Abstract: PURPOSE:To control accurately the supply amount of a toner without receiving a change of the volume of exposure light, by attaching the toner to an area where no electrostatic latent image is formed and then measuring the concentration of the toner. CONSTITUTION:A photosensitive drum 1 is charged evenly to -600V by an electrostatic charger 2 and receives a slit exposure at an exposure part. Thus an electrostatic latent image is formed on the drum 1. -450V development bias voltage is applied to the drum 1 when the charged and unexposed part at the tip side (or rear end side) of the part where an electrostatic latent image is formed reaches a development region. Then a toner of about intermediate concentration is adhered to the unexposed part, and the concentration of this toner is detected by a photodetecting element 31 to control the toner concentration. The producing part of the electrostatic latent image is developed by -300V development bias voltage. The same result is obtained by varying the charging voltage in place of the use of the development bias voltage.

Abstract: PURPOSE:To prevent the danger of explosion and the like even if a safety valve should not work by prefoaming in the state of opening an exhaust valve at the time when the pressure in a prefoaming tank reaches the given pressure more than the set pressure of the safety valve. CONSTITUTION:A vapor feeding line 19, a cooled air feeding line 20 and an emergency compressed air feeding line 21 are provided in a vapor chamber 4 and solenoid valves 22, 23 and 24 are installed in the respective lines, and the required series of operations are controlled automatically by a control panel 25.

Abstract: PURPOSE: To easily indicate leakage current of a CMOS integrated circuit when the leakage current is increased by setting the output of a voltage comparator to be applied as one input of a logic circuit to "1" when the input from a voltage amplifier is higher than the reference voltage.  
     CONSTITUTION: The magnitude of a power supply current flowing when the voltage of a power supply 1 is applied to a CMOS integrated circuit 2 is detected at the voltage across a resistor 3. The voltage across the resistor 3 is applied to the input of the voltage amplifier 4, and the output of the amplifier 4 is applied to a voltage comparator 7 with reference voltage variable upon alternation of a battery 5 and a potentiometer 6. The output from the comparator 7 is inputted to a logic circuit 10 together with a pulse delayed through a variable delay unit 9 at the pulse generated from a pulse generator 8 triggered when the voltage across the resistor 3 exceeds predetermined value, and also applied to the ligic circuit 10, which multiplies them. Since the output from the comparator 7 becomes "1" when the input from the amplifier 4 is higher than the reference voltage, when the leakage current exceeds predetermined set value, the indicator circuit 11 indicates "1" to be thus detected.
