摘要： A method for preventing corrosion of a contact, includes comparing a potential of a signal line connected to the contact with a predetermined potential corresponding to the corrosion of the contact; flowing a corrosion-prevention current into the contact when a result of the comparing shows that the contact is corroded; inputting into the signal line a signal used for judging a logical value of a connection state of the contact; and in the magnitude relation, setting the predetermined potential on another side of a threshold level used in the judging of the logical value of the connection state of the contact.

摘要： An overcurrent protection apparatus includes two overcurrent protection circuits. The first overcurrent protection circuit compares an electric potential on the downstream side of a first resistance element with a reference potential produced by a second resistance element by a comparator and determines that overcurrent has been caused and intercepts current flowing through a first series regulator when the electric potential on the downstream side of the first resistance element is lower than the reference potential. When the resistance value of the second resistance element is larger than the resistance value of a fourth resistance element of the second overcurrent protection circuit, e.g., 1.2 times the resistance value of the fourth resistance element, the first overcurrent protection circuit intercepts the current flowing through the first series regulator at a current value of 1.2 times a current at which a downstream second series regulator is intercepted by the second overcurrent protection circuit.

摘要： A circuit for preventing corrosion of a contact, includes an input terminal, a signal line, a switch, an impedance element, and a comparator. The input terminal is to be connected to the contact, which is outside the circuit. The signal line is connected to the input terminal. The switch is connected to the signal line. The impedance element is connected to the signal line in parallel to the switch. An impedance of the switching section is smaller than that of the impedance element. The comparator compares a potential of the signal line with a predetermined potential. The switch is turned on based on a comparison result output from the comparator.

摘要： An apparatus for preventing a contact from being corroded includes a power source, a signal line connected to the contact, a resistance connected to the signal line, a switching section, a comparator, and an overheat detecting section. The switching section has a switch between the power source and the signal line. An impedance of the switch is smaller than that of the resistance when the switch is turned on. The comparator compares a potential of the signal line with a predetermined potential to determine as to whether or not the contact is corroded. The comparator outputs a driving signal when the comparator concludes that the contact is corroded. The overheat detecting section detects whether or not temperature of the apparatus exceeds a predetermined temperature. The overheat detecting section decreases current flowing through the switching section when the temperature of the apparatus exceeds the predetermined temperature.
