Patent number: 7747621Abstract: The invention provides a system that associates data files with one another effectively to visually represent a relation among the data files and allows a user to easily understand relationship of contents of the data files. The system determines whether there is a parent data file for a selected retrieval object data file with reference to a contract association table and, if the parent data file is present, changes the retrieval object to the parent data file and repeats the processing. If the parent data file is not present, the system stores a present retrieval object data file as display data, that is, store a top data file as display data. Then, the system retrieves all data files associated with the top data file, stores the data files as display data, generates a relation diagram of the data files, and transmits the relation diagram to a user terminal.Type: GrantFiled: December 16, 2004Date of Patent: June 29, 2010Assignee: Canon Kabushiki KaishaInventors: Hisashi Sato, Yoshitaka Masuzawa, Mitsuhiro Yamamoto, Katsuya Yamashita, Hideyuki Fujiwara, Shigeto Nakayama

Patent number: 7608315Abstract: A high thermal conduction insulator exhibiting thermal conductivity, insulating properties and heat radiating properties is produced by supplying a molding material composed of an insulating resin, a diamagnetic material powder and a paramagnetic material (inclusive of ferromagnetic material) powder, and exhibiting fluidity into a mold, and applying a magnetic field to the molding material in the mold to orient clusters, each being composed of diamagnetic material particles of the diamagnetic material powder, which are joined together like a chain, along directions of lines of a magnetic force, and draw the paramagnetic material (inclusive of ferromagnetic material) powder with the magnetic force along one of mold surfaces of the mold, thereby forming a heat radiating layer. Heat transmitted from a facing member to one surface of the insulator is speedily transmitted to the other surface thereof via the clusters, and is effectively radiated from the heat radiating layer existing in the other surface.Type: GrantFiled: March 30, 2007Date of Patent: October 27, 2009Assignee: Toyoda Gosei Co., Ltd.Inventors: Yasunori Uchida, Hideyuki Fujiwara, Yoshiki Nakamura, Tadanobu Ota, Tatsuo Suzuki

Patent number: 7522187Abstract: An image input apparatus includes an image data generating unit, a data transfer unit and a control unit. The image data generating unit generates high resolution image data if the image input apparatus is in a high-resolution image mode, and generates low resolution image data if the image input apparatus is in a low resolution image mode. The data transfer unit tranfers the high resolution image data to an external device in an asynchronous or bulk transfer mode, and transfers the low resolution image data to the external device in an isochronous transfer mode. The control unit changes the low-resolution image mode to the high-resolution image mode, if an instruction for selecting the high-resolution image mode is received from the external device during the transfer of the low resolution image data.Type: GrantFiled: December 13, 2002Date of Patent: April 21, 2009Assignee: Canon Kabushiki KaishaInventor: Hideyuki Fujiwara

Patent number: 7391541Abstract: It is an object of the present invention to provide an excellent image reading apparatus that realizes miniaturization and reduces a total reading time at the time of reading a transparent original and, in addition, improves operability. In order to attain this object, since the image reading apparatus has a configuration in which a light source driving circuit section is disposed to overlap in the upward direction separating from an original mounting surface of a surface light emitting section, an area occupied by the light source driving circuit section and the surface light emitting section on a horizontal surface becomes small and miniaturization can be realized. In addition, since the light source driving circuit section and the surface light emitting section can be disposed in a position close to a hinge section altogether, the center of gravity of an FAU is moved to the hinge section side, and rotatability of the hinge section becomes easy and is improved.Type: GrantFiled: July 6, 2005Date of Patent: June 24, 2008Assignee: Canon Kabushiki KaishaInventors: Toshio Takahashi, Naofumi Sekine, Hideyuki Fujiwara, Kenichi Nanpei
