  • Patent number: 12233936
    Abstract: A vehicle steering apparatus is configured to apply, to a steered wheel of a vehicle, a driving force for canceling a toe change amount caused by a road irregularity. The vehicle steering apparatus includes a road reaction force detector configured to detect a road reaction force received by a tire of the steered wheel, a toe adjustment actuator coupled to the steered wheel, and a controller configured to control a driving force of the toe adjustment actuator. The controller includes a toe change amount setter configured to set the toe change amount based on the road reaction force detected by the road reaction force detector, an operation amount calculator configured to calculate an actuator operation amount for canceling the toe change amount set by the toe change amount setter, and a driver configured to drive the toe adjustment actuator by the actuator operation amount calculated by the operation amount calculator.

  • Patent number: 12208678
    Abstract: A front-rear wheel driving force distribution device includes a center differential and a limited slip differential. The limited slip differential includes a first clutch, a second clutch, a first piston, a second piston, and a one-way clutch provided between the first clutch and a rear propeller shaft. If the second clutch is engaged by the second piston, the propeller shaft on the rear side rotates at increased speed as compared with a case where the first clutch is engaged by the first piston. The one-way clutch couples the first clutch and the rear propeller shaft if a number of rotations of the first clutch is same as or higher than a number of rotations of the rear propeller shaft, and idles if the number of rotations of the first clutch is lower than the number of rotations of the rear propeller shaft.

  • Patent number: 12148934
    Abstract: A method for producing a metal composite oxide, the method including steps of: preparing a slurry by mixing different kinds of metal compounds in a powder form, a dispersion medium, and a dispersant, and baking the different kinds of metal compounds after the dispersion medium in the slurry is removed. The slurry further includes a polyalkylene oxide having a viscosity average molecular weight of 150,000 or more. The slurry has a viscosity of 10 mPa·s to 2000 mPa·s, the viscosity being measured using a B-type viscometer under conditions of a temperature of 23° C. to 27° C. and a rotation rate of 60 rpm. According to the production method, a slurry in which different kinds metal compound powders are uniformly dispersed and a precipitate is unlikely to be formed can be obtained.

  • Patent number: 7619161
    Abstract: The present invention relates to a grounding device in which a grounding member E having a grounding conductor 2 and a conductive laminated portion 5 covering the grounding conductor 2 is integrated with a foundation member B of a building so that the grounding member E and the foundation member B overlap partly or entirely. The grounding device is configured so that the grounding member having the grounding conductor and the conductive laminated portion covering the grounding conductor is integrated with the foundation member of the building are so that the grounding member and the foundation member overlap partly or entirely. This makes it possible to easily offer a small grounding resistance. Further, the foundation member of the building contacts the earth over a large area. This enables a small grounding resistance to be stably offered for a long period.

  • Patent number: 7385140
    Abstract: A grounding conductor 1 is composed of a conductive metal portion 2 and a conductive casing portion 3 that covers the conductive metal portion 2. The conductive casing portion 3 has a specific resistance of 0.01 to 0. (?·m). Since the grounding conductor 1 is composed of the conductive metal portion 2 and the conductive casing portion 3 that covers the conductive metal portion 2, the conductive metal portion 2 is connected to the earth via the conductive casing portion 3. The conductive metal portion 2 does not contact directly with the earth but is electrically connected to the earth via the conductive casing portion 3. This prevents the conductive metal portion 2 from being corroded. It is also possible to avoid a disconnection in the conductive metal portion 2.
