摘要： A hand-held machine such as a cleaver or cutter having an engine as the driving source and wherein the drive shaft pipe is formed by telescopically extendable pipe members provided with a fixing means for fixing the pipe members relative to each other. The rotational force of the engine is transmitted to the cutter member via a first drive shaft having a circular section, at least one-way clutch and a second drive shaft on the side of the cutter member, to thereby minimize the size of the device for convenient transportation/storage, to improve the work efficiency, and to secure the safety of the operator.

摘要： An engine blower with excellent engine cooling capacity and sufficient efficiency in restraining noises without deteriorating the blower performance is offered. A fan provided with vanes to create the wind for the blower and the wind for cooling the engine on both side of the rotating plate is rotated inside the blower case in order to cool the engine, the air in the engine case provided with an air inlet port is suctioned into the blower case from the inlet provided on the wall separating the engine case and the blower case by utilizing the negative pressure created by rotation of the fan, the cylinder inside the engine case is cooled by the air passing from the air inlet port to the blower case via the engine case, and the engine noise emitted to the outside from the air inlet port from the engine case is minimized by passing the air in the engine case to the blower case from the air inlet port.

摘要： An outboard engine with an automatic clutch to be used for a fishing boat arranged between the crankshaft of the engine and the propeller driving shaft. The automatic clutch comprises a main centrifugal clutch mechanism which is to be engaged at a revolutional torque close to the rated revolution of the engine and an auxiliary centrifugal clutch mechanism which transmits the torque between the shafts with a frictional slip at a revolutional torque which is produced at a rate lower than the above mentioned one. For operating at a higher speed, the propeller is driven by the transmitted revolutional torque through the said main centrifugal clutch mechanism while for sailing at a slower speed or at trolling, it is driven by the torque which is reduced in transmission by the slip effect in the auxiliary centrifugal clutch mechanism.
