Patent number: 7782854Abstract: This invention constructs within the LAN a private area network (PAN) which is configured by terminal devices (personal computers and the like) of a specific group, is hardly influenced by the LAN traffic, and has high security. For this purpose, a PAN server which manages the communication route between specific terminals is installed within the LAN. The PAN server sets the communication route of each terminal device as label information, and causes switches and terminals to set pieces of label information generated for them. When the frame of data from a given port of each connection switch contains information representing PAN communication, the connection switch outputs the data to only a port specified by routing label information described in the frame.Type: GrantFiled: August 6, 2004Date of Patent: August 24, 2010Assignee: Canon Kabushiki KaishaInventors: Tsuguhide Sakata, Yukichi Niwa, Kenji Nakamura, Mitsuru Yamamoto, Noboru Yamamoto, Hiroyuki Yatsu

Publication number: 20070089901Abstract: A circuit board according to the present invention is so formed that an extension pattern not covered with an insulating film is provided at a NC land that does not allow an electric signal to pass therethrough, so as to have a configuration equivalent to that of a pattern not covered with the sulating film and provided at a land that allows the electric signal to pass therethrough. Accordingly, the NC land may have an exposed surface area equivalent to that of the land. Therefore, when a semiconductor component is soldered using solders, bumps of the solders at the NC land and at the land may be evenly formed, thereby providing coplanarity of the solders, and increasing soldering reliability for the semiconductor component.Type: ApplicationFiled: September 14, 2006Publication date: April 26, 2007Inventors: Hiroyuki Yatsu, Shuichi Takeda

Publication number: 20040090755Abstract: An electronic unit includes a module in which a semiconductor device is attached on the bottom of a circuit board and which has lands provided on the bottom of the circuit board, and a printed circuit board on which the module is mounted, the printed circuit board having a hole in a position facing the semiconductor device and having electrical conductors to which the lands are soldered. The module is mounted on the printed circuit board by soldering the lands to the electrical conductors while the semiconductor device is disposed in the hole. Accordingly, the electronic unit is smaller in height than conventional electronic units. Such a structure allows the module to be surface-mounted on the printed circuit board with solder paste, and thus high productivity of the electronic unit can be achieved.Type: ApplicationFiled: October 31, 2003Publication date: May 13, 2004Applicant: Alps Electric Co., Ltd.Inventor: Hiroyuki Yatsu
