Abstract: To provide a sheet formed product that, in addition to being thin, has a small groove interval, groove width, and groove depth, that has a large contact surface area with oxygen gas or hydrogen gas, that is suitable for simply and at low cost producing a lightweight compact separator, and a manufacturing method for same. In the sheet formed product (amorphous thin sheet) according to the present invention, a metal matrix on which is formed a passivation layer on a surface layer thereof and that exhibits corrosion resistance has a three-dimensional surface structure, for example a groove-like uneven shape on a surface thereof. On the front surface having the uneven shape (or also on the back surface), particles of a conductive material component penetrate the passivation layer, and are exposed on the surface without being in solid solution in the metal matrix.

Abstract: In a fuel supplying mechanism in which fuel delivery pipes of a non-return type are disposed, the generation region of pulsation resonance is arbitrarily controlled, thereby eliminating various disadvantages otherwise occurring where the pulsation resonance point exists in a favorable rotation region for normal use of the engine. A pair of the fuel delivery pipes 1, 2 of a non-return type is disposed for each bank of a horizontal opposed type or V-type engine and coupled with a connection pipe 4. A characteristic period time of a pulsation wave induced by the pulsation wave generated during fuel injection of the injection nozzles 3 via a connection pipe 4 coupling between one to the other of the fuel delivery pipes 1, 2 is controlled to render the characteristic period time longer to shift the pulsation resonance point out of a low rotation region of the engine as well as to render the characteristic period time shorter to shift the pulsation resonance point out of a high rotation region of the engine.
