Abstract: A matrix type ultrasonic probe is disclosed, which has a backing material, and a plurality of piezoelectric elements having upper and lower face electrodes, respectively, and arrayed in two-dimensional directions on the backing material. The ultrasonic probe further has first mounts provided for every piezoelectric element and fixedly secured to the backing material, signal lines provided for every piezoelectric element and embedded in the backing material to be exposed on the surface of the respective first mounts, and second mounts provided for every piezoelectric element to be fixedly secured to the lower face of the piezoelectric element and formed therein with through-holes. The first and second mounts are fixedly secured to one another by means of conductive adhesive, and the signal lines and the lower face electrodes are electrically connected to one another by means of the conductive adhesive.

Abstract: In a roof structure for a vehicle, a side outer member and a roof member are combined at their side portions to provide a groove extending over at least midway of a boundary between the side outer and roof members. Each of the side outer and roof members comprises has exposed and unexposed surface portions: each of the unexposed surface portions has an inward bend and a lower margin. The side outer and roof members are overlapped at their exposed surface portions to provide an overlap such that a corner defined by the exposed and unexposed surface portions of the roof member is substantially aligned with a corner defined by the exposed and unexposed surface portions of the side outer member. The unexposed surface portions of the side outer and roof members are diagonal toward a center of a roof in a widthwise direction of the roof as they are away from the corners. At least one of the inward bends and lower margins of the side outer and roof members has a lug for overlap to provide a partial overlap.
