  • Patent number: 11852850
    Abstract: The present disclosure describes lighting assemblies (e.g., taillight assemblies) for vehicles that diffuse and block light transmission from a centralized light source, which inhibits (if not entirely prevents) the creation and perception of hotspots from one or more points-of-view (e.g., from the sides and/or the rear of the vehicle) while producing a more homogenous overall appearance. In one embodiment of the disclosure, the lighting assembly includes: a light source; a diffuser that is spaced axially from the light source; a lens that is spaced axially from the diffuser; and a shield that is located axially between the diffuser and the lens. The diffuser includes first and second lateral ends and is configured to receive and disperse light from the light source through the lighting assembly. The shield is configured to interfere with light transmission from the light source through the at least one lens and thereby inhibit hotspot perception.

  • Patent number: 11837691
    Abstract: A battery manufacturing method includes forming a unit cell having a positive electrode that is obtained by a positive electrode active material layer containing an electrolytic solution being disposed on a positive electrode current collector, a negative electrode that is obtained by a negative electrode active material layer containing an electrolytic solution being disposed on a negative electrode current collector, and a separator interposed between the positive electrode and the negative electrode. The battery manufacturing method further includes applying pressure to one unit cell or with two or more stacked unit cells from the stacking direction, and charging the one unit cell or the two or more stacked unit cells after applying of the pressure. The method is performed such that the positive electrode and the negative electrode are formed without an application film being subjected to a drying process performed through heating.

  • Patent number: 11830364
    Abstract: A driving assist method reduces a possibility of missing an opportunity to correct a host vehicle position set on map data. In the driving assist method using a controller that sets a target inter-vehicular distance from a host vehicle to a preceding vehicle, whether there is a request to execute a correction of a host vehicle position set on electronic map data is determined based on a result of comparing position information on a road sign described on the electronic map data with position information on the road sign acquired by using a camera installed in the host vehicle. If an execution request has not been made, the target inter-vehicular distance is set to a preset first target inter-vehicular distance. If an execution request has been made, the target inter-vehicular distance is set to a second target inter-vehicular distance, which is longer than the first target inter-vehicular distance.

  • Patent number: 11827985
    Abstract: A film forming method forms a coating film on a workpiece (e.g., a cylinder head) having a film-deposited portion (e.g., an annular valve seat part) by moving a nozzle of a cold spray device relative to the workpiece along a film formation trajectory having a film formation starting point and a film formation finishing point in which the film-deposited portion overlaps to form an overlapping portion. The coating film is formed by causing a raw material powder to collide in a solid-phase state with the workpiece and plastically deform. Also, the coating film on the film-deposited portion is further formed such that an inclination angle of an end part of the coating film relative to a surface of the film-deposited portion is 45° or less at the film formation starting point of the overlapping portion.
