20080215628 | Replacement part order processing apparatus, method for ordering replacement parts and computer-readable recording medium - A controlling unit of a replacement part management server specifies a maintenance target equipment and acquires order conditions from a responsible personnel terminal. The controlling unit acquires maintenance information and part information both relating to the maintenance target equipment. The controlling unit calculates prediction residual regarding target parts of an initial value setting process, and compares the prediction residual with the shortest cycle. When the prediction residual is smaller than the shortest cycle, the controlling unit sets the number of replacements in the part order data storing unit. When an initial value setting process regarding all the parts is completed, an order input screen is output. When an order request is received from the responsible personnel terminal, an order management server acquires part order data and transmits a preparation instruction of a PM kit to the purchaser. | 09-04-2008 |

The actuator is attached to a lateral surface positioned opposite the offset direction of the head covers. In an embodiment, the actuator is attached to a lateral surface of the head covers and positioned close to the inside of the V banks. | 09-30-2010 |
20100242872 | FUEL FEEDING DEVICE OF A V-SHAPED ENGINE FOR MOTORCYCLE - A motorcycle mounted with a V-shaped engine in which a front bank and a rear bank are disposed like a V-shape and a fuel pump for fuel injection is mounted. The fuel pump is driven by a camshaft of a cylinder head, and mounted on the upside of the cylinder head. The fuel pump is fitted is the cylinder head of the front bank at the back of a head pipe. A fuel chamber is provided between the fuel pump an the injectors, the fuel chamber is disposed lengthways in the vertical direction in the V-bank space K, and a lower end part is disposed facing the sides of the injectors, and connection to the injectors by fuel pipes extending from the lower end part substantially horizontally. With this configuration, the fuel pump does not obstruct other components in the motorcycle, and is protected without a special cover. | 09-30-2010 |
20100242875 | VALVE GEAR FOR INTERNAL COMBUSTION ENGINES - A valve gear for an internal combustion engine having a sub-rocker arm return spring that is shortened in a longitudinal length of a cylinder. The valve gear for the internal combustion engine is provided with a camshaft, an intake cam turning integrally with the camshaft, a valve cam for opening and closing an engine valve, a link mechanism for transmitting a valve driving force to the valve cam, a holder for supporting a sub-rocker arm support and a driving mechanism for varying a fulcrum position of the link mechanism. A valve operating characteristic can be varied with an oscillating position of the sub-rocker arm support. A sub-rocker arm is provided with a roller, an eccentrically disposed step and a link section. The step is provided with a spring socket, and a return spring is arranged intervening between the spring socket and the holder. | 09-30-2010 |
20100242882 | VALVE MOTION FOR AN INTERNAL COMBUSTION ENGINE - A valve motion for an internal combustion engine which suppresses the height of the internal combustion engine low. In a valve motion for an internal combustion engine, a driving mechanism includes a ball screw disposed over an intake side camshaft and an exhaust side camshaft and having threaded portions provided thereon which are threaded in different directions from each other on the intake side and the exhaust side. Sliders are individually provided on the intake side and exhaust side and movable on the ball screw with connecting link members provided between the sliders and a holder member. | 09-30-2010 |
