  • Publication number: 20100103576
    Abstract: In the case where a battery is reversely connected, unnecessary current-carrying to a glow plug is avoided. Power MOS type field effect transistors 1-1 to 1-n are provided according to a number of glow plugs 5-1 to 5-n to be connected in series between a vehicle battery and the glow plugs 5-1 to 5-n and can be controlled in conduction or non-conduction by a glow-plug control part 51, while a MOS type field effect transistor 2 for protection against reverse connection is provided in series connection between a battery-power joining terminal 3, to which a positive voltage of a vehicle battery is applied, and the ground to cause a reverse current to flow to a fuse 4 through the MOS type field effect transistor 2 at the time of reverse connection of a battery to melt the fuse 4 early whereby current-carrying to the glow plugs 5-1 to 5-n can be avoided.

  • Patent number: 5726564
    Abstract: A temperature-compensating method of a resistance bridge circuit constructed of a plurality of resistance devices, comprises: a first step of adjusting in direction and in curvature a temperature characteristic curve of an output signal issued from the resistance bridge circuit in which a resistor for temperature compensation is connected in parallel with one of a pair of the resistance devices, the pair being disposed in adjacent arms of the resistance bridge circuit; and a second step of applying an additional signal to the output signal of the resistance bridge circuit so as to offset the temperature variation of the output signal of the resistance bridge circuit.
