  • Patent number: 9162564
    Abstract: A fuel tank comprises an upper-half tank body (7) and a lower-half tank body (8) which are made of bowl-shaped steel plates and which integrally include a flange (7f) and a flange (8f) in their peripheral edges, respectively, the flanges (7f, 8f) being superposed on and liquid-tightly connected to each other. The flanges (7f, 8f) are connected together by crimping into a roll shape to form an annular thick-walled connection (12), and an annular reinforcing rib (7r, 8r) leading to the connection (12) is formed at least in one of the upper-half and lower-half tank bodies (7, 8). Thus, it is possible to provide a fuel tank in which a sufficient strength can be imparted to portions around a flange connection, without particularly increasing the thickness of a steel plate.

  • Patent number: 7974555
    Abstract: A development apparatus 8 has developer transport members 26 and 27 respectively contained in containers 22 and 23 and transporting developer while stirring the developer and passing the developer to each other at a passing portion 41 and a passing portion 42, thereby causing the developer to circulate in a developer tank 21. The passing portion 41 is formed at a location of a partition 21c adjacent to a developer discharging mechanism 34 and the passing portion 42 is formed at a location of the partition 21c away from the developer discharging mechanism 34. The passing portions 41 and 42 have configurations in which a transport force acting on the developer at the passing portion 41 is greater than the transport force acting on the developer at the passing portion 42.

  • Patent number: 7779792
    Abstract: An air-cooled engine (10) has a fan cover (16) for covering a cooling fan (14). The cover (16) is composed of a fan-cover peripheral wall (44) for covering the outside of the cooling fan (14), and a top board (45) for closing off one end of the fan-cover peripheral wall (44). The fan-cover peripheral wall (44) has an internally disposed guiding duct (47) for guiding cooling air (Wi) from the cooling fan (14) to an engine main body (12). A first fastening member (42) secures a portion of the external part of the fan-cover peripheral wall (44) that is proximal to the guiding duct (47) to a casing (25) of the engine main body (12). A second fastening member (41) extends from the casing (25) and through the fan-cover peripheral wall (44), and secures a top board (45) in a portion that is at a distance from the guiding duct (47).

  • Patent number: 7693405
    Abstract: An image pickup device is provided which includes: an auto focus control unit sampling contrast values as a function of a relative distance from an object by detecting a contrast of an image of the object while driving a lens in an optical axis direction, calculating a focused focal position on the basis of the contrast values, and driving the lens to the focused focal position; a shake detecting unit detecting at least an amount of shake in the optical axis direction of the lens; and a selection judging unit judging selection and non-selection of the sampled contrast values depending on the amount of shake in the optical axis direction of the lens at the time of the sampling. Here, the auto focus control unit calculates the focused focal position on the basis of the contrast value judged as being selected by the selection judging unit among the sampled contrast values.
