    摘要: An electrical connecting box suitable to widely-ranging temperature conditions from high temperature to low temperature inside the engine room of a vehicle is described, having a printed circuit board 300 and a first protecting member 100 and a second protecting member 200 housing the printed circuit board in a sandwich state. In this electrical connecting box an extended portion 310 being a part of electrical parts is formed upon a board surface 301 on the side of the first protecting member of the printed circuit board. Additionally, first pillar portions 110 and a second pillar portion 120 are formed upon the inside surface of the first protecting member facing one side of the board surfaces, and a tip 111 and a tip 121 of these pillar portions, according to bending of the first protecting member, can be in either a contacted state or a spaced state with respect to the board surface 301 or, alternatively, a projecting body 321 fixed to the board surface. When the first pillar portions are contacting the one side of the board surfaces, there is a gap between the extended portion and the inside surface of the first protecting member such that they do not interfere with each other.

    摘要: An ink-jet head includes pressure chambers arranged in a row in a row-direction, and a manifold flow passage communicated with the pressure chambers and extending in the row-direction. An ink inflow port is formed at one end of the manifold flow passage. The manifold flow passage has a main portion, a connecting portion, and an extended portion which are arranged in this order from a side close to the ink inflow port. The manifold flow passage is communicated with the pressure chambers at the main portion. The main portion has a constant cross-sectional area greater than that of the connecting portion. A cross-sectional area of the extended portion is greater than that of the connecting portion. The pressure wave, generated in the pressure chamber and propagated to the manifold flow passage, can be efficiently attenuated by the manifold flow passage constructed as described above.
