摘要： PURPOSE:To reduce reverberation sound generated by vibration of a circuit vessel by an inexpensive structure. CONSTITUTION:Insulating resin films 60 for protecting a circuit and preventing a sort-circuit are stuck to inner surfaces of covers 20, 30 of a circuit vessel 1 containing an electronic controller for a vehicle with double-adhesive tapes 51, 52, 53. The tapes 52 are provided along diagonal directions of the covers 20, 30. A frequency of a vibration wave generated at the time of transmitting a vibration to the vessel or at the time of hitting the vessel is varied at the tape 52 as a boundary. Thus, the vibration wave as an entire cover is reduced, and easily attenuated, thereby reducing reverberation sound.

摘要： PURPOSE:To simplify a signal output line and make a device compact and silent without harming pump stopping function at the engine stop time. CONSTITUTION:There is provided a computer 5 for transmitting an off-signal of the same electric potential as the electric potential of a body 7 to a signal output line 9 at the engine stop time and transmitting a driving signal of larger in electric potential than the off-signal to the signal output line 9 at the engine operating time. There is also provided an FET 12 series-connected to the power supply line 8 of a fuel pump 4 so as to switch the terminal voltage of the fuel pump 4 to the voltage corresponding to the inputted driving signal at the time of inputting the driving signal and to stop the fuel pump 4 at the time of inputting the voltage corresponding to the off-signal. The fuel pump 4 is thereby stopped positively even if the power supply line 8 and the signal output line 9 have earth potential, and the simplification of the signal output line 9 and the compactness and serenity of a fuel pump control device 1 are attained without harming safety.

摘要： PURPOSE:To provide a load drive device which can easily sense overheating of a switching means like a power transistor. CONSTITUTION:A load driving device comprises a power MOSFET 1 for motor current control, a PCT thermistor 2 whose resistance value increase when temperature rises, resistors 3, 4, a capacitor 5 for preventing oscillation, an ALM board 9, and heat dissipating fins 10. The PCT thermistor 2 can quickly detect heat generation of the power MOSFET 1 by the effect of the ALM board excellent in thermal conductivity. Thereby thermal protection is enabled more quickly.

摘要： PURPOSE:To reduce the dimension of a semiconductor switching element and reduce cost by cooling the element by the air flowing through an air flow passage. CONSTITUTION:A filter 5 for collecting particulates is installed in the exhaust system of a diesel engine 1. An electric heater 6 is installed at the upstream side end part of the filter 5. A motor-driven air pump 9 supplies the secondary air to the filter 5. Midway in the electric power source circuit of the electric heater 6, a bipolar transistor 12 is arranged. Midway in the electric power source circuit of the motor-driven type air pump 9, a bipolar type transistor 13 is arranged. An ECU 16 controls the transistor 12, and puts the electric heater 6 into an electric conduction state, and controls the transistor 13, and drives the motor-driven type air pump 9. In this case, the transistors 12 and 13 are arranged in the air flow passage of the motor-driven type air pump 9, and the transistors 12 and 13 are cooled by the air which passes through the air flow passages.

摘要： PURPOSE:To provide a load driving circuit equipped with a diagnostic function which can eliminate the port of a diagnostic control circuit. CONSTITUTION:At a control signal generating circuit 13, (a) output is set at 'L' corresponding with the turning on of an air conditioning switch 11, and a load 12 is operated by setting a terminal 131 at 'H' and turning on an MON transistor 16 of a diagnosis control circuit 15. When an overcurrent flows to the MOS transistor 16, an MOS transistor 19 for detection is turned on by an overcurrent detection circuit 18, and the terminal 131 is set at 'L', and at the same time, the MOS 16 for control is turned off. At this point, since the electric current is lowered, an output from the overcurrent detection circuit 18 becomes 'L', the MOS transistor 16 is turned on, and an overcurrent flows again, and an overload is detected, and an oscillating motion takes place. This oscillating motion appears on the terminal 131, and is monitored as a monitor output, and by the oscillation of the monitor output, the overcurrent of the MOS transistor 16 is judged, and the (a) output is fixed at 'H'.
