摘要： Provided is a voltage regulator capable of setting an accurate short-circuit current. Used as a circuit for determining a current value of a short-circuit current of an overcurrent protection circuit is not a resistor for converting current into voltage but a circuit for controlling in the form of current, that is, a circuit of an N-channel depletion type transistor including a gate and a drain that are connected to each other and operating in a non-saturated state. The N-channel depletion type transistor has process fluctuations that are linked with those of a detection transistor, and hence an accurate short-circuit current may be set without trimming.

摘要： Provided is a voltage regulator capable of reducing fluctuation of an output current even when an output terminal thereof is short-circuited. In a case where the output terminal of the voltage regulator is short-circuited, an output current (Iout) of the voltage regulator is limited and fixed to a limit current value. When an output voltage (Vout) of the voltage regulator decreases to have a value equal to or smaller than not a detection voltage value (Vref3) of a reference voltage circuit (34) but a detection voltage value (Vref2) of a reference voltage circuit (31), a second limit operation in which the output voltage (Iout) is further limited to be decreased is set. Further, in a case where the output terminal is short-circuited and then reset, when the output voltage (Vout) has a value equal to or larger than not the detection voltage value (Vref2) but the detection voltage value (Vref3), the second limit operation is canceled.

摘要： Provided is a DC-DC converter including a short-circuit protection circuit which can stably perform a reset operation and a stop operation. The short-circuit protection circuit includes a detection circuit, a delay circuit, and a latch circuit. The delay circuit is reset in response to an output voltage abnormality signal related to a switching regulator which is outputted from the latch circuit. The latch circuit is reset based on an AND operation between the output voltage abnormality signal and a UVLO signal.

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.
