  • Patent number: 6956377
    Abstract: A detection part (B), of a disconnection detection apparatus (1A), detects an open destruction of a detection resistor. An emitter of a transistor (Q5) is connected to an upstream end of a detection resistor (R1) through a diode (connected forward) (D2). A base of the transistor (Q5) is connected to a downstream end of the detection resistor (R1) through a resistor (R8). A collector of the transistor (Q5) is connected to an upstream side of a resistor (R4) of a determination part (3). In the detection part (B), the transistor (Q5) is turned on and off according to the difference in the potential between both ends of the detection resistor (R1). In an open destruction detection state, generated when the transistor (Q5) is ON, electric current supplied by the power supply 4 is fed to the determination part (3) through the transistor (Q5) as a detection result indicating that an open destruction has occurred.

  • Patent number: 6097509
    Abstract: An image sensor has a photoelectric conversion unit composed of an array of a plurality of sets of a photoelectric conversion element having one electrode connected to a power source line and a switching element connected to another electrode of the photoelectric conversion element to receive an output thereof. A shift register, operating in synchronism with a clock supplied thereto, generates a pulse to turn on the switching element. The current that the switching element outputs when turned on is stored in and converted into a voltage by a capacitor. When the switching element is turned on, a transistor that forms a discharging path for the capacitor is connected in parallel with the capacitor. This transistor is turned on with a pulse obtained by delaying the clock. Thus, the capacitor is cleared over a period including periods before and after the switching element is turned on.
