Abstract: A highly-convenient content duplication management system for allowing users to duplicate a content as long as the duplication is in compliance with a given usage right. In the system, a request destination device stores a content and a permitted number of duplications of the content. In response to a duplication request, the request destination device judges whether or not the request source device is an in-group device that belongs to the same group as the request destination device. When judging that the request source device is an in-group device, the request destination device transmits the content together with a permitted number that is equal to or smaller than the currently stored permitted number. The request destination device then updates the currently stored permitted number by subtracting the permitted number transmitted.

Abstract: In order to solve a problem in a conventional device in which an operation lever is stepped on by a foot to supply oil to an elevating/lowering cylinder, in that since oil supply to the elevating/lowering cylinder is stopped every time the operation lever is stepped on, a seat part stops every time oil supply to the hydraulic cylinder is stopped, and in that such a device gives the person who receives technician's work shock and an uncomfortable feeling, a chair elevating/lowering hydraulic device is composed of a foot pump 3 which absorbs oil by an ascent of an operation lever 1, which discharges oil stored by a stepping-on of the operation lever, and which discharges stored oil by a stepping-on of the operation lever to a lowest position, a check valve 5 which is opened by the oil pressure of the oil discharged from the foot pump, which is opened when the foot pump is lowered to the lowest position, and which allows the oil from the non-return side to pass to allow it to return to an oil tank through the fo

Abstract: A method for simply and efficiently separating substances by utilizing a specific flow behavior in a non-turbulent flow, i.e. a laminar flow, in a micro-channel is disclosed. A mixed solution containing at least two kinds of solute molecules which are different from each other in molecular weight and/or molecular sharp, or at least two kinds of solutions containing their respective solute molecules are flowed into a micro-channel to form a non-turbulent flow. A physical action is given to each molecule by changing the state of flow, thereby causing different behaviors among the different solute molecules. By utilizing this behavior difference, molecules of a specific kind are gathered in a specific region in the channel for separation.

Abstract: When print data PD generated by applications 100 is supplied to a graphics library 110 in an order of describing objects, the graphics library 110 makes correspond print data PD to objects so as to store print data PD in a metafile 120. After print data for one page has been stored in the metafile 120, the metafile 120 is retrieved. Thus, print data PD is reconstructed for each band. A printer driver 130 converts reconstructed print data PD into the PDL data PD? so as to transfer the PDL data PD? to an output apparatus 2. A decomposer 140 does not generate intermediate format data and directly develops the PDL data PD? in a band buffer 22. An output device 24 reads raster data RD from the band buffer 22 so as to print an image on a paper sheet.

Abstract: A distribution server 103 distributes a content via a network, and a KIOSK terminal 105 receives the content via the network and records the content in an SD memory card 100. A customer device 111 receives a content via the SD memory card 100, checks out the content and records a copy on a recording medium. SD-Audio players 122 to 124 receive a copy of the content and play back the copy. Here, the KIOSK terminal 105 records a Usage Rule that certifies the right to control recording of content on the SD memory card 100. Move Control Information showing the number of times that moving of rights is permitted is set in the Usage Rule.

Abstract: The present invention relates to a method of manufacturing a micro reactor device that includes a tubular reactor (1) as a flow path, for allowing reaction species to react in the reactor (1). The micro reactor device is manufactured by forming a particle layer (2) on an inner wall of the reactor (1).

In this way, it is possible to provide a method of manufacturing a micro reactor device having an inner wall modified so that the reaction species can react more efficiently, and to provide the micro reactor device.

Abstract: The invention discloses a novel method for the preparation of a 2-keto carboxylic acid from carbon dioxide by an enzymatic addition reaction with an aldehyde compound. Carbon dioxide, which can be in the form of carbonate ions, is reacted with an aldehyde compound such as acetaldehyde and propionaldehyde under mild reaction conditions in the presence of a decarboxylase to give a 2-keto carboxylic acid such as pyruvic and a 2-ketobutyric acid by a reverse reaction to the enzymatic decarboxylation reaction. The scope of the invention involves contribution to a solution of the environmental problem of global warming due to carbon dioxide as a greenhouse effect gas in the aerospace.

Abstract: A method of chemically reacting two or more reactants which react one another, which comprises fixing molecules of the reactants to fluids and supplying them to a microchannel to efficiently conduct the chemical reaction based on the molecular structure or molecular orientation imparted to the microchannel or on the function of changing the distributed state of molecules in a solution.

Abstract: A novel method for analyzing a specimen molecule with high accuracy through a simple operation by forming a laminar flow of a specimen molecule containing solution and a complex forming molecule containing solution in a microchannel and measuring the variation of the degree of diffusion of complexes each composed of a specimen molecule and a complex forming molecule in the laminar flow. The complex forming molecule is fluorescent, and the variation of the degree of diffusion of the formed complexes is measured from the distribution of intensity of fluorescence. The degree of diffusion of the formed complexes can be quantitatively determined by comparing it with a calibration curve preliminarily defined.

Abstract: A content-duplication management system formed from a playback apparatus that requests and plays contents, and a content-duplication management apparatus that manages duplication and deletion of contents. The playback apparatus notifies group information of the playback apparatus to the content-duplication management apparatus, acquires information from the content-duplication management apparatus showing whether requests are permitted, and duplicates/deletes contents.

Abstract: A group formation/management system that rigidly sets the range of a group, and allows contents to be used freely among member devices in the group, the system including one or more registered member devices operable to hold common secret information unique to the group, a new member device operable to transmit a request for registration in the group and to receive and hold common secret information, and a group management device operable to receive the registration request from the new member device and, when the number of registered member devices is less than the maximum number of registerable member devices, to output the common secret information to the new member device. Furthermore, because member devices are authenticated using the common secret information when contents are to be used, and contents only delivered if the authentication is successful, it is possible to prevent member devices that do not hold the common secret information (i.e. unregistered member devices) from using contents.

Abstract: A key delivery apparatus that prevents the improper use of contents, and manages a decryption key for decrypting an encrypted content and a suppliable number showing how many times the decryption key is suppliable, with respect to one or more terminal apparatuses connected to a network.

Abstract: A server apparatus encrypts content, based on a distribution key, and transmits the encrypted content to a PC via a network. The PC, to which a memory card is connected, outputs the received encrypted content to the memory card. The memory card decrypts the encrypted content using the distribution key, converts the data format of the decrypted content, encrypts the content using a medium unique key that is unique to the memory card, and records the resulting re-encrypted content internally. A playback apparatus decrypts the re-encrypted content using the medium unique key, and plays back the decrypted content.
