server compares the input user authentication information with the stored user authentication information, and if a user is authenticated based on the comparison, a web page corresponding to the URL with the deposit information of the game tokens of the user is displayed on the mobile terminal.

Abstract: An electronic money settlement system has a read/write unit configured to read electronic money information from the card, subtract a charge for an objective to be used by the user from the read electronic money information, and write the balance as new electronic money information into the card, the system also has a confirmation unit having a start button to provide a confirmation signal that confirms a start of use of the objective, and the confirmation signal makes the objective be ready and makes the read/write unit execute the subtraction.

Abstract: An electronic money settlement system for making settlement using an electronic money information storage medium 21 storing electronic money information, wherein the electronic money information storage medium 21 includes an electronic money storage area 27 storing the electronic money information, and a discount-rate storage 28 area storing a predetermined discount rate, and the discount rate is read from the discount-rate storage area 28, and according to the discount rate, settlement is made by the electronic money read from the electronic money storage area 27.

Abstract: The present invention resides, in a magnetic disk certifier for detecting one of a spike error and a positive modulation error on the basis of a read signal obtained by reading out by an MR head a test data written on a track of a magnetic disk as a first error of said magnetic disk and detecting one of a missing error and a negative modulation error as a second error, a method and apparatus for detecting a thermal asperity error of said MR head, by of detecting the first error and the second error in positions on said track, the positions having a recording length of a plurality of bits of the test data and judging a thermal asperity error when the first error and the second error are detected in one and the same position of the track.

Abstract: A bump disk including a standard protrusion having a predetermined height and a plurality of reference protrusions positioned either on substantially the same radial line as the standard protrusion or on a circumferential line having substantially the same radial distance as the standard protrusion under a predetermined positional relationship with respect to the standard protrusion, a method of calibrating the floating height of a protrusion detection head by making use of a standard circumferential speed determined with the bump disk and a glide tester using such calibration method.
