The present invention discloses a connector and an LED light bar. A transistor including an oxide semiconductor film, which has excellent on-state characteristics is also provided. An array of pads are formed on a first side of the interface board, each pad having a controlled surface associated with one of the pass throughs. A screw screwed into the face-side end of the first hinge wing axially displaces the shaft by a predetermined extent out of the preassembled position into the operative position. The absorbent product has been shown to have improved rewet characteristics.
