Filed: 1983-01-31
Abstract: PURPOSE:To attain the offset control with high accuracy by using a fuse means to an offset control circuit and controlling the value of an offset control resistance. CONSTITUTION:Offset control resistances RL11-RL1n are connected to the collector of a differential transistor TRQ3 in series to a load resistance RL1'. The emitters of TRQ11-Q1n forming a control circuit 2 are connected to the joints of resistances RL11-RL1n respectively. Then the constant voltage Vr is applied to the bases of TRQ11-Q1n via polymeric Si resistances RF11-RF1n which function as fuse means. A circuit which is similar to such resistance circuits 1 and 2 is also provided to the collector of a differential TRQ4 at the other side. Now the offset voltage with which the output voltage Vout1 is reduced less than the Vout2 when the voltage of an equal level is supplied to the bases of TRQ3 and Q4. In such a case, a resistance KF1n is fused. As a result, the TRQ1n is turned off to increase the load resistance of the TRQ3. Then the offset voltage is offset.

Title: Control circuit of cathode ray tube luminance
Inventor: MIZUSAWA TAKESHI
IPC: H04N3/20
Filed: 1984-01-30
Abstract: PURPOSE:To prevent a seizure on a fluorescent face caused by stopping an electron beam in one point on a fluorescent face by detecting that an electron beam deflecting signal inputted to a cathode-ray tube stops from the absence of its AC components and reducing the intensity of an electron beam by a generated detecting signal. CONSTITUTION:When scanning of an electron beam stops, a signal inputted to a terminal 34 becomes a DC component or a zero volt. Namely, an AC component of a signal disappears. Since DC components are removed by capacitors 5 and 5', an inputs to amplifiers 6 and 6' become a zero volt, and a Q1 and a Q2 are turned off. As a result, a base voltage of a Q3 rises, which is turned on, and an emitter of the Q3 generates a voltage of V1-VBE. The VBE is a voltage between a base and an emitter. When a cathode-ray voltage of a cathode-ray tube is set higher than that at the time of a usual operation, the intensity of an electron beam becomes weak and its luminance is lower. The voltage V1 is set by a variable resistance 9 so that the voltage of V1-VBE can be higher than that at the time of usual operations and the intensity of an electron beam will be substantially weak.
