Patent number: 8449742Abstract: The gas sensor includes a sensor element having electrode pads formed in its electrode forming surfaces at the proximal end portion thereof, an insert-holding insulator insert-holding the sensor element, a housing insert-holding the insert-holding insulator, and a terminal unit. The proximal end portion of the sensor element is held by the terminal unit which includes a pair of proximal end insulators formed with metal terminals at their inner surfaces, and a spring member pressing the proximal end insulators in a direction that they approach each other. Each of the proximal end insulators includes an insulator contact portion in contact with one of the electrode forming surfaces. The insulator contact portion is located closer to the proximal end of the sensor element than a terminal contact portion at which the metal terminal contacts a corresponding one of the electrode pads.Type: GrantFiled: April 23, 2010Date of Patent: May 28, 2013Assignee: Denso CorporationInventors: Keiji Kanao, Kaneo Buma, Masato Ozawa, Hirofumi Noda, Kouichi Hirano

Patent number: 7389938Abstract: It is to provide a radio communication system capable of performing highly reliable reading/writing communication even though the RFID tags face in the random directions. The radio communication system comprises an RFID tag used for identification, a reader/writer for performing transmission and reception of information between the RFID tag by radio waves, and a plurality of reflecting plates in a space where a plurality of RFID tags are accumulated. The reflecting plates direct traveling direction of the radio wave irradiated from the reader/writer towards the RFID tags. A part of the radio waves irradiated from an antenna of the reader/writer is directed to travel three-dimensionally towards the space by the effect of the reflecting plates. Moreover, the radio waves traveling in the same direction among the reflected radio waves by the plurality of reflecting plates together allow attenuation caused due to distance to be reduced extremely.Type: GrantFiled: June 9, 2006Date of Patent: June 24, 2008Assignee: NEC CorporationInventors: Shigeru Hatakeyama, Shigeru Yamazaki, Hiroki Murayama, Kouichi Hirano
