To provide a fluid pressure regulation apparatus and a fuel supply apparatus which are compact in arrangement and simple in construction, a pressure regulator includes a housing, a pressure adjustment member constituted by a partition wall forming together with the housing a pressure adjustment member held in communication with a fluid introduction opening and having the pressure adjustment chamber brought into communication with a fluid discharge opening in response to the pressure of fluid in the pressure adjustment chamber. The pressure regulator is capable of adjusting the fluid pressure in the pressure adjustment chamber to a preliminarily set pressure, and has one surface side thereof forming an area of a pressure receiving range receiving the fluid pressure, the area being variably set and the set pressure being varied in response to the area of the pressure receiving range.

There is provided a surface light source device having a configuration where light sources are arranged on both of a pair of side surfaces of a light guide plate and allowed to independently form nonuniform light emission intensity distributions in which light emission intensity is lower and higher at places closer to and farther from each of the light sources. Light guide control sections controlling guiding of light from light sources are arranged on a reflection surface of a light guide plate. The light guide control section is configured of concave sections, and the concave sections include inclined surfaces facing the light source and inclined surfaces facing the light source, respectively, and the heights of the concave sections increase with increasing distance from the light source. A nonuniform light emission intensity distribution in which light emission intensity is lower and higher at places closer to and farther from the light source is formed by lighting of the light source. As the inclined angles of the inclined surfaces are larger than the inclined angles of the inclined surfaces, an influence of the light guide control section on light from the light source is reduced.

An exhaust gas purifying catalyst comprises a substrate having a through hole serving as a passage for exhaust gas; and a catalyst coating layer formed on an internal surface of the through hole. The catalyst coating layer contains: a component (i): a precious metal; and a component (ii): at least one of a Zr oxide, a Ce oxide and a ZrCe mixed oxide. On an upstream portion of the passage, an oxide equivalent weight of Zr is within a range of 51-100 wt % of an oxide equivalent weight of Zr and Ce contained in the component (ii). On a downstream portion of the passage, the component (ii) includes at least one of a Ce oxide and a ZrCe mixed oxide in which an oxide equivalent weight of Ce is within a range of 58-100 wt % of an oxide equivalent weight of Zr and Ce contained in the ZrCe mixed oxide.

A fuel supply device has a main line, a fuel pump, a first return line, a second return line, a valve mechanism, a first pressure regulator, and a second pressure regulator. The fuel pump is arranged in a fuel tank or in the vicinity of the fuel tank, and pressurizes the fuel in the fuel tank and supplies the furl to a fuel distribution pipe via the main line. The first return line returns the fuel from the fuel distribution pipe to the fuel tank. The second return line is branched from the main line in the vicinity of the fuel pump and returns the fuel from the main line to the fuel tank. The valve mechanism selectively connects and disconnects the second return line with respect to the main line. The first pressure regulator is arranged in the first return line. The second pressure regulator is provided in the second return line and adjusts fuel pressure to a lower level than the first pressure regulator does.

A fuel tank apparatus includes a sub-cup having a bottom portion and a side portion erected from said bottom portion and provided in a fuel tank and a suction filter arranged in a space surrounded by the side portion above the bottom portion and connected to a fuel pump. The side portion includes a partition wall partitioning the space into a main chamber in which the suction filter is arranged, and a sub-chamber. Maximum height H1 of the suction filter is higher than the height H2 of the partition wall. Because of such a structure, a fuel tank apparatus can be provided by which the fuel can reliably be supplied even when much water is retained in the tank.
