  • Publication number: 20210009037
    Abstract: When a relationship between a distance from a rear camera to a target subject, and a ratio of a size of the target subject displayed on a monitor with respect to a size of the target subject reflected in a half-mirror, is determined while fixing an angle of view of the rear camera to a predetermined value, the angle of view of the rear camera is set such that a size of the target subject at an infinite distance in the relationship becomes a size that is 0.33 times to 0.5 times a size of the target subject that is reflected in the half-mirror.

  • Publication number: 20190366950
    Abstract: A vehicle control device includes an actuation unit that actuates an anomaly control switch that acknowledges execution of safety control, which improves safety during driving of a vehicle, upon detection of an occupant in an anomalous state from a monitoring result of a state of the occupant of the vehicle. The actuation unit causes the anomaly control switch to be actuated to allow the occupant to recognize a control content of the safety control. The vehicle control device further includes an operation acknowledgement unit that acknowledges operation of the anomaly control switch and a controller that executes the safety control when the operation acknowledgement unit acknowledges the operation of the anomaly control switch.

  • Patent number: 8431271
    Abstract: The invention provides a polyanion-based positive active material which can improve storage stability (especially, high temperature storage stability), charge and discharge cycle performance and the like of a lithium secondary battery, and a lithium secondary battery using the same. The positive active material for a lithium ion secondary battery contains lithium iron cobalt phosphate represented by the general formula: LiyFe(1-x)CoxPO4(0<x?0.019, 0?y?1.2). By using the positive active material for a lithium secondary battery, high temperature storage stability and charge and discharge cycle performance can be improved in comparison with a case where LiyFePO4 containing no Co is used. By using the positive active material, a lithium ion secondary battery can be suitable for applications in fields of electric automobiles and industrial batteries in which long lives, high capacities, and high output powers are required.

  • Patent number: 7825417
    Abstract: A technique for suppressing the bowing of an epitaxial wafer is provided. The epitaxial wafer is prepared by successively epitaxially growing a target group III-nitride layer, an interlayer and another group III-nitride layer on a substrate with a buffer layer. The interlayer is mainly composed of a mixed crystal of GaN and InN expressed in a general formula (GaxIny)N (0?x?1, 0?y?1, x+y=1) (or a crystal of GaN), and does not contain Al. The interlayer is epitaxially formed at a lower growth temperature than those of the group III-nitride layers, more specifically at a temperature in a range of at least 350° C. to not more than 1000° C.
