    摘要: A power supply circuit that withstands voltages greater than or equal to a voltage capacity and prevents an increase in circuit area and manufacturing costs. The power supply circuit includes a first transistor for receiving a DC voltage and generating an internal power supply voltage. A clamp circuit is connected to the first transistor. The clamp circuit is activated when the DC current voltage is an excessive voltage to clamp the internal power supply voltage at a predetermined voltage that is less than the excessive voltage. A gate voltage control circuit is connected to the first transistor and the clamp circuit to supply the gate of the transistor with a control voltage so that the internal power supply voltage decreases when the clamp circuit is activated.

    摘要: A DC-DC converter includes first and second capacitors coupled in parallel, a switching part for controlling the first and second capacitors so that the first capacitor is charged by an input voltage and the second capacitor is charged by a discharging of the first capacitor, an output voltage being obtained at one end of the second capacitor, and the switching part including a discharge path through which the second capacitor is discharged. An output voltage detection units detects the output voltage and determines whether or not the output voltage satisfies a predetermined condition. A discharge path breaking units breakes the discharge path when the output voltage detection unit determines that the output voltage satisfies the predetermined condition, so that the first capacitor is prevented from being discharged through discharge path.

    摘要: An apparatus includes first and second processors, a common memory, and a switch. The first processor executes an operating system, connects to a communication network and communicates with the communication network. The second processor operates independently of the operating system, connects to the communication network, and communicates with the communication network. The second processor writes, in the common memory, communication setting information being used by the second processor when the switch switches the connection destination from the second processor to the first processor. The first processor acquires the communication setting information, and sets the acquired communication setting information to the first processor. The switch switches the connection destination of the communication network from the second processor to the first processor after the communication setting information has been set to the first processor.
