  • Patent number: 9650223
    Abstract: A carrying apparatus carries a battery electrode member (an electrode material film web or an electrode film). The carrying apparatus includes a carrier for holding while curving, and then carrying the electrode member. The carrier is configured to hold the electrode member at a position that doesn't cause a contact with components for another process at a downstream along a carrying direction. Since the electrode member is curved, its stiffness along the carrying direction is strengthened and thereby sagging down is prevented. In addition, the holding position by the carrier is the position that doesn't cause a contact with components for another process at a downstream along a carrying direction. Therefore, according to the carrying apparatus, it is possible to carry the electrode member (an end of an electrode material web or an electrode) to a target position reliably.

  • Patent number: 9643599
    Abstract: A vehicle control device includes a sensor and a controller. The sensor detects wheel speed. The controller estimates sprung mass state based on detected information in a prescribed frequency range. The controller controls a variable-damping force shock absorber to bring the estimated sprung mass state to a target sprung mass state. The controller estimates wheel rim braking/drive torque acting on a wheel. The controller determines the estimation accuracy of the sprung mass state has deteriorated when a rate of change of a stationary component extracted from components of wheel rim braking/drive torque acting on a wheel is detected to equal or exceed a prescribed value. The controller controls the variable-damping force shock absorber to a more limited extent than when the estimation accuracy has not deteriorated.

    Abstract: A method controls synchronization of a pinion rotating on a primary shaft driven by a traction machine of a vehicle and rotatably connected to a secondary shaft of a parallel shaft gearbox without synchronization mechanisms. The method includes sending to the traction machine, before coupling of the pinion on the primary shaft, a torque command which depends on a torque signal calculated to minimize a difference between a primary speed and a secondary speed multiplied by a reduction ratio between the primary shaft and the secondary shaft. The calculated torque signal is limited in amplitude when the speed difference is greater in absolute value than a desired accuracy on the targeted primary speed upon completion of the synchronization. The calculated torque signal is saturated on a maximum or minimum torque of the traction machine if the calculated torque signal is not between the maximum or minimum torque.

  • Patent number: 9630235
    Abstract: A roller hemming processing apparatus adapted to perform a hemming processing has a hemming die, on which a panel-like workpiece having a hemming flange portion on a periphery portion thereof, is positioned and supported, a roller hemming processing tool that is moved along a longitudinal direction of the hemming flange portion to bend the hemming flange portion at a root portion thereof while pressing the hemming flange portion toward the hemming die, and a nesting block disposed at a part of the periphery of the hemming die. The nesting block performs positioning of the workpiece by being brought into contact with the root portion of the hemming flange portion with which the workpiece is formed. The nesting block is elastically supported to be retractable in the pressing direction and to be swingably displaceable in the longitudinal direction of the hemming flange portion.

  • Patent number: 9630564
    Abstract: A compartment housing defines a compartment opening. A pivoting structure is disposed within the compartment housing for pivoting movement about a pivot axis that extends through the compartment housing. The pivoting structure has first, second and third walls that extend away from the pivot axis. Distal edges thereof are spaced apart from one another relative to a circumferential direction about the pivot axis. The pivoting structure pivots between a first orientation and a second orientation. In the first orientation: the first and second walls are exposed thru the compartment opening; the third wall is concealed within the compartment housing; and a storage space between the second and third walls is concealed within the compartment housing. In the second orientation: the second and third walls, and the storage space are exposed thru the compartment opening; and the first wall is concealed within the compartment housing.
