Patent number: 7805279Abstract: Factories (102-104) have host computers (107) for monitoring industrial equipment (106). Each host computer (107) is connected to a management host computer (108) on a vendor (101) side through the internet (105). The host computer (107) on the factory side detects occurrence of a trouble of the industrial equipment (106) and notifies the vendor side of status information representing a trouble state. In response to this, the host computer (108) on the vendor side notifies the factory side of response information representing a countermeasure against the trouble state.Type: GrantFiled: May 23, 2006Date of Patent: September 28, 2010Assignee: Canon Kabushiki KaishaInventors: Nobuaki Ogushi, Hirohisa Ohta, Yoshito Yoneyama, Masaya Ogura

Patent number: 7348698Abstract: A rotor having magnets composed of rare-earth magnets is rotatably disposed inside an exterior casing, a penetrating aperture is disposed through a first end of the exterior casing relative to a direction of a motor central axis, and a filter is disposed so as to cover the penetrating aperture from a second end of the exterior casing relative to the direction of the motor central axis. A shaft is mounted to a bush by screwing an external thread portion into an internal thread portion. An operating member is mounted integrally onto a second end portion of the shaft projecting outward from a penetrating aperture in a housing. A rotation-regulating projection portion of a guide member fixed to the shaft is fitted loosely into a guide groove disposed so as to extend along an inner wall surface of a central aperture of the housing in the direction of the motor central axis.Type: GrantFiled: October 7, 2003Date of Patent: March 25, 2008Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Hirohisa Ohta, Satoru Tokiya, Masayasu Miyajima, Shuzo Isozumi

Patent number: 6927507Abstract: A stepping motor being a motor used in oil includes a coil formed with a conductor coated with an outer coating and wound around a bobbin, and coil terminals electrically connected to the conductor at ends thereof led out from the coil, the outer coating being removed from the conductor at the ends thereof. The coil terminals are coated with a protective film made of a material having low permeability to elemental sulfur and sulfur compounds. Therefore, coil terminals and ends of the conductor are prevented from erosion by sulfur and organic sulfur compounds, thereby reducing risk of disconnection in the coil terminals and the conductor.Type: GrantFiled: September 24, 2001Date of Patent: August 9, 2005Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Naoya Hashimoto, Teruo Miyaoku, Shiro Hasegawa, Chiaki Sugano, Hiromasa Ozawa, Hirohisa Ohta
