Patent number: 7394243Abstract: A proximity sensor 717 comprising a combination of an arbitrarily selected one of a plurality of types of detection end modules 707, a plurality of types of output circuit modules 709 and a plurality of types of outer shell cases 711. The detection end module 707 includes an integrated arrangement having a detection coil assembly (705, 701, 702) with the detection characteristic self-completed by a mask conductor 700 for reducing the conductor detection sensitivity in a specific peripheral area where the outer shell case is assumed to exist, and a detection circuit assembly (703) with the coil of the detection coil assembly as a resonance circuit element. The characteristics of the proximity sensor are completely adjusted before shipment. As a result, the adjustment of the characteristics which otherwise might be required each time is eliminated even in the case of the combination with an outer shell case of a different material.Type: GrantFiled: March 15, 2002Date of Patent: July 1, 2008Assignee: Omron CorporationInventors: Hiroyuki Tsuchida, Yasushi Matsuoka, Chikashi Niimi, Kazuhiro Hayashi, Kazuaki Miyamoto, Hiroyuki Fujinaga, Toru Aoki, Arata Nakamura, Kazushi Tanase, Koro Kitajima, Giichi Konishi, Masayuki Kono, Takashi Otsuka, Masayuki Kitanaka, Masahiko Shibayama, Yukio Yamaguchi

Patent number: 7145348Abstract: A coated electric wire is wound around a detection circuit in a planar manner for the purpose of electrostatic shield. This winding is performed, for example, spirally in a single layer. In the case where there are further provided a detection circuit board including a detection circuit and a cylindrical case, the coated electric wire is wound around the detection circuit board in a planar manner, wherein the direction of the axis of the cylindrical surface accords with the direction of the axis of the case. Consequently, there can be provided a sensor device in which the detection circuit can be electrostatically shielded with ease.Type: GrantFiled: October 31, 2003Date of Patent: December 5, 2006Assignee: Omron CorporationInventors: Takao Nakazaki, Hiroyuki Tsuchida, Koro Kitajima, Mitsuo Hatada, Kazuaki Miyamoto, Shinjiro Kotani, Kazushi Tanase, Masahiko Shibayama, Shoichi Konishi
