  • Patent number: 6672917
    Abstract: A process for forming an improved anodizing film on the surface of an aluminum alloy material. The film is impregnated with an amorphous substance which fills pores formed in the film during its growth. If the film has a flaw reaching the aluminum alloy material, the amorphous substance and aluminum form a layer of passivity which restrains the corrosion of the aluminum alloy material.

  • Patent number: 6602100
    Abstract: An outboard engine system includes a case member which is disposed below an engine body and integrally provided with an oil pan opening upwards, and a passage wall extending vertically to define an exhaust gas passage through which an exhaust gas flows. A portion of an outer wall of the case member is formed by the passage wall, and a recess is provided in the outer wall of the case member with a portion of the passage wall facing the recess. The recess is covered with a plate member fixed to the outer wall of the case member, and a cooling water passage, through which cooling water flows, is defined between the plate member and the recess. Thus, the passage wall integral with the oil pan is cooled effectively, while avoiding increases in size and weight.

  • Patent number: 6358108
    Abstract: An outboard motor includes a first case and a second case disposed below the first case. The first case houses therein an oil pan and an upper part of a drive shaft. Within the oil pan, engine oil is held. The second case has its upper edge portion coupled to a lower edge portion of the first case. The second case has a vertical wall disposed therewithin. The vertical wall separates a space within the second case into a cavity and part of an exhaust passage through which exhaust gas passes. The cavity is formed below the oil pan. This arrangement prevents the oil pan from being affected by heat of the exhaust gas. Thus, it becomes possible to prevent the engine oil held within the oil from increasing in temperature.

  • Patent number: 6355213
    Abstract: A novel aluminum die-cast material having all good properties of high fluidity, good corrosion resistance and high mechanical strength is disclosed. As its Mg content, a factor to increase mechanical strength, is increased to fall between 0.4 and 0.6% by weight, the material has good mechanical properties. As its Cu content, a factor to cause corrosion, is reduced to at most 0.15% by weight, the material has good corrosion resistance to seawater. As its Si content, a factor to increase casting fluidity, is increased to fall between 10.0 and 11.5% by weight, the material has good fluidity.

  • Patent number: 6333747
    Abstract: An image synthesizing system is provided which can output a high-quality image in real time through the texture mapping without preventing the hardware from being increased in speed and reduced in scale. A 3-D image is formed by a game space processing unit (13) and image supply unit (10) to perform a 3-D computation. At a processor unit (30), coordinates for each dot in a polygon and the corresponding texture coordinates are determined. A field buffer unit (40) stores the texture coordinates at an address specified by the coordinates for each dot. A texture data storage unit (42) has stored a rendering data. The texture coordinates are read out from the field buffer unit (40) and then used to read out the rendering data from the texture coordinate storage unit (42) to synthesize and output a pseudo 3-D image. By thus storing the texture coordinates in the field buffer unit (40), the subsampling/interpolation and the like may be carried out.

  • Patent number: 6312821
    Abstract: The coating structure having a corrosion resistance of the invention contains a formation film formed on the surface of an aluminum alloy material. The formation film is subjected to a zirconium phosphate treatment. Because the zirconium phosphate reacts with an oxide film on the surface of the aluminum alloy to form a zirconium boehmite layer and to increase the adhesion of the coating material, a corrosion resisting structure is obtained without need of a sealing treatment while restraining the increase of the product cost. Also, a primer layer is formed on the outer surface of the formation film and the primer layer is composed of phosphomolybdic acid.

  • Patent number: 6173487
    Abstract: A fan speed controller of an automotive vehicle air conditioning device is usually placed in an air flow duct to be effectively cooled. Thus, compact construction of the speed controller is needed to obtain a larger air flow in the air flow duct. For this purpose, various compact resistor units for the speed controller have been proposed. However, some of them are poor in durability against shocks. In view of this, a compact resistor unit for a speed controller includes a resistor block that has a flat resistor, a flat insulating plate and a flat radiation plate which are respectively positioned against one another. The compact resistor unit further includes a holder block of molded plastic on which the resistor block is mounted. The compact resistor unit also includes a plurality of metal terminals partially embedded in the holder block, where the terminals are connected to particular portions of the flat resistor.

  • Patent number: 6146222
    Abstract: In an outboard engine, a support member for supporting a drive shaft and an exhaust pipe within an extension case can be cooled by outside water pumped by utilizing the exhaust pressure from the engine. The inside of the extension case is divided, by the support member for supporting the drive shaft and the exhaust pipe, into an upper chamber communicating with the open air, and a lower chamber into which outside water is introduced, so that the exhaust gas from the exhaust pipe is discharged into the lower chamber. Both the upper and lower chambers are in communication with each other through a communication pipe. Thus, during operation of the engine, the support member and the depending members are cooled by the outside water forced up from the lower chamber through the communication pipe into the upper chamber.
