  • Publication number: 20220258794
    Abstract: Control calculation units of a back system in each actuator operate by a collaborative drive mode in which a torque is output to a motor drive unit by using an information transmitted and received mutually by a communication between the systems in common. Cooperative control calculation units in a reaction force actuator and a turning actuator can operate in cooperation with each other based on the information transmitted and received mutually by a communication between actuators. A communication between adjacent systems and a communication between adjacent actuators are restored, when a focus control calculation unit is restored, after the focus control calculation unit is stopped during operation and at least one of the communication between adjacent systems or the communication between adjacent actuators is interrupted.

  • Publication number: 20220255473
    Abstract: A first actuator and a second actuator each have a plurality of control calculation units provided redundantly and a plurality of motor drive units provided redundantly. In the first and the second actuators, the control calculation units of the systems paired with each other transmit and receive information to and from each other by a communication between the actuators. When a failure occurs in any system in either of the two actuators, or when a failure occurs in a communication between actuators in either system, the control calculation unit of each actuator of the system in which the failure occurred stops the motor drive control. Then, the motor drive control is continued by the control calculation unit of the normal system in both actuators.

  • Patent number: 10276855
    Abstract: In a method of manufacturing a lithium-ion secondary battery electrode sheet proposed herein, a current collector (11), a powder material (13) of granulated particles, and a binder solution (12) are prepared. The binder solution (12) is applied onto the current collector (11). Subsequently, the powder material (13) of the granulated particles is fed onto the current collector (11). (Then, the powder material (13) of the granulated particles is pressed against the current collector (11). In the basic manufacturing method, adhesive strength of the powder material (13) of the granulated particles is enhanced after the powder material (13) of the granulated particles is fed onto the current collector (11) and before or while the powder material (13) of the granulated particles is pressed against the current collector (11).

  • Patent number: 10084179
    Abstract: Provided is a technique capable of evenly smoothing powder supplied to the surface of a supply member. A powder coating apparatus includes a pair of press rollers, hoppers, and squeegee rollers disposed such that prescribed gaps are formed between the squeegee rollers and the press rollers, and adjusting thickness of the powder by smoothing the powder supplied to each outer circumferential surface of the press rollers. The powder coating apparatus presses the powder, smoothed by the squeegee rollers, between the press rollers to form compressed powder layers on both the surfaces of the web. The squeegee roller is formed in a column having an axis being parallel to the outer circumferential surface of the press roller and being orthogonal to a moving direction of the outer circumferential surface of the press roller.
