Patent number: 10020720Abstract: Described herein are latching devices where relative speed of movement between members is in part controlled or reduced via eddy current formation and in part controlled or relative motion stopped via a latch arrangement. Various embodiments are described, one being use of a conductive member; at least one magnetic field and a latch member that, prior to latching, moves independently to the at least one conductive member. A kinematic relationship exists between the conductive member and at least one magnetic field that enables the conductive member to move at a different speed relative to the magnetic field on application of an energizing force, thereby inducing an eddy current drag force by relative movement of the conductive member in the magnetic field. The eddy current drag force resulting causes movement of the conductive member causing the conductive member to engage the latch member thereby halting movement between the at least one conductive member and the at least one latch member.Type: GrantFiled: August 18, 2015Date of Patent: July 10, 2018Assignee: EDDY CURRENT LIMITED PARTNERSHIPInventors: Andrew Karl Diehl, Christopher James Allington, Kevin Andrew Wright

Patent number: 10014746Abstract: In a rotary electric machine, wound wires are connected to a first terminal and a second terminal. Circuit terminals that are configured from a conductive metal other than aluminum, and the first terminal and the second terminal that are configured from a metal with a principal component of aluminum are joined together inside a circuit chamber that has high water resistant properties. Corrosion is accordingly suppressed at join sites of the circuit terminals with the first terminal and the second terminal. There is therefore no need to coat the join sites with for example a sealing material in order to suppress corrosion at the join sites. Good electrical continuity is accordingly enabled between the circuit terminals and the wound wires while suppressing an increase in costs, even when the wound wire is configured from a metal with a principal component of aluminum.Type: GrantFiled: August 2, 2017Date of Patent: July 3, 2018Assignee: ASMO CO., LTD.Inventors: Hidenori Kanda, Shigeaki Kageme, Takahiro Nakayama, Yoshiyuki Takabe
