  • Publication number: 20170124514
    Abstract: A project management system includes obtains an edit period of time of each of a plurality of files serving as a product of a project. The edit period of time ranges from a start of creation to a last update, and a grouping unit selects a second file whose creator and updater are the same as a creator of a first file included in meta information specifying each of the plurality of files and an updater of the first file included in an access log to the plurality of files and whose edit period of time at least partially overlaps the edit period of time of the first file. The first file and the selected second file are grouped, and the edit periods of time of the first file and the second file are output in association with the first file and the second file.

  • Patent number: 8437604
    Abstract: To improve the convenience of a record medium and allow a record process and reproduction process to be more easily performed than before. When a clip edit list update process 121 that updates video data and audio data recorded on a disc 32 is executed, an index file management section 72 manages and updates an index file held in an index file hold section 51 as the video data and audio data are updated. At this point, a search section 92 searches disc internal IDs assigned to clips or edit lists contained in the index file for the maximum value. A disc internal ID generation section 91 generates a disc internal ID according to the maximum value. An index file management section 72 updates the index file with the disc internal ID generated by the disc internal ID generation section 91.

  • Patent number: 8247137
    Abstract: Separators (5A, 5B, 6) and membrane-electrode assemblies (2) of a fuel cell stack (1) are alternately stacked in a guide box (40). The separators (5A, 5B, 6) each have groove-like gas paths (10A, 10B). Powder of an adhesive agent (7) is adhered in advance to the surfaces of the separators (5A, 5B, 6), except the gas paths (10A, 10B), through photosensitive drums (31A, 31B) to which the powder is adsorbed in a given pattern. The separators (5A, 5B, 6) and the membrane-electrode assemblies (2), stacked in the guide box (40), are heated and compressed by a press (43) and heaters (40C) to obtain a unitized fuel cell stack (1).

  • Patent number: 8085317
    Abstract: A data generation section generates an essence data file composed of a file header, a file body, and a file footer. A header size obtainment section obtains header size information of essence data file from the data generation section, and supplies the header size information to a clip generation section and an index file update section. The clip generation section generates a clip information file that describes the header size information supplied from the header size obtainment section. The index file update section registers a clip element that describes the header size information supplied from the header size obtainment section to an index file stored in a ROM.

  • Publication number: 20070154628
    Abstract: This invention relates to a manufacturing method for a polymer electrolyte fuel cell which is formed by laminating a first gas diffusion layer (6A) and a first separator (7A) on one surface of a membrane electrode assembly (9), and laminating a second gas diffusion layer (6B) and a second separator (7B) on the other surface of the membrane electrode assembly (9). An adhesive is applied to a surface of the first separator (7A) which contacts the first gas diffusion layer (6A), the adhesive is applied to a surface of the second separator (7B) which contacts the second gas diffusion layer (6B), and the first separator (7A), first gas diffusion layer (6A), membrane electrode assembly (9), second gas diffusion layer (6B), and second separator (7B) are disposed between a pair of pressing jigs (113, 123) so as to be laminated in the described sequence. An integrated fuel cell is obtained by applying heat and compression to the first separator (7A) and second separator (7B) using the pressing jigs (113, 123).
