  • Publication number: 20100162974
    Abstract: A water pump attachment structure of a water-cooled internal combustion engine is provided to facilitate the maintenance of a valve train. A water pump attachment structure of a water-cooled internal combustion engine includes a semicircular cut-away surface of a water pump holder opposed to a semicircular surface of a cylinder head to form a water pump support circular hole. Screw members are passed through respective screw through-holes of the cylinder head and threadedly engaged with internal thread holes of the water pump holder. Thus, the water pump holder is fastened to the cylinder head. A water pump is fitted into and secured to the water pump support circular hole. A cylinder head cover is attached to the cylinder head by allowing their mating surfaces to conform with each other with the water pump holder liquid-tightly sandwiched therebetween.

  • Patent number: 7421996
    Abstract: An lubrication device for an engine includes: a crank case which freely rotatably supports a crank shaft and also which stores oil at its lower part; an oil strainer which is so arranged as to be fixed in the crank case; and an oil pump which suctions the oil at the lower part in the crank case via the oil strainer. In the lubricating device, the machining efficiency can be improved by reducing the time of machining to a crank case to thereby decentralize machining processes, and also the oil temperature can be reduced. A crank case cover covering part of a crank case and coupled with the crank case is provided with an oil suction passage which leads to an oil pump, and an oil strainer communicates with the oil suction passage via a connecting pipe which is a member different from the crank case.

  • Patent number: 7194985
    Abstract: An engine cooling structure for a water cooled engine includes water pump and a thermostat. The water pump pumps coolant to a water jacket of the engine. The water pump and thermostat are provided on a cover member installed on an outside of a crankcase of the engine, and a coolant passage, which communicates with the water jacket through the water pump from the thermostat, is integrally formed in the cover member, so as to obtain arrangement of the cooling structure that is efficient in terms of space. The engine cooling structure increases the degree of freedom of layout around a cylinder head by keeping the projection amount on a side of the cylinder head small, simplifies the piping construction, and reduces the number of assembly steps.

  • Patent number: 7085093
    Abstract: A two-step self-servowriting process first writes an intermediate pattern based on a reference pattern, and then writes a final pattern based on the intermediate pattern, wherein the reference pattern can be a printed media or a spiral pattern. Such an approach can be utilized to reduce the noise/runout, eliminate timing eccentricity, and increase the sample rate of the final pattern. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.

  • Patent number: 7061709
    Abstract: A two-step self-servowriting process first writes an intermediate pattern based on a reference pattern, and then writes a final pattern based on the intermediate pattern, wherein the reference pattern can be a printed media pattern. Such an approach can be utilized to reduce the noise/runout, eliminate timing eccentricity, and increase the sample rate of the final pattern. The final pattern should be written as a 3-step-per-track, trimmed (or untrimmed)-burst pattern, while the intermediate pattern can be written as a 1.5-step-per-track, trimmed (or untrimmed)-burst pattern. Since half of the steps servowriting the intermediate pattern can be omitted under such a scenario, approximately half of the servowriting time can be saved. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.

  • Patent number: 7040306
    Abstract: A blowby gas ventilation system for an internal combustion engine capable of preventing oil from being diluted by efficiently and quickly exhausting a blowby gas together with a water content and the like from a crank chamber through forced ventilation of the crank chamber. The blowby gas ventilation system is intended for a four-stroke-cycle internal combustion engine. The system includes a fresh air introduction pipe, through which fresh air is sent from an outside of the internal combustion engine through a throttle portion to a crank chamber. The system also includes a blowby gas return passageway, through which the blowby gas is returned back to a downstream side of an air cleaner.
