Patent number: 8264311Abstract: A magnet unit includes a first magnetic pole (7a), a second magnetic pole (7b) and a third magnetic pole (7c) at a center between the first magnetic pole (7a) and the second magnetic pole (7b), providing an E-shaped configuration. In the magnet unit, a first magnet is defined between the first magnetic pole (7a) and the third magnetic pole (7c) by connecting two electromagnets (71aa, 73aa) with each other through a permanent magnet (72a), while a second magnet is defined between the second magnetic pole (7b) and the third magnetic pole (7c) by connecting two electromagnets (71ba, 73ba) with each other through a permanent magnet (72b). With this configuration, it is possible to reduce a deviation in the length of respective magnetic paths from the permanent magnets (72a, 72b) up to their respective magnetic poles. By controlling exciting currents to the respective electromagnets (71aa, 73aa, 71ba, 73ba), it is also possible to adjust fluxes (or flux density) in respective directions x, y individually.Type: GrantFiled: March 18, 2011Date of Patent: September 11, 2012Assignee: Toshiba Elevator Kabushiki KaishaInventors: Hiroaki Ito, Mimpei Morishita, Yosuke Tonami

Publication number: 20070200653Abstract: A needle 2 includes a plunger member 21 and a collar member 22, and is provided to be reciprocable from a latch position to a latch release position inside a stator 1. A first magnet coil 31 has sufficient electromagnetic power to put in a latch state the needle 2 which is in a latch release state on energization. A permanent magnet 4 has sufficient absorption power for absorbing a collar member 22 of the needle 2 put in the latch state by the electromagnetic power of the first magnet coil 31 and maintaining the latch state even when the first magnet coil 31 is in a non-energized state. A second magnet coil 32 can diminish magnetic fluxes of the permanent magnet 4 and change the needle 2 from the latch state to the latch release state on energization. Thus, energy efficiency is improved by varying how to energize the magnet coils according to the state of a load side.Type: ApplicationFiled: February 23, 2007Publication date: August 30, 2007Applicant: KABUSHIKI KAISHA TOSHIBAInventors: Yasuhiro Matsumoto, Yosuke Tonami, Yoshinobu Ishikawa, Nobutaka Kubota, Takeshi Noda, Kazuhiro Matsuo, Kenji Kato, Mitsutaka Homma, Takao Wakabayashi
