Abstract: When it is confirmed that a user exists based on an image of the situation outside a vehicle which is captured using a camera and a proximity sensor detects a fact that the user is approaching based on, for example, a putting of a hand of the user over the proximity sensor, a control device causes a ramp to be extended. As such, a user sitting in a wheelchair can cause the ramp to be extended by approaching the proximity sensor, such as the putting of the user's hand over the proximity sensor such that the user sitting in the wheelchair does not have to press an extension/storage button provided on the vehicle to cause the ramp to be extended.

Abstract: A bonded body has a supporting substrate composed of silicon, a piezoelectric material substrate, and a bonding layer provided on a surface of the supporting substrate and composed of silicon oxide. The bonding layer has a refractive index of 1.468 or higher and 1.474 or lower.

Abstract: An electric motor vehicle comprises a charging port which is opened in a vehicle side portion and opened/closed by a charging lid, a charging inlet which is arranged inside the charging port and has a connection unit connectable to an outside power source, and on-vehicle liquid tank which is arranged in the vicinity of the charging port and provided with liquid level indication of the stored liquid amount. The charging port has therein check hole which is opened to check the liquid level indication.

Abstract: According to the embodiment of the present invention, a guide vane of a water turbine rotatable about an axis, including a guide vane for directing supplied flowing water toward the downstream side. The guide vane has a downstream end edge having an upper end portion and a lower end portion. The lower end portion of the downstream end edge is displaced in the direction orthogonal to an axis with respect to the upper end portion of the downstream end edge when viewed from the downstream side.
