Abstract: A human machine interface is configured to select an information display destination from among a plurality of display areas. The HCU acquires a sight line direction of a driver based on an image of an in-vehicle camera. The HCU displays, upon detecting a hop-off action of the driver based on an output signal of an in-vehicle sensor in a situation in which an attention target event such as a puddle, a step, other vehicle or the like exists on a road surface near a door of a driver's seat, in the display area corresponding to the driver's sight line direction, text or an image practically indicating (a) a content of an attention target event or (b) how to deal with a situation.

Abstract: Disclosed is an LED illumination device of a simple configuration, capable of suppressing thermal resistance to a low level, and of effectively dissipating heat generated from LED elements. Rigidity of a mounting plate is ensured by a wall of a certain height, and thereby the mounting plate now becomes possible to endure saturation vapor pressure of a coolant liquid possibly exerted thereon, and vacuum state or near-vacuum state when the coolant liquid is injected, without being deformed. Since the rigidity of the mounting plate is ensured by the wall, a wall composing a bottom face of recesses may now be thinned, and this is advantageous in view of allowing the heat generated from the LED elements to effectively conduct to the coolant liquid, and of effectively cooling the LED elements.

Abstract: The present invention relates to a spraying unit for unhardened concrete and the like, which is provided with an apparatus capable of mixing a constant quantity of quick-set additive, for example, into unhardened concrete to be sprayed.The apparatus capable of mixing the constant quantity of quick-set additive into unhardened concrete and the like is adapted to usually carry and supply the constant volumetric weight and quantity of quick-set additive outside a quick-set additive container regardless of the amount of the quick-set additive stored inside the container.
