Abstract: The positive electrode active material for a lithium ion secondary battery contains a lithium-nickel-manganese composite oxide, in which metal elements constituting the lithium-nickel-manganese composite oxide include lithium, nickel, manganese, cobalt, titanium, niobium, and optionally zirconium, an amount of substance ratio of the elements is represented as Li:Ni:Mn:Co:Zr:Ti:Nb=a:b:c:d:e:f:g (provided that, 0.97?a?1.10, 0.80?b?0.88, 0.04?c?0.12, 0.04?d?0.10, 0?e?0.004, 0.003<f?0.030, 0.001<g?0.006, and b+c+d+e+f+g=1), in the amount of substance ratio, (f+g)?0.030 and f>g are satisfied.

Abstract: A linear motion converter is held by a caliper that holds a pad, and is capable of converting a rotation from the speed reducer into a linear motion and pressing the pad against a disk. An electronic circuit controls a rotation of an electric motor. A caliper-side speed reducer housing is provided to accommodate a portion of the speed reducer and to be connected to the caliper. A motor-side speed reducer housing is provided to accommodate a portion of the speed reducer and to be connected to the caliper-side speed reducer housing. The electric motor is provided on the caliper-side speed reducer housing side with respect to the motor-side speed reducer housing. The electronic circuit is provided on the opposite side of the motor-side speed reducer housing to the caliper-side speed reducer housing. A thermal conductivity of the caliper-side speed reducer housing is lower than the motor-side speed reducer housing.

Abstract: The vehicular display control device which controls an image that is projected on a windshield of a vehicle, includes: a detection section which detects an object near the vehicle; and a display control section which displays, when a first object is detected in front of the vehicle, a first image for attracting attention to the first object, at a predetermined position in a first region on the windshield, and displays, when a second object is detected on a lateral side relative to, or behind, the vehicle, a second image for attracting attention to the second object, at a predetermined position in the first region. When determining that a display position of the second image overlaps, in the first region, with a display position of the first image, the display control section moves the second image from the first region to a second region on the windshield.
