IPC: H02H7/20
Filed: 1984-09-14
Abstract: PURPOSE:To minimize number of circuit elements and to reduce power consumption by connecting an emitter of a transistor (TR) of a current mirror pair of the emitter of the other TR via a resistor and connecting a resistor and a collector of the TR to it. CONSTITUTION:TRs Q1, Q2, Q4, Q5 and a resistor R1 constitute a band gap type reference voltage circuit. The reference voltage Vref is divided by resistors R4, R5 via an emitter follower TRQ7 and fed to TRs Q8, Q9. The TRQ8 switches a base current I6 of the TRQ3 to switch on/off of the TRQ3. When the relation of VB(ON)>VB8(ON) is established (where; VB(ON) is a base voltage of Q8 wherein the Q3 is turned on and VB8(ON) is a base voltage when the Q8 is turned on), the Q8 is turned on, the Q3 is turned off from on, the base voltage of the Q7 is VB(OFF) to attain VB(OFF)>VB9(ON), the output TRQ9 is turned on to attain thermal protection.

Title: Method of using x-ray picture reinforcement tube and circuitfor realizing it
Inventor: ERITSUKU MARUSHIYU
IPC: H01J31/50
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To obtain a method with no disadvantage by applying almost zero operating voltage to a photocathode when a X-ray image intensifier tube is in operation and applying higher turn-off voltage than the operating voltage to the photocathode to turn off the intensifier tube. SOLUTION: A turn-off command is applied to a logic circuit CL to turn off a X-ray image intensifier tube. The circuit CL stops the operation of a light emitting diode DEL1 of the first optical coupler OC1, operates a light emitting diode DEL2 of the second optical coupler OC2 and starts a trigger TR2. Then, voltage Ugs2 between gate sources of the second TrQ2 becomes positive and voltages Upc of a photocathode PC becomes 100U. In the meantime, a TrQ1 is turned off. When the intensifier tube becomes in operation, the voltage Vpc of the photocathode PC becomes zero. When the intensifier tube is turned off, the voltage Upc is almost zero, and when the intensifier tube is turned off, the Upc is about 1000 V. A switching circuit turns off the intensifier tube by applying higher voltage than the operating voltage to the photocathode PC.
