Publication number: 20060059038Abstract: The present invention is relative to a system enabling a through operation between a mileage system and an electronic money system. The mileage system is such a system in which mile points as distance points corresponding to the flight distance of an aircraft are accumulated and exchanged for boarding tickets and other services. An IC card (230) having stored a wallet number in it is used. The wallet number and a mileage number are managed in a correlated fashion. Responsively to a request from a user, reference is made to an electronic money value ledger (222), matched to the wallet number, while reference is also made to a mile point ledger (122), matched to the mileage number. A preset number of the mile points are changed over to an electronic money value and, depending on changed-over results, the electronic money value ledger is subjected to integration processing, while the mile point ledger is subjected to deduction processing.Type: ApplicationFiled: March 1, 2004Publication date: March 16, 2006Applicant: Sony CorporationInventors: Akihiro Iuchi, Tadashi Saito, Akio Uchida, Soichi Umase, Koji Ito, Tomokuni Shibuya, Tsutomu Okude

Patent number: 4317155Abstract: A novel gap type surge absorber. The surge absorber comprises a plurality of conductive ceramic thin films formed on the surface of a molded insulating body and separated from each other by an extremely narrow gap, electrodes composed of a metallic material fixed to both ends of the plural conductive ceramic thin films and an inert gas sealed between the electrodes. The surge absorber is based on a two-stage discharge mechanism consisting of a discharge due to electrons emitted between the conductive ceramic thin films when a surge voltage is applied to the electrodes and a following creeping discharge generated between the electrodes. The surge absorber has a prolonged life and a good annealing characteristic as well as a very small discharge lag and a small electrostatic capacity and is excellent in cutting off a follow current.Type: GrantFiled: August 20, 1979Date of Patent: February 23, 1982Inventors: Mikio Harada, Kan-ichi Tachibana, Akio Uchida, Takashi Saitoh

Patent number: 3961225Abstract: A novel gap type surge absorber is disclosed. The surge absorber comprises a plurality of carbon thin films isolated from each others at short distances attached to the surface of an insulating body and one material selected from the group consisting of a metal, an alloy and a conductive adhesive as an electrode fixed to each of the plural carbon thin films. The surge absorber is an element based on a new mechanism that when a surge voltage reaches a prescribed value, a discharge is generated owing to emission of electrons between the carbon thin films and thereby a creeping discharge is initiated between the electrodes. The surge absorber has a small electrostatic capacity as well as a small discharge lag and is capable of cutting off a follow current.Type: GrantFiled: February 10, 1975Date of Patent: June 1, 1976Assignee: Mitsubishi Mining & Cement Company, Ltd.Inventors: Kan-ichi Tachibana, Michihiro Nishioka, Akio Uchida, Mikiya Ono
