Abstract: The invention provides a transfer printing film, an ink layer of which comprises a urethane resin having a predetermined hydroxyl value and a polyester resin and/or an epoxy resin having an another predetermined hydroxyl value, and provides a golf ball marked by the film. The hydroxyl-functional urethane resin and polyester resin and/or epoxy resin in the ink layer react with isocyanate functional resins in the urethane clear top coat of a golf ball to form urethane bondings respectively, whereby the strong adhesion between the urethane clear top coat and the ink layer is realised, and the transferred pattern becomes to be hardly removed from the golf ball surface and to be superior in hitting durability.

Abstract: A power steering device for steering an outboard engine on a small boat has a hydraulic cylinder unit for angularly moving a steering arm of the outboard engine, the hydraulic cylinder unit having a piston rod connected to the steering arm, and a directional control spool valve for supplying a hydraulic pressure to the hydraulic cylinder unit to move the piston rod. A control cable controls the directional control spool valve in response to operation of a steering wheel. The control cable has a core having an end coupled to the piston rod and a sheath covering the core and having an end coupled to the spool of the directional control spool valve. The hydraulic cylinder unit has a cylinder divided by a piston into a first oil chamber through which the piston rod extends and a second oil chamber remote from the piston rod.

Abstract: Tilt and trim cylinders have blind-end chambers connected through a main valve to a first port of a reversible pump. The rod-end chamber of the tilt cylinder is connected through the main valve to a second port of the reversible pump. The rod-end chamber of the trim cylinder is connected to an oil tank. The second port of the pump is connected to the oil tank, and the first port may be connected to either only the main valve or the oil tank through a suction-prevention valve, an orifice, or a pressure relief valve. When the pump is actuated with the tilt cylinder locked to keep an outboard engine in an tilted-up position, the trim cylinder is automatically contracted to withdraw its piston rod. Cavitation in an oil passage from the blind-end chamber of the trim cylinder to the pump is prevented when working oil is introduced from the oil tank to the pump through the orifice or the pressure relief valve.
