  • Patent number: 6264515
    Abstract: An outboard motor with an engine where the exposed ends of the crankshaft and camshaft project downward toward the bottom surface of the engine. An accommodation chamber is recessed within the bottom surface of the engine. A chain driven camshaft drive mechanism fits within this accommodation chamber. An oil pump, mounted below the accommodation chamber, is driven by the crankshaft. The bottom end of the crankshaft is sandwiched between the bottom surface of the engine and an oil seal housing. The oil seal housing fits within a recessed opening in a plate-like engine holder positioned below the engine. A plurality of positioning and fastening bosses are used to align and fix the oil seal housing to the engine. When the engine is removed from the outboard motor, its bottom surface is flat enabling the engine sit upright on a workbench.

  • Patent number: 5772119
    Abstract: A shower head comprises a hot-water treating mechanism accommodated in a water passage formed in a shower head case of the shower head. The hot-water treating mechanism has coral sand and active carbon fiber, and has calcium sulfite if necessary. These materials are arranged serially along a water-flow direction in the shower head. For example, these materials are arranged concentrically, through which hot water is made to flow from the center to the periphery. In order to realize this concentrical arrangement of these materials, these materials are made to be a sheet structure, and are overlaid and wound to form a sheet roll. Acrylic active carbon fiber can be used as the active carbon fiber. The shower head can effectively remove chlorine from a large flow rate of hot water having a temperature of about 40 degrees of centigrade. Further, it is possible to reduce in weight of the shower head having a hot-water treating mechanism below 300 grams.
