摘要： A reinforcing bar binding machine is provided with a device for detecting a power supply voltage during a binding wire twisting step subjected to the heaviest load and comparing the power supply voltage with a predetermined CPU operation voltage, and a control device for driving a motor in a reverse direction when the voltage has dropped below the predetermined CPU operation voltage. The power supply voltage during operation is monitored, and twisting operation is suspended before the voltage drops below the CPU operation voltage, whereby the binding wire twisting mechanism is returned to the initial position. Therefore, it is possible to prevent the binding wire twisting mechanism from being stopped while grasping the binding wire, when the CPU stops.

摘要： A power steering apparatus includes an electric motor, a temperature sensor, and a control unit. The electric motor produces an assist steering effort in a steering system. The temperature sensor measures a temperature of a first portion subject to thermal influence of operation of the electric motor. The control unit determines an estimated temperature of a second portion in accordance with a value of a motor current, the second portion being subject to thermal influence of operation of the electric motor. The control unit determines a first upper limit value in accordance with the measured temperature; determines a second upper limit value in accordance with the estimated temperature; limit the motor current to a smaller one of the first and second upper limit values, when determining that the temperature sensor is normal; limit the motor current to the second upper limit value, when determining that the temperature sensor is abnormal.

摘要： A cordless power tool such as a power staple gun 1 includes a power supply circuit of an electric double layer capacitor 8 and a lithium-ion battery 11. In a standby state, the lithium-ion battery charges the electric double layer capacitor, and at a switch on time, the electric double layer capacitor supplies large current to the motor 5. By combining the lithium-ion battery with high energy density and the electric double layer capacitor capable of discharging large current, it is possible to greatly reduce the size and weight as compared with a case where a nickel-cadmium battery or a nickel-hydrogen battery is used. Besides, since the electric double layer capacitor has a very long lifetime, the running cost can also be reduced.
