  • Patent number: 11971569
    Abstract: There is provided a light emitting device that can be used as a light guide plate and has an excellent antireflection function to extraneous light, and an optical body includes: a base material; a macro concave-convex structure that is formed on one surface of the base material and emits internally propagating light that is injected in an inside of the base material from a side surface of the base material, from another surface of the base material; and a micro concave-convex structure formed periodically to follow each of both surfaces of the base material and a surface of the macro concave-convex structure, and having an average period of concavity and convexity of less than or equal to a wavelength of visible light. The surface of the macro concave-convex structure has an inclined surface, and an arrangement of the micro concave-convex structure is a zigzag arrangement.

  • Patent number: 11958465
    Abstract: The vehicle control system includes a braking force generating device (6, 22) configured to generate a braking force to shift a load of a vehicle to a side of front wheels thereof at an initial stage of a cornering, and a control device (31) configured to control the braking force generated by the braking force generating device. The control device calculates an additional deceleration (Gxadd) according to vehicle state information, calculates a lateral jerk equivalent value (Jy) according to the vehicle state information, and sets a lateral jerk correction coefficient (Kj) for weakening the additional deceleration. The control device corrects the additional deceleration by the lateral jerk correction coefficient (K), and calculates an additional braking force (Fbadd) to be generated by the braking force generating device according to the corrected additional deceleration.

  • Patent number: 10919391
    Abstract: A cooling apparatus includes: a cooling circuit that includes three flow passages intersecting at an intersection point and allows a cooling liquid to circulate therethrough; a three-way valve that is disposed at the intersection point and is switchable such that any two of the three flow passages communicate with each other; and a controller that controls switching of the three-way valve. The controller includes an intermediate fixation determination unit. The intermediate fixation determination unit determines that the three-way valve is in an intermediate fixation state in which the three flow passages simultaneously communicate with one another, when a cooling liquid temperature difference between one of the two flow passages that are controlled to communicate with each other, and a remaining flow passage of the three flow passages that is not controlled to communicate, is smaller than a predetermined value.

  • Publication number: 20180321000
    Abstract: A cooling apparatus 1 includes: a cooling circuit 100 that includes three flow passages intersecting at an intersection point and allows a cooling liquid to circulate therethrough; a three-way valve 8 that is disposed at the intersection point and is switchable such that any two of the three flow passages communicate with each other; and a controller 9 that controls switching of the three-way valve 8. The controller includes an intermediate fixation determination unit. The intermediate fixation determination unit determines that the three-way valve is in an intermediate fixation state in which the three flow passages simultaneously communicate one another, when a cooling liquid temperature difference between one of the two flow passages that are controlled to communicate with each other, and a remaining flow passage of the three flow passages that is not controlled to communicate, is smaller than a predetermined value.
