Title: Optical beam displacement measuring method for objective lens driver
Inventor: SEKIMOTO YOSHIHIRO
IPC: G11B7/09
Filed: 1988-12-27
Abstract: PURPOSE:To improve the detection accuracy by arranging a two-split photodetector near the position of collecting an emitting beam from an objective lens of an optical head having a light source and detecting the displacement of a beam focal position attended with the displacement of the objective lens in the tracking direction from a difference signal. CONSTITUTION:A light beam from a light source 3a is led to an objective lens 6 and a two-split photodetector 19 whose photodetecting face 19a is split into two by a separation strip 19b is arranged near the focal position of the light beam emitted from the lens 6. A light beam is radiated from the light source 3a and a prescribed voltage is applied to a tracking coil 15 to drive the lens 6 in the tracking direction together with a mirror barrel 9. Then the optical axis of the lens 6 is displaced to displace the focal position of the light beam. Thus, a deviation is caused to the light beam spot location on a photodetection face 19a and a displacement detection signal is outputted from an operational amplifier 20. Thus, the transmission characteristic of the displacement of the radiated beam with respect to an input voltage to the coil 15 is detected with high accuracy based on the prescribed calculation.

Filed: 1987-12-26
Abstract: PURPOSE:To reduce a longitudinal noise by inserting a first transistor between input and output ends, inserting a detection circuit to detect voltage variations between input and output ends and providing a by-pass circuit thereto. CONSTITUTION:An electronic choke circuit 11 is connected between the power supply 2 and a load side circuit 3. The choke circuit 11 is equipped with a transistor(TR), constant voltage diodes ZD1 and ZD2, resistors R1 and R11 and a capacitor C. A detection circuit is constituted of the constant voltage diode ZD1, resistors R2 and R3, a TR 2 and resistor R4. Variations in voltage across terminals A and C are detected to control a TR 1 by the TR 2. Accordingly, the increase in voltage drop in the resistor R1 due to the increase in the current of the resistor R1 is offset by the decrease in voltage drop of the TR 1, so that the voltage drop between the terminals A and C is kept constant. While, a detection circuit constituted of resistance R6, a TR 3, the constant voltage diode ZD2, the TR 4 and so on controls the TR 3 and keeps the voltage drop between terminals B and D constant.

CONSTITUTION:Regarding the formation of a fluorescence screen of a color picture tube that forms a light absorbing layer 38 that has a matrix hole 37 correspondent to a circular transparent hole 21 of a shadow mask 3 on the inner surface of a rectangular panel 1, light is radiated from a light source part 28 to a photosensitive agent layer 34 formed on the inner surface of the panel 1 through the shadow mask 3, and when a pattern correspondent to the circular transparent hole 21 of the shadow mask 3 is thus baked, the longitudinal length of the light source part 28 is determined as 0.7-1.5 times as wide as the orthogonal side. The longitudinal side of the light part 28 is arranged in such a way that it is matched with the long axial direction of the panel 1, and the pattern correspondent to the circular transparent hole 21 of the shadow mask 3 is baked on the photosensitive agent layer by the light from the light source part 28.
