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

Patent number: 7564164Abstract: A piezoelectric element of the piezoelectric pump is driven by the output signal of an amplifier that takes as input a signal that is generated by a sine wave oscillator of the same frequency that drives the piezoelectric element. The amplifier is driven by a high voltage obtained by conversion from a low-voltage power supply by a voltage-boosting converter, whereby the piezoelectric element is driven by a low-frequency sine wave of high voltage. The frequency of the sine wave oscillation is further adjusted by a signal from a first control circuit at the time of activation. In addition, the amplitude of the sine wave oscillation is adjusted by the output signal of a second control circuit that takes as input a signal from temperature sensor for sensing the temperature of the heat-generating body.Type: GrantFiled: February 1, 2005Date of Patent: July 21, 2009Assignee: NEC CorporationInventors: Mitsuru Yamamoto, Sunao Hamamura, Yasuhiro Sasaki, Sakae Kitajo
