摘要:
In an optical disc reproducing apparatus, when an amount of light received by an optical pick-up varies or leakage light enters a light receiving portion due to the tilt of the optical pick-up or the like, a tracking control signal generation circuit adds an offset in accordance with a control value outputted from a tracking actuator controller to an output of a tracking servo filter. As a result, a tracking servo pull-in operation is performed in a state where the optical pick-up is forcibly tilted. The direction in which the optical pick-up mentioned above is forcibly tilted is determined from the result of, e.g., measuring the duty ratio of a DPD off-track signal. Therefore, a reproduction signal, a focus error signal, and a tracking error signal are correctly generated without providing a tilt mechanism in the optical pick-up.
摘要:
A method of ascertaining the state inside a melting furnace of a radioactive waste, which method comprises: blowing a gas into a molten matter in the melting furnace by using at least two slender tubes disposed at an upper and lower points with a gap .DELTA.h between said points; detecting a back pressure difference .DELTA.P at the slender tubes to determine the density .rho. of the molten matter; and determining the level h of the molten matter in the furnace using the density .rho.. It is also possible to detect the formation of a bridge inside the furnace due to a non-molten solid matter of the waste charged into the furnace.
