    • A power supply control device for on-vehicle electric loads is proposed, the control device being capable of detecting breakages at a plurality of electrical loads, a positive side wiring thereof, a negative side wiring thereof, and a commutation circuit. Energization of electrical loads from driving power supply is controlled using switching elements. Anode terminals of commutation diodes connected in parallel with the electrical loads are connected to a load ground by an external common negative line or external individual negative lines. A breakage abnormality at the external common negative line or external individual negative lines is detected by negative line breakage abnormality detection circuit. Load currents at the electrical loads are detected by current detection resistors and current detecting differential amplifier circuits, and it is determined that there is an individual abnormality when a detected current is greatly different from a target current.

    • In an automotive engine control apparatus used for a multi-cylinder engine where both an injection coil and an ignition coil are employed with each of multiple cylinders, abnormal states are systematically detected, while an injection system is mutually interconnected with an ignition system as to these abnormal states. The injection coils are driven via a first switch element by a microprocessor, and injection operations of these injection coils are monitored by a first detection circuit. The ignition primary coils are driven via a second switch element by the microprocessor, and ignition operations of these ignition coils are monitored by a second detection circuit. The microprocessor controls drive stopping means to perform a turn-out drive operation such that this drive stopping means stops both a fuel injection operation and an ignition operation of an abnormal-operated cylinder with respect to an abnormal state occurred in either the injection system or the ignition system. Also, abnormal-state storage operation by abnormal state storage means separatedly provided for the injection system/ignition system/cylinder system, which is derived from stopping of the drive operations, is prohibited by storage prohibiting means.

    • An electrical load is supplied with power from a driving power source, and a microprocessor (CPU) controls the opening/closing current supply rate (duty factor) of an opening/closing element in accordance with target current and driving power source voltage so that open loop control is carried out to achieve predetermined target current. The voltage between both the ends of a current detecting resistor connected to the ground side of the opening/closing element is input as a monitoring voltage from a current detecting amplifying circuit portion through a multichannel AD converter to CPU. When the error between the comparison target voltage corresponding to the target current and the monitoring voltage is above a first permissible error, CPU judges that there is an abnormality sign, and if the error is above a larger second permissible error, CPU judges that there is appearing abnormality. Accordingly, an abnormality sign of a semi-wire-breaking/semi-short-circuit state of the electrical load can be sensed, and abnormality notification can be carried out.

    • The present invention relates to the genetic engineering of higher plants to confer chilling resistance. Provided is a higher plant which contains more unsaturated fatty acids in membrane lipids than are inherent to that plant species, and a process for producing the same. A preferred embodiment of such plant is a transgenic plant expressing a polypeptide with a glycerol 3-phosphate acyltransferase activity that has a higher substrate selectivity for oleoyl-(acyl-carrier-protein) (oleoyl-ACP) than for palmitoyl-(acyl-carrier-protein) (palmitoyl-ACP). In another aspect, there are provided higher plants with a lowered critical temperature for chilling injury, and a process to produce the same. A preferred embodiment of such plant is a transgenic plant whose phosphatidylglycerol contains reduced amount of saturated molecular species due to the expression of a polypeptide with a glycerol 3-phosphate acyltransferase activity that has a higher substrate selectivity for oleoyl-ACP than for palmitoyl-ACP.
