  • Patent number: 9970751
    Abstract: An optical axis angle inspection device is provided with a first camera and a screen which are disposed in front of a laser distance meter, is provided with a point light source on the screen, and is provided with a second camera disposed behind the laser distance meter. An image of the laser distance meter is captured by the first camera, and the height of the point light source is fitted to the height of the laser distance meter on the basis of the captured image. Then, an image of the point light source is captured by the second camera, and a difference in height between the centroid of the captured image and the point light source is specified. The optical axis angle of the laser distance meter is calculated from the difference in height and the distance from the screen to the laser distance meter.

  • Patent number: 9966517
    Abstract: An LED leadframe or LED substrate includes a main body portion having a mounting surface for mounting an LED element thereover. A reflection metal layer serving as a reflection layer for reflecting light from the LED element is disposed over the mounting surface of the main body portion. The reflection metal layer comprises an alloy of platinum and silver or an alloy of gold and silver. The reflection metal layer efficiently reflects light emitted from the LED element and suppresses corrosion due to the presence of a gas, thereby capable of maintaining reflection characteristics of light from the LED element.

  • Patent number: 9859709
    Abstract: A power control apparatus is applied to a vehicle provided with a receiving port connected with an external power supply device placed outside the vehicle and on-vehicle electrical loads including a second battery which stores power supplied from the external power supply device via the receiving port. The power control apparatus for vehicles has power supply processing means that performs a power supply process for supplying desired power to the loads during a stop of the vehicle. This power supply processing means predicts cost required to supply the desired power, based on future predicted power cost information, in planning a power supply process needed during the stop of the vehicle. This planned power supply process is performed.
