A defect-free hydrogen separation membrane includes a metal thin membrane. The metal thin membrane includes a first metal layer composed of palladium on a porous support without substantial penetration into surface pores of the porous support and a second metal layer on the first metal layer. The second metal layer is a product of palladium deposition and closes defects being open on the surface of the first metal layer.

A printed circuit board assembly has plural printed circuit boards that are mechanically and electrically connected to each other with them being stacked, and a connection layer that connects the adjacent two printed circuit boards to each other is provided. The connection layer includes an insulation portion and an electric conduction portion. The insulation portion contains an insulating member and is adhered to each of the adjacent two printed circuit boards. The electric conduction portion passes through the insulation portion and connects electrode terminals of the adjacent two printed circuit boards.

An injector comprises an injection nozzle 1 having a nozzle hole 3, a valve body 2 for controlling a fuel flow through the nozzle hole 3, and changing means 6, 7, 10, 11, 12, 13, 20 for changing a shape of fuel spray, the fuel spray being formed by the fuel which flows through the nozzle hole. The injector includes rotation preventing means for preventing the valve body 2 from rotating with respect to the injection nozzle 1 around a center axis of the valve body 2. The injector includes angular displacement controlling means for controlling an angular displacement of the valve body 2 with respect to the injection nozzle 1. A shape of a tip of the valve body 2 is circumferencially non-uniform.
