摘要： A motor control device includes a motor, a control portion controlling the motor, estimating a heating temperature of the motor on the basis of an electric current value and an energizing time period or a stopping time period of the motor, and restricting an electrification of the motor in a case where the estimated heating temperature becomes equal to or greater than a limit value, and a temperature sensing device for detecting a temperature of a predetermined portion of a vehicle, wherein the control portion estimates an initial temperature of the motor when an engine is started on the basis of a temperature signal outputted from the temperature sensing device and determines the limit value on the basis of the estimated initial temperature.

摘要： A combustion gas powered fastener driving tool includes inlet and outlet openings through which the combustion gases are discharged from a combustion chamber. These openings are located above the uppermost driving position (top dead center) of a slidable piston, so that an air and fuel mixture is fully trapped in the combustion chamber until after it is combusted. Since an outflow of the unburnt air and fuel mixture is completely prevented, the rate of fuel consumption of the fastener driving tool is high and there is no danger of accidental explosion of unburned fuel even when the fastener driving tool is used in a badly ventilated working place or site. An electric fan for forcing fresh air into the combustion chamber is disposed outside the cylinder and isolated from high temperatures. The fan is durable in structure and reliable in operation.

摘要： In an internal-combustion piston driving apparatus comprising a housing, a cylinder cover fixed to the housing, a cylinder slidably provided to the housing, a piston reciprocally slidably provided in the cylinder, a combustion chamber defined by the housing, the cylinder, and the piston, a fuel supplying device for supplying fuel to the combustion chamber, and an ignition control device for producing a high voltage to ignite the fuel supplied to the combustion chamber, piston position detector for detecting a position of the piston is provided at the wall of the cylinder between top dead point and bottom dead point of the piston. Besides, a decompression channel is provided so as to connect the combustion chamber placed upper than the top dead point with atmosphere for exhausting a combusted gas in the combustion chamber when the piston passes the piston position detector. The decompression channel is opened and closed by means of slide of the cylinder. In addition, a suction valve is provided to the cylinder cover to be placed lower than bottom dead point of the piston whereby the piston is returned by means of atmospheric pressure after a power stroke of said piston.

摘要： A housing partially defines a combustion chamber. A movable piston partially defines the combustion chamber. An air and fuel mixture is generated in the combustion chamber. The air and fuel mixture is ignited in the combustion chamber. An obstacle member is fixedly disposed in the combustion chamber. The obstacle member serves to generate turbulence in an unburned portion of the air and fuel mixture after the air and fuel mixture is ignited. Fuel may be injected into at least two points in the combustion chamber.

摘要： A combustion gas powered tool includes a member defining a part of cylindrical combustion chamber having an axis. A piston is movable in a direction along the axis of the combustion chamber. The piston defines the combustion chamber in conjunction with the member. A mixture of air and fuel is generated in the combustion chamber. The air-fuel mixture in the combustion chamber is burned to drive the piston. An orifice grille extends in the combustion chamber, and is parallel to the axis of the combustion chamber.
