  • Publication number: 20180205281
    Abstract: In a process of manufacturing a motor, a terminal pin is first attached to an insulator of a stator. Next, an end portion of a conducting wire defining a coil is drawn out toward the terminal pin, and the conducting wire is wound around the terminal pin. Next, the conducting wire is soldered to the terminal pin. Thereafter, injection molding of a casing is performed with the stator as an insert. At this time, a mold is brought into contact with an upper surface of the insulator to surround the terminal pin with the mold. Thus, a contact of the mold with the conducting wire wound around the terminal pin is prevented. This reduces the likelihood that the conducting wire will be damaged.

  • Patent number: 8989981
    Abstract: There is provided a vehicle drive control system that feels less unnatural and that enables an improvement in safety performance. A vehicle motion control system capable of independently controlling a driving force and a braking force of four wheels comprises: a first mode (G-Vectoring control) in which substantially the same driving force and braking force are generated with respect to left and right wheels among the four wheels based on a longitudinal acceleration/deceleration control command that is coordinated with the vehicle's lateral motion; and a second mode (sideslip prevention control) in which different driving forces and braking forces are generated with respect to the left and right wheels among the four wheels based on a target yaw moment derived from the vehicle's sideslip information, wherein the first mode is selected when the target yaw moment is equal to or less than a pre-defined threshold, and the second mode is selected when the target yaw moment is greater than the threshold.

  • Patent number: 8743286
    Abstract: A peripheral control system enhances expandability in the operation of peripheral by enabling the customization and display of operation panels for each of the peripherals, regardless of whether any operation panel exists at the display device side. The peripheral control system is configured by connecting a TV and a recorder via an HDMI connection. The TV stores operation panel information that includes array information for arraying, on the screen, image data of the operation buttons that comprise the operation panel of the recorder. The recorder stores image data of the operation buttons, and sends, according to operation panel information obtained from the TV, the aforementioned stored image data of the operation buttons in association with the array information to the TV. The TV disposes and displays image data of the operation buttons sent from the recorder, at a position that is in accordance with the array information.
