Abstract: An outboard motor includes an improved arrangement for an exhaust system, in association with a lubricant tank and a cooling system, for a four-cycle internal combustion engine that powers the outboard motor. The cooling system discharges coolant independent of an exhaust pipe and an expansion chamber of the exhaust system so as to inhibit an influx of coolant into the engine should the engine become temporarily disabled. In addition, the cooling system provides a pool or bath of coolant between the exhaust pipe and the lubricant tank to inhibit excessive heating of these components during normal and abnormal running conditions (i.e., if the engine becomes disabled).

Abstract: A recording sheet includes a micro-capsule layer which includes a plurality types of micro-capsules colored with different colors, for example, primary or complimentary colors of a subtractive mixture. The micro-capsules are filled with core materials which are discharged when the micro-capsules are broken. Each type of micro-capsule is selectively broken by a selective temperature and pressure application. When a micro-capsule is broken, the core material blends out the color of the micro-capsule. Additionally, an image forming system includes a heating unit for selectively heating the micro-capsules by an output of a Joule heat or light irradiation. Different wavelengths of light are radiated by the light irradiation heating unit, which are absorbed depending upon an absorption band exhibited by the different colored micro-capsules.
