Title: Automatic anti-dewing device of drums
Inventor: TANEMO SHINICHI
IPC: G11B15/60
Filed: 1977-10-29
Abstract: PURPOSE: To cut off power supply to the heater of a VTR drum other than when power source is OFF and dewing is liable to occur and when power source is ON and dewing has occured by limiting the power supply to the heater with two sets of switches and a dew detection circuit.  
     CONSTITUTION: Where a switch 8 is held connected to a contact 7c and no power source is applied to a VTR, a switch 8 opens to cut off power supply to a heater 9 when the temperature of the heater 9 is raised above the specified temperature by the power supply through the switch 8. Where power source is OFF, the heater 9 is energized only under the conditions where dewing is likely to occur. In the case when the power source of the VTR is turned ON by connecting the switch 7 to the contact 7b, the heater 9 is energized on condition of dewing by the control circuit through the transistors 12, 10 which conduct when dewing of the drum of the VTR is detected with a dew detection circuit 14 and only when these necessary conditions  are satisfied, the heater 9 is energized, whereby wasteful power consumption, the  occurrence of overheating of the drum, etc. are prevented.

Title: Constant current circuit
Inventor: FURUYA HISAHIRO
IPC: G05F1/56
Filed: 1978-10-27
Abstract: PURPOSE: To ensure a high accuracy for the constant current circuit with a simple constitution by using the FET as the load current control element.  
     CONSTITUTION: FET11 is used, and load 1 and load detection resistance 2 are connected to drain D and source S of FET11 each to form a load circuit. At the same time, the voltage is applied to detection amplifier 4 from reference voltage 3 and resistance 2, and the voltage difference is amplified 4 to be applied to gate G of FET11. Thus the drain current of FET11, i.e., load current I is controlled to the high-accuracy constant current. In this case, the gate current is very small in comparison with the drain and source current for FET11 owing to the element characteristics, and as a result the constant current circuit featuring the accuracy of about 1×10 -3 W1×10 -6  can be easily obtained. Furthermore, as load 1 is connected to the power source side, no overcurrent flows to FET11 even with the ground fault of the load. Thus the special overcurrent control element can be omitted.
