Title: Corona discharger of electrophotographic copying machine
Inventor: TAKAYANAGI HIROSHI
IPC: G03G21/00
Filed: 1982-02-08
Abstract: PURPOSE:To prevent the generation of an erroneous detection result due to a leakage current of a corotron power source transformer by covering the transformer with a conductive case and connecting it to a transformer output low- voltage side in an electrophotographic device which detects the output current of the transformer and then controls image formation conditions. CONSTITUTION:The value of a current flowing between the conductive supporting layer 31 of a photosensitive drum 30 and the shield member 22 of a corotron 20 is found from the output value of an amplifier 50 in the form of a voltage drop across a resistance R. On the basis of the value, a power source 11 for the primary winding of the transformer 10 for powering up the corotron 20 controls the amount of charging. A leakage current from the secondary winding of the transformer 10 flows to the conductive case 13 surrounding the transformer 10 and does not flow through the resistance R because the case is connected to not the earth terminal GF, but the other terminal of the resistance R. Therefore, the leakage current is not contained in the output of the amplifier 50, so no influence upon a measured value is exerted.

IPC: B60H1/32
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To accurately detect the total flow rate of a heat exchanging medium and prevent burn-out of a compressor by detecting the pressure of the heat exchanging medium discharged from the compressor and stopping compressor operation when the total flow rate of the heat exchanging medium has been judged as insufficient based on the detected pressure level. SOLUTION: With automotive air conditioning devices, prolonged use causes a gradual decrease in the total flow rate of the heat-exchanging medium flowing within a heat-exchanging medium channel a. When the flow rate of the heat- exchanging medium falls below a prescribed value, a sufficient amount of the heat-exchanging medium does not flow into a compressor 13, and may cause burn-out thereof. Therefore, a pressure detection sensor 20 to detect the pressure of the heat-exchanging medium discharged from the compressor 13 is provided.  A control device 31 judges whether or not the total flow rate of the heat- exchanging medium has fallen to a value insufficient for driving of the compressor 13 based on the pressure value detected by the pressure detection sensor 20, and stops the compressor 13 to prevent its burn-out when the total flow rate of the heat-exchanging medium has been judged as insufficient.
