摘要:
A contents providing system provides contents and associated data corresponding to the contents to a plurality of information processing devices. The contents providing system is equipped with a transfer control section that executes a control as to whether a change made to first associated data stored in a first information processing device corresponding to a set of contents is to be transferred from the first information processing device to a second information processing device that stores second associated data corresponding to the set of contents, and the transfer control section executes the control when a specified event occurs.
摘要:
An object of the present invention is to provide a spiral membrane element that can form a uniform fiber reinforcement layer on an outer circumferential surface by a simple process without a great change in the materials, as well as a process for producing the same. The spiral membrane element of the present invention is a spiral membrane element which is provided with a cylindrical roll R in which a separation membrane, a feed-side flow passageway member, and a permeate-side flow passageway member 3 are spirally wound in a laminate state around a perforated center tube 5 and in which a sealing part for preventing mixing of feed-side fluid and permeate-side fluid is disposed, wherein at least one sheet of the permeate-side flow passageway member 3 has a fiber cloth 23a extended or connected to the outer circumferential side, and the fiber cloth 23a is wound around an outer circumference of said cylindrical roll R, impregnated with a resin and hardened to thereby form a fiber reinforcement layer.
摘要:
A contents providing system provides a content and attached information of the content stored in a contents controlling apparatus to a terminal apparatus. The contents providing system includes a determination section that determines whether or not a specific content among a plurality of contents stored in the contents controlling apparatus is stored in the terminal apparatus, and a transfer section that transfers the specific content and attached information of the specific content to the terminal apparatus when the determination section determines that the specific content is not stored in the terminal apparatus, and transfers only the attached information of the specific content instead of both the specific content and the attached information of the specific content when the determination section determines that the specific content is stored in the terminal apparatus.
