摘要： PROBLEM TO BE SOLVED: To provide a cylinder device capable of freely transmitting force not only in the direction of traveling straight to the axis of a cylinder tube but also in all directions.
SOLUTION: The cylinder device comprises the cylinder tube, a piston slidably incorporated in the cylinder tube, a piston rod having one end fixed to the piston and the other end protruded from an opening portion at the end of the cylinder tube, and a tube connected to the end of the cylinder tube from which the piston rod is protruded, so that the piston rod is slidable inside. The flexible and strong piston rod is such that a metal rod body is arranged inside a hollow portion of a resin cylindrical body into one unit. The tube connected thereto to cover the piston rod is freely direction-deformable while maintaining a certain shape.

摘要： PROBLEM TO BE SOLVED: To prevent degradation of the property of a thermal-sprayed film by avoiding inclusion of non-molten particles in the thermal-sprayed film. SOLUTION: A gas wire-melting type thermal spraying gun 21 receives a wire 23 formed of a ferrous material as a thermal spraying material fed from a wire feeder 25, and receives the fuel gas and oxygen fed from a fuel gas cylinder 27 and an oxygen cylinder 29, respectively. The thermal spraying gun 21 blows a combustion flame 35 from a thermal spraying nozzle 21a while rotating and descending inside a cylinder bore and preheats a bore inner surface 19a. In this condition, no wire 23 is fed from the wire feeder 25. When the thermal spraying gun 21 is elevated while rotating, the wire 23 is fed from the wire feeder 25, and the wire 23 is melted by the combustion flame 35. Molten particles 37 are blown out of the thermal spraying nozzle 21a to form a thermal-sprayed film 39 on the bore inner surface 19a. The thermal spraying nozzle 21a is directed backwardly in the moving direction of the thermal spraying gun 21. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a power-saving engine and the engine. SOLUTION: This power-saving engine comprises an engine seat, a cylinder, valves, a spark plug, a piston, a piston connecting rod, a crank, and a power- saving device. The power-saving device comprises a first power-saving connecting rod and a second power-saving connecting rod. One end of the first power-saving connecting rod is connected to the engine seat, and the other end is connected to the connecting rod of the cylinder piston. The second power- saving connecting rod is connected to the proper position of the first power- saving connecting rod, and the opposite end of the connection end of the second power-saving connecting rod with the first power-saving connecting rod is connected to the crank. By the installation of the first and second power-saving connecting rods, the action of a lever is produced by the transmission of a power from the piston connecting rod to the crank, and the effect of power saving of an engine output can be achieved.

摘要： PROBLEM TO BE SOLVED: To hold the sliding surfaces of a piston rod and sealing member in between in an always lubricated condition even in case a nitride film and oxide film are formed on the periphery of the piston rod. SOLUTION: The outside surface of a metal member 5 as a base for a piston rod 4 is subjected to a grinding process with a surface roughness of approx. 0.1-0.2 μm so that a number of dints are formed. On this outside surface of metal member 5, a nitride film 6 is formed, and thereon an oxide film 7 is formed. The surface of this oxide film 7 is subjected to a buff polishing process so that a number of micro-crators 7A are formed in positions mating with the dints in the metal member 5.
