Title: Electric discharge lamp lighting device
Inventor: ERIGUCHI HIROYASU
IPC: H05B41/24
Filed: 1992-09-25
Abstract: PURPOSE:To provide an electric discharge lamp lighting device in simpler and inexpensive constitution while securing performance and safety. CONSTITUTION:When an electric power supply switch S2 is turned off, since electric power is not supplied from AC electric power supply Vs, voltage of a capacitance element C1 of a chopper circuit CP drops gradually, and drops lower than a lower limit value of output voltage of the chopper circuit CP. A detecting circuit Y1 detects this voltage drop, and drives a control circuit X2, and turns on a switching element S3. Thereby, a discharge resistor Rd is connected in parallel to the capacitance element C, and electric charge of the capacitance element C1 is discharged in a short time through the discharge resistor Rd. Thereby, a time when voltage is generated across an electric discharge lamp LP can be shortened. Thereby, a problem with safety is not raised. Circuit constitution can be also simplified.

Title: Dual loop servo controller for cut-off voltage of cathode-ray tube
Inventor: IBU SONTAGU
IPC: H04N5/57
Filed: 1992-08-31
Abstract: PURPOSE: To prevent a malfunction of a luminance sensor by automatically controlling the cut-off voltage of the sensor by providing a selector means which switches a first servo control loop to a second servo control loop, or vice versa, in accordance with a cathode current and luminance. CONSTITUTION: When a luminance sensor malfunctions or the colliding point of an electron beam with a fiber is erroneously positioned and a cathode current exceeds its threshold IKI, the output signal of a comparator 52 immediately sets a bistable circuit 53 to a state '0'. Therefore, a selector 59 is positioned to a position C1 and servo control is obtained by measuring the cathode current set at a value Ic. When the servo control is made by using the cathode current, a selector 65 is positioned to a position 2 and a signal SEL is inputted to a subtractor circuit 63 during dark current measurement. When the output signal of a circuit 73 stays between thresholds LUM1 and LUM2, a dual servo controller returns to servo control by means of optical measurement and the bistable circuit 53 becomes a state '1', and then, the selector 59 is positioned to a position C2.  When a cathode-ray tube is turned on, a signal ST short-circuits a capacitor Cm. As a result, a high negative Wehnelt voltage is decided to a cathode.
