Filed: 1992-05-15
Abstract: PURPOSE:To correctly detect abnormalities of a crank angle detector to be used for controlling the fuel injection and the ignition timing of an internal combustion engine. CONSTITUTION:A processing circuit 6 reads the voltage +B of a battery 3 which gradually starts after an ignition key switch 2 is conducted with the ON contact through an analog/digital converter 8, and when the circuit detects that the voltage +B drops to or below the voltage V2 after the voltage +B once reaches or exceeds the voltage V1, and a starter motor 10 is rotated by a start detecting circuit 7, a judgement is made that the starter motor is securely rotated and a judgement of abnormalities of a crank angle detector 15 is made. On the other hand, when the starter motor driving is detected before the conduct with the ON contact of the ignition key switch 2 to start the voltage +B, a judgement is made that the starter motor 10 and the relevant components are in abnormal condition, and the abnormality judgement of the crank angle detector 15 is prohibited.

IPC: H02J1/00
Filed: 1993-04-28
Abstract: PURPOSE:To eliminate erroneous function due to mechanical impact or fluctuation in the error voltage component by providing a circuit including an output switching element, a parallel resistor, a resistor in the series circuit of a semiconductor switch, and a voltage control signal take out point at the joint of the semiconductor switch. CONSTITUTION:When semiconductor switches 3, 4 are conducted by an output switching control circuit 6, current is fed from a DC power supply 1 through two paths to a positive output terminal 7 and a load 9. One current path passes through a semiconductor switch 4 whereas the other current path passes through a resistor 2 and a semiconductor switch 3. The former can pass more current than the latter and an error voltage is produced due to the conduction resistance of the switch 3 and the line resistance up to the terminal 7. In the case of the latter, output voltage from the terminal 7 is fed back, as a control signal, to the power supply 1 and stabilized regardless of the error voltage in the current path of the switch 4 by making the resistance of the resistor 2 larger than the conduction resistance of the switch 3.

Since the L-shaped metallic ring 5 is used as a current collecting body as mentioned above, the wide area of the inner wall of the part 6 touching the reducing  surface collects the electric potential of argentous oxide existing in the surface 3, and the wide  area of the outer surface of the part 7 transmits the above electric potential to the case 1.  Consequently, a battery which has a small internal resistance and can produce an operational  voltage of 1.55V, which is the same as that of argentous oxide (Ag2O), is obtained.
