The present invention relates to a four-stroke cycle internal combustion engine in which lubrication oil is atomized to generate oil mist so as to lubricate an internal mechanism of the engine with the oil mist. The magnetic sheet composition contains: a binder; magnetic powder; and a curing agent, wherein the binder contains a thermosetting organic resin, and the curing agent contains a sulfonium borate complex expressed by General Formula 1:where R1 is an aralkyl group, R2 is a lower alkyl group, X is a halogen atom, and n is an integer of 0 to 3. Each provider is associated with a resource and acts as the manager for the resource when interfacing with the resource manager. The metal protective section includes a perimeter and an extension attached to the perimeter and shape to be removably engaged to the grooved opening in the frame. The second data aligner re-aligns the alignment data in synchronization with the input strobe signal to generate internal data. The transport assisting member includes a first part extending along an inner wall of the hollow guiding path from a discharge port of the recovery chamber to a position for contact with the transport unit, and a second part intersecting with a front surface of the first part and extending from an intermediate position of the first part to a position for contact with the transport unit.
