Abstract: An injector arrangement structure includes an air cleaner which is arranged at a rear side of an engine for a vehicle, a rear suspension which extends vertically at the rear side of the engine, and a first injector which is attached to the air cleaner. The air cleaner includes an outlet tube configuring a clean side of the air cleaner. The rear suspension and the outlet tube overlap each other in a side view. A partition wall dividing an intake passage vertically is provided inside the outlet tube. The first injector is attached from a lower side of the outlet tube so as to inject fuel toward the partition wall.

Abstract: Provided is a transmission which eliminates torque loss during gear shift and with which the processing of components can be simplified. An axial force is generated in a protrusion by means of a first portion during gear shift from a low gear to a high gear, and when a low-speed transmission gear and a clutch ring separate from each other, a high speed transmission gear and the clutch ring interlock. Since relative movement of the protrusion in a neutral direction is suppressed by means of a first retaining portion during coasting, gear disengagement whereby the transmission gears and the clutch ring separate from each other can be suppressed. Since the first retaining portion can be formed in a first wall when providing a groove portion, an increase in the component processing workload can be suppressed.

The conversion unit generates the converted movement information by correcting the movement of the particle using the distance determined by the distance calculation unit.

Abstract: A display control unit displays, in a case where the display control unit is in a startup state or in an abnormal operation state of a general purpose application, a display window of a dedicated middleware even when a startup of the dedicated middleware is completed and a startup of a general purpose middleware is not completed. With this configuration, the user operation is allowed to perform operation to the general purpose application and is not required to wait until the startup of the general purpose middleware is completed. When the startup of the general purpose middleware is completed, a display window of the general purpose application which includes display window data transferred from the general purpose middleware is displayed. Thus, information related to the general purpose application can be promptly provided to a user.
