Publication number: 20140242653Abstract: A method for producing pyruvic acid from polysaccharide alginic acid that is contained in large amounts in brown algae using the ability to assimilate alginic acid possessed by a lactate-dehydrogenase-gene-deficient Sphingomonas sp. A1 strain (ldh strain) is provided. The method for producing pyruvic acid comprises culturing the lactate-dehydrogenase-gene-deficient Sphingomonas sp. A1 strain (ldh strain) in a medium containing alginic acid, and causing the strain to produce pyruvic acid from alginic acid and then to secrete pyruvic acid into the medium.Type: ApplicationFiled: February 25, 2014Publication date: August 28, 2014Applicants: MARUHA NICHIRO FOODS, INC., KYOTO UNIVERSITYInventors: KOUSAKU MURATA, SHIGEYUKI KAWAI, NOBUYUKI SATO

Patent number: 8417571Abstract: It is an object to increase advertising effectiveness by a synergetic effect between communication using a mobile phone or the like, and an electronic money system. The present embodiment is configured such that an advertisement is transmitted to a user's mobile phone via e-mail, and if the user purchases an article in values based on the advertisement, cashback is performed through the user's mobile phone in values. Thus, giving a feeling of value to the user makes it possible not only to increase advertising effectiveness but also to confirm the advertising effectiveness. If purchasing an article in values according to an advertising mail sent to a mobile phone 3, the user can receive the cashback from an electronic money server 2, thus allowing the user to obtain a feeling of value. Moreover, the electronic money server 2 can know whether or not the user has conducted purchasing activities in accordance with the advertising mail, allowing the advertising effectiveness to be measured and confirmed.Type: GrantFiled: September 5, 2006Date of Patent: April 9, 2013Assignee: Sony CorporationInventors: Norihiko Fujita, Shigeyuki Kawai, Makoto Yamada, Mikihisa Suzuki

Patent number: 7475044Abstract: The present invention offers an electronic money system and electronic money terminal that allow the user who uses an installment payment plan to decide the installment amount each time he/she pays it. Instead of debiting the amount data equivalent to consumption from an information card 50, the present invention accumulates the amount data equivalent to consumption as data on the transaction history of installment payments, receives part or all of the accumulated installment balance as an installment amount, subtracts the received installment amount from the installment balance to determine a new balance, and thereby allows the user to pay any part of the installment balance as an installment amount.Type: GrantFiled: April 21, 2000Date of Patent: January 6, 2009Assignee: Sony CorporationInventors: Shigeyuki Kawai, Koji Ito

Publication number: 20080301014Abstract: An electronic money system is provided which requires lower management and running cost, and features higher flexibility. An acquirer/brand holder managing an electronic money brand manages all keys used for authentication processing in the system, and issues the keys as necessary. The acquirer/brand holder distributes keys according to a tie-up agreement to IC card issuers, a POS center, an MMK center, and an affiliate merchant terminal unit. The POS center, the MMK center, and the affiliate merchant terminal unit are apparatuses for users to use the IC cards or for managing them. The acquirer/brand holder, however, does not distribute issued keys to cybershops which users can access by using a personal computer and a reader/writer. Instead, in this case the acquirer/brand holder saves the issued key itself, and carries out authentication processing with a predetermined IC card upon a request from the cybershop.Type: ApplicationFiled: July 24, 2008Publication date: December 4, 2008Applicant: SONY CORPORATIONInventors: Makoto Yamada, Nobumitsu Ukai, Junichi Sato, Shigeyuki Kawai, Tsutomu Okude, Koji Ito
